Surrey County Council Southern Rail Access to Heathrow Final Report
Weybridge to London Waterloo via Virginia Water services that have to be removed (also noting these services would have to be removed to support 4tph to London Waterloo).
The remainder of the infrastructure options look at resolving the level crossing
capacity issue and improving journey times, by providing alternative routeings
avoiding some or all of the level crossings. By removing the need for the
Heathrow services to be routed through the existing infrastructure and level
crossings this also gives the potential to allow for service levels to Heathrow
from Surrey to be enhanced.
Between Chertsey and Woking, the existing curve between Byfleet Junction and Addlestone Junction is currently used operationally as a holding point for freight
trains. The introduction of new services between Heathrow and Woking along this
section of track could necessitate providing a new facility to hold freight services such as an additional freight loop located between Virginia Water and Byfleet.
5.1.5 Capacity on the South West Main Line
The Network Rail Study has assumed capacity enhancements on the South West
Main Line are delivered as a requirement to increase capacity to London Waterloo from Surrey and Hampshire. The following infrastructure schemes would be
required to provide capacity for SRAtH on the South West Main Line (SWML) Slow Lines between Byfleet Junction and Woking:
For all options (to the south):
Grade separation of Woking Junction;
Additional platform at Woking Station; and
Provision of a new freight regulation point, for example between Virginia Water Addlestone Jn.
For options with services to Guildford:
Track alterations at Guildford; and
Additional platform (s) at Guildford.For options with services to Basingstoke:
Grade separation of the Basingstoke Great Western Junction.
What is not made clear is the extent to which the capacity available will be
prioritised for trains to Heathrow. Whilst the Network Rail analysis identifies that the largest potential demand for services to Heathrow from Surrey is from
catchments such as Woking, Guildford and Weybridge it is important to remember that significantly higher levels of passenger demand remain for services
into London via Waterloo (see Demand Assessment section).
The Wessex Route Study identifies that capacity through Woking station (if Woking Junction was improved) would reach 32tph but there may need to be trade-offs between serving London Waterloo and serving Heathrow.

5.2 SRAtH Train Service Options
The Network Rail report outlines several possible train service options dependent
on which infrastructure option is chosen. In general, all options seek to
accommodate up to 4tph between Heathrow and London Waterloo with various
journey time opportunities. Provision of services to Surrey and Hampshire vary
between infrastructure options as outlined in Table 7, but generally where
provision is possible these services can operate in any combination to
Weybridge, Basingstoke or Guildford.
The current journey times for services between Woking and Staines have been
provided for comparison, the journey time is based on the minimum journey times for non-stopping services and an all-stops service. All other timings included have
been taken from the Network Rail study.

Surrey County Council Southern Rail Access to Heathrow Final Report
The main impact on existing train services in Surrey is that in all options the
existing 2tph Weybridge to London Waterloo stopping service via the Windsor
Lines (Hounslow loop) is removed to enable services to be operated between
Heathrow and London Waterloo. Network Rail suggests that this is replaced by a
Weybridge-Virginia Water shuttle service to replace some of the lost
connectivity, as well as additional Surrey-Heathrow services.
The study also considers the potential to link SRAtH services to trains serving Heathrow from the Great Western Main Line.
Network Rail’s report presents three service options with regard to SRAtH to Surrey and the south. The service options offer services to any pair of three
destinations: Guildford, Basingstoke or Weybridge. The following diagrams
outline the three service options presented in the Network Rail report.

5.3 Alternative Service Options
Arup has developed alternative service options to improve Surrey service connectivity with SRAtH from that proposed in the Network Rail report. The
Arup options involve improving connectivity to Weybridge making use of the proposed Weybridge Chord.
5.3.1 Enhanced Connectivity
The Network Rail options provide capacity for up to 4tph between Heathrow and
either pairings of the following destinations: Basingstoke, Guildford and
Weybridge. The Weybridge chord option potentially provides half hourly (2tph)
connectivity to all three destinations, by making use of the existing Weybridge
Bay Platform 1, and providing an additional infrastructure alignment to connect
the Bay Platform to the SWML Slow Lines via the grade separated Byfleet Jn.
The infrastructure alignment allows trains from the Bay Platform to access the
Down Slow Line without conflicting with services on the other SWML lines.

05 ARUP REPORTS\REPORT\SURREY SRATH - FINAL REPORT - DEC 2016.DOCX
Surrey County Council Southern Rail Access to Heathrow Final Report
It is proposed that 1-2tph from Heathrow to Surrey/Hampshire could be routed via
a reversing move to serve Weybridge station. Figure 19 provides a schematic train
service map, with the option of reversing 2tph Basingstoke – Heathrow services at
Weybridge. Stopping airport services at Weybridge provides additional
connectivity options, and could off-set some loss in connectivity on the Chertsey
Line by proving a station interchange at Weybridge. The reversal of services in
the Bay Platform could however increase journey times by approximately 10
minutes.
This option could be developed alongside Option 1b, 2 or 3 in the Network Rail study, however with Option 3 it could result in the loss of connectivity between Virginia Water and Weybridge.
Figure 19: Weybridge Chord option indicative schematic train service map.
5.3.2 Surrey Service Enhancement (with Option 3)
Should the Network Rail Option 3 infrastructure be taken forward, further train
service options could be developed beyond that outlined in the Network Rail
study. These service options would the designed with the objective of improving
rail access from Surrey/Hampshire to Heathrow as a higher priority than services
between Heathrow and London Waterloo. Assuming existing services from the
GWML to Heathrow T5 remain, the maximum capacity available for SRAtH
services is 8tph. 6tph of the 8tph could be routed towards Surrey/Hampshire and
2tph between Heathrow and London Waterloo. Capacity is provided for the 6tph

Surrey County Council Southern Rail Access to Heathrow Final Report
towards Surrey/Hampshire by making use of the Option 3 alignment joining the
existing rail network at the Chertsey line. The 6tph to Surrey/Hampshire option provides 2tph to each destination: Weybridge, Basingstoke and Guildford. Figure
20 outlines a train service map of this option.
Figure 20: Surrey Service Enhancement (with Option 3) indicative schematic train service map.
Inclusion of the Staines chord (Option 1b) could further enhance this option allowing for 2tph (of the 6tph) to serve Virginia Water and Egham as stopping
services whilst the remaining 4tph operate as fast limited stop services from Woking. Capacity for freight services also would need further consideration with
this option due to the increased utilisation of the Chertsey Line.
Although this option reduces the number of trains between Heathrow and London
Waterloo, reducing direct connectivity from stations such as Twickenham and
Richmond, it could also present less of a performance risk to the Windsor Line
services between Staines and Feltham. This option does however, also require the
most expensive infrastructure option presented and could increase both
operational and capital costs impacting on the overall business case, however it
represents the highest level of service connectivity to Surrey.

5.3.3 Airtrack and Airtrack-Lite
Airtrack
Previous proposals to link the Wessex rail network to Heathrow Airport include
Airtrack and Airtrack-Lite. Both schemes presented infrastructure options similar to Options 1a and 1b presented in the Network Rail study. The Airtrack scheme
was suspended in 2011.
The proposed service specification for Airtrack is summarised below:
2tph between Heathrow T5 and London Waterloo (semi-fast);
2tph between Heathrow T5 and Guildford (1tph at peak times) semi-fast;
2tph between Heathrow T5 and Reading semi-fast; and
Extension of the current Heathrow Express services to Staines (from T5).
The scheme differs to the proposed service options in the Network Rail report by
providing services between Reading and Heathrow T5 (via Bracknell), and
fewer services towards Woking and London Waterloo whilst maintaining
existing services. The majority of the airport services were proposed as semi-fast
limited stop services, presenting potential issues regarding the capability of the
infrastructure to support this alongside the current service levels. The proposal to
link Reading to Heathrow via Bracknell is potentially no longer required should
the development of the Western Rail Link to Heathrow proceed, which provides
an alternative link to Reading via the Great Western Main Line.
As noted previously, a significant issue raised against the Airtrack scheme was
the impact of additional services on level crossing barrier down times, particularly between Staines and Virginia Water where an additional 4tph were proposed in
each direction.
Airtrack-Lite
Airtrack-Lite is a subsequent proposal put forward by Wandsworth Council that
looked to resolve some impacts of the increased barrier down time as a result of
additional services on the Waterloo to Reading Line. Airtrack-Lite proposed
utilising existing services instead of additional services by splitting services from
London Waterloo with one portion of the train heading to its original destination and
the remainder to Heathrow. It also removed the Airtrack proposed services linking
Reading and Guildford to Heathrow, leaving links to London Waterloo and
Weybridge only. The Weybridge – Heathrow services proposed in Airtrack-Lite
would be rerouted to Heathrow rather than serving London Waterloo, reducing
connectivity and service provision between Staines and London Waterloo. The
Airtrack-Lite scheme is no longer being actively developed.

Surrey County Council Southern Rail Access to Heathrow Final Report
5.3.4 Heathrow Southern Rail
Heathrow Hub Ltd has proposed a scheme called Heathrow Southern Rail (HSR) for providing rail access to Heathrow from the south. The infrastructure proposals developed for this scheme are very similar to Network Rail Option 3.
The proposed train service is also similar to that in the Network Rail study
providing 4tph between Heathrow and London Waterloo, 2tph between
Heathrow and Basingstoke, and 2tph between Heathrow and Guildford. The
proposals also recommend continuing the 4tph from Basingstoke and Guildford
through the airport to London Paddington in replacement of the current Heathrow
Express services as well as potential extensions to the south coast such as
Portsmouth and Southampton. The extension through Paddington offers the
potential benefit of providing interchange with Crossrail services with High
Speed 2 services at Old Oak Common.
One of the main differences between the Heathrow Hub HSR proposal and that set
out in the Network Rail study are the journey times to the airport. The Heathrow
Hub HSR proposal recommends non-stopping services between Basingstoke and
Guildford to Heathrow, with the exception of stopping at Woking, to reduce the
journey times as much as possible. The Heathrow Hub HSR proposal states a
potential journey time from Woking to Heathrow T5 station of 16 minutes,
compared to the Network Rail study time for Option 3 of 23-28 minutes, which is
a considerable journey time saving. It is understood the main difference between
the two is that the Network Rail study assumed services would stop at all
intermediate stations between Woking and Heathrow.
Achieving fast paths between Guildford/Basingstoke and Heathrow may be
limited on the SWML due to timetabling constraints. Detailed timetable analysis
including future assumptions regarding Crossrail 2 and other capacity
improvements on the SWML would be required to confirm the potential journey
time savings possible with limited stop services. A reduction of intermediate stops
may reduce attractiveness to local users where a change of trains at Woking would
be required.
5.3.5 London Borough of Hounslow Proposal
LB Hounslow submitted a pre-feasibility report for southern rail access to
Heathrow T5 in August 2015. Their work also included a feasibility study for a
new station in the Bedfont area. The train service proposals for services between
London Waterloo and Heathrow are similar to that in the Network Rail report
providing a 4tph service, however with the additional of all services calling at the
proposed Bedfont station. In regards to the proposals for services towards Surrey,
there are no specific recommendations however given the infrastructure option
does not avoid the level crossing in the Egham area the service level would be
limited to 2tph in the peak hours with up to 4tph in the off-peak hours (impacting
off-peak level barrier down time). With the proposed alignment this option would
present the slowest journey times from Surrey and the south to the airport,
requiring an additional stop at Staines, potentially Ashford and the proposed
Bedfont station as well as travelling further to Heathrow T5 compared to the other
options considered.

Surrey County Council Southern Rail Access to Heathrow Final Report
5.4 Cross Heathrow Connections
The Network Rail study briefly outlines opportunities to provide cross-airport
connections to the Great Western Main Line (GWML) utilising the current Heathrow Express trains paths. The Network Rail study indicates that running
Surrey/Hampshire services through Heathrow T5 to London Paddington generates increased benefits.
Through services are also proposed as part of the Heathrow Hub HSR scheme as
an alternative route to London and Old Oak Common (for HS2). Without
operating SRAtH services through the airport towards the GWML, it would not be
possible for SRAtH services to serve Heathrow Central (T1,2,3) due to capacity
constraints with Crossrail services to T4, assuming a ~15 minute service
frequency remains for both Crossrail and Heathrow Express paths.
A brief review of Network Rail’s Western Route Study also outlines several
scenarios which could affect cross-airport connectivity including the proposed
CP6 Western Rail Link to Heathrow (WRLtH). WRLtH is a proposed scheme for
CP6 currently under development, which proposes the provision of a new rail
link between the Heathrow T5 station and the GWML between Iver and Langley.
The WRLtH includes up to 4tph between Heathrow T5 and the GWML towards
Reading and potentially to destinations such as Oxford, Swindon and Newbury.
The Western Route Study outlines several choices for funders regarding making best use of the capacity between London Paddington and Reading, some of which
affects how Heathrow Airport is served and subsequently could affect the choices available for linking services at the airport. For example choice A1b in the
Western Route study, suggests;
“Optimising Main Line passenger capacity could be achieved through the
utilisation of paths [on the Main Lines] for long distance services rather than
dedicated airport services. This supports the principle of harmonising rolling
stock types and maximising the passenger capacity of the Main Lines by
allowing longer trains to run that carry more passengers, particularly in the
peak periods.”(Network Rail, Western Route Study, Final, 2015)
This choice suggests that the current Heathrow Express paths could be operated
on the Relief Lines between London Paddington and Heathrow, to provide
additional capacity for services beyond Reading on the Main Lines. It is
feasible that operating the Heathrow Express services on the Relief Lines could
mean these services run as Crossrail services beyond London Paddington from
central London providing 8tph.
Linking services from SRAtH to Crossrail services at Heathrow Airport will likely result in significant risk to performance of these services, especially with

Page 49
Surrey County Council Southern Rail Access to Heathrow Final Report
Crossrail operating up to 24tph in the central core section7. In the scenario
(A1b) outlined above with potentially 8tph between Crossrail and Heathrow it is likely that cross Heathrow connections would not be possible based on the potential impact to performance.
The remaining choices for linking services therefore remains with the existing
service scenario of 4tph between London Paddington and Heathrow T5 operating
on the GWML Main Lines, in between Long Distance High Speed (LDHS)
services from the west. Potentially cross airport links to the WRLtH and SRaTH
are possible in any combination, however linkages of these services with SRAtH
will introduce additional cross route performance risks which will need further
detailed consideration should this be taken forward particularly given both routes
will operate at or near capacity in the peaks. Opportunities may exist to mitigate
risks such as turnback facilities in the vicinity of the airport or possibly at Staines.
Further consideration as to the attractiveness of linking services between SRAtH
and the GWML to London Paddington would be required given the Airport
services have a different passenger demand profile to that of commuters for
example. Airport services will tend to require extended dwell times due to
passengers with flight baggage, and potentially the train layouts would not be
based on a commuter profile (e.g. high-density)8.
7 The central operating core of Crossrail between London Paddington and London Liverpool Street is
planned to operate up to 24tph, with various service grouping between destinations. Punctuality of the
Crossrail services at key locations is critical to ensure the correct ordering of services to ensure the level
of service is sustainable and that all destinations are served. A delay event at Woking for example could
result in a Crossrail service arriving into the central operating core late a subsequently missing its slot in
the timetable, reducing service frequency though central London and potentially not reaching its
destination (due to constraints on the East Anglia Lines).
8 Crossrail services although serving the airport are likely to have an interior layout designed for high-density in-train capacity.

6 Demand Assessment
6.1 Network Rail Demand Forecasts
Network Rail presents demand forecasts in its Feasibility Report. It provides the following information:
A southern rail access link to Heathrow generated significant demand and revenue under even the most conservative Heathrow two-runway capacity scenario. Delivery of the Conditional Outputs could facilitate an additional 8.9m annual rail trips in 2033/4, of which 4.8m were airport journeys, growing the expected number of Heathrow airport journeys by rail from approximately 17m to 22m by 2033/34 of a total 56m passengers per annum.
The most valuable Conditional Outputs were Waterloo-Heathrow services,
the next most valuable Conditional Outputs were for services via Woking to Guildford and Basingstoke. Serving Basingstoke via SRAtH would only be beneficial if the service provides a significantly better service than a service via a Western Rail Access to Heathrow link. All other Conditional Outputs were forecast to deliver significantly lower benefits.
Serving the Guildford and Basingstoke markets brings higher user benefits
for both Heathrow and non-Heathrow journeys than serving the Guildford and Weybridge markets.
When a direct Terminals 2 and 3 call was added to the Surrey/Hampshire
services, the user and non-user benefits for Heathrow journeys were much higher.
When Surrey services are extended through Heathrow to London
Paddington, there is an increase in both benefits and revenue for Heathrow and non-Heathrow journeys.
It is not the final destinations of Waterloo, Guildford and Basingstoke that
provide the majority of the economic benefits in the Market Study findings but instead it is intermediate stations (such as Richmond, Twickenham and Farnborough Main) and the interchange opportunities at Clapham Junction and Woking.
To validate the demand assessment findings from the feasibility study, we provide below information about travel demand to Heathrow from Surrey.
6.2 Demand from Surrey
6.2.1 Passenger Demand
Heathrow Airport had 75m passengers in 2015; of which 51m (68%) were terminating passengers and the rest transited to other flights.

Surrey County Council Southern Rail Access to Heathrow Final Report
Of the 51m annual trips to the airport, it is estimated that 2.0m (4%) passengers were from Surrey.
Leisure traffic represents the majority of Heathrow demand, with about two thirds (64%) of passengers travelling for leisure. 93% of flights at Heathrow are international, with just 7% domestic.
Surrey residents make on average about 3.5 air passenger trips per year, with 1.65 trips per year to Heathrow Airport. The higher trip rates tend to be nearer to the
airport from Elmbridge, Guildford and Runnymede districts. 44% of the Heathrow
passengers travelling from Surrey are residents of these three districts. The total passengers per year from Surrey districts to Heathrow is shown in Figure 21.

6.2.2 Airport Employee Demand
Over 70,000 people work at Heathrow Airport, of whom 10,380 (14%) live in Surrey. The majority of them are from Spelthorne (38%), Runnymede (17%) and Surrey Heath (13%).
About 80% of the airport employees who live in Surrey live within 20km of the
airport. More than half (55%) of the Heathrow employees who live in Surrey are
air cabin crew, maintenance tradesmen and other skilled workers (apron, ramp, cargo, drivers, and baggage staff), 19% are passenger services, sales and clerical
staff, and 6% are management professionals.
82% of the Heathrow employees who live in Surrey drive to work at the airport and most travel without passengers. 6% travel by bus whilst the proportion

6.3 Future Growth
6.3.1 Surrey
Surrey has a resident population of 1.14 million people. The main towns in Surrey
are Guildford (73,779 population) and Woking (69,079). Other main population centres include Ewell (42,791), Camberley (33,571), Farnham (39,488) and
Redhill (30,289).
Surrey’s population is forecast to grow by 9% to 2031 (equating to an average
annual population growth rate of 0.45%). At a Borough level, the most growth is
expected in Runnymede (14%), Elmbridge (13%), Reigate & Banstead (13%),
and Epsom & Ewell (11%). The main centres of Woking and Guildford are both
expected to grow by +10%. Surrey’s forecast population change to 2031 is shown

The Civil Aviation Authority (CAA) data indicates that the number of passengers
at Heathrow Airport has increased by 6.3m (9%) from 67.1m in 2004 to 73.4 in 2014. Heathrow is already operating at over 98% of its 480,000 annual Air
Transport Movements (ATM) capacity. The growth is driven by incremental
increases in the average aircraft size operating at Heathrow.
Without the third runway, the growth in passenger numbers at Heathrow is forecast at 11% to 82 million passengers per annum (mppa) by 2030 and at
16% to 87mppa by 2040. Heathrow’s passenger forecast without the third runway is shown in Table 10.

6.3.3 Future Demand to Heathrow from Surrey
Of Heathrow Airport’s 51m terminating passengers, about 2m are travelling from Surrey which is estimated to grow at 9% to 2.2mppa by 2030 and at 16% to 2.3mppa by 2040 without the third runway. With the third runway, the growth in
passenger numbers at Heathrow is forecast at 39% to 2.8mppa by 2030 and at 73% to 3.5mppa by 2040.
Over 70,000 people work at Heathrow Airport, of which 10,380 (14%) live in Surrey. The number of employees from Surrey is not expected to grow without
the third runway, however it is predicted that the employee numbers will increase to 12.6k (+23%) by 2030 and to 15.4k (+50%) by 2040 with the third runway.

05 ARUP REPORTS\REPORT\SURREY SRATH - FINAL REPORT - DEC 2016.DOCX
Surrey County Council Southern Rail Access to Heathrow Final Report
With the current passenger rail mode share (4%), the number of Heathrow rail
passengers from Surrey could therefore increase by approximately 7.5k to 87k in 2030 and by approximately 13k to 92.8k in 2040 without the third runway. If it is
assumed that the passenger rail mode share from Surrey will increase to 10%, the number of passengers could increase to 219k and 232k per annum.
With the third runway, the rail passengers are expected to grow by 31k in 2030 and 59k in 2040 with the current rail mode share and to grow by 77k and 147k with higher rail mode share.
The predicted number of passengers and employees with and without the third runway are shown in Table 12.

6.4 Demand beyond Heathrow from Surrey
Surrey provides about 3% of Greater London’s workforce. According to the Surrey Local Economic Assessment, around 64% of Surrey residents work within the County. For those that commute out of the county, London is the most
common destination (with 134,200 people or 12% of the Surrey population commuting to the capital).
7% of Surrey workers commute to Outer London boroughs – Hillingdon,
Hounslow and Kingston upon Thames being the most common. A further 5%
commute to Inner London boroughs – principally Westminster and the City of
London. For commuting to central London the most significant flows include the
City of London and Westminster from Tandridge & Woking, and to Westminster
from Tandridge, Woking, and Reigate and Banstead.

Surrey County Council Southern Rail Access to Heathrow Final Report
6.4.1 Cross Heathrow Journey Times
The potential benefit of running trains beyond Heathrow to London Paddington
(either directly or via interchange) are to provide direct access from Surrey into
London, as an alternative to London Waterloo. The additional connectivity and
resilience in the event of disruption to Waterloo is a clear benefit for Surrey, and
modelling by Heathrow Southern Rail indicates that the majority of passengers
on its services (~90%) are accessing destinations beyond Heathrow (i.e.
interchanging at London Paddington or Old Oak Common for underground or
Crossrail services to central London.
Analysis above shows that the key destinations in central London for Surrey
commuters are Westminster, the City, Camden (West End) and Tower Hamlets
(Canary Wharf). These locations are more accessible from London Waterloo than
they are from London Paddington, as shown in Table 14. The analysis considers
journeys from Woking and Virginia Water to central London destinations via
London Waterloo or via Heathrow assuming either Network Rail proposed
services (i.e. stopping services) or Heathrow Southern Rail proposed services
(non-stop from Woking to Heathrow). It indicates that it will be significantly
quicker to travel via London Waterloo than via Heathrow for all journeys from
Woking (i.e. via the SWML). From Virginia Water it is quicker to travel via
London Paddington for all destinations (except Bank) due to connections to
Crossrail. The Heathrow Southern Rail option does not propose stopping at
Virginia Water.

in future. Although this could be offset by the inconvenience of sharing commuter trains with air passengers and potentially long dwell times at Heathrow

and Woking.
The above assessment indicates that the Network Rail forecasts look generally
sensible and there are no major issues. The only necessary clarification is why serving the Guildford and Basingstoke markets brings higher user benefits than
serving the Guildford and Weybridge markets, which needs discussion with Network Rail.
Given the higher levels of demand to Heathrow from Elmbridge, Guildford,
Runnymede and Woking boroughs in Surrey, we should ensure that these areas are well served by the southern rail link and not excluded at the expense of longer
distance services.
It is also important to note that passenger demand for Heathrow Airport is
significantly lower than residents demand for commuting to London from
Surrey, as shown in Figure 25. We estimate that annual commuting demand to
London from Surrey is in the order of 33m trips per year, whereas total Heathrow
passenger demand is 2m, with rail significantly less (14m vs 0.08m). London
commuting demand is forecast to grow significantly whereas, without a third
runway, Heathrow demand is not expected to grow to the same extent. This is
important to note in considering priority for train paths for Heathrow vs SWML
services or Windsor Lines services to London Waterloo.

7 Option Assessment
The scope of this study is to use available data to robustly assess the SRAtH
options presented by Network Rail and comment on whether their key statements and claims are reasonable. The study also considers alternative options for
SRAtH from Surrey and provides a high level assessment of their feasibility.
The study was limited to information in the written report from Network Rail and
further details (e.g. cost assumptions) could not be provided on request, thus limiting the assessment. Therefore conclusions are based on the available
information and where there is uncertainty this is highlighted and further engagement or analysis recommended.
Table 16 summarises the options reviewed and the impacts on Surrey, both positive and negative.

7.1 Value for Money
There is significant variability in the value for money between the assessed
schemes, reflected in the large range in benefit cost ratios. This variability is
primarily reflected through the benefits associated with the different service patterns that each option facilitates and the areas to which they provide
greater connectivity to Heathrow.
The benefit cost ratios are significantly higher for schemes where services to London are prioritised as this is where a higher proportion of Heathrow demand originates from. In addition, the infrastructure requirements to facilitate Heathrow – London services on the SWML are significantly lower than that required to
facilitate services between Surrey/Hampshire destinations. Options that facilitate
Surrey/Hampshire services will either require a greater length of tunnelling,
viaduct or additional chord infrastructure and will not be solely operating along
pre-existing rail alignments. Analysis indicates that the scale of demand from
London and benefits associated with operating faster, more frequent and more

DATA\4-05 ARUP REPORTS\REPORT\SURREY SRATH - FINAL REPORT - DEC 2016.DOCX
Surrey County Council Southern Rail Access to Heathrow Final Report
direct services to London destinations, is able to comfortably offset the initial
infrastructure costs incurred. The analysis from Network Rail reveals that in
many cases, the intermediate stations served on the route into London (Richmond,
Twickenham) actually provide the majority of these benefits, so connecting these
areas is an economic priority. The operation of semi-fast stopping patterns to
London provide the greatest overall value for money by providing the greatest
time savings between Heathrow and London destinations.
In the case of Surrey/Hampshire destinations, the benefits of operating these
services are comparatively lower and are not sufficient to offset the additional infrastructure costs required to facilitate them. However,
establishing Surrey/Hampshire services better meets the strategic goals behind the SRAtH concept.
Table 18 summarises how the BCR values vary between the operation of London
only services and Surrey/Hampshire only services, despite using the same
infrastructure. It also shows how a combination of both services can still generate value for money, while also ensuring that greater connectivity to Heathrow is
established from both localities.

7.2 Summary of Options
The recommendations for each infrastructure option following the detailed
assessment undertaken as part of this study are included below. For each option
Network Rail Option 1a does not provide any rail service to Heathrow for Surrey but does impact on existing services, as the Weybridge to London via the Windsor Lines service is removed. Surrey (the County Council and its stakeholders) should therefore object to this option.
Network Rail Option 1b provides a reasonable service from Surrey to
Heathrow (2tph in the peaks and 4tph off peak), although a decision would
need to be made on how this splits between Guildford and Basingstoke in the peak (i.e. 1tph to both or 2tph to Guildford). This option has the longer
journey times, results in the loss of the Weybridge service, and has a level crossing impact in the off peak. It is the lower cost option and has the best
BCR of the Network Rail options. This is the best of the Network Rail options presented, but our view is that Option 1c could perform better, so
this option is not supported. Network Rail Option 1c provides a 4tph all day service with potentially
lower costs of Options 2 and 3 (£0.5bn difference between 1b and Option 2 & 3). This means it could produce a positive business case. This option could also be developed incrementally as a second stage delivery following Option 1b. The feasibility of level crossing replacement or closure needs further

Surrey County Council Southern Rail Access to Heathrow Final Report
assessment in order to understand the costs and impact on road traffic before
further development of this option takes place. This option should therefore be retained for further consideration.
Network Rail Option 2 provides a better service from Surrey to Heathrow
with 4tph at all times. It avoids level crossing impacts in the Egham area, although this is at the expense of serving Egham station. It is a very high cost option and has a lower BCR. It does result in the loss of the Weybridge service but this could be offset with the Arup proposal to serve Weybridge using the Bay platform, although at an additional cost. This option has benefits for Surrey, but the poor BCR and high cost indicate that it should not
be supported. Network Rail Option 3 is similar to Option 2 but provides a slightly faster
service at the expense of missing out Virginia Water. It also has a very high cost and poor BCR (with Network Rail stopping service pattern), and there is potentially and large cost risk from compensation from properties affected on the route. This option should therefore not be supported by Surrey.
Network Rail Option 4 does not provide any rail service to Heathrow for
Surrey but does impact on existing services, as the Weybridge to London via the Windsor Lines service is removed. Surrey should therefore object to this option.
Airtrack and Airtrack Lite require a similar infrastructure alignment to
Options 1a and Option b, however the Airtrack schemes proposed additional services over and above existing levels, impacting significantly on level
crossing barrier down times. The Airtrack-Lite scheme rather than increase services through the Egham area, proposed to split and join existing service
at Staines. This would result in negative impacts on journey times, and reduce on-train commuting capacity for locations to the west of Staines.
Neither of these options should be supported by Surrey. Heathrow Southern Rail presents an infrastructure alignment similar to
Network Rail Option 3 whereby the alignment bypasses Egham and Virginia
Water and joins the Chertsey Line (between Chertsey and Virginia Water).
The proposals include operating fast services from Guildford and Basingstoke,
stopping only at Woking. The proposals also include operating through
Heathrow Airport to London Paddington presenting a connectivity benefit to
Surrey passengers to central London and HS2. The resulting BCR is
reportedly very high (6.8). There are a couple of potential drawbacks for
Surrey from this scheme. Firstly it limits connectivity from other Surrey
stations such as Weybridge, requiring passengers to interchange at Woking.
Secondly, it introduces potential performance risk by joining two routes
operating at near maximum capacity during peak hours. However, despite
these potential drawbacks, this scheme performs better than the Network Rail
options and should therefore be retained for further consideration. London Borough of Hounslow proposals in terms of services towards Surrey
and the south presents the slowest journey times to the airport. The level of service is also limited as with Option 1b during the peak hours to 2tph due to the level crossings in the Egham area. With a cost estimate of £900m, this

DATA\4-05 ARUP REPORTS\REPORT\SURREY SRATH - FINAL REPORT - DEC 2016.DOCX
Surrey County Council Southern Rail Access to Heathrow Final Report
option offers limited improvements to the options presented in the Network
Rail report for Surrey. This option however, could potentially be supported by the proposed development at Bedfont.
7.3 Scheme Funding
The final issue for consideration is funding. Network Rail states in its report that
the options are currently not funded and implies that third party funding is
required for the project to proceed. By contrast, the Heathrow Southern Rail
business case report suggests that if the project can be made large enough (i.e.
providing services beyond Heathrow to Paddington and Old Oak Common), then
it could be attractive for private sector funding. It states that the scheme would be
procured and financed privately, funded against a predictable long term revenue
stream (if the latter could be committed by the DfT and TfL to purchase a defined
quantum of train paths at a predetermined price).
This indicates that the Heathrow Southern Rail option would not require a
financial contribution from the public sector, although contributions may be
required for enabling infrastructure, such as Woking junction grade separation. If
the promoters can demonstrate that there would be no major impacts to Surrey rail
services and the concerns over connectivity can be addressed (e.g. potentially
introducing an additional stop between Woking and Heathrow) then this could be
more attractive than publicly funded options. This is consistent with recent announcements by Network Rail on private sector
financing of rail projects9, and establishing a private ownership agreement for
the infrastructure could help to transfer some of the cost risks away from the public sector and reduce overall contributions.
9 In its ‘Transformation Plan’ (Network Rail, July 2016) it states that ‘We are also looking at
how the private sector might help in the delivery, financing and operation of discrete elements of our network’ such as the construction of a new piece of railway.

8 Conclusions and Recommendations
Our conclusions and recommendations from the above analysis and assessment are presented below.
8.1 Conclusions
The Southern Rail Access scheme supports Surrey’s rail
development objectives
Overall, SRAtH supports Surrey’s rail development objectives by enabling:
A fast and direct rail link to the airport from Surrey that increases its attractiveness as a prime location for global and national businesses;
Connectivity between the county and the 70,000 jobs that exist in and around
the airport, helping to further drive economic growth; An alternative to road-based modes for travel to the airport, helping to
reduce the number of vehicles using the road network which would significantly improve localised air quality; and
An improved public transport linkage and increases in county rail capacity that
helps to accommodate sustainable population growth.
However in developing and supporting the SRAtH scheme, it is important to ensure that it can be demonstrated to provide good value for money, be affordable to public and private stakeholders, and have acceptable impacts in Surrey.
Specific outputs are required from the Southern Rail
Access scheme
Our review of previous studies indicates that the following outputs should be achieved in order to fully meet Surrey’s rail development objectives:
New rail infrastructure between the South Western rail network and Heathrow Airport that provides for, preferably, direct rail services between Surrey and Heathrow Airport;
Fast and frequent rail services between Surrey and Heathrow Airport, with fast
defined as reliable journey times between Woking and Heathrow of 30 minutes or less, and frequent defined as four trains per hour;
Potential to run directly beyond Heathrow to Old Oak Common (for
interchange to HS2 in future) and to London Paddington (for connectivity to central London); and
Sufficient stopping points in Surrey to provide convenient access for
travellers to Heathrow from all parts of the county.

Surrey County Council Southern Rail Access to Heathrow Final Report
There are options that have the potential to deliver these outputs
for Surrey
Based on the available information from the different studies, there are infrastructure / service option combinations that appear to have the potential
achieve the outputs identified above.
The option that appears to have the best overall business case and benefits for Surrey is Option 1c Western Alignment plus Staines Chord with the Egham level crossings removed or replaced. This is because it has:
The lowest cost infrastructure solution; The potential to be delivered incrementally (i.e. the link to Heathrow and
Staines Chord can be delivered first, providing 2tph to Surrey in the peak period and 4tph off peak, and this can be increased to 4tph in the peak when the level crossings are removed or replaced;
The potential to operate a range of service options that best serve key areas
of Surrey/Hampshire and unlocking further potential for growth; A mix of fast and semi-fast services (exact stopping points to be determined);
and A potential new connection to London Paddington with competitive journey
times to existing London Waterloo services.
An alternative option is the Heathrow Southern Rail scheme which has a higher cost
but potential to also have a good business case and provide similar benefits to Surrey.
This option uses the same infrastructure as Network Rail option 3, but the service
pattern has faster services to Heathrow (non-stop from Woking) and runs beyond
Heathrow to Old Oak Common and London Paddington. This scheme:
Avoids level crossing issues completely; Provides fast service patterns to Heathrow and beyond; and Has higher costs due to the viaduct route, but could potentially offer good
value for money if journey time improvements are substantial over the long.
This option does have limited connectivity to stations within Surrey, due to the
reliance on the operation of limited-stop service patterns. This could can be
resolved by assessing the potential for additional station stops and to more
precisely ascertain what effect these would have on overall scheme value for
money and service journey times. A review should also be undertaken into
whether a viaduct or tunnel would be the best type of infrastructure for this option,
taking into account land impacts and mitigation costs.
There is a need for further testing of these options on a consistent
basis
One of the issues from our review is that the infrastructure options have been tested with different service pattern options. For example, Network Rail generally tested infrastructure options with stopping services to Heathrow whereas

DATA\4-05 ARUP REPORTS\REPORT\SURREY SRATH - FINAL REPORT - DEC 2016.DOCX
Surrey County Council Southern Rail Access to Heathrow Final Report
Heathrow Southern Rail tested infrastructure options with fast services to
Heathrow and beyond. Both parties used different assessment tools and this is
reflected in the range of benefit cost ratios reported in the option assessment. The
infrastructure/service options identified above need to be tested on a consistent
basis so that infrastructure options can be consistently compared using similar
service patterns, and service patterns can be optimised using consistent
infrastructure options. This means using the same demand forecasting tool and
the same service patterns for different infrastructure options.
8.2 Recommendations
Given the above, our recommendations for Surrey County Council are as follows:
Engage with stakeholders to build support for the SRAtH scheme – this
includes Surrey County Council political leadership, Surrey boroughs and districts as well as neighbouring authorities (e.g. Hampshire) and relevant LEPs);
Promote supporting schemes needed to enable SRAtH – the schemes
identified in this report required to enable SRAtH, such as Woking flyover and station improvements, as these also have a benefit for main line services to Waterloo;
Engage with scheme promoters to undertake further development of
SRAtH options – this would include testing and assessment of the options
identified in our conclusions on a consistent basis to determine the optimum infrastructure and service combination for Surrey. This may require Surrey and its stakeholders commissioning this work themselves. The work should focus on including:
an assessment of infrastructure (Staines link vs longer viaduct/tunnel
link) and service options (fast vs semi-fast services and requirements for stops in Surrey) on a consistent basis. This needs to include a ‘with third runway’ scenario for Heathrow;
a detailed feasibility study of the potential to close/replace the Egham area
level crossings;
consideration of operational impacts on existing non-airport services (with current and future (new SW franchise) service patterns;
the potential service offer for Heathrow services, for example the fares
strategy and rolling stock configuration; and
impacts from and on other Heathrow schemes, for example Western Rail Access from Reading and Crossrail.
The SRAtH scheme should be supported by Surrey and its stakeholders, and with
engagement in further development of the scheme as outlined above, it has the
potential to provide significant and wide ranging economic benefits for the county in future.

Arup Cost Estimates
Surrey County Council Southern Rail Access to Heathrow Final Report
A1 Cost Estimate Assumptions
The cost estimates developed by Arup are indicative and include a number of
assumptions and clarifications. The cost estimates do not consider the feasibility
of construction for each alignment and should be considered relative to each other to provide an indicative cost for each scheme. Details regarding each cost estimate
and the assumptions are outlined in section A2-A6.
Cost estimates based on Arup drawings
Estimates have been undertaken using the Railway Method of Measurement 1 (RMM1)
The estimate uses in-house historic cost data to calculate generic prices
built from basic principles;
Base date of estimate is 1Q 2015;
There are added items, as a percentage of the base construction cost, to arrive at a total construction cost that a Contractor's bid might include. These are:
o Preliminary items at 39%, which includes:
Preliminaries at 25%; assumes concurrent working allowed;
Assumes Overheads and Profit= at 8%;
Contractor's design of 6%;
o Enabling works 3%; traffic management, archaeological surveys, settlement monitoring, environmental mitigation. (Ancillary items);
o A further 2% for environmental mitigation is allowed for works outside the existing rail corridor;
o Site preparation 1%; ground investigations, site clearance. (Ancillary items);
o There is also an allowance for client and Network Rail costs of 12%; this is an accumulation of 8% management, 2% site
supervision, 1% possession management, 1% RIMINI10
. A
further 14% is allowed for TOC schedule 4 costs (compensation for the impact of planned service disruption), And 1% for rail access costs(Network Rail standard for cost estimates);
Primary power is located locally; no major allowances within this estimate;
10
RIMINI is Network Rail’s process for safe working and risk minimisation.

A6 Weybridge Chord Cost Estimate
Due to the potential requirement of re-locating an existing water treatment works Arup have developed two cost estimates, which provide the same functionality in terms of the rail capability but have different alignments.
The first alignment is designed to avoid the water treatment works and lake, however requires a track radii of <200m and special S&C connections limiting line speeds to 10mph.
The second alignment is designed with a larger radii (500m) however it will likely
require the decommissioning of the water treatment works (Arup have allowed £10m for this), and embankment works across the western edge of the lake. The
estimated costs for this option are detailed below (noting the costs are in addition to Option 2).
The following are additional assumptions and exclusions:
No allowance for works to the water treatment works for alignment 1;
Alignment 2 allows £10m for decommission of water treatment works;
Assumed track on embankment - not structure;
No alterations required to the mainline except at tie in to new line.
