APPITRACK PROJECTS
Infrastructure - Track Works - Page 8
APPITRACK Modern technology for track laying
Step 1 : Slipformed concrete
Step 2 : Fasteners insertion
Step 3 : Completed slab with fasteners
Step 4 : Completed track
Step 5 : Finished track

APPITRACK - Automatic Pin & Plate Inserter for TRACK
> Accelerates construction => up to 6 times less than the traditional method
> Preserves the environment and reduces carbon emission
> Reduces civil works, concrete volumes and dust> Reduces noise and disturbances> Ensures cost effective & high quality track
construction due to the machine’s high precision> Less painful operations and 3 to 4 times less
accident hazards
Average daily speed in linear meter : 150 lm for tram (maximum 403 lm) 400 lm for metro
> A fully mechanized installation method developped by Alstom

APPITRACK Some project data
> JERUSALEM PROJECT – Completed
> ALGIERS PROJECT – As of 28th February 2011
> REIMS PROJECT – Completed
> CLEO PROJECT – As of 28th February 2011
> Installation program can be more aggressive to increase Appitrack usage

APPITRACK Metro – A new solution
> Tests successfully done in Singapore (length of pumping > 400m)
> Control of concrete consistency test successfully done in Singapore for slipforming
Appitrack (optimised) versus typical project (excluding depot) - 12,2 %
> Optimised planning
> Optimised cross section (less concrete)
> No Stray Current Corrosion Control (to be estimated)
> Comparable perimeter as a new typical project
> Insertion tests done with rebars
> Successful Pumping Tests (> 400 m)
> Development of fastening systems with approved suppliers
> Free for tender in November 2010
> 30 potential projects within 4 years

HAS (High Attenuation Sleeper) : An alternative to floating slab track
Infrastructure - Track Works - Page 13
HAS - High Attenuation Sleeper An alternative to floating slab track
Fastening system according
to customer choice
Concrete sleeper Rigid plastic hull
Holes for conductor rail support
Polyurethane seal
> Use of a rigid hull• Reduction of stiffness (no vertical friction between sleeper and hull)• Friendly maintenance (sleeper easily clipped in the hull)
> Concept of track with sleepers• Friendly construction (standard production rate without discontinuity)• Reduction of tunnels diameter (FST systems being thicker)
> Concept of track with sleepers• Attenuation higher than 20dB at 63Hz
Infrastructure - Track Works - Page 14
Advantages of HAS over FST
> Less concrete (optimisation of the cross section)
> Less manhours required for installation
> Same method than rest of the line
> No stress on the linear planning of works
> Adjustable to specific Rolling stock data
> Friendly Maintenance

HATT : High Attenuation Tram Track
Infrastructure - Track Works - Page 16
HATT – High Attenuation Tram Track
> Preserve neighbourhood comfort• Attenuation over 10 dB• Urban insertion
> Reduce floating slab track quantity• Reduction of more than 25%
of the trackworks costs• Reduction of worksites costs• Reduction of interfaces (Civil
Works, drainage, APS)
> An existing alternative solution• Proven system: already
installed• « proven use » and « proven
design » system type • Trackworks antivibratil
systems installation • Continuous rail support • Less concrete and no tapis
