Report on TSI OPE revision

RISC 69th

Focus of the revision

• Appendix B “Other rules enabling a coherent operation”

• Appendix C “Safety related communication methodology”

• Appendix D “Information to which the RU must have access in connection with the route(s) over which he intends to operate”

• Appendix T “Braking performance”• Train rear end signal for international & domestic

freight trains

Appendix B New: common operational principles and rules

- Methodology was agreed (and presented here with ERA’s intermediate report)

- Comments were taken into account- Start of inventory of existing operating procedures- Risk-based approachGeneral principles in form of operational

requirementsAppendix B – common operational principles and

rules

Appendix BTransfer from Appendix A to

Appendix CNo common basis – postponed to

a future revision

Passing a signal at stop aspect with authorisation

running on sight Written orders running with caution

Failure of level crossing Emergency call Procedure for arrivalComplete failure of front end lights

No authorisation for train movement at the expected time

Speeds in degraded mode

Failure of voice radio communication (including GSM-R)

Departure of a train

Immediate actions to prevent danger to trains

Failure of the audible warning device

Failure/missing rear end signal

Anomalies in lineside signalling

Assistance to a failed train

Appendix C Safety related communications methodology

• Cleaned, clarified and restructured• Predefined messages mostly kept in TSI• Agreed to request a study on communication

methodology with a specific target on the safety benefits of predefined messages

Background: – CER wants to delete predefined messages in the TSI due to

doubts on the benefits– ERA regards them as important, especially for those working in

other than mother tongue– Some IMs have introduced predefined messages and strongly

support them

Appendix D Elements the Infrastructure Manager has to provide to the RU for the Route Book and for the train compatibility over the

route intended for operation

• Before: collection of data elements that are– Necessary for train planning– Part of the RINF– Necessary for train operation– Not relevant at all

• Now: 2 sets of elements relevant for– RU’s preparation of the driver’s route book– RU’s check of train’s compliance with the path

Train rear end signal

- Invitation to clarify/amend operational rules in order to accept plates on all networks when acceptable-Rear end signal for freight trains crossing borders must be accepted for domestic freight trains as well, existing solutions may continue- implicit transition periods with a clear target

Appendix T 4.2.2.6 Braking performance

1st step in 2010/314/EC: – IM defines the required braking performance, RU

defines the rules of train calculation and fulfils IM’s requirement.

•2nd step now: – IM delivers the track side information (gradients;

speeds, stopping distances with safety margins)– RU calculates the required braking performance and

ensures that the train fulfils the requirement– Existing braking tables can be used

In summary

TSIs RST allow for new developments

Capacity needs new developments

RUs are looking for efficiency and safety at the same time

Technology allows new solutions

Restriction to old solutions like existing braking tables

Forcing IMs to follow RST developments for braking performance

Obliging IM to take responsibility for RST-related calculations (required braking performance)

SMS shall support improvements and internal transparency

Recommended revised Appendix T shows a way out for the futureallowing IMs and RUs to agree on a transition period (without limitation)
