ERTMS will be the worldwide standard for rail signaling for the next decades

ERTMS will be deployed in European core and comprehensive corridors

ERTMS Specifications are stable enough and properly managed by ERA

  • Baseline 2 (2.3.0.d) is an stable version in successful commercial operation in many European and non-European countries (Spain, Italy, Switzerland, The Netherlands, China….)

  • Baseline 3 has been already published into the TSI(3.3.0) and it includes some added functionality (braking curves, crossing level, limited supervision…) as well as bugs debugging.

  • Baseline 2 (2.3.0.d) is an stable version in successful commercial operation in many European and non-European countries (Spain, Italy, Switzerland, The Netherlands, China….)

  • Baseline 3 has been already published into the TSI (3.3.0) and it includes some added functionality (braking curves, crossing level, limited supervision…) as well as bugs debugging.

Mainpendingchallenges: time and money

2

  • Increase market scale

ERTMS costs are too high

Too long process to place in service

  • Increase competition (multiple suppliers)

  • Very high deployment costs (tests on track)

Increase system complexity

  • Operational and train-track integration tests on lab:

  • Reduce time

  • Reduce cost

  • Increase system reliability

  • Advance “last minute problems” (always appeared in the signaling world).

3. How to solve interoperability problems before placing in service a new line?

SYSTEM AUTHORITY AND INTEROPERABILITY (IOP) TESTS

  • Within the new European frame where the operators and infrastructure are separated, it is essential the existence of a System Authority to manage the solution of interoperability problems.

  • MFOM has played this role in the Spanish ERTMS projects.

  • The group led by MFOM (ADIF, RENFE, CEDEX and INECO) has created the validation procedure that allows the opening of railway lines with full warranties of interoperability.

3. How to solve interoperability problems before placing in service a new line?

  • CEDEX Rail Interoperability Lab is the first laboratory in the world accredited for certifying ERTMS components and for testing ERTMS lines.

  • The laboratory was created in 1999. It is has been the pioneer on testing ETCS components and subsystems and it has tested equipment's from almost all ERTMS worldwide suppliers.

  • The laboratory has actively participated in the process of placing in service ERTMS in the Spanish High Speed and Conventional Lines (Madrid commuter lines).

  • The laboratory has designed, together with Adif, Renfe and the Ministry of Fomento, the set of INT tests (around 200 tests) which really guarantee full interoperability.

3. How to solve interoperability problems before placing in service a new line?

Background

  • Components specification, including functional tests specification – Subset-076

  • Tests defined for the whole lifecycle (almost)

On-board subsystem

  • Components specification

  • No functional tests for key components (RBC)

  • ETCS Language too flexible: lack of procedures to validate ETCS trackside implementations

Trackside subsystem


11 th uic ertms conference istanbula 1 3 april 2014

3. How to solve interoperability problems before placing in service a new line?

Possible solutions

  • IN THE MID-LONG TERM:

    • Develop functional test specifications for the (generic) RBC.

    • Develop procedures for verification of the trackside ETCS engineering from the design phase (project specific).

    • Insist on the operational harmonization, keeping in mind the strong relationship among operational rules, ETCS functionality and ETCS language syntax.

  • IN THE SHORT TERM:

    • Bring the final project specific integration/interoperability tests into the laboratory to perform Operational and Train-Track integration tests with real ETCS components (ETCS OBU and/or RBC)

Laboratory Validation

CEDEX ERTMS lab has been previously validated by comparison between the simulated and the real results. This validation it is needed to guarantee a full confidence in the lab results and to assure a correct signaling system behavior during the commercial exploitation.

6. Conclusions.

CONCLUSIONS

  • At the time being, ERTMS reliability and punctuality in Spain is very high, it is really comparable with the mature national systems previously installed in HSL(LZB,TVM).

  • By following the proposed test procedure, the whole ERTMS line functionality is tested in advance.

  • All interoperability problems appeared between the track subsystem supplier and the On board subsystem supplier are previously solved.

  • In all Spanish ERTMS lines, once the integration tests have been successfully completed, not any important interoperability issue has appeared during the commercial exploitation.

    • CEDEX lab has already performed these tests in all Spanish ERTMS lines. It is the European first Reference lab (and therefore the first lab in the world) in this area and it has tested ERTMS equipments from almost all the world suppliers.

    • Before placing in service any new line, integration tests will be also run on track, but these tests will be strongly supported by the integration tests at lab. This is the way of avoiding any “last minute” problems.
