1 ETCS on East Coast Main Line David MacLennan & Graeme Boyd 1

2 Introduction Why Growing Pains? Is ETCS mature? Does GSM-R meet the requirements for ETCS? Cambrian lessons learned, but not like for like we had nothing to measure against No rule sets, no reference design, immature team, modelling simulating requirements not understood, no NR standards, rule books did not define ERTMS It s a Development Project 2

3 3 ERTMS

4 ECML ETCS Project Complex or Complicated? 4

5 Why ERTMS on the ECML? Driven by the Conventional Interoperable Directive (2001/16/EC) TENS route Control, Command Signalling TSI provision of ATP Signalling life expired To meet 2020 timetable requirements ETCS is enabling the Digital Railway strategy

6 What is ERTMS? European Train Control System (ETCS). Euroradio (Railwayspecific GSM: GSM- R). ERTMS European Traffic Management Layer (ETML). European Operating Rules (EOR). 6

13 What is GRIP 1-3 for an ETCS project? What are the survey requirements? Where are the system boundaries? What does AIP look like? What standards do we follow? Who is dealing with that?

14 National Operating Strategy The Centralisation of Signalling Deployment of Traffic Management (enable ERTMS) Operational savings Improved headways De-conflicts train movements in advance Improved train performance Delays reduced 14

18 18 ETCS Test & Commission Strategy

19 Testing T and C Strategy Factory and Lab Testing (off site) Application Data Preparation, Verification and Validation (Reflects the EFD and ORS requirements, tested via trackside simulation) Functionality Testing (lab/factory via a simulator rig) Static and Systems Integration Testing (proving that the new system can interface with external systems/equipment) Whole System Test Integrating testing with onboard equipment for all Train and Freight Operators (Test track, test facility or third party test house) GSM-R testing Trackside Installation testing interlockings, axle counters etc Static Testing Positioning and checking of balises and marker boards Dynamic Testing on-track confidence testing Functionality Testing RBC handovers, driving without a ETCS MA, transition testing, emergency brake application, start of mission Shadow running 19

24 24 E&P Strategy

25 Why we need an ERTMS E&P Strategy No guidance or standards on what ETCS power requirements are Condition of the lineside distribution current 650 lineside distribution is non-compliant Opportunity to rationalise existing lineside plant infrastructure and to lower asset count Opportunity to take a systematic approach to how we distribute power to our signalling, ETCS and GSM-R assets Reduction in overall load due to the removal of signals Opportunity to increase reliability by taking power from more reliable sources

28 Learning from the Cambrian Understand local procedures- Operations and Maintenance Asset information line speed and gradient profiles, existing infrastructure GSM-R and FTN deployment is it sufficient? Migration strategies Metric or imperial?

29 Whole Life Costs Reduced maintenance requirements Less signallers required Reliability and availability improved via new technologies and improved monitoring More train paths Reduced testing and installation labour costs Reduced delay costs 29

31 Challenges Managing the perception of a GSM-R network Timescales Clarity of overall requirements Limited Radio Resource Pool No absolute consensus on enhanced coverage levels Absence of signalling design Finalised GPRS specifications not yet available Building a case to support the need for an RSV train for programme and ongoing maintenance use Lineside communications post signal removal 31

34 GSM-R EIRENE EIRENE Specification : Minimum value for coverage Coverage probability of 95% based on a coverage level of 41.5 dbmv/m (-95 dbm) on lines with ETCS levels 2/3 for speeds lower than or equal to 220km/h. 34

35 GSM-R So where were we? 35 ECML mainly set up for voice only and CSD Telent reports on coverage were available Design initially started with these, However! RSV is set up for testing voice only and has old equipment (no stopping pattern) No remit from sponsor for ERTMS Telecoms ENIF identified coverage issues even though plots showed ok Interference from MNO s RSV being retired Other ETCS Projects e.g. Thameslink

36 GSM-R - What happened next? National ERTMS Telecoms Steering Group Remit from Sponsor Issues identified Requirement for Guidance Notes required Design route changed NRT/Telent/Kapsch Feedback from other European Administrations sought No new FTN nodes! 36
