2. Agenda What is Crossrail Route Key Features – Connections, Key Dates Current work The signalling challenge Specification Interfaces with other systems Future Challenges Bringing Crossrail into service

3. What is Crossrail New railway under Central London, linking Liverpool Street and Canary Wharf in the east with Paddington in the west. Operates over the wider United Kingdom rail network Required an Act of Parliament to give powers to acquire land and construct the new railway £15.9 billion project budget for construction £2 billion for a new depot at Old Oak Common and a fleet of new trains Complex funding arrangement, with both Transport for London and UK Department for Transport as sponsors Central Government funding Business rate increases Money from third parties

4. Crossrail Route

5. Key Features Major new tunnel connecting Paddington in the west to Stratford and Abbey Wood in the east 10 new stations (all connected to other transport networks) New maintenance depot and train stabling facility at Old Oak Common in West London financed by TfL through a concession arrangement 70 new trains, financed off balance sheet by TfL through a concession arrangement £2.3 billion of works by Network Rail on existing railway funded through a user charge back to TfL for Crossrail services

6. Crossrail – Connecting the Capital

7. Project Key Dates Design and specification 2008 to 2012 Construction 2011 to 2018 Rolling Stock contract – 2014 Appoint operator - Sept 2014 Operator starts services on existing routes - May 2015 New rolling stock delivery commences - 2017 Testing and Commissioning - 2018 Trial Operations - 2018 3 Stage Opening – 2018 to 2019

9. The Crossrail experience

10. Signalling Challenge 24 trains per hour in each direction in the peaks Perturbed capacity of 30 trains per hour in each direction Interface with platform edge doors (PED) as platform dwell times are critical to the successful operation Interface with tunnel ventilation system, Provide outputs to the performance analysis system on train running data Complex and changing interfaces with neighbouring networks

11. Interfaces with Other Rail Systems Pudding Mill Lane Portobello Junction Abbey Wood

12. Interface Requirements Interfaces with Network Rail Infrastructure at Pudding Mill Lane, connection to the Great Eastern Main Line from Liverpool Street Station in the East with a standard Multiple Aspect Signalling (Track Circuit Block) system with UK train protection warning system (TPWS), later full ERTMS level 2, post 2025 Portobello Junction outside Paddington, connection to the Great Western Main Line, interface Multiple Aspect Signalling (Track Circuit Block) with Automatic Train Protection then by 2017 with ERTMS Level 2, initially as an overlay then fully supervised, but with un certain cutover dates Abbey Wood on the South Eastern branch of Crossrail with a proposed non signalled connection for engineering access purposes only.

13. The CBTC Decision Proven technology – where is a system operating today Deliver the train service specification (24 / 30 TPH) Ability to interface with platform screen doors and other operational systems Not be at the technological cutting edge – Crossrail is too large a project to be a test bed

14. Simple Solution? Crossrail is tailor made to a CBTC signalling solution BUT Crossrail is an Interoperable Railway AND CBTC systems are not currently compatible with Technical Standards for Interoperability

15. Derogation Required UK sought a derogation against the Co-Co Sig TSI from the EU for a CBTC installation in the Central Tunnel Section of Crossrail as opposed to looking for an ECTS option from service commencements. Derogation granted in late 2011 with one big caveat. We agreed with the EU as part of the signalling contract, the successful supplier will provide a migration plan to move from the CBTC system to ECTS Level 3 TfL as Infrastructure Manager for the Central Tunnel Section will determine when the changeover will take place.

16. What Does it Mean for Crossrail Allows Crossrail to go with its preferred CBTC option to meet the service introduction date of Dec 2018 Removed the risk associated with being the first to develop a Level 3 solution for a metro application Migration plan will outline the steps and work required to move from CBTC to ETCS L3 Migration will only take place when there is proven technology available, which meets the train and system performance requirements to allow a seamless changeover between the two systems Someone else will have to go first

17. Challenges for the CBTC System Interfaces with other systems – Crossrail is not a closed system like many traditional CBTC applications Interfaces change over time so needs to be adaptable Ability to work with ventilation systems for the tunnel section an additional layer of capacity restriction Future adaptability to ETCS L3 opportunity for CBTC suppliers to develop L3 compatible systems

18. Opening Stages 0 and 1: Dec 2015 – May 2018 Crossrail TOC operating on the Great Eastern: migrate rolling stock from Class 315 to Class 345 in 2017 NR Signalling from Liverpool St IECC. NR Route Control at Romford ROC and CTOC arrangements are yet undetermined GE train service regulated 'as now'. IECC CTOC Control TBD GW Route Control (Swindon) GE Route Control (Romford ROC) RCC Under Fit Out 15 TPH

19. Opening Stage 2 : May 2018 - Dec 2018 Dec 2017 - Crossrail TOC operating on both the GE and GW. Signalled from Liverpool St IECC and Didcot (TVSC) NR Route Control at Romford (GE) and CTOC to be determined. Both railways regulated 'as now'. IECC CTOC Control TBD GW Route Control (Swindon) GE Route Control (Romford ROC) CBTC RCC Supporting T+C Trial Running and Trial Operations CTOC Control TBD 4 TPH 15 TPH

20. Opening Stage 3: Dec 2018 - May 2019 8 months of dynamic testing/trial operations, to commission Crossrail tunnels. Capability for CTOC Route Control (CIS / PA / Security) of Great Eastern and Great Western migrates to Romford RCC. GE, GW and COS all operated as 3 distinct train services, however interfaces with NR routes will be commissioned and operable for movement of ECS. GE and GW railways regulated 'as now'. COS with dedicated timetable / rule set to support the ATR / headway regulation. IECC RCC (Romford) GW Route Control (Swindon) GE Route Control (Romford ROC) CBTC 4 TPH 15 TPH

21. Opening Stage 4: May 2019 - Dec 2019 Through running of GE services to the COS. GW operates discrete service. Effectively run 2 separate traffic flows 12 trains per hour Paddington to Abbey Wood 12 trains per hour Paddington to Shenfield (plus 4 trains per hour between Gidea Park and Liverpool Street) Late running mitigated by decision support software leading to service manipulation in COS or intervention on GE; coordinated from Romford RCC IECC RCC (Romford) GW Route Control (Swindon) GE Route Control (Romford ROC) CBTC 4 TPH 18 TPH 24 TPH

22. Opening Stage 5: Dec 2019 Onwards Full Crossrail service in operation, all interfaces in full operational use. 'Regulation Strategy' will balance 3 inter-related train services. Ability to both present and accept trains right-time at interfaces key. RCC co-ordinates overall service (inc GE for GW) re presentation. Single line at Heathrow and 2 platforms at Abbey Wood create constraints on service patterns. IECC RCC (Romford) GW Route Control (Swindon) GE Route Control (Romford ROC) CBTC 18 TPH 10 TPH 24 TPH

23. Post Commissioning Network Rail will deploy Traffic Management on Great Eastern Main Line Timing 2019 for Liverpool Street IECC Migration. Interface specification to reflect ‘shared data’ for predictive train running algorithms from each side of the interface – a single source of truth.

24. Post Commissioning NR Deploy TM on GW Timing uncertain. Interfaces as per GE GW NR TMSGE NR TMS CBTC RCC Romford Romford ROC Other Region Other Region Didcot TVCS 24 TPH 18 TPH 10 TPH

25. Post Commissioning Crossrail becomes a ‘sub-set’ of wider TM network. Would require an enhanced ‘bespoke’ interface between NR TMS and Crossrail CBTC. Impacts on RfL responsibilities (re regulatory framework) and Operations Concepts (decision making and operational hierarchy). Retain some functionality specific to Crossrail CBTC and wider COS; passenger movement at stations critical and some autonomy is still required. Development and deployment risk is relatively high and outside timescales. GW NR TMSGE NR TMS CBTC Romford ROC Other Region Other Region Didcot TVCS 10 TPH 18 TPH 24 TPH

26. Post Commissioning Crossrail has a commitment to adopt ETCS level 3 (+ATO) when available and risk tolerable. All regulation elements of the CBTC specification would not necessarily be replicated and therefore need to be provided through a second system. The regulation functionality may be provided through an interface with NR TMS, however further work would be required to understand any gaps.
