1 East West Rail - Digital Railway Challenge

2 Agenda Project description Previous consideration of ETCS Known challenges New study into ETCS - approach Summary

3 East West Rail The big picture Western Section subject of this presentation Central Section Eastern Section existing network on which new passenger services already introduced in the last 15 years

4 EWR Historic Route The Varsity Line

5 High level specification Double track 100mph ruling line speed Route upgraded to provide all gauges up to W12 largest freight gauge in use in UK Route Availability RA10 capable of carry the heaviest freight trains Capacity for specified passenger train service Capacity for one freight train per hour A new staffed station at Winslow New high level platforms at Bletchley linked to the existing station A new platform face at Aylesbury Vale Parkway Platform extensions at Woburn Sands and Ridgmont Passive provision for future electrification Level crossings closed on rebuilt sections and selected crossings closed between Bedford & Bletchley on the basis of change in risk 5

6 Mothballed/ Under-used Railway

7 Mainline new build

8 Project By Numbers c 1.1Bn km 4 11 new 1e 6 cu/m ex km 60 3km

9 ETCS deployment consideration Project proposed ETCS deployment starting in late 2014 rejected at Industry Plan Group Decision restated at joint HS2/EWR Programme Board in early 2017 Agreed scope arising from SoS Challenge to reduce cost, duration & risk of project (summer 2017) based on conventional signalling GRIP 4 design complete for conventional signalling Remit from EWR Co in March 18 to re-consider underlay options Report concluded that underlay was not the answer but that if industry constraints preventing ETCS deployment could be unlocked, there could be a cost saving New remit to consider ETCS only on new build with overlay between Oxford & Bicester

10 New Study Remit Vision In support of regional DR roll out, EWR trains should complete their entire journey in ETCS (excl. Bedford lines)

11 Project Challenges Budget: Pressure has been on the project team to contain the overall cost of the project Time: Great urgency from EWR Co, DfT & Consortium for railway open to achieve project goal of unlocking economic growth across the region Freight operations and HS2

12 Study Challenges Route Boundary Ops & Maintenance changes / control centres Existing Interlockings support for RBC communications Existing interlocking constrains supply options

13 Study Challenges Fit into complex construction programme Short periods for site installation, testing & driver training Conventional signalling based on hangering + plug & play 51 stages with operational change 7 major stages of signalling alteration / commissioning 3 stages with Interoperability Authorisation

14 Approach to study High level scheme sketch to ETCS reference design Test feasibility of ETCS deployment on Core & optional ETCS deployment Defined ETCS options Consider how ETCS could be implemented based on technical baseline Understand operational and maintenance impacts of deployment Review strategic fit with EWR goals Develop implementation programme art of the possible Estimate cost of deployment Prepare report & assure outputs Issue, present & plan next steps Supply Chain Stakeholders EWR Alliance Digital Railway

15 FEASIBILITY STUDY System architecture/ technical solution development Startup workshop + Initial constraints High Level Scheme Design (Core Option) Optional Areas Scheme Design (If required) Implementation Programme Workshop Review strategic fit proposal with EWR goals Plan for next steps Instruction to proceed Prepare Report Assure Report Issue Report Collate findings Optional area feasibility workshops E2 Oxford area E3 Aylesbury area E4 West Coast area Operations & Maintenance Impacts Workshop Cost Estimating EWR Co Involvement Present Optional Area feasibility findings and agree next steps EWR COMPANY INVOLVEMENT

16 Summary Messages Objective is to deliver infrastructure to support economic growth as soon as possible active DR provision needs to show a business benefit Project is very large scale with many stakeholder & inter project dependencies logistics, not complexity is the current challenge HS2 construction constraints enforce complex stage works and approvals EWR- pressure to enter into service ASAP Challenge now to understand how would ETCS change delivery risk profile - how can supply chain help? This is the reality of Enhancement Projects DR deployment needs to be able to support these types of project.
