4

Capacity growth (forecast)

– more passenger journeys

– more trains, longer trains

Capability improvements

– Infrastructure i.e. new lines, platform extensions, signalling, grade

separations, high performance kit etc.

Economic regeneration

– Ashford, DLR and London Over Ground are good examples

Improve asset age (regulatory objective)

– Major works, Reading, London Br, Kings Cross, Blackfriars

What are the drivers

5

Mandate

“To work with the Rail Industry and seek opportunities to

enhance the Rail Network”

Route Utilisation Strategy (RUS)

• Many RUS documents published – L&SE, Freight etc.

• 6 to 30 year vision for the railway

• Published by NR on behalf of industry stakeholders

• Wide consultation – ORR, DfT, TfL, TOC’s etc

• Debates the trade-off between Capacity & Capability

• Economic appraisal has a major contribution to approval of a scheme

6

Recent L&SE RUS Schemes

• Thames Link Programme to GRIP 2 (GRIP explained later)

• Crossrail (1)

• NLL (2012 railway) up to GRIP 3 + London Over Ground Improvements

• Reading up to GRIP 3

• Terminal 5 to Western link (now in early design phase)

• Cross Rail 2 (Wimbledon to Esher – with DfT / ORR)

• West Anglia Capacity (could be part of CR2 to Stanstead – with DfT)

• BML Capacity (could be CR3 Gatwick or East Croydon to Clapham)

• Waterloo approaches (Wimbledon to Waterloo)

• GE Capacity (post CR1 2018) - Liverpool St, Wickford and Chelmsford

• Air Track (Terminal 5 to W’Loo) – suspended by BAA (Airport study)

• Gospel Oak to Barking – Electrification and platform work

Project Governance - GRIP “Project Life-Cycle”

Governance for Railway Investment Projects (GRIP)

There are Eight GRIP Stages

A RUS scheme is outside of Project Governance

and is between 5 to 7 years prior to GRIP 1 Pre-GRIP

9

Developing an RSU Scheme

Requirements not specific (More output driven)

The economic appraisal will show a positive business case

The scheme would have passed the initial scrutiny of ORR / DfT

Existing Train Operators, Local Authorities etc. would have been consulted

The train “Time-Table” is in a early development stage (critical point)

10

Pre GRIP – SE Considerations

Client output (Trains per hr, Journey time, New train etc.)

Can the timetable work – Development TT with many iterations

Can it be built – Railway physics (scheme design)

Asset Configuration – Track, Signals, Electrification, Civils, Comms etc

– Linkage between liner and point assets

Interface management - Assets, Trains, etc into a whole system

Specify the requirement - primary / secondary and linkages

Consider the work breakdown structure (design and construction)

What will it cost?

11

Pre GRIP - Developing a RUS Scheme

Will the scheme fit in within the laws of railway physics

(speed, gradients, curves, breaking etc.)

Active / passive provision for future

New technology / innovation – asset policies, technical strategy

Statutory services (Gas, Water, Electricity, Comms etc.)

Local authority interface

Statutory powers (TWA, planning etc.)

Asset condition

Planned asset renewals

Can it be constructed

Construction phasing in a operational railway

Can it be maintained – safety of staff and compliance

Why this approach

Applying lessons learnt from West Coast Route Modernisation Programme

• Define the output

• Test and Validate output deliverability - cost benefit, future proofing, Timetable

• Apply whole system approach – People, Process, System

• Get the System right at the front end of development cycle before

commencing design phase
