Thameslink Programme - Objectives

• Reduce overcrowding on

Thameslink and other commuter

services

• Reduce overcrowding to London

Underground.

• Reduce the need for interchange

between main-line and LUL train

services

• Provide for the introduction of

new cross-London services, so

improving public transport

accessibility in South East

Thameslink - Overview

The Thameslink Programme is a government funded initiative to increase capacity on commuter routes into and across London, and to remove key bottlenecks through the re-development of London Bridge station and the introduction of a

new high frequency service through Central London, operated by new 8 and 12-car trains.

• Network infrastructure investment •Signalling, Track, Civils, E&P •Works on 5 Routes

• Rolling stock programme•New Siemens fixed formation trains - 55 x 12-car units and 60 x 8-car units

•Major re-franchising exercise to introduce phased “Thameslink, Southern, Great Northern” franchise•Southeastern largely unaffected

Increasing Capacity - ATO over ETCS Concept

• ATO supervises to achieve journey time using least power, but within

ETCS Protection Curve (EB) – warning curves suppressed.

• Detailed ATO interface/operation specified by the train manufacturer

• Onboard track map

• Event driven interface (packet 44 via RBC)

• Ability to modify dwell/run-time

• ATO brake rate modifiable via packet 44

• Balises used for stopping accuracy at platforms

• +/-0.5m accuracy specified (no Platform Screen Doors)

•IV&V development involves NR, Siemens and GTR

•Initial testing in SI Lab and test track (ENIF)

•NR “2.3.0d” reference train & Thameslink train

•All software/data initially tested in Static Lab

•All dynamic tests first run at ENIF.

•Only uses Core for “sign off” tests or geographical

“tuning”

•Software drops (6 increments) planned in.

• Record as much data from different sources as possible (3

people in a cab will generate at least 4 opinions of what

happened!)

• Onboard (JRU, DMI)

• Infrastructure (RBC, Interlocking, Control, GSMR)

• Every hour of testing generated 4 to 6 hours of analysis

work.

• Maximise testing away from the operational railway.

• Confirm how ‘representative’ of the real world any

simulation is.

• ATO over ETCS is capable of delivering 30tph with careful

system design.
