ETCS on East Coast Main Line

1

David MacLennan & Graeme Boyd

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

Its a Development Project

ECML ETCS Project

Complex or Complicated?

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

What is ERTMS?

European Train Control System

(ETCS).

Euroradio (Railway-specific GSM: GSM-

R).

European Traffic Management Layer

(ETML).

European Operating Rules (EOR).

What is GRIP 1-3 for an ETCS project?

What does AIP

look like?

What are the

survey

requirements?

Where are the

system

boundaries?

Who is dealing

with that? What standards

do we follow?

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

E&P Strategy

24

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

GRIP 4-5

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?

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

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

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

GSM-R So where were we?

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 MNOs

RSV being retired

Other ETCS Projects e.g. Thameslink

35

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!

41

Capacity

Existing GSM-R Network is Circuit Switched

Most of the BTS on route have only 1 DRX installed

Increase required for data and voice in normal and

perturbed operation

Timetable require 28 trains per hour what does that

mean?
