Brownfield Resignalling / CBTC Experience

1                    Introduction

A summary of Kusieog’s recent experience with Brownfield Signalling Replacement projects and current CBTC systems. For earlier experience of brownfield projects, comprehensive experience and full CVs, see www.kusieog.com.

2                    MTR Corporation Hong Kong – East Rail

Project Scope

Replacement of the Alstom intermittent beacon based TBL ATP system on the intensively used East Rail (EAL) Line with all work during non-traffic hours with no extended possessions.

Due to the mixed traffic nature of the line, the CBTC solution retains signals and AWS for the China Through Trains.

Initially the existing 12-car rolling stock is dual fitted with the TGMT system. After changeover, there will be a gradual migration to new TGMT-only 9-car trains.

Client

MTR Corporation

Contractor

Siemens

Signalling Technology

TGMT CBTC. Initially with train operators but capable of FAO with the new Rotem trains.

Key Strategy

Implementation is based on Direct Changeover (whole system switch-over) with incremental over and back testing during non-traffic hours.

The core technology requires many modifications to accommodate MTR’s operational requirements

Kusieog Role

Initially Kusieog was brought in to look at problems with the existing signalling system through implementation of the new CBTC. This included technical reviews into the old and new signalling, rolling stock interfaces, performance targets, implementation strategies and running of mixed fleets over the new signalling (TGMT).

Subsequently Kusieog was retained as Independent Reviewer (IR) for the EAL CBTC replacement project, focusing on the management of Operational Risk to acceptable levels during the project implementation, testing and commissioning and acceptance. This includes developing methodologies to quantify and manage operational risk, and involves working independently with MTR and the Contractor to facilitate optimum solutions.

Timescale

Kusieog commenced work in 2014 and the initial stage of the project, using dual fitted TGMT trains, is expected to be commissioned in late 2018.

 

 


3                    MTR Corporation Hong Kong – DUAT

Project Scope

Replacement of the existing Alstom SACEM system on the intensively used 7 Urban Lines with all work during non-traffic hours with no extended possessions.

Initially the existing rolling stock is dual fitted with the Thales Seltrac system with gradual introduction of new trains during mixed mode operation.  Following commissioning of new CBTC only trains, the dual fitted trains will migrate to the next line to be resignalled and so on.

Client

MTR Corporation

Contractor

Alstom Thales JV

Signalling Technology

Seltrac CBTC. Initially with train operators but capable of FAO with the new trains.

Key Strategy

Initial implementation on the Tsuen Wan Line is based on Progressive (incremental) Changeover with initial new system testing during non-traffic hours before “shadow mode” operation in off peak service followed by mixed mode operation with progressive changeover of trains to Seltrac working and subsequent migration to new Seltrac-only trains.

Some of the other lines require a Direct Changeover approach.

Kusieog Role

Kusieog was retained as Independent Reviewer (IR) for the project, initially on the Tsuen Wan Line, focusing on the management of Operational Risk to acceptable levels during the project implementation, testing and commissioning and acceptance. This includes developing methodologies to quantify and manage operational risk, and involves working independently with MTR and the Contractor to facilitate optimum solutions.

Timescale

Kusieog commenced work in 2016 and the Tsuen Wan Line is expected to be commissioned in late 2018. Future Lines are implemented over several more years.

 

4                    MTR Corporation Hong Kong – Kwun Tong Line Extension

Project Scope

Two station extension of the existing Kwun Tong Line.

Client

MTR Corporation

Contractor

Alstom

Signalling Technology

Extension of existing Alstom SACEM system

Key Strategy

Greenfield extension of existing system with brownfield interface to existing line

Kusieog Role

Kusieog was retained as Independent Reviewer (IR) six months prior to opening of the extension to facilitate the resolution of some blocking technical issues and to make an overall assessment of operational readiness.

Timescale

The work was undertaken from mid to end of 2016 and the Extension opened on time in 2016.

 


5                    MTR Corporation Hong Kong – South Island Line East

Project Scope

New five station FAO Line

Client

MTR Corporation

Contractor

Alstom

Signalling Technology

Urbalis 400 CBTC system

Key Strategy

The first major FAO Line in Hong Kong.

The technology required many modifications to accommodate MTR’s operational requirements

Kusieog Role

Kusieog was retained as Independent Reviewer (IR) prior to opening of the extension to make an overall assessment of operational readiness

Timescale

The work was undertaken from mid to end of 2016 and the Extension opened on time in December 2016

 

6                    Bangkok Expressway and Metro (BEM) Thailand – Purple Line

Project Scope

New 23km Heavy Metro – PPP Gross Cost Model with 30-year Operations Concession

Client

BMCL, now renamed Bangkok Expressway and Metro (BEM)

Contractor

Marubeni Toshiba JV

Signalling Technology

Bombardier Cityflow 650 CBTC system

Key Strategy

The Government builds the metro civil infrastructure and track and the Concessionaire, BEM, is responsible for the power supply, railway systems and rolling stock.

Kusieog Role

Kusieog prepared the original tender strategy, tender documents and the management of the tender process using an experienced team of up to 24 engineers. Subsequently Kusieog provided the Operations and Technical support core team during the project execution.

The Kusieog team had to manage and resolve many of the systems and interface issues, including the rolling stock / signalling interface.

In respect of the Cityflow 650 implementation, Kusieog provided the key signalling engineering support and managed the resolution of the initial deficiencies directly liaising with Bombardier.

Timescale

Kusieog has been working with BMCL / BEM since 2002 on safety, operations and maintenance continuous improvement.

Purple Line involvement since 2010, with the line opening in mid-2016 after a 30-month programme.

Kusieog is currently providing the Operations and Engineering core team for the extension of the existing Blue Line Metro.
