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.
|
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.

|
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.
|
|
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.

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.

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.

|
|
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.
