Invensys Rail awarded Glasgow South Suburban resignalling contract

Invensys Rail has been awarded a £35 million contract by Network Rail to deliver the Glasgow South Suburban Resignalling (GSSR) contract.

The GSSR area includes the Cathcart Signal Box area, the East Kilbride branch lines and the Barrhead lines up to the limit of control from the West of Scotland Signalling Centre. As such the area to be resignalled includes both electrified and non-electrified branch and commuter lines.

The scope of Invensys Rail’s contract includes the design, manufacture, installation and testing of the signalling scheme, which will include two new WESTLOCK interlockings interfaced at the West of Scotland Signalling Centre.  Representing 177 signalling equivalent units, the scheme also includes 211 new axle head counter fitments, 88 new location cases, 2 new relocatable equipment buildings and 45 kilometres of new cable route as well as demolition of the Cathcart Signal Box and Busby Junction Relay Room.

As Principal Contractor for the programme, Invensys Rail will also have responsibility for civils, E&P, telecoms, control centre, OLE and -Way subcontractors.

Commenting on the news, Richard Cooper, Invensys Rail’s Delivery Director (North), said: “We’re delighted to have been awarded this contract which will see a new generation of signalling introduced to control the Glasgow south suburban lines.


“The project follows a long period of successful delivery by Invensys Rail on major infrastructure programmes across Scotland, including Glasgow Central Interlocking Renewal, Edinburgh Waverley, Airdrie to Bathgate, Glasgow Central Platforms and Paisley Corridor Improvements.  We’re now looking forward to working closely with our colleagues from Network Rail and the other sub-contractors to deliver another first class project.”

The main signalling installation phase of the GSSR programme is scheduled to begin in March 2012 with works then continuing up to the final commissioning in April 2013.
