UK: Infrastructure manager Network Rail has awarded the Signalling Solutions Ltd joint venture of Alstom and Balfour Beatty three contracts totalling £140m for signalling renewals on the Great Western Main Line.

SSL is to design, supply and commission signalling including five Alstom Smartlock 400 interlockings and associated power systems around Oxford, Swindon and Bristol. Completion is planned for December 2015.

In addition to the renewal of life-expired equipment, the projects are being driven by the requirement to prepare for 25 kV 50 Hz electrification and the roll-out of ETCS.
