London Underground to re-let SSL signalling contract

London Underground (LU) has announced plans to re-let the contract for a major resignalling of the network’s Sub Surface lines (SSL) following discussions with Bombardier Transportation.

Announcing the decision, LU said the decision has been made after considering the “complex nature of the network” and the “nature of the work to be carried out over the next five years”.

Bombardier was awarded a £350 million contract in 2011 to install its CITYFLO 650 system, which is already in use on Metro de Madrid and the Shenzhen Metro, on the network. Substantial preparatory work has already been completed, including the construction of a new unified control centre.

LU has said that Bombardier will continue to supply new S-Stock trains as part of the major improvement programme, which will significantly increase capacity across the Circle, District, Hammersmith & City and Metropolitan lines.

LU’s managing director Mike Brown said: “This is the right decision to make for London Underground and for Londoners. We have been working closely with Bombardier to find a way forward on what is one of the most challenging and complex pieces of work on the Tube. However it has become apparent to both parties that for the work to be completed within or close to the planned deadline, we need to push on with works with another contractor.”

Lutz Bertling, president and chief operating officer of Bombardier Transportation, said: “Together with London Underground we have now laid the foundation for the complex signalling upgrade of the Sub Surface Railway.

“Both parties have jointly and amicably agreed to complete and finalise the works that have been provided to date, and we look forward to working with London Underground as we continue to deliver the new air-conditioned trains for the network.”

LU will this week seek expressions of interest in the Official Journal of the European Union (OJEU) and at this stage there is no change to the original delivery timetable of 2018.
