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.
