Bombardier to modernize London Underground signaling

Bombardier Transportation and London Underground (LU) announced the signaling contract for the Circle, District, Hammersmith & City, and Metropolitan lines (sub-surface lines) will be re-let by LU following discussions between the two companies.

Bombardier was awarded a contract in June 2011 following a competitive tender process and has already undertaken a great deal of preparatory works.

The new contract will see signaling modernized on 40% of the Underground network, allowing LU to run more trains, more often and more reliably.

Combined with 191 S-Stock trains, which Bombardier has successfully supplied for the Metropolitan line and which are now being introduced on the Hammersmith & City and Circle lines, the upgrade will increase capacity on the sub-surface lines — the Circle and Hammersmith & City lines by 65%, the District line by 24%t and the Metropolitan line by 27%.
