VolkerRail has signed a contract with Thales, the global technology leader working in partnership with Transport for London (TfL) to deliver the Four Lines Modernisation (4LM) programme. VolkerRail will install a modern signalling system across 40% of the London Underground network, which carries 1.3 million passengers each day.
Part of its capital investment programme, TfL is upgrading the Circle, District, Hammersmith & City and Metropolitan lines, with new signalling, trains, power systems and station upgrades. The new signalling system will allow trains to be run closer together, meaning a more frequent service and shorter waiting times; allowing more people to be carried. This new technology will also mean reduced delays and improved reliability. The programme will allow the operation of 32 trains per hour, an average 33% increase in peak-hour capacity across all four lines.
VolkerRail will install and test signalling equipment, including copper and fibre cable, from Kings Cross to Monument on the District and Circle lines and from Aldgate East to Upminster on the Hammersmith and City and District lines.
