During a 10 day blockade at Liverpool Street Station, the 120 year old dilapidated structure was demolished to make way for a new bridge capable of carrying the new generation of rolling stock that will operate on the East London Line, due to open in 2010. GE19 had been out of use for decades and its demolition involved the disposal of 12,000 tonnes of brickwork.

This project forms part of the Transport for London £1.4bn investment in the creation of the London Overground network.

Colas Rail was contracted to support the signalling aspects of the bridge demolition which included the re-location of existing signals.

Despite the fact that the signalling works were undertaken during a busy blockade that saw significant infrastructure renewal across a number of asset groups, the works were completed on time and to the clients satisfaction.
