The project to carry out principal enabling works for the overall scheme was awarded by Network Rail, working on behalf of Transport for London (TfL) and the Department for Transport (DfT).
Currently, four two-car diesel trains run from Gospel Oak to Barking per hour but electrifying the route will enable TfL to introduce new four-car trains from January 2018. It also creates an alternative route for rail freight traffic across north London.
Murphy will work on the track, including track lowering of plain line and switches, and the installation of slab track. Murphy will also reinforce embankments and cuttings, modify signals for 25kV AC electrification and telecommunication assets, and refurbish existing bridge parapets.
Other work includes replacing an existing over-bridge, reconstructing platforms at Walthamstow station and installing foundations for electrification masts along the line.
This is a local job for Murphy, whose head office is just opposite Gospel Oak station. On this contract it is collaborating with project designer Amey and specialist contractor Stobart Rail, which is responsible for the slab track works.
