The facility on Bombardier’s Litchurch Lane site will measure 250m by 40m enabling it to handle four ten-carriage trains.
The work includes the construction of four multi-functional train lines, each with full length overhead lines and inspection pits containing a full range of services that will be fully accessible by rail at both ends, connecting into the existing test track facilities.
The project will create office space in the form of a two-storey annex, along with associated power upgrade works to the site to facilitate the overhead electricity lines.
Peter Commins, Balfour Beatty managing director for the North West, said the project will be completed by winter 2016.
