VolkerRail was awarded works under the Hochtief/Network Rail alliance to design build and commission the Hitchin Grade Separation which consists of a new railway line to carry trains from the East Coast Main Line in the down direction over a new 29 span 800m viaduct and 1.2km chalk filled embankment to join the down Cambridge line.
This was a two year; £6.2 million project and VolkerRail delivered all the rail system elements including design, p-way, OLE, signalling and E&P works. The Project involved the construction of a new single track electrified railway providing a grade separated link, partly on a viaduct structure and partly on embankment, which now allows Cambridge bound trains from London to pass over the top of the East Coast Main Line; thus increasing reliability and assisting in improving capacity on the East Coast Main Line.
The new junction is positioned at Hitchin north junction approximately 1.1km North of Hitchin station, to link the down slow and down fast lines of the East Coast Main Line with the Down Cambridge line.
The programme was split into four phases:
The main contract for VolkerRail commenced in August 2011 and was commissioned June 2013, five months ahead of schedule.
