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 which carries 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 is a two year; £6.2 million project and VolkerRail are to deliver all the rail system elements including design, p-way, OLE, signalling and E&P works. The Project involves the construction of a new single track electrified railway providing a grade separated link, partly on a viaduct structure and partly on embankment, which will allow Cambridge bound trains from London to pass over the top of the East Coast Main Line; this will increase reliability and assist in improving capacity on the East Coast Main Line.
The new junction will be 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 splits into four phases:
The main contract commenced in August 2011, with the first phase being completed March 2012.
