Railway Engineers Forum Scotland Young Railway Professionals’ Presentation Competition Northwich Diversion Gauge Clearance William Storey Graduate Civil Engineer - Babcock

Contents Project background Works overview Delivery plan –Track works –Drainage My role

Project background The Northwich Diversion route was cleared to W8 gauge to enable freight traffic to be diverted allowing for access on the Liverpool to Manchester line to carry out electrification works. This involved 5 track lowers at 4 bridges.

Project contracts GRIP 3-8 –NR4 for GRIP 3-5 –NR9 for GRIP 6-8 Project came off the back of Liverpool to Manchester (phase 1) which was a number of track lowers on the line being electrified Contract value –Northwich Diversion circa £600k –Total value of Liverpool to Manchester and Northwich Diversion circa £1million Project awarded 17 weeks before 1 st core possession The work was delivered in November 2011
