Reopening the railway line between Wisbech and March to enable two trains per hour has been priced at £200.4m at 2019 prices in a report to the Transport committee for the Cambridgeshire and Peterborough Combined Authority. This includes 20% optimism bias but does not include land acquisition prices.
Consultants are currently working on GRIP 3B, which is expected to lead to a full business case that should be published in June.
The current plans would see a railway station located south of the Purina site near the centre of Wisbech. The line would be single track with a passing loop at Coldham and a restored platform 3 at March. The railway service would be two trains per hour on the branch with one train extended to Cambridge subject to the availability of paths.
