Greater Anglia require a significant increase in siding capacity while they introduce their new fleet of trains as both the old and new fleets will be in East Anglia at the same time. The agreement was announced to the members of the MNRPT at the Trust's AGM on 30 June 2018 with work commencing on site three weeks later. Construction of the sidings is being paid for from upfront storage charges paid by Greater Anglia. As the principal contractor is Sonic Rail Services of Burnham-on-Crouch, the project has been nicknamed "Project Hedgehog" by some of the MNR's volunteers in honour of Sonic the Hedgehog.
