section of line. County School signal box The original signal boxes at County School were both demolished after passenger closure, but the locking room footings of the main box survived and were restored to allow for the delivery of the original signal cabin from Halesworth to be relocated to the site from Halesworth Middle School, where it had been displayed since 1986. On arrival it was found to be in much worse condition than anticipated, and in 2017, after further deterioration whilst at County School and with no immediate funds available for its restoration, the Mid-Norfolk Railway decided to allow the removal of the signalbox from the brick built locking room and transferred ownership of it to the Mangapps Railway Museum in Essex. Hardingham – Kimberley Park storage capacity Following months of negotiations in early 2018 with local train operating company Greater Anglia, a £3.25M agreement was reached to provide siding capacity for approximately 30 Class 755 multiple units. 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. The Class 755 units will be stored in the sidings during testing, commissioning and driver training prior to being used for passenger services. The scheme included improving the signalling along the line to improve operational flexibility allowing access to the sidings for train movements and for machinery during the construction phase. This include a "No-Signalman Key Token" (NSKT) Electric Key Token system between Wymondham Abbey and Thuxton with intermediate instruments mid-section at the Ballast Pit Sidings and Hardingham. Laying a fan of 5 sidings north of Kimberley Park on the site of an old Ballast Pit to the east of the line at the 4 mile post including a crossover and headshunt. The Up formation south of the accommodation crossing has been dug out of the embankment and levelled to allow the siding closest to the running
