The line from Fakenham to Melton Constable was built by the Lynn and Fakenham Railway, later the Midland and Great Northern Joint Railway's main line from Peterborough to Great Yarmouth. The line from Melton Constable to Holt was part of the M&GN branch line to Cromer. The section between County School and Fakenham was part of the Norfolk Railway, later the Great Eastern RailwayWymondham to Wells Branch. The M&GN main line closed to passengers in February 1959. The branch line remained open, operated as part of the line from Norwich Thorpe, when it was cut back to Sheringham in 1964. The passenger service on the GER line from Fakenham ended in 1964, with the line finally closing in the 1980s.
Route
The route is planned to run from Sheringham to Dereham via Holt and Fakenham. In January 2019, Campaign for Better Transport released a report listing the line as Priority 2 for reopening, with Priority 2 being described as "feasible projects which require further development or changed circumstances to assist them in being taken forward". The route south from Fakenham, forming part of this scheme, is protected by North Norfolk District Council from any development that would be prejudicial to the restoration of a railway line
After 36 years the Bittern line was reconnected to the North Norfolk Railway via an "occasional use" link between the Network Rail station and the North Norfolk Railway's tracks. Although the length of the link is only a few yards the agreement represents a step towards a permanent link and new interchange station. This link is initially available for occasional use and for delivery of rolling stock. The crossing was opened on 11 March 2010, after two months of work.
The Holt link
The first section of the formation to be purchased by the Norfolk Orbital Railway is located between the North Norfolk Railway's Holt station site and the town bypass, which was built on the railway formation. The NOR plans would see a line relaid on the wide verge beside the road. The company paid £25,000 for the 50-yard stretch of former track bed, and erected a small sign on a tree to indicate that it is now back in railway ownership. The section of formation was cleared of vegetation in 2016
In 2009 the Norfolk Orbital Railway attempted to secure a section of the railway formation in Fakenham, but was outbid by a London developer who claimed not to know of the project. The land was once again auctioned on 10 December 2014, and was secured for the railway project for £24,000. In 2016 the project was awarded £60,000 from the Heritage Lottery Fund to help repair the Fakenham bridges, provide an education resource, equipment for the Fakenham Area Conservation Team and to create a walk along the preserved formation for people to enjoy. The walkway is currently maintained by the conservation team, but has also suffered from the attention of local vandals. In August 2019 the Lottery-funded restoration of the formation was completed, with local councillors and land-owners invited to a meeting at County School railway station, followed by a tour of the restored formation footpath.
