The Wymondham to Wells Branch was a railway built in stages by the Norfolk Railway, Eastern Counties Railway and Wells and Fakenham Company between 1847 and 1857. The railway ran from Wymondham in the south, through Dereham and Fakenham to the coastal town of Wells-next-the-Sea; more specifically, the line ran from Wymondham South Junction, where it met the present-day Breckland Line. Passenger services along the line lasted until 1969; the railway continued to be used for freight until 1989. The southern section of the railway now forms the Mid-Norfolk Railway, with part of the northern section serving as the narrow gauge Wells and Walsingham Light Railway.
