The Norfolk Orbital Railway – as the Holt, Melton Constable and Fakenham Railway Company – is a proposed rail project in Norfolk, England, which is proposed to look at bringing a new rail connection to North and Mid Norfolk.

The Norfolk Railway was an early railway company that controlled a network of 94 miles around Norwich, England. It was formed in 1845 by the amalgamation of the Yarmouth and Norwich Railway opened in 1844, and the Norwich and Brandon Railway, not yet opened. These lines were built out of frustration that the Eastern Counties Railway line that was expected to connect Norwich to London failed to be completed. The Norfolk Railway also leased the Lowestoft Railway and Harbour company, and built a branch to Dereham and Fakenham, opened in 1846 and 1849 respectively.
