A plan by the Newmarket Railway to link Newmarket with Ely had been authorised in June 1847,[1] but the company got into financial difficulties during 1848 (with no work having been carried out on the Ely line), which led to the partial closure of their existing system in June 1850.
[3] A fourth scheme put forward by the Ely and Newmarket Railway, and supported by the Great Eastern Railway, was successful, being authorised on 11 August 1875 and opening on 1 September 1879.
The ENR did not possess any locomotives or stock and all trains were operated by the Great Eastern Railway.
[4] On 10 April 1888 the Great Eastern Railway (GER) agreed to lease the line for 999 years, backdated to 1 January 1888.
[3] The GER absorbed the line by an Act of Parliament dated 1 July 1898.
