Notes: The original Newmarket Station was built by the Newmarket & Chesterford Railway Company in 1848. The N & CR was bought up by Eastern Counties Railways in the mid 1850s. The station had a single platform terminus which required reversal when the line was extended northwards to Bury St. Edmunds on 1 April 1854. This extension involved tunnelling under Warren Hill to the north of the 1848 station.

On 21 April 1885 a non-timetabled station called Warren Hill was opened at the north end of Warren Hill Tunnel with the encouragement of the Jockey Club. It had a single island platform located between Bury Road and the Warren Hill signal box. There was a timber booking office at the south the south end of the platform and a covered stairway up to Bury Road. The station was built to cater for the increasing number of passengers arriving from the east and the north on race days particularly Lincoln, Leeds and Manchester. There were three parallel sidings on the north side of the platform and two on the south to accommodate waiting excursion trains. Warren Hill remained in use until at least 1945 but had closed by nationalisation in 1948.

North of Warren Hill station was a triangular junction that allowed trains to run either to Ely or Ipswich. There were also sidings and a coal depot where coal was stored for the Bury St. Edmunds locomotive depot. The platform at Warren Hill was also used for loading coal.
The Newmarket to Ely line closed to all traffic on 13 September 1965 and with it the Snailwell chord of the three-way junction; the track bed can still be clearly seen.
