Following the
Railways Act 1921 Newmarket station was operated by the
London and North Eastern Railway from 1 January 1923. After nationalisation in 1948 the station was operated by the
Eastern Region of British Railways from 1 January 1948. British Railways demolished the buildings on the up platform and a number on the down side in September 1965. Although general goods traffic ceased in 1969 there was a grain terminal operated by the firm Dower Wood located north east of the station that received traffic until summer 1991. The station buildings at the "New Station" were sold, and the current station uses the east end of the down platform and is equipped with basic passenger shelters. Further line rationalisation took place in 1978 when on 1 October
tokenless block working was introduced between Newmarket and Dullingham stations. Five years later in May 1983 the line between Dullingham and Coldham Lane Junction was singled leaving a passing loop at Dullingham. In April 1994,
Railtrack became responsible for the maintenance of the infrastructure. Railtrack was succeeded by
Network Rail in 2002. ==Passenger services==
