It is on the Cambridge branch of the Ipswich–Ely line and is 800 yards (730 m) south of the site of the original Newmarket station.

The two through platforms, generously provided with canopies, were connected by a subway faced with white-glazed bricks.

On the up side there was a large refreshment room (with floor space of 1,648 feet) with kitchen and cellar as well as stores for footwarmers and lamps.

The station was built by Rugby firm Parnell and Son under GER supervision and was electrically lit throughout.

Further line rationalisation took place in 1978 when on 1 October tokenless block working was introduced between Newmarket and Dullingham stations.
