There are two small car parks, one at street level in front of the station building, the other at platform level to the south of the station.

The platforms are located on an embankment, with access to street level by stairs and a pedestrian underpass.

History
The station is on the original line of the Great Western Railway, which opened on 1 June 1840. The original station, opened with the line and known as Wallingford Road, was several hundred yards further up the main line towards, just east of the point where the A329 road crosses the line. Some of the original station buildings can still be seen at this point. On 2 July 1866 Wallingford Road station was renamed Moulsford and the branch to was opened five days later; whilst the junction for this was at Moulsford station, the branch line track ran parallel to the main line for nearly before curving away. In 1892, during quadrupling of the main line, the junction for Wallingford was resited closer to the point of divergence and a new station was built there. On 29 February 1892 the new station opened and Moulsford station closed. The Wallingford branch closed to passenger trains in 1959 and to freight trains in 1981. Part of it is now preserved as the Cholsey and Wallingford Railway.

Services run every 30 minutes in each direction Monday to Saturday and hourly on Sundays.
