The South Wales Railway between Swansea and Chepstow (later Gloucester) passed through Magor and a station was opened here in the 1850s, shortly after the line opened.
The station provided three sidings serving local farmers.

By the 1920s, traffic on the line was so heavy that refuge sidings were provided on both lines.
In 1941 the main line was doubled to four running lines, with the outer two lines as slow goods-only lines to serve the increasing wartime coal traffic, without delaying fast trains on the central main lines.

The station closed, along with Undy Halt, in November 1964; although the goods yard remained open until 1965 for cement trains connected with the building of the M4 motorway.
