A station serving this area of the town was first opened at Oxford Street by the Taff Vale Railway in 1888. This was closed to passengers by the Western Region of British Railways in 1964. Passenger services were reinstated to a new station by British Rail in 1988. There is a passing loop situated here (constructed in 2002, when the station was also rebuilt), which allows a half-hourly service to operate and freight trains to operate alongside the passenger service on what is otherwise a single track route.
Monday to Saturday daytimes trains run half-hourly each way, north to Aberdare and south to Pontypridd, Cardiff Queen Street and Cardiff Central. They then continue to Barry and Barry Island, though a limited number of peak & late evening services run to Penarth. The frequency drops to hourly in the evening & every two hours each way on Sundays.
