The station is now the terminus of the Maesteg Line from Cardiff via Bridgend.
Previously the line continued northbound through the old Maesteg Castle Street railway station (opened in 1864), which closed with the withdrawal of passenger services in 1970.
Mineral traffic had continued to several collieries in the areas until November 1985 (with the route remaining open past Llynfi North Junction as far north as Nantyffyllon to serve the NCB Maesteg Central Washery as well as the three pits) but the closure of the last remaining mine at St John's and the washery saw the line fall into disuse.

The former station platforms and footbridge still exist, although the track has now been removed and there is heavy tree and plant growth at the location.
