Cwmbach railway station serves the village of Cwmbach in Rhondda Cynon Taf, Wales. It is located on the Merthyr line branch of the Merthyr Line. Passenger services are provided by Transport for Wales.
The first station on this site was a halt opened by the Great Western Railway in 1914. It closed with the line in 1964.
The present station, along with the line to Aberdare, was reopened by British Rail in 1988.
During 2005, construction work was carried out to double the platform length. This now allows four-carriage trains to stop at the station.
There is a half-hourly service in each direction on Mondays to Saturdays: northbound to and southbound to and . This drops to hourly in the evenings.[1]
On Sundays, there is an hourly service between Aberdare and Cardiff Central. The increase in the Sunday service frequency is due to a campaign by the local Assembly Member and a successful trial in December 2017; the extra services began in April 2018.[2]
DB Cargo UK operates coal trains to Tower Colliery, which pass through the station on weekdays and on some Saturdays. Freightliner also operates an irregular stone service to Tower.
