Merthyr Vale railway station is a railway station serving the villages of Merthyr Vale and Aberfan in Merthyr Tydfil, Wales. It is located on the Merthyr branch of the Merthyr Line. Passenger services are provided by Arriva Trains Wales. Since 2008 the station has had a passing loop installed. This allowed a half-hourly service to be introduced on the branch from the May 2009 timetable change. Previously (up until 1991) a loop had existed at Black Lion Crossing, a short distance to the south, which also controlled the siding connections into Merthyr Vale Colliery.
