The Quakers Yard and Merthyr Railway was a railway company in South Wales. It was owned jointly by the Great Western Railway and the Rhymney Railway.[1]
At its southern end, the line connected to the Vale of Neath line of the Great Western Railway (GWR)[1] at Joint Line Junction, just west of Quakers Yard High Level railway station.[2] The line ran up the Vale of Merthyr, and at the northern end it connected to the Merthyr branch of the Vale of Neath line at Cyfartha Junction.[1]
The line was jointly owned and operated by the GWR and the Rhymney Railway; it opened in 1886.[1]
Passenger trains over the line ran between Merthyr Tydfil and Cardiff; the services ended in 1951.[1]
