Torpantau railway station is a station in the Welsh county of Brecknockshire (now in Powys), and the northern terminus of the narrow gauge Brecon Mountain Railway. It had previously been a station on the standard gauge line from Merthyr to Brecon, and was the highest station on the Brecon and Merthyr Railway. The standard gauge and narrow gauge stations are in the same broad location, but on different specific sites, on opposite sides of the Torpantau to Abercynafon road.
