The Rhondda railway line runs from Pontypridd to Treherbert. Originally built to transport coal to its various markets - much of it for export via the port at Cardiff - the line is now a single track, and isn't used by freight at all. Until 1965 the line contiued on beyond its current terminus, though a tunnel which it entered at Blaencwm and exited at Blaengwynfi, before continuing along the Afan Valley to rejoin the larger lines at Port Talbot.
