"Approaching Tonypandy from Treherbert, on a DMU 1962." View southward, towards Tonypandy (& Trealaw - until 5/73) down the Rhondda Fawr valley from Treherbert, on a DMU for Cardiff via Abercynon and Pontypridd. The DMUs had then only recently taken over from the Steam 0-6-2Ts on the local passenger services and were welcome to Train-Spotters for the view ahead you might share with the driver. Moreover, many of the coal-mines were still active and the coal traffic remained intensive - and worked by Steam locomotives for a few more years.
