Geoff asks:

Where can I get plans of 1960s South Wales Valleys railroads that can be downloaded to P.C? Valley Lines operated rail passenger services around Cardiff and the South Wales Valleys in South Wales, UK. Lines operated consisted of four northern branches to Merthyr Tydfil, Aberdare, Rhymney and Treherbert, which were interworked with the shorter Southerly branches to Barry Island, Penarth, and Cardiff Bay.”
