... Wales, Barry, Rhymney and the Pontypridd, Caerphilly& Newport. The first challenge has been to discover what type of track they each used. The Rhymney still had a considerable amount of flat bottom rail in use at the grouping according to Kidner, so flat bottom it will be. Photos of Barry track show flat bottom, inside and outside keyed bullhead. So I've decided to go for bull head as Penrhos was a later build. For the PC&N, I've found a couple of photos taken at Treherbert, Groswen and Pontypridd which show outside key bullhead. The next challenge has been to find out about the rail chairs used on bullhead straight heel switches. So far I've turned up a blank. Were the chairs after the heal special chairs? Or just normal chairs squeezed in?
