Well, Ray, I looked up the North Gower branch in my Forgotten Railways of South Wales book by James Page, and it seems I was mistaken. I'd supposed that the branch ended at Penclawdd. It didn't, and went on to Llanmorlais (the village.) It was built by the London and North Western Railway; I had described to you the way that the branch connected to the Great Western main line at Gowerton Station - it didn't, and remained separate from the GWR main line until it connected to the Central Wales line (which was owned by the LNWR) at Gowerton South station.

Page does not say what the colliery was called, merely saying the line was "built to serve mineral interests in the area." Describing the branch as "lonely", he says: "The line ran along the edge of windswept saltmarsh for much of its way, through scenery reminiscent of the north Brittany coast, west of Mont St Michel. It is remembered today for the cockle traffic that originated at Penclawdd, providing the staple traffic of the branch for many years until the advent of the motor lorry. Pessenger services ceased in 1931, freight in 1957."

I think the colliery was called Llanmorlais, but I'm not 100 per cent sure on it. I used to have an invaluable index, published by the Coal Board, which must have had the colliery in it - however, the stroke coupled with two moves played havoc with my South Wales history. Sorry!
