OK this isn't expressly related to any quarry, but I wonder if anyone has seen a corner of a plan that that involves the early version of Duffws, please?
I know that in Griff Jones' book on Rhiwbach there is a redrawing of the Festiniog and Machno plan of 1853, but there isn't a huge amount of detail.
I now know what the original station building looked like but no idea of the track layout, apart from Boyd. Any pointers gratefully received: as some of you may have guessed it's part of the rolling research into FR signalling.
