Nice to see someone modelling an HF Stephens branch, built for the LSWR to replace a 3' mineral line between Callington and Calstock Quay, via a rope worked incline.
In the early years of the new line, there was a wagon lift, on the RHS of the Calstock viaduct, to maintain access to the Quay.
Julie.
P.S. The livery of the bubble car, is correct for the early diesel period on the line.
