Hi, great to follow your progress. I've sort of stalled with my layout of Mallaig. But thought I'd share these with you - I made my curved platform from 2 layers of XPS insulation board - 10mm and 6mm. They are light and easy to cut to curves, for example. The top layer I cut a chamfered edge to it to try and simulate the platform faces on the West Highland. I actually made these before my first ever visit to Mallaig last year, and maybe could have done better. But they are ok for my standards. I've used bought card pavings for the edge, and I plan to fill the gap for the platform surface with Woodland Scenics snow, which is easy to smooth and level.
The station laps are the closest I could find to the 1970s version, cheap LED models from ebay, painted in appropriate colour.
And the oil depot is a mixture of Knightwing and scratch built. The large tanks are plastic drain pipe, with plasticard top, all painted silver, awaiting weathering. Well, everything on the layout is awaiting something or other!
My plan for the station was to have a removable roof, and retaining wall in 3 sections to represent with roof, without roof, and current day. I may have been a bit optimistic, and that has stalled too!
