I’m thinking of making a layout based on the NCB’s Bickershaw colliery in Manchester, due to having a mix of Hunslet 0-6-0s & Class 20s hauling HAA wagons, and overall looking pretty interesting; although with it being a private industrial railway it is quite hard to find a plan of the layout which the Hunslets traversed. Rail Map online has a bit of a map but I’m not sure if it accurately portrays the yard as it was 1975-1983 or around there. Does anyone have a plan of the complex?
