Toy trains don't have to be an expensive hobby, disposable coffee stirrer are a great source of cheap timber, or possibly free if you have a naughty streak (I'll leave that bit to your imagination, I don't want a global tax avoiding coffee shop knocking on my door).
So, a couple of hours messing about with coffee stirrers, PVA glue and static grass - out pops a rather rustic works halt, all rather Tollesbury Light Railway maybe?
I might add a little fence/barrier along the nearest edge to stop those entering the 2018 Darwin Awards from exiting the train, flying across the rather narrow platform and breaking themselves on the track nearest.
Operationally this will add a little more scope between the coal and timber (pit props with Scandinian pine) workings to and from Fountain Colliery on the next module down. Looking at that train, the brake van would have to have done a lot of work, the engine being steam brake only.
