Powdermills
00, British Rail (Western), 8 by 3.5 feet
Powdermills was a gunpowder works built in the middle of nowhere for safety reasons. It's now a pottery, cafe, and pony centre. I've assumed it remained active and was connected to the railway by a narrow gauge tramway like Fernilee Powder Mill[1]. Vans bring in chemical precursors and explosives leave in vans. Passenger are workers at the mill and tourists possibly touring the mill. [1] http://goyt-valley.org.uk/fernilee-powder-mill/
