You can get those prefab outdoor sheds for a back yard that are assembled on site. Install any plumbing or electrical and then go ahead and drywall it your self, or use tongue and groove plywood panels for the inside walls. The advantage of plywood on inside walls of a train room is that you can secure benchwork to the walls with screws anywhere you want to instead of needing to find the studs like you do with drywall. Before I retired from Carrier-Transicold, they set up a service agreement with Sysco Food Service to maintain their City of Industry refrigerated fleet. Sysco has over 500 refrigerated trailers at the City of Industry location, so we had a full time mechanic assigned to the Sysco location. We got one of those sheds 10 feet wide by 20 or 30 feet long to house an office, and parts room. It was wired for electrical service and compressed air. Those sheds are probably among the least expensive type of construction that you can get, and they look a lot nicer than the cheap sheet metal diy sheds.
