Tiles? No exclusive railyards as far as I know.
I did install two copies of the switching yards from the AVAeto citi0 tile into the Combat's tanktown tile. After two years I finally figured out how to make both trains work properly and updated the terrain to have the trains run through the town stations. It's pretty neat if I do say so.
Now then, if you're up for building a new railyard tile, you can find all the track pieces you need here on the boards. Give me a shout if you need help with the excel file to create custom length straight track segments. You will definitely need those unless you build a dead flat tile, which I recommend because of the workload for anything else.
