Here’s my decoder testing setup–just on the carpet in my office.
I’m in the process of converting a Piko brewery into a motorcycle factory
The building doesn’t have a loading dock or other provision for getting motorcycles into the boxcars, so the first step was to raise it enough that the floor of the factory came out near railcar height. I accomplished this by building a box and topping it with a scored and painted piece of plastic to represent the wooden dock deck. Then I faced the lower portion with cast stone. There also wasn’t any way to get out the back of the building, so I added a roll-up freight door made ot styrene strips.
