This is so cool! I, too, remember the Model Railroader article about the fellow who did the real F-7 nose in his basement and the replica car along side. In fact that was some of the inspiration I had when we designed our present house. The train room is in the basement and I wanted to do an "authentic" railroad bathroom. So, I bought real bathroom artifacts to use. Other than the toilet, everything in it is "real" (Some "friends" did suggest I dig a pit under the toilet and use a real railroad one. But then I would have had to use a sound recording of the wheels on the track that you could hear when using them in the "old days".)
Actually the only part that didn't work was the sink's faucet. Turns out that the water pressure in a pullman is only from the water tank and my plumber could not work out a pressure reducer that would keep from blowing out the faucet's gasket. So, I had to substitute a contemporary faucet. The other issue with the sink is that the drain is hinged backward from normal sinks, so you have to push the plunger down to drain it. Most people do not figure that out even though I put a sign on the mirror to that effect. BTW, the towel rack is a hand rail and the towels are authentic Pullman's.
Then in the train room itself, I've added a few more artifacts. Here is a bedroom light, with the switch for the night/day lights. I love the blue night light's glow.
Here is one of two sets of Adlake repro caboose lamps that I use for reading lights. And below is another Adlake repro marker lantern.
Anybody else using real artifacts in their train rooms?
