I built an indoor set for G scale trains. G means garden and its the biggest scale that is made to go outside. I thought it would be cool to put it inside. It fits nice in my basement and measures 17x14. All this stuff was bought new in the 1990s and most has never been open. Two different eras, diesel electric and industrial cars and steam era with box and flat cars. Great graffics like harley davidson, gas and oil, Pepsi, Indian mc, bsa mc, etc. I have alot of extra track, switches, lights, controls and parts. Buildings are assembled and include.. water tower, fire tower, covered bridge, engine house, two tunnel portals and a 4 ft long steel bridge. All brass track and the quality of all of it is excellent. The whole thing is modular and comes apart and could easily be transported. Willing to include if you want or build your own set indoor or out. Everything here to build a complete layout and be up and running.
