I guess the obvious answer is buy some but let me tell you what I actually mean. I had planned to build in N Scale but decided against that because of what seems like a higher cost in rails and such and the fact that it's harder to find an engine that will accept decoders(especially steam). Anyways, I've decided that I may go with HO but the type of layout I want requires larger then 8x4 by a few feet and I don't have any tools here and don't want to start spending on tools to build and cut wood.(No saws). The whole point is without the wood I have to find another way. I had thought of laying the track on the ground. You should be aware that my setup is only for 8 months until I have to dismantle so I wasn't planning on scenery or anything along this train of thought(Pun Intended). The idea was to just lay track and enjoy controlling the trains doing some switching and hauls. Is it possible to lay track ontop of carpet and using the small nails just to hold the track in place or is this an absolutely stupid idea? Also will the carpet cause shorts?(I know static electricity is caused by rubbing with carpets and I don't know the conductivity of carpets myself. Any thoughts would be appreciated. Maybe sticking to N would be better and having to deal with having only the Decoder type trains. I'd like to hear your opinions.
