ok, my space is 4' X 4'. now i can have a 4' X4' bench, or an an L shape or a U shape, just as long as it fits in a 4' X 4' space. i want 2 main lines, one freight and one passanger.( do not have to run side by side) a working yard, a turntable, 2 or 3 industries, mountains with tunnels, and track on top of it, if not a main line then a spur to something. but would like a main to. i want a city with a trolly, even it the trolly just went back anf forth on 3 feet of track, have the ends hidden. do you think it all would fit? or is this too much stuff going on.
