Since I don't have the space yet, I decided to set up a little 4'x2' piece of plywood and throw some track on it so I can run my engines. I got to say, I'm so glad I run N-Scale and not anything bigger. It's a double oval with a basic switch-over and two tiny spurs. But it's enough that I can run two engines pulling 4-5 cars simultaniously. I like it so much, that I may just build off of the basic design when I finally buy a house and get a big chunk of the basement to work with.
