I'm new to the hobbie, and need some help. I've got an o/o-27 scale train, and would like to run it around the TOP of my son's room, on an elevated track that is attatched to the wall (about 20" below the ceiling). I cant find any helpful info on how to biuld, specs, etc. I've seen this done at a local restaurant and several pictures in mags, but now that I want to do it for myself I cant find any info. Please help if you can, very much appreciated!!
