Here's a test of the no ballast code. The colors are just so I can see what was actually going on. I need this for my machine shop which has service pits. Normally for things like stations you can leave the ballast and just nudge some rectangles up to the track. Anyhow these are ON30 but presented here for food for thought. Russ
