Looks like I'll have plywood boards (not just a loop of custom-cut roadbed) under the pool table, yes- lifting the legs up just enough one at a time for the loop around the pool table. thortrains has lots of fun track plans!-I think my area is closer in size to a 5x9 than a 4x8. But no matter; I can scenic it, add more track, including switches, and even put down buildings, etc. YIPPEE!!!
