What do you think of this 3x6 track plan?

[RobertInOntario]

OK, I've just gotten back to this layout and am tinkering with it again. At the moment, I'm using the original 3x4 board and have two loops of track. The outer loop is made up of 18"R and 15"R curves while the inner loop has only 15"R curves, with two sidings. I'm going to continue to experiment with it and see what I come up with over the next few weeks. Rob
