Southern Pacific Switching Layout

-Extruded foam: my nearest store sells sheets in 2.5 inch, 2x8 sheets for $20 I will need three, but I will have alot left over, total price is $60

Justin;

If the purchasing department can come up with the funds, I'd go with the extruded foam for sure. What little excess you may end up with can always be used for some other purpose. Not sure why you'd have to reduce the length of your layout using the expanded (beaded?) foam, but I'd steer clear of that.

Doing a little test on a piece of the expanded (beaded) foam that I have here, I found that it won't hold track nails very well. At least not as well as the extruded foam does, if you're planning on testing out different track arrangements. And those little white beads seem to pop off of it if you look at it cross-eyed.

Will be looking forward to your new thread when you get all your materials and get started with the layout.
