I'm in the process of building a new layout, its an around the wall shelf type with a hole-in-the-wall into a 12' x 12' room with the same type of shelf system. I have the base finished and now want to start laying track. Photos of the base can be viewed at http://community.webshots.com/user/chooch261 . I want to use 1" foam board to put the Woodland Scenics roadbed on and I need to know if I can mount the Peco PL10 switch motors under the foam. Should I use Invisamount motor bases and glue them to the foam or is it possible to glue the motors right to the foam. Any help on this or anyone with experience at this type of construction your comments would be greatly appreciated. Thanks, Bob
