Hoping someone can offer their creativity in helping me design a sufficient trestle system for my elevated track. My benchwork is 2x4s covered with 2 inch pink foamboard (no plywood). I am wanting to create an upper level using o27 (42") track. I can not use the Lionel elevated trestles because they are too wide at the bottom for what I am trying to achieve. I have seen several folks use dowels with a square on top to mount the track, but am unsure how to secure the dowels to the foam board if I go with that method. Open to any and all suggestions. THANKS

For dowels. I would drill a hole in the foam board (1+" deep). Then liberally coat the inside of the hole with wood glue or Elmer's glue. Let the glue sit for 5 minutes. Then insert the dowel The wood glue will seep into the foam. It will harden to create a rigid foundation reinforcing the immediate foam surrounding the dowel.

You'll need a method for drilling perpendicular holes into the foam lest your trestles look crooked.

You could test this on the underside of the foam board.
