I've got a whole bunch of Peco Code 80 turnouts that I've never powered, because you can flick them and the integral spring holds them in place. I'm looking at doing a large "L" shaped layout in a spare bedroom and will have some turnouts that are difficult to reach. Peco sells the PL-10E "extended pin" point motor, which would work if I go with jigsaw/router plywood-on-different-levels construction. But I'd really rather go with a flat tabletop and pink foam wedding cake sculpted with a hot wire cutter. How do I power the turnout from underneath when it's sitting on 3-5 inches of foam plus plywood?
