On my Weaver Junction switching layout, I'm using Caboose throws to activate the switches. Right now they're glued directly to the foam, but I've had several come loose during operations. I've tried white glue and caulk to fasten them down, and surprisingly to me, the white glue has held up better. Still, the white glue will occasionally let go. My next step is to add track nails to help hold them in place, but was wondering if anyone had success with a particular type of adhesive for these. Any and all advice appreciated.
