Thank you everyone for giving Rubin some ideas about the engines with the Pullmor motors.
Dave, I started cutting and gluing a few pieces of Styrofoam to make a scenery base for this area. It will be removable to get at wires.
It isn't far enough along, so I won't bother with a photograph. I'm going to go around the layout and make bases. I have some extruded Styrofoam and thin plywood to make the removable bases. I have been storing a bunch of this white insulation cut to put between studs on 16" centers that my wife brought home from a thrift store a few years ago. It's basically white beadboard. I don't like working with it, but she will be happy when I put some of it to use. I'll cover it over, so it really doesn't matter what it is. It just makes a mess, as does all Styrofoam so what's it matter.
