We finally finished this project up. It is constructed entirely out of MDF. I routed all the edges to try and make it more like wood molding. The control is a DCS Commander remote hooked up to a Z1000 power brick wired to 3 different spots on the track. You can see the IR receiver on the wall. I wired a new electrical outlet with a switch in the closet to hide the wiring. The engine is a Railking SD70ACE from the 30-4219-1 set, which my 5 year old son got for Christmas (thanks JR Junction). He is thrilled, which means I am thrilled.
