Hi Joe, thanks for that, though I think I may have seen that already!
The parts I am now stuck on are the paint color, the thickness of the shelves and how the lights and wiring are done. As far as I can see, the top shelf has a groove on the bottom with the wiring in for the accessories. This is covered in the paper, then painted. I going to make the frame out of 1" x 4", I think that is the same size wood stock that was used for the train table part, but I'm not totally sure.
