This is the only way to work on under the layout wiring. Turn the layout on it's side and sit on a roll around stool. Which was good because my knees are really bothering me. I had to finish up a rewire and add the DCS TIU. Of course this is not practical for most people's layouts. I built this one to be folded up into a 4' x 8' x 16" (aprox) box on casters. This was so I would have access if I need the garage for something, also to move the layout. It does not have now, but will have, a top which will be split in such as to make a 2' tall backdrop for two sides of the layout. The track is on 4' x 8' and when folded out makes a 6' x 10'. I can't do much of the laying on your back and working overhead anymore.
