I built the framework and began building my layout in 1996. I started with a 30" deep shelf.



I then put 4" risers on the frame to put the track on.



When I did the wiring I just laid it on top of the frame work,then built scenery over it. This work great for the first 11 years. Then I had a massive stroke in 07. I could no longer reach my wiring. I needed to find an easier way to work on it.

I got some 11/2" PVC pipe. I then split it from end to end and hung it under my layout hatched to the back of the legs. This made a tray to lay my wiring in. I purchased a 25' trailer wire pack attached to power supply block controls. and laid it in the PVC. It is 4 color coded wires, great for my double main line. I don't have photos of the pipe & wire yet but will get it probably tomorrow. Oh yeah the reason I did this is I was developing some power issues and couldn't work on it with it up under the scenery the way it was so I guess it was time to rewire it. This is a lot of work for me and difficult but I had to do something.
I felt I should let everyone know about this so they could could think about it just in case. Especially if they are just starting a layout

Here are the photos of the new wiring. I think you can see the advantage here. I will solder a wire to the rail drop it through a hole to the main wire here. I am going to ad a 12 volt + and -, also a 3 volt for easy access for lights accessory's etc.







Hope this might help someone
