Stan ,
I do plan to build this, I don't have DCS, but I would likely run it on both Legacy at 18v and if possible on conventional/ variable voltage. I would probably use a slide switch mounted on the chassis to disconnect power from the track and be able to operate silently if need be. I understand the EBAY addiction, I spend more time there than I should. I do appreciate any help you can give me for aquiring the proper materials.
