DB, To answer the question in your post. I did look into converting two rail DC locomotives into three rail. I gave up after deciding that the easiest conversion would be to put a diode bridge in the tender to get dc for the two rail loco. There were other issues that stopped me. Marklin 3 rail uses the NEM standards for their wheel sets and for the size and spacing of points, guard rails and frogs in their switches. These are slightly different than NMRA Rp 25 standards and the resulting mis-matches show up when you run through a switch on the diverging route from the frog end. The NMRA standards cars derail (I fixed this by shimming certain stuff, but it was a hassle and I was never completely satisfied). I was able to get Athearn and Proto 2000 cars (especially tank cars) to run through the 2271 wide radius moveable frog swtiches. I had cars with a Kadee on one end and a Marklin coupler on the other that I would hook up to Marklin locos and pull a string of Intermountain reefers around the layout. (E-mail me off forum if you want more info) I eventually quit torturing equipment and started a new layout with US prototype gear in two rail. BTW: There is a guy on Ebay selling converted 2 rail locos for Marklin 3 rail. I saw a Spectrum Shay for sale as a three rail conversion. you might email him and ask how he solved these issues. Or buy some of his conversions. Here is a link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1557&item=5960683198&rd=1
