Jim,
I also did one a few years ago. I removed everything and used a Lenz 1.8 amp back-EMF DCC decoder. Worked great despite the lower than usual amp rating for an O scale engine. If you like the way these excellent engines run now, wait until you see their low speed operation with the back EMF cruise!
At the time, I used NWSL replacement wheelsets, and Atlas supplied everything else - wheel-wiper pickups, insulators for the pickups, even the screws necessary to install them. The basic truck frame was the same for 3-rail or 2-rail: pre-drilled for either the center rollers or the 2-rail wheel wipers.
