Gunny, I thought that I read either here or on the old atlas forum that atlas had this tooling. I could be very mistaken though. I would think that Lionel has it considering their sd70macs look similar, at least the shell anyway. While comparing the one that I have to actual pics, I think the Kline version is off as well. Personally I would rather see a completely newly tooled model, that I don't have to convert to 2 rail myself.
