I have a very nice early P2K SD9 Chessie System (DC) that needs a new home. I have had tracking issues with it, that I will chalk up to my track work and tight radius turns on my small layout. I purchased the locomotive as NOS, and it has hardly seen any run time since I bought it. It is quiet and has great detail. Given the tracking issues I’ve experienced on my small layout, I am willing to let it go for best offer - or I am open to trades for a smaller loco. If your layout has wide turns, this should be a very nice runner. Send me a private message if you’re interested. Pictures below (original box, paperwork and optional detail parts are all there).
