Lionel Y3 6-38083 2-8-8-2 Norfolk & Western with TMCC, Odyssey speed control (switchable on/off) Railsounds and lots of other great features. See pic of box end for the whole list. Comes with original box, packaging and manual. It's diecast so it weighs a ton and you have to handle it with care. The front set of drivers swivels and tends to feel loose unless the engine is on the track. There is a tab with a spring on it that you can tighten to hold the front driver set closer to the boiler. But I never did that. It's not necessary as long as you support the front set of drivers when you are handling the engine getting it on and off the track. This loco has been run very little and shows it. It's gorgeous. The box has some dings at the flaps but nothing serious. Lionel promoted this as a scale engine and I believe them--it's BIG. It's a standout on any layout. $750 plus insured mailing. My email is in my profile.
