Saw your earlier listing first and checked "the pile" to see what I had. Have the engine 20-3239-1 w/High Rail wheels, which I bought slightly used and have never run; and the 3-car add-on set 20-62029A, B & C which have never been on the track. However, since you're no longer showing that you're looking for the cars, I'm not going to sell just the engine. Email shrugger59@aol.com if I'm misunderstanding here or if you're interested.
