LIONEL TRAIN PARTS. I have over 4000 Lionel part numbers in stock so you can repair your Lionel trains. Most of the parts are post war, some MPC , LTI & reproduction. I don't have any prewar or HO or G gauge parts. Abbreviations used after part number are L = LTI, M = MPC, N = new, O = original, R = repro, U = used, rb = rebuilt.
