Item number A-4850. The lights and motor have been confirmed to be working prior to listing. The Arnold couplers have been replaced with Tomix close-coupling TN coupler SPs. The lead car has electrical connectors. The motor unit of the M car was malfunctioning, so it was replaced with a Tomytec Railway Collection motor unit TM-18. At that time, the underfloor equipment was modified and attached using the original parts (see photos). There are no noticeable scratches, but please purchase only if you understand that this is a used item. The case cover is not included. Also, the case is cracked and has been reinforced with drafting tape.
