Item number: A-4840 Before listing, I have confirmed that the lights and motor function properly. 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 disassembled and reassembled for adjustment. During this process, there was some slight deformation of the tabs used to secure the floor parts. The insulators have been painted white. There are no noticeable scratches, but please purchase only if you understand that this is a used item. Please note that there is no case cover.
