New old stock - newer on the tracks. One unit is powered (54301), while the other (54302) is a roller with lighting. The two connect through a cable. I had the powered loco on a test stand, and it works like new - see YT video link below. Could use a little oil but I opted against putting it on to avoid soiling the box. (Use genuine Marklin oil, it really does make a difference.) Comes equipped with a Delta controller but will work on a conventional layout. The Delta controller is the early style with the dip switches, meaning it's really easy to change the address.

Both boxes are partially ripped (retaped where necessary) and heavily scuffed as seen in photos. The plastic covers both have a fingernail-size hole in them and have also been retaped.
