Yup, it's a strange one Knight Train. It's my guess that someone did a lot custom work on it. It looks clean, and the additions look nice. I just don't trust the seller. He assured me that the train was "stock" and nothing had been done to it. Then, in a later e-mail, told me he didn't know anything about Playmobil trains.
At the current price this auction is worth it just for the two motor blocks and the box. I'll watch and see. If you pick it up could you let me know how it turns out?
