This item was purchased used. It's a set including one full loop of track, 27 train cars (photos 1 and 8), and 6 types of power car covers (photo 4). There are two powered cars (Doctor Yellow and SL), but you can swap the covers to use them with other car types. The powered cars have been tested and are working. Batteries are not included. There are some minor scratches, but they don't affect playability. #Plarail
