This was purchased at an estate sale where someone else bought the box only separately. I found two small bins filled with legos that I knew at contained some of the pieces that went to this set were part of. There are a lot of important pieces in this set. Such as the tracks, the 9v power supply train, minifigures, and the stands for the tracks. In the upper left are some pieces that I know are a mix of pieces that do not go to this set. And some that also may be part of the set. Please keep in mind the pieces in the main pile may not all go to this set. Everything in the pictures is included. I was not able to test the 9v engine due to not having the wire.
