This train is good used condition. The set includes the engine, 2 box cars, 1 key, and 6 train tracks. I did not pull this out of the box to test it, so it is being sold as is. Please see images for specific details. The engine measures approximately 4 3/4" x 2" tall x 1 1/4" wide. The box cars measure approximately 4" long x 1 1/2" tall x 1 1/4" wide. The original box measures approximately 11" x 6 1/2" x 1 3/4".
