This Battery Operated T-Rex Train set contains 9 pieces and runs on two AA batteries. Multi-colored dinosaur cars run on train tracks.
One of the pieces of plastic track that came with the set had a molding defect so that the track was not complete all the way around. Every time the (T-rex) train passes that portion of track, it falls off, making the main function of the toy completely useless. A wasted $14.99.
