We purchased this and another one simular to this for christmas last year. Its a royal pain. It has to be set just right on the tracks if not...it will not run just comes off the track...and its not easy to get it to stay on there. Once it is on there...you can not touch it otherwise you will spend another 20 minutes trying to get it back on. My son was 3 and trying to tell him to just watch was useless. we packed up bolth and brought them to the good will store. It was such a hassle and way to many little pieces to put together. Stick with the wooden trains and tracks the kids love to scoot them around and put the tracks together...more hands on. This was a waist of my money.
