Query: Doesn't stay on the track

The engine comes off the tracks all the time - even when it is used with track of the same brand (Thomas and Friends Wooden Railway). This is a pain. Our child is frequently asking us to help to get it back on the track.But more importantly, it is a disappointment for the child. Our 2 year old was extremely excited about this toy when he opened the present. After playing with it a short while he said "This train is bad. It's broken." That's not the memory you want your family to have on Christmas.It doesn't seem like it should be difficult to make a toy train go around a track reliably. Don't buy this toy.
