"My boys aged 3 and 6 both really enjoy this set. I got the additional tracks and bridge. It’s easy enough for my 3 year old to help build tracks and operate the train; and my oldest likes making more complex designs. When their friends are here there’s enough for 4 kids. Both girls and boys enjoy this set. This also goes with other Duplo bricks and some vehicles fit on the tracks too, it can even be raised up off the floor. If the kids have imagination there’s lots to do with it. I haven’t had issues with it, and it goes up and down the bridge easily until batteries run low.
*I would have liked a second option to get another/different train, the cargo train has been out of stock for awhile. And also an option to buy spare and different coding/function tabs would be cool.
