LEGO Steam Train 10874 Building Set (59 Pieces)

Purchased this for my 2.5 year-old son, and we love to play with it. I was looking for something that is versatile enough for me too, because we play a lot together, and this set, along with the bridge and the additional tracks, ticked all boxes on my list. I knew that if I get excited about a toy, my son will too, and the fun multiplies. The push and go motor is a brilliant thing, it works really well, although we don't use the mobile app. There's no need for that, you can play without it perfectly fine, and mobile devices are off limit for my son anyway. Not a cheap toy, but considering the many hours of play we'll put into it, it's a good investment. After a few days of play, one morning my son started building tracks on his own. He's yet to figure out how to build a loop, and this is the kind of challenge he needs right now. I'm very pleased with this toy, it moved all our other Duplo sets to a new level. I will probably buy the cargo set too, but that only for Christmas.

1, This train uses 4 AAA batteries. 2, This train's underneath contains a camera-light liked colour recognised sensor to recognise the action blocks. Actually you can replace the action blocks with the same coloured material like paper, the train can still read it and implemented the relevant actions. 3, The tracks are compatible with other Duplo's manual push trains, as long as you don't fit with a switch-track from other Duplo track set like 10882. You can push along the manial train with these tracks, or even connect the manual coach/car to this batteried train and pulled by it. 4, You cannot change the speed or this train manually on this physical train blocks. But you can choose the speed of this train via the free Duplo train app available in App Store. The default speed of physical train is maximum. You can slow it down only via this app. 5, This app connects between the device and the train via Bluetooth.
