The LEGO? DUPLO? 10874 Steam Train is now even easier for your toddler to control and interact with in multiple ways. Young children can become the train driver with the Push & Go motor ? a gentle push either forwards or backwards sends the train on its way and a firm hold or lift off the tracks will make it stop. Help them place the 5 colored action bricks along the track to sound the horn, turn the lights on and off, pause and refuel, change direction and stop the train wherever they like.
