It's very easy to play with the Hape NTERCITY BATTERY LOCOMOTIVE. To power the locomotive, all you need is 2 AAA batteries. Then place it at the front of the train and press the button to move it forward or backward. This locomotive will become a popular means of transport. This locomotive will not let children get bored, as it is specially designed to pull carriages from other Hape and Brio sets. Easily handles climbs, turns and steep descents. There is a magnet at back of the locomotive that allows freight and passenger carriages from other sets to be added.
