To use this train set, first assemble the 14.5 - foot track. Then place the motorized Thomas engine, Cranky the Crane, and the Troublesome Truck on the track. Turn on the engine and watch as the characters start interacting and talking to each other. Your child can use the kid - powered hopper to load and unload the 3 cargo pieces for added fun. When your child is done playing, make sure to turn off the engine and store the set in a dry place. Avoid getting the electronic parts wet. If the train set gets dirty, you can use a soft, dry cloth to clean it.
