Using this train set is easy! First, make sure the battery is installed in the engine. Then, assemble the 9 track pieces to create your layout. Flip the switch on top of the engine to start Thomas racing into the Crystal Caves to complete his delivery. You can use the track switch to decide if Thomas goes over or under the tipping bridge. Remember, this set is for kids aged 3 and up. It's not suitable for children under 36 months because there are small balls that pose a choking hazard. To keep the set in good condition, store it in a dry place when not in use. If the engine doesn't work properly, check the battery. Additional track can be bought separately, but availability may vary.
