Using this Fisher - Price Thomas & Friends toy train is super easy. First, insert 3 AAA batteries into the engine. Then, flip the switch on top of the engine, and it will start moving on the track. You can attach other Thomas & Friends trains, vehicles, cargo cars or tenders using the plastic connectors that come with the engine. Remember, additional items and track sets are sold separately. When not in use, turn off the engine to save battery life. Keep the train away from water and rough play to avoid damage. If the train gets dirty, you can gently wipe it with a dry cloth. Enjoy the fun railway adventures with your little one!
