Using this Fisher - Price Thomas & Friends Beachy Nia toy train is super easy. First, insert 3 AAA batteries into the engine. Then, flip the switch on top of the engine, and the train will start moving along the track. You can connect this train to other Thomas & Friends trains, vehicles, cargo cars or tenders using the plastic connectors that come with it. Just line up the connectors and snap them together. When you're done playing, turn off the switch to save battery power. Keep the train away from water to prevent damage. If the train gets dirty, you can use a dry cloth to wipe it clean. Remember, the additional vehicles, play pieces, and track sets are sold separately, so you may need to buy them according to your needs. And since the trains are sold individually, you can collect different characters to have more fun.
