Using this BRIO remote - controlled travel train is a breeze. First, insert 4 AA batteries into the train (the batteries are not included). Then, turn on the train and the controller. You can use the controller to drive the train forward at two different speeds, reverse it, or stop it. There are also A&B frequencies on the controller, which means you can have multiple RC trains on the same layout without interference. Press the buttons on the controller to add light and sound effects. If you prefer, you can control the train directly using the buttons on the engine. Remember, this train is for kids aged 3 and up. Keep the train away from water and rough handling. When not in use, store it in a dry place. If the train stops working properly, check the batteries first and replace them if needed.
