Wow! so much fun is included with this lovely battery operated BRIO My first railway set. Start by building a track layout with the mountain blocks and the tunnel, then let your train go up and down and through the tunnel. Press the arrow button on top of the engine and the train starts to move by itself. Automatically flipping magnets make connecting trains easy for young children. Patented ramps help pushing the train on the track. The wagon with the spinning wheel provides extra fun to this brilliant 'My first' set. Complete layout measures approximately 27.75" x 19" inches. Suitable for ages 18 months and up. Requires 1x AA battery not included.
