Smart Tech is the new Train technology from BRIO! Simply press go on the engine and set up the Smart Tech arches around the track. The Engine will automatically detect each arch and do exactly what is shown. It could stop,start, go slow, turn on the lights or make a sound. Isn't that fun. Where will the train go next? And what will it do? It’s all up to you. Arrange the tunnels and station and watch a new train adventure unfold. Thanks to interactive smart technology the train stops, honks the horn, backs up or blinks its lights. You make it happen! Includes 1x Figure, 1x Smart Engine, 1x Carriage, 1x Buffer, 3x Smart Tech Arches, 9x Pieces of Track, 1x Walkbridge. Track layout measures 59 x 51.4cm.
