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 1 x figure, 1 x smart engine, 1 x carriage, 1 x buffer, 3 x smart tech arch, 9 x pieces of track and 1 x walk bridge. Track layout measures 59 x 51.4cm. Suitable for ages three years and up. Manufactured to BRIO's high standards and from FSC Certified wood. Each set is fully compatible with other BRIO sets, tracks and trains. The trains, wagons, carriages, and road vehicles all feature the classic BRIO magnetic couplings allowing for easy connection to each other. Check out the rest of the Smart Tech range today!
