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. All trains need a good wash now and then. Especially after traveling through the magical world you have built. The rollers roll and the train moves by itself as the sound of water and bubbles comes from the station. Soon the train will be shiny again! Based on smart interactive technology with action chips. Includes 1x Figure, 1x Train Wash station. The item measures 30.6 x 15.8 x 11.1cm. Suitable for ages 3 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. BRIO products are made from very high quality plastic and Beech wood from sustainable sources. 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!
