“All aboard!” - The trains are ready to depart from the Smart tech Sound Action Tunnel Station. Interactive Features: When used with the Record & Play Engine (not included), the Station Action Tunnel instructs the train to slow down to a complete stop, flash its lights to signal that it’s arrived and play a station sound to create a playful ambience. Once the train has halted, help the passenger onboard the Travel Wagon and begin your BRIO World journey. Customise the Station: Use the Smart Tech Sound app to change the station sound to recognisable stations from around the world – such as Berlin, London or Paris. Part of BRIO World: The Action Tunnel Station is best used with the Record & Play Engine (not included) to get the full sound experience but can be used with any train or vehicle in BRIO World, connecting to a wooden track layout via both the front and back connections. Smart Tech Sound Action Tunnel Station includes 4 pieces: 1x Action Tunnel Train Station, 1x Station Action Tunnel, 1x Travel Wagon, 1x Passenger.
