The Brio Smart Tech Sound Dangerous Level Crossing adds an interactive play experience to the wooden railway. This set combines mechanical elements with modern technology. When the orange barriers are open, they signal danger and bring matching Smart Tech locomotives to a stop. After the barriers close, the train cautiously crosses the cracked track structure. An included action tunnel triggers realistic ambient sounds, such as rockfalls or earthquakes, as the train passes through, bringing the play scenarios to life. The set easily integrates into existing Brio rail networks and fosters a creative understanding of rail safety.
