Smart Engine Set With Action Tunnels

The 33873 Smart Engine Set with Action Tunnels is a 17-piece interactive BRIO World railway set introducing BRIO’s original Smart Tech system. The battery-powered Smart Engine communicates with special Action Tunnels placed around the track, automatically triggering different actions such as stopping, reversing direction, sounding its horn and flashing its lights. A Smart Tech bridge, passenger wagon and figure complete the layout, allowing the position of the tunnels to be changed to create different automated railway journeys.
