The BRIO 33974 Action Tunnel Circle Set combines a compact circular railway with interactive tunnel play. Introduced in 2020, the Action Tunnel adds an extra dimension to journeys around the track, creating more interaction than a traditional simple railway circuit. The set works well on its own while its track and interactive elements can also be incorporated into larger BRIO World layouts.
