Brio Smart Tech Sound Adventure Set

Take the Smart Tech Sound train on a railway adventure with the 36033 Smart Tech Sound Adventure Set. This mountainous train set includes the Smart Tech Sound Engine, Danger Crossing and various Action Tunnels which you can move around to program the play. As the train approaches the crossing, it can tell if the safety gates are up or down and reacts accordingly – stopping and playing a sound to allow cars to pass when they are up, then continuing its journey once lowered.
