Take control of the play with this 37-piece interactive toy train set - the Action Tunnel Travel Set. Added Smart Tech Sound technology allows the battery-powered Record & Play Engine to communicate with its surroundings, automatically responding to Smart Tech accessories with various train actions like multicolour lights, motion and sounds that enhance the imaginative play. Each Action Tunnel creates a unique response from the engine, and by actively moving them around the tracks, you can change the trains journey. Control the engines direction using the Change Direction and Stop Action Tunnels. Watch the engine slow down and stall after it passes through the Break Action Tunnel and then comes back to life as it leaves the Fix Action Tunnel. And hear your pre-recorded customisable sounds play after the toy train swoops under the Sound Action Tunnel. Program your train track layout the way you want to play and begin your BRIO World adventures. Ages 3 years+.
