The motorized freight train chugs around the tracks, through the tunnels and up hills on its own! The train responds to the playset's nine SmartPoint locations with fun phrases, music and more. The gold mine includes rotating gears, a crane to move the shape pieces around and a mine shaft where you can pretend to mine for gold. The train plays three sing-along songs and helps learn the letter "F". All VTech Go! Go! Smart Wheel, Animal and Friends connect together.
