With its shiny gold, metalized paint and classic "choo-choo" sound, the 33630 Mighty Gold Action Locomotive impresses everyone as it flies down the tracks at high speed. Battery-powered action: This battery-powered toy train is one of the strongest in BRIO World and drives forward and reverse with accompanying light and sound effects. It also features a switch on top which allows you to use the train without the battery function – disengaging the axel for free-wheel rolling.
