Crank up the speed with the 36003 Turbo Train. Simply press the big turbo button and this battery-operated toy train doubles its speed, making it the fastest train in BRIO World. The turbo boost lasts for 5 seconds and as it runs at top speed, the white lights along the sides of the engine change to a cool blue. This futuristically designed engine also includes a passenger wagon with enough space for one lucky passenger to enjoy an exhilarating ride to remember.
