This Train Track Racer Set is perfect for your little train engineer! Children will have to create a track of their own and then assemble their track design. The straight and curved pieces allow maximum configurations of the racing track. Once it is constructed it is time to place the locomotive on the track and watch as it races over the track going through bends, curves, loops and even upside down. Size/Packaging: 13"x12.5". Requires 2 AA batteries(not included).
