An exciting new addition to the GeoTrax Rail & Road System, the Elevation Series lets kids take their imaginations to all new heights. The Clock Tower set includes a two-part clock tower that can be used separately or stacked to build up to the 3rd level! Drive the train through the 2nd and 3rd level tunnels and you'll get one of three fun sounds - a clock bell, a clock chime or a Glockenspiel tune! Also includes is a cross track piece, and it can be used with any other items in the GeoTrax System to create an even bigger world.
