Elevated Cross Over The elevated track crossover section comes as two, three quarter length track sections with pillars. This assembly helps build a more rigid fly-over section than fly-overs supported simply by pillars. Multiple C8295 crossovers can be stacked on top of each other to build crazy stunt or action tracks. SAFETY NOTICE Warning!
