Zip Track Flexible Speedway  -- Discovery Toys.  The snappy racetrack your click together becomes a rally roadway with a crossover start gate that lets you control the action on the track! Race the two cars on separate tracks, or flip the lever on the crossover gate to turn your raceway into a figure eight. ZIP TRACK^TM RALLY includes two cool cars for twice the fun, and the cars have working headlights! There are 120 track pieces, a "rock" bridge, a "wooden" bridge and an interactive crossover start gate.  Playing with ZIP TRACK^TM RALLY helps children develop thinking skills, fine motor skills and social skills. Each car is powered by one AA battery (not included).
