Magnet couplers make coupling cars child's play for this high-speed five-part train set. There is a permanently coupled unit consisting of a motorized diesel locomotive and a bi-level passenger car with a built-in battery holder. The train has three speed levels in both forward and reverse, three sound functions and triple headlights. The train can be operated with 2 different frequencies (C/D), allowing you to add a second battery train. A track oval, wireless infrared controller and batteries are included.
