It's an amazing track with a steep motorized ramp with rollers that takes your cars to the top of the tower, and sends them spiraling down into an epic jump! Then park at the rooftop parking lot good for 2 cars. You can also connect it to the BYUN BYUN CIRCUIT RACE TRACK for a bigger and more exciting layout! Works with cars in the 1:64 scale, such as Tomica and Hot Wheels cars. Cars are not included, 4 "D" size batteries required. Note that transparent cover on top of the motorized ramp need to be placed properly for the motor to work.
