With the Derby Magic Drag Racer technology, each lane of your track will have an individual start switch to energize the solenoid in that specific lane. We offer our Drag Racer in not just a 2-lane race but in every size track we have (2,3,4,5,6,8-lanes). Each of the switched will be labeled with the corresponding lane for ease of use and will have Velcro on the frame and the switches for storage during race days.
