Track call buttons would be an extension of the control unit start button, when a car de-slots during a race you push the start button on the control unit and it cuts power to the track and caution shows on the screen. When you push the start button a second time the count down begins to re-start the race. I would like to know if it is possible to add extra buttons around the track that would do the same as the start button on the control unit.
