A system (10) and method (50) for waking up a dormant car control device (16) of rail car braking system that provides a sufficient wake up voltage in response to pressurization of the brake pipe of the transit car. A supercapacitor (14) is used to output a predetermined voltage when a pressure switch (12) responsive to a source of brake pipe pressure moves to a closed position in response to a charging of the brake system. A first circuit (22) boosts the predetermined voltage of the supercapacitor and energized the contacts of a relay (24) that can selectively provide the boosted voltage to an input of the car control device (16). A second circuit (20) controls the relay (24) to select when boosted voltage should be provided to the input of the car control device (16). A third circuit (40) selectively provides power to the first and second circuits based on whether the car control device should receive the boosted voltage.
