A system for waking up a dormant car control device 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 is used to output a predetermined voltage when a pressure switch 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 boosts the predetermined voltage of the supercapacitor and energized the contacts of a relay that can selectively provide the boosted voltage to an input of a car control device. A second circuit controls the relay to select when boosted voltage should be provided to the input of a car control device. A third circuit selectively provides power to the first and second circuits based on whether the car control device should receive the boosted voltage.

Car control device wake up for electrically controlled pneumatic train braking systems

A system that allows an electronically controlled pneumatic (ECP) railcar to be optionally selected as the ECP End of Train (EOT) device when that car is positioned at the end of a train regardless of its physical orientation. This eliminates the requirement to use and install a traditional End of Train (EOT) device at the end of an ECP train while maintaining the same train integrity monitoring functionality that is typically provided for train brake-in-two detection and closed cut-out cock detection. The system also eliminates the requirement for a dedicated EOT device at the end of the train for ECP 'RUN' Mode operation, and allows any ECP car to function normally as part of the train or act as the EOT device when selected.
