PARKING BRAKE FOR A RAIL CAR AND METHOD OF PROVIDING A PARKING BRAKE FOR A RAIL CAR
In one aspect the invention relates to a parking brake for a rail car that employs a threaded rod (22) that is coupled directly to the piston of a brake cylinder. A gear (52) having a set of internal threads is coupled to the threaded rod and can be selectively restricted by a pawl (54) that is biased by a spring into engagement with the gear to prevent movement of the piston into the brakes releases position. The pawl may be disengaged from the gear in response to sufficient brake pipe pressure by a piston (74) that is coupled to a source of brake pipe pressure and to drive a lever (70) into a pin (60) that can push the pawl against the bias of a spring (58). In the absence of brake pipe pressure at the piston, the spring will drive the pawl into engagement with the gear, thereby locking the threaded rod against movement and preventing release of the brakes. In a further aspect the invention relates to a method of providing a parking brake for a rail car.

A computer controlled locomotive brake (CCB) configured for setting and releasing the retainer valves of the railcars of a train. The CCB may initially recharge the brake pipe to a pressure slightly less than the retainer valve release pressure. The CCB may then continue charging to this level until the brake pipe flow, measured at the CCB on the controlling locomotive and the brake pipe pressure on the last car, as measured by an end of train device, indicate that the pressure in the braking system reservoirs are substantively equal to the brake pipe pressure. Once the reservoirs are substantively charged, the CCB may complete the brake release and recharge by recharging the brake pipe pressure to its final charge so that all retainer valves are released and the train has sufficient braking system recharge to safely control movement of the train.

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.

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.

A gladhand coupling that prevents inadvertent separation of the coupling halves without the need for additional structure or manipulation to connect and disconnect the halves. Each half is equipped with a lug having a ramped pad and a flange defining a channel having a corresponding ramped pad. When two halves are positioned together then rotated into the locked position, the ramped pad of the lug is positioned proximately to the ramped pad of the flange to prevent inadvertent lateral compression of the two halves that could cause unintentional uncoupling. The coupling may be disconnected by simple rotation of one coupling half relative to the other and by pulling the coupling apart as done by current rail car decoupling procedures without the need for manual manipulation of extraneous locking mechanisms.

A predictive maintenance system for determining when an item of equipment on a rail car is due for servicing. A server is configured to receive run data relating to a train and a database is associated with the server to maintain identifying information about the rail car, status information about an item of equipment, the date when the item of equipment will likely be due for servicing, and the current location of the rail car. The service date is calculated from the run data by estimating the amount of wear that likely has occurred based on the run data. The estimated amount of wear may then be used to determine the amount of wear remaining and the date when the equipment will likely reach its lifespan based on estimated use to date and the rate of usage.
A computer controlled locomotive brake (CCB) configured for setting and releasing the automatic parking brakes of the railcars of a train. The CCB may initially recharge the brake pipe to a pressure slightly less than the parking brake unlatch pressure. The CCB may then continue charging to this level until the brake pipe flow, measured at the CCB on the controlling locomotive and the brake pipe pressure on the last car, as measured by an end of train device, indicate that the pressure in the braking system reservoirs are substantively equal to the brake pipe pressure. Once the reservoirs are substantively charged, the CCB may complete the brake release and recharge by recharging the brake pipe pressure to its final charge so that all parking brakes are released and the train has sufficient braking system recharge to safely control movement of the train.
