20090229932 | BRAKE PIPE VENT VALVE FOR LOCOMOTIVE BRAKE SYSTEM - The present locomotive brake system includes a brake controller operable by an operator and a brake pipe vent valve. The brake controller includes an emergency output port which provides emergency pneumatic signal on the emergency output port when the brake controller is in an emergency position. The brake pipe vent valve includes a housing having brake pipe, emergency input and exhaust ports, and a first valve. The emergency output port is fluidly connected to the emergency input port. The first valve selectively connects the brake pipe port to the exhaust port when opened in response to an emergency signal on the brake pipe port and in response to an emergency signal on the emergency input port. | 09-17-2009 |
20090217747 | Single Car Trainline Tester - A test device includes a trainline connector for connecting the test device to a car trainline to which the electropneumatic brake device is connected and includes a power port to receive power for the trainline at a first voltage. A power switch selectively connects the power port to the trainline connector. A test switch selectively connects a test voltage smaller than the first voltage to the trainline connector. A sensor senses an electrical parameter of the trainline. A controller a) initially controls the power switch to disconnect the power port from the trainline connector, b) subsequently controls the test switch to connect the test voltage to the trainline connector and c) if the sensor senses an electrical parameter indicative of an acceptable trainline, controls the test switch to disconnect the test voltage from the trainline connector and controlling the power switch to connect the power port to the trainline connector. | 09-03-2009 |
20090210106 | LOCOMOTIVE AIR/VACUUM CONTROL SYSTEM - The present locomotive brake control system includes a vacuum relay valve responsive to air brake apply and release signals on the air brake pipe to provide vacuum brake apply and release signals on a vacuum brake pipe. A locomotive brake controller is responsive to the brake apply and release signals on the air brake pipe to control the brake cylinder to apply and release the locomotive brakes in an air mode, and is responsive to the brake apply and release signals on the vacuum brake pipe sensed by a transducer to control the brake cylinder to apply and release the locomotive brakes in a vacuum mode. | 08-20-2009 |
20080288131 | METHOD OF ENTRY AND EXIT OF A REMOTE CONTROL MODE OF A LOCOMOTIVE BRAKE SYSTEM - A method of transitioning a locomotive brake control system between a remote operated locomotive RCL mode and an electronic air brake EAB mode includes initializing the system in the EAB mode; and determining a value of an RCL enable. Transitioning from the EAB mode to the RCL mode includes a) determining if the system is ready to be transitioned to the RCL mode if the RCL enable is high, and b) transitioning the system to the RCL mode if the system is ready for transition and the RCL enable is high. Transitioning from the RCL mode to the EAB mode includes a) determining if the system is ready to be transitioned to the EAB mode if the RCL enable is low, and b) transitioning the system to the EAB mode if the system is ready for the transition to the EAB mode and the RCL enable is low. | 11-20-2008 |
