Abstract:
An assembly has a handle, a brush holder, and a support that connect and disconnect to each other using a locking mechanism. The handle reversibly connects and disconnects from the brush holder. The locking mechanism includes a connecting member on the brush holder that attaches to the handle by interaction of a locking flange on the connecting member with a pair of teeth inside of the handle. Insertion of the support within the brush holder extends a post on the support through the connecting member to interact with the handle and enable disconnection of the handle from the brush holder when the support is fully engaged by the brush holder. The locking mechanism prevents the handle from releasing from the brush holder before the brush holder is completely seated on the support.
Abstract:
A system, method, and apparatus for certifying an end-of-train device pressure calibration is provided. The system includes an end-of-train device including a brake pipe interface adapted to be removably connected to a brake pipe system of a train and to receive air having a pressure from the brake pipe system, and a pressure sensing device configured to measure the air pressure received in the brake pipe interface to obtain a measured pressure. The system also includes a pressure calibration device adapted to be removably connected to the brake pipe interface when the end-of-train device is removed from the train, the pressure calibration device configured to output air at a regulated pressure to the brake pipe interface, and at least one controller programmed or configured to determine a calibration certification result based at least partially on a difference between the measured pressure and the regulated pressure.
Abstract:
A system and method for detecting broken rails in a track of parallel rails includes at least one first broken rail detection module configured to measure a current through the track and a central control system configured to determine a location of at least one train on the track. The at least one first broken rail detection module is configured to send the central control system a signal based on the measured current. The central control office is configured to determine if a broken rail exists on the track and/or a location of the broken rail on the track based at least partially on the measured current and the location of the at least one train on the track.

Abstract:
A main piston bushing for a service valve portion of a brake control valve includes a cylindrical sidewall defining a central passageway extending longitudinally through the main piston bushing, the central passageway being surrounded by an internal surface of the cylindrical sidewall. The central passageway is configured to receive the main piston assembly of the service valve portion. The internal surface of the cylindrical sidewall includes a first ramp and a second ramp defined therein, the first ramp and the second ramp being configured to engage a portion of the main piston assembly of the service valve portion to restrain movement of the main piston assembly.
Abstract:
A contaminant mitigation device for use with a slack adjuster for a railway brake rigging to protect the critical operating area of the slack adjuster. The critical operating area of a slack adjuster includes the components that are configured to operate together to adjust the brake rigging. The slack adjuster includes at least a main housing portion, a cone nut housing portion enclosing the critical operating area of the slack adjuster, and an overtravel housing portion. The contaminant mitigation device includes a sealing system configured for cooperating with at least one of the main housing portion, cone nut housing portion, and overtravel housing portion to seal the critical operating area against entrance of fluid and/or contaminants therein and/or to at least reduce the exposure of this area to fluid and/or contaminants. The contaminant mitigation device can also include a drainage system associated therewith.
Abstract:
A spring-biased lever arm mechanism for operating an operating lever of a parking brake release mechanism. The lever arm mechanism includes a lever arm mounted on a pivot pin, a torsion spring disposed on the pivot pin, and first and second cable release mechanism. A manually operated parking brake release mechanism is also provided for a railway vehicle including a brake actuator, an operating lever associated with the brake actuator to manually release an applied braking force, and the spring-biased lever arm mechanism for operating the operating lever.
Abstract:
A transition plate connects an electronic manifold to a pipe mounting bracket of a railway brake system and includes a body having a manifold portion that defines a face configured to engage the manifold and a pipe bracket portion that defines a face configured to engage the pipe mounting bracket; ports defined in the manifold face that are configured to align and communicate with ports in the face of the manifold; ports defined in the pipe bracket face that are configured to align and communicate with ports in the face of the pipe mounting bracket; and a plurality of air passages extending through the body for connecting the plurality of ports defined in the manifold face with the plurality of ports defined in the pipe bracket face. The transition plate establishes a pneumatic interface between the electronic manifold and the pipe mounting bracket.

Abstract:
A system, method, and apparatus for certifying an end-of-train device pressure calibration is provided. The system includes a pressure calibration device configured to output a regulated pressure; and an end-of-train device comprising: a brake pipe interface adapted to receive the regulated pressure from the pressure calibration device; and a pressure sensing device configured to obtain a measured pressure by measuring the regulated pressure. At least one of the pressure calibration device and the end-of-train device comprises at least one controller configured to determine a calibration certification result based at least partially on a difference between the measured pressure and the regulated pressure.
