Abstract: A parking brake for a railway vehicle includes a pneumatic cylinder having a cylinder wall, a first wall opposite a second wall, and a piston movable within the pneumatic cylinder. At least one spring extends between the piston and the second wall for biasing the piston against the first wall. A gear box is fixed relative to the second wall and includes a hand wheel. A spindle is operatively connected to the gear box to affect movement of a manual reset mechanism having a threaded shaft and a ball screw nut rotatably engaged with the threaded shaft. A pushrod is connected to the manual reset mechanism and extends through the cylinder and the first wall. When the hand wheel is rotated, the manual reset mechanism is rotated to cause the pushrod to move relative to the piston corresponding to the direction of the rotation of the hand wheel.

Abstract: A handbrake for a railroad car includes a handbrake body having one or more gear train components therein and a drive shaft operatively connected to the one or more gear train components. An intermediate pinion shaft is operatively connected to the drive shaft through one or more gears. A shaft alignment link is adapted for maintaining a relative spacing between the drive shaft and the intermediate pinion shaft during rotation of the drive shaft. A gear box housing is provided to enclose at least a portion of the drive shaft, the intermediate pinion shaft, and the shaft alignment link. The shaft alignment link is movable relative to the gear box housing due to any eccentric movement of the drive shaft to maintain the proper spacing between the drive shaft and the intermediate pinion shaft, thereby eliminating a possibility of gear binding. A method for aligning internal gear components within a handbrake and an alignment system for use with a railway vehicle handbrake is also provided.

Abstract: A sealing assembly for sealing a gap between a swing door and a floor comprises a sealing member installed to be able to rotate from a closed position to an open position, an elastically deforming member made of an elastomer composition engaged to the sealing member, and a seal driving member to rotate the sealing member from the closed position to the open position when the door is opened. The elastically deforming member is deformed when the sealing member rotates from the closed position to the open position, and the sealing member returns from the open position to the closed position by elastic force of the elastically deforming member when the door is closed.

Abstract: A derailment detector for a railway vehicle includes a housing in selective fluid communication with a brake pipe of the railway vehicle to receive compressed air from a pneumatic braking system. A main chamber is disposed within the housing and pressurized by the compressed air. A shock detection assembly is adapted for detecting an acceleration indicative of a derailment condition and activating a main valve disposed within the main chamber upon detection of the acceleration indicative of the derailment condition. A discharge valve is in selective fluid communication with the main chamber, where, upon detection of the acceleration indicative of the derailment condition, the discharge valve is operative for discharging a predetermined amount of the compressed air from the main chamber to indicate that the derailment condition has occurred.

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 method and a system for transmitting enforceable instructions in a positive train control (PTC) system includes receiving, by a cyclic redundancy check (CRC) calculator, at least one enforceable instruction from railroad systems. The CRC calculator calculates at least one enforceable instruction CRC based at least partly on the at least one enforceable instruction and transmits the at least one enforceable instruction CRC to a back office server of the PTC system and/or an on-board system of a locomotive. Methods for cyclic redundancy check (CRC) hazard mitigation in a positive train control (PTC) system and verifying enforceable instruction data on-board a train are also disclosed.
