A coupler head and mounting bracket combination for supporting a brake hose fitting uses a lug formed integrally with the coupler head and a support bracket mating with the lug. In embodiments, the bracket may be installed in a plurality of vertical positions on the coupler head. The bracket is maintained in a position inboard of the lateral side of the coupler head, to reduce or eliminate the likelihood that the bracket will interfere with the other equipment or the car body. Embodiments of the invention are particularly adapted for E type and F type coupler heads.

A communication system uses a vehicle system controller to control operation of a vehicle system. An electronic air brake (EAB) controller and an electronically controlled pneumatic (ECP) brake controller control operation of a brake of the vehicle system. One or more network connections communicate data packets between the vehicle system controller and the brake controllers to allow the vehicle system controller to control the brake of the vehicle system using data packets communicated between or among two or more of the vehicle system controller, the EAB controller, or the ECP controller to allow the vehicle system controller to control the brake of the vehicle system.

The patent was disclosed a telescopic mechanism in a telescopic hitch buffer device for use in high speed electric multiple unit (EMU) trains. The telescopic mechanism comprises a compression rod (2) located inside a movable housing (1) of said hitch buffer device, one end of said compression rod (2) being connected to the movable housing (1), and a bearing connector (3) encasing the compression rod (2). A guiding barrel (4) is fixedly mounted outside the bearing connector (3). An extension/retraction driving mechanism (9) is provided between the guiding barrel (4) and the movable housing (1). A locking mechanism comprises protrusions (6) distributed at the other end of the compression rod (2), and grooves (7) in engagement with protrusions (6) on the inner wall of the bearing connector (3). One end of the compression rod (2) is connected to the movable housing (1) via a torsion spring (5), keeping the compression rod (2) and the bearing connector (3) in a locked state; an unlocking driving mechanism is provided on the outside of the movable housing (1), and is in an unlocked state when the protrusions (6) face the grooves (7), in which case, the movable housing (1) and the bearing connector (3) can slide relative to each other. Since the extension/retraction driving mechanism (9) is provided inside the movable housing (1), volume is reduced, good protection is provided for respective components, and the telescopic mechanism and the locking mechanism are relatively simple in structure, labor-saving, reliable in operation, and can bear relatively large loads.

A knuckle pin, coupling system, and method for producing a knuckle pin are provided, the knuckle pin having a cylindrical body with a longitudinal slot therein separating vertical edges of the cylindrical body, with one or more first retaining elements that span outward of the cylindrical body, and a second retainer that includes one or more of opposing apertures, and bendable legs. A method for producing the knuckle pin is provided, where a blank is stamped into a workpiece that corresponds to the pin to be produced, and the stamped workpiece is rolled to produce the pin with the slot.
