A parking brake control module using pneumatic logic to control a parking brake on a railway vehicle. The control module includes a brake pipe passageway, a reservoir passageway, a reservoir release valve, and an actuation cylinder vent valve. The control module applies or releases the parking brake based on pressures of the brake pipe and reservoir. A method uses pneumatic logic to control a parking brake on a railway car. The parking brake is applied when the brake pipe pressure falls below a lower brake pipe pressure threshold and is released when the brake pipe pressure exceeds an upper brake pipe pressure threshold and the reservoir pressure exceeds a reservoir pressure threshold. A hold valve can allow an operator to manually prevent the release of the parking brake.

The invention relates to a railway braking system comprising a connection device (7) having a lower part (14), an upper part (15) distinct from the lower part, two main posts (16) connecting the lower part to the upper part, and an attachment portion (18) forming a single anchor zone via which the system is configured to be mechanically secured to a railway vehicle, the system further comprising a brake linkage having levers (12) mounted with the ability to rotate about the two main posts, and a service and/or parking brake configured to act on the braking member as a result of actuation of the levers, with the connection device comprising at least one additional post (17) that also connects the lower part to the upper part and is positioned closer to the attachment portion than are the two main posts.

A system, e.g., for connecting a tie bar or other suspension member to a magnetic device in a magnetic track brake device, includes a bolt, a washer, and a taper dowel. The bolt includes a shaft having a first end and a second end, and a head attached to the first end. The washer is configured to fit about the shaft. The taper dowel is configured to fit about the shaft. The second end of the bolt shaft is configured to fit into a first aperture in the magnetic device, and the taper dowel, disposed about the shaft, is configured to fit within a second aperture in the suspension member. The second aperture corresponds in shape to an outer peripheral surface of the taper dowel, for the bolt to connect the suspension member with the magnetic device.
