    A different kind of accident can occur if a malfunction in the air brake system (such as a broken air brake hose) causes the air brakes to engage unexpectedly. An example of this problem can be seen in the accident that caused the death of John Luther "Casey" Jones on 30 April 1900 on the Illinois Central Railroad main line at Vaughan, Mississippi.

    A pair of gladhand connectors between railroad cars A gladhand connector on a trailer. A gladhand connector or gladhand coupler is an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer, [1] or from a locomotive to railway air brakes on railroad cars.

    An air brake compressor is usually capable of generating a pressure of 90 psi (620 kPa; 6.2 bar) vs only 15 psi (100 kPa; 1.0 bar) for vacuum. With a vacuum system, the maximum pressure differential is atmospheric pressure (14.7 psi or 101 kPa or 1.01 bar at sea level, less at altitude). Therefore, an air brake system can use a much smaller ...

    When the brake pipe and car components are charged with air, the brakes release. When the engineer needs to make a brake application, control valves in the locomotive reduce the brake pipe pressure. As the brake pipe pressure is reduced, the service portions on each car divert air from their reservoirs to their brake cylinders.

    A box was designed with a yellow strobe light, and equipment for monitoring air pressure through the brake line was designed to be installed in the unused coupler of the last car. Later, as cabooses were phased out, railroads moved to their current use of an end-of-train device to mark the end of the train.

    Truck air-actuated disc brake. An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to both release the parking/emergency brakes in order to move the vehicle, and also to apply pressure to the brake pads or brake shoes to slow and stop the vehicle.
