An apparatus for changing a condition of a hand brake system on a railway car which has both a hand brake system and a service brake system. The change of hand brake system is made in response to one or more of a group of predetermined conditions. The apparatus has one or more sensors for detecting predetermined conditions requiring a change in the hand brake system, and for generating a signal indicating need for a change. The signal is used to trigger an electromechanical device for operating a quick release mechanism for the hand brakes.

Railway braking apparatus to effect a change in a handbrake

Apparatus for indicating the condition of hand brakes on railway cars and for applying and releasing railway car parking or hand brakes automatically in response to predetermined conditions including movement of a train, wayside conditioning apparatus, wayside operating mechanism, a signal controlled by an operator and performance of predetermined railway operating procedures, such as completion of an air brake test procedure. The apparatus may respond to mechanical, electrical and electronic signals and may operate on pneumatic or electric power provided from the service air brake system of a train or from a source of power outside of such air brake system.

Railway braking apparatus

Apparatus for indicating the condition of hand brakes on railway cars and for applying and releasing railway car parking or hand brakes automatically in response to predetermined conditions including movement of a train, wayside conditioning apparatus, wayside operating mechanism, a signal controlled by an operator and performance of predetermined railway operating procedures, such as completion of an air brake test procedure. The apparatus may respond to mechanical, electrical and electronic signals and may operate on pneumatic or electric power provided from the service air brake system of a train or from a source of power outside of such air brake system. A brake system for a railway train equipped with brakes is disclosed comprising a first device for applying such brakes to inhibit movement of the railway train, a second device operable under certain predetermined conditions to cause the first device to apply such brakes, a third device normally in a first condition but responsive to the application of such brakes by operation of such second device to assume a second condition, and a fourth device effective when the third device is in its second condition to provide an indication thereof.
