The Safety Appliance Act is a United States federal law that made air brakes and automatic couplers mandatory on all trains in the United States. It was enacted on March 2, 1893, and took effect in 1900, after a seven-year grace period. The act is credited with a sharp drop in accidents on American railroads in the early 20th century.

The result of putting the air brake valve into the Big Hole position will cause the instantaneous total loss of all brake air pressure in the train line which causes the brakes on all train cars and engines to automatically apply creating an emergency stop of the train. This action is called, "Big Holing It".
A single line item in the procurement forecast for the U.S. State Department included $400 million in armored Teslas, but after a flurry of news broke about the potential order, both Tesla CEO ...
European brake systems vary between countries, but the working principle is the same as for the Westinghouse air brake. European passenger cars used on national railway networks must comply with TSI LOC&PAS regulation, [12] which specifies in section 4.2.4.3 that all brake systems must adhere to the EN 14198:2004 standard.
Being an automatic brake, this system applies braking effort if the train becomes divided or if the train pipe is ruptured. Its disadvantage is that the large vacuum reservoirs were required on every vehicle, and their bulk and the rather complex mechanisms were seen as objectionable. The Westinghouse air brake system. In this system, air ...
Foundation components are the brake-assembly components at the wheels of a vehicle, named for forming the basis of the rest of the brake system. These mechanical parts contained around the wheels are controlled by the air brake system. The three types of foundation brake systems are “S” cam brakes, disc brakes and wedge brakes. [3]
