Westinghouse developed the air brake for trains.
A train's brakes start exerting force on the wheels when the brake system is activated by the engineer using either compressed air (pneumatic brakes) or electricity (electric brakes). The force applied by the brakes creates friction between the brake pads and the wheels, which slows down the train.
