Control handle and valve for a Westinghouse Air Brake. A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on March 5, 1868. The Westinghouse Air Brake Company (WABCO) was subsequently organized to manufacture and sell Westinghouse's invention.
Cars. Automobiles began using air brakes as early as 1903. The first car to have them was called a Tincher. As improvements continued to be made to car air brakes, a vacuum power booster braking system was developed that is similar to modern air brakes.
