He was Thomas Edison's main rivals in the early implementation of the American electricity system. At age 19 he made his first invention, the Rotary Steam Engine. and the Westinghouse Farm Engine. At age 21, He made a " car replacer" which was a guide to derail railroad cars back onto the tracks, and a Reversible Frog. Once seeing a train accident where 2 trains were colliding and had a person running to each car to stop them manually, he had invented the air brakesin 1869. He invented The Westinghouse system which used a compressor on the locomotive, a reservoir and a special valve on each car, and a single pipe running the length of the train which both refilled the reservoirs and controlled the brakes, applying and releasing the brakes on all cars simultaneously. After the brakes were certified, Westinghouse invented The Westinghouse Air Brake Company ( WABCO) which was organized to make and sell his invention. In 1886 George Westinghouse and William Stanley installed the first multiple-voltage AC power system in Great Barrington, Massachusetts. In 1889, he formed the Westinghouse Electric and Manufacturing Company.
