IDEAS THAT BECAME INFRASTRUCTURE

A legacy built
on practical invention.

His achievements reached beyond a workshop. They changed transportation, electrical power, and the communities where industry took root.

01

The air brake

Westinghouse's railway air brake changed how trains stopped. His later automatic system provided a crucial safeguard: a loss of air pressure could apply the brakes, including when cars separated.

More dependable braking helped make railway travel safer and supported the growth of rail transportation.

Tesla & AC power

Westinghouse championed alternating current and backed Nikola Tesla's polyphase technology. Tesla's ideas, engineers' work, and Westinghouse's manufacturing helped turn electrical inventions into practical systems.

He helped carry new technology from the laboratory into everyday life.

Power on a grand scale

Westinghouse Electric illuminated the 1893 World's Columbian Exposition in Chicago. Westinghouse generating equipment at Niagara Falls became part of a landmark achievement in electric power.

Invention, manufacturing, and determination brought these ambitious projects to life.
