WAB

Westinghouse Air Brake Technologies Corporation

A maker of railway equipment and locomotives, Wabtec builds gear used by railroads, subway systems, and bus fleets around the world and is one of the largest locomotive manufacturers anywhere. It began when George Westinghouse, then 22, founded the Westinghouse Air Brake Company in 1869 to sell his compressed-air brake that let one engineer stop a whole train at once. The name Wabtec was stitched together from "Westinghouse Air Brake Technologies" after a 1999 merger.
