Westinghouse Rail Systems' origin is in the signals division of Westinghouse Brake and Signal Company, which was founded as Westinghouse Brake & Saxby Signal Company in 1920. Hawker Siddeley purchased that company in 1979 and sold it to BTR plc in 1992.[1] In 1999, BTR merged with Siebe to form Invensys.[1]
Invensys split the business into two companies, Westinghouse Signals and Westinghouse Brakes, then sold Westinghouse Brakes to Knorr-Bremse in April 2000.[2] Westinghouse Signals (invensys) is now part of Siemens Mobility.
