Westinghouse Rail Systems Ltd

Westinghouse Rail Systems Ltd (formerly Westinghouse Signals Ltd) was a British supplier of railway signalling and control equipment to the rail industry worldwide. Its head office was in Chippenham, Wiltshire, where it manufactures a variety of mechanical and electrical/electronic railway signalling equipment. It had six other UK offices in Croydon, York, Birmingham, Crawley, Swanley and Glasgow. It also has a number of overseas offices, particularly in the Far East, including Melbourne.

Westinghouse was deemed to be the largest signalling design and control engineering company within the UK. Westinghouse sealed its biggest ever contract in 2004. The £850 Million contract was issued to Westinghouse by Metronet, and was for the resignalling of eight of the London Underground lines. The ten-year contract is part of the PPP (Public-Private Partnership) funded regeneration of the Underground system, and will run until 2014.

The company was owned by Invensys plc, before being sold to Siemens in 2013. The Westinghouse name has now been dropped and is now Siemens Rail Automation.


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]

The brake and signal company split into two separate companies: Westinghouse Signals and Westinghouse Brakes. Invensys sold Westinghouse Brakes to Knorr-Bremse in April 2000.[2]
