Westinghouse is 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, owned by Invensys plc, is part of the Invensys Rail Group.
