Railtrack

Railtrack was a group of companies that owned the track, signalling, tunnels, bridges, level crossings and all but a handful of the stations of the British railway system from its formation in April 1994 until 2002. The company was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index but on 3 October 2002, the main operating arm - the owner and operator of the national railway network, Railtrack plc - was sold by its parent company Railtrack Group plc to "not for dividend" company Network Rail (a company limited by guarantee) and was later renamed Network Rail Infrastructure Ltd.
