Crossrail

Crossrail is a completed railway project centred on London. It provides a high-frequency hybrid commuter rail and rapid transit system known as the Elizabeth line, that crosses the capital from suburbs on the west to east and connects two major railway lines terminating in London: the Great Western Main Line and the Great Eastern Main Line. The project was approved in 2007, and construction began in 2009 on the central section and connections to existing lines that became part of the route, which has been named the Elizabeth line in honour of Queen Elizabeth II who opened the line on 17 May 20
