In April 1994, the Waterloo & City Railway, by then owned by British Rail and known as the Waterloo & City line, was transferred to the London Underground. In 1999, the Jubilee Line Extension project extended the Jubilee line from Green Park station through the growing Docklands to Stratford station. This resulted in the closure of the short section of tunnel between Green Park and Charing Cross stations. The 11 new stations were designed to be "future-proof", with wide passageways, large quantities of escalators and lifts, and emergency exits. The stations were the first on the Underground to have platform edge doors, and were built to have step free access throughout. The stations have subsequently been praised as exemplary pieces of 20th century architecture.
