| | City Mayors: London Underground and Tube |
 | | The latest surface and tube cars have passenger-operated doors with push-button control, ensuring that on open-air sections of the Underground (over half the system, despite its name) only those doors though which passengers wish to alight or board are opened, conserving train heating in cold weather. |
 | | In 1933, the London Passenger Transport Board was created to oversee all public transport in the capital and in 1948 this was officially nationalised as the London Transport Executive, a division of the British Transport Commission which also controlled airports, docks, railways and road freight. |
 | | The tube station was intended from the start to be the showpiece of the Jubilee Line Extension, and its design was awarded in 1990 to the renowned architect Sir Norman Foster. |
