London's latest subterranean commuter route, Crossrail's Elizabeth Line, has prompted change to the capital's iconic Tube map once again.
The first section of the Elizabeth Line between Liverpool Street and Shenfield has already opened, albeit under the branding of TFL Rail.
Transport for London's (TfL) newest version of the Underground map shows how the capital's transport will be look by 2019.
Unveiling the name of the new line on Tuesday, the Mayor of London, Boris Johnson, said: “Queen Elizabeth has given extraordinary service to this country over an unprecedented period and it is entirely right that she should be honoured with a living tribute that will last for centuries.”
Johnson is believed to have come up with the name himself.
It will initially be known as Crossrail, before becoming the Elizabeth Line once trains begin to run through central London.
