It's not long now until the long-awaited Elizabeth Line will officially be open on the London Underground. 

And ahead of its opening, Transport for London has released a new Tube Map with the new line included for the first time. 

The addition comes just a few days before the grand opening on May 24. 

With line displayed as a double purple line rather than a solid line to “differentiate the Elizabeth line as a new railway as opposed to a London Underground line”, TfL said.

The Elizabeth line stretches from Reading in Berkshire to Heathrow in west London to Shenfield in Essex and Abbey Wood in south-east London.

Initially, trains will operate in three sections, which are expected to be integrated in autumn. 

The line is named in honour of the Queen who made the visit to Paddington station on Tuesday to mark the completion of Crossrail. 

The map also includes the Bank branch of the Northern line, which reopened this week after a 17-week closure for major upgrades, and the London Overground extension to Barking Riverside, which launches in the autumn.

The Tube map is based on a design by London Underground electrical draughtsman Harry Beck in 1931 with the first published version released in 1933.

TfL’s interim customer and revenue director Julie Dixon said: "Our world-renowned map now has another iconic addition in the Elizabeth line, which will serve London and the South East for hundreds of years to come.

"When we open on Tuesday May 24, the new Elizabeth line will begin providing greater connectivity and step-free access from Reading and Heathrow to Shenfield and Abbey Wood through the centre of London.

"This latest Tube map is a real credit to the team who have put it together.
