TfL has, just in time for the launch, released its latest tube map which now includes the Elizabeth line, along with a new sponsor and the London Overground extension.

As with other mainline sized services, the Elizabeth line appears on the tube map 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.
The Elizabeth line will initially run 12 trains per hour between Paddington and Abbey
