A new and improved Tube map featuring the Elizabeth line has been unveiled ahead of its official opening on 24 May.
The railway features a double purple line instead of a solid line to differentiate it from a London Underground line, Transport for London (TfL) said.
The line runs from Reading, Berkshire and Heathrow Airport, west London, to Shenfield in Essex and Abbey Wood, southeast London.
Trains will initially operate in three sections which are expected to be fully integrated in the autumn.
The new central section, built by the delayed Crossrail project, runs through tunnels from Paddington, west London, to Abbey Wood.
Services on the two other sections already operate as TfL Rail but will be rebranded from next Tuesday.
It is named in honour of the Queen, who made a surprise visit to Paddington station earlier this week to open the line.

The monarch, 96, was accompanied by her youngest son Prince Edward.
The first published version of the Tube map was 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.”
