Crossrail is to be named the Elizabeth line, in honour of Her Majesty the Queen, when passenger services start in 2018.
The change of name, which was first proposed by Mayor Boris Johnson in 2013, was confirmed during a visit by Her Majesty to the under-construction Bond Street station.
Mayor Johnson said: “Crossrail is already proving a huge success for the UK economy, and as we move closer to bringing this transformative new railway into service, I think it’s truly wonderful that such a significant line for our capital, will carry such a significant name from our country.
“As well as radically improving travel right across our city, the Elizabeth line will provide a lasting tribute to our longest serving monarch.”
Mike Brown MVO, head of Transport for London which will oversee passenger services and set fares on the new line, said: “This new railway is absolutely vital to meeting the needs of the Capital’s rapidly growing population.
“The Elizabeth line will transform the way people get across our city and will enable London to continue to succeed, contributing to the economic health of the entire country. In running this important new railway we will ensure that it serves as a fitting tribute to Her Majesty the Queen.”
