In what year was the Elizabeth line opened?

The Elizabeth line, also known as Crossrail, officially opened to the public on May 24, 2022. This significant infrastructure project connects several key areas from east to west London, improving transportation capacity and reducing travel times across the city.

The development of the Elizabeth line was a major event in London's transport history, reflecting years of planning and construction. The line was designed to enhance connectivity, linking areas that were previously less accessible and accommodating significant passenger numbers. It is vital for understanding modern transport developments in London.

While 2020, 2021, and 2023 are mentioned, they represent either earlier anticipated completion timelines or years when subsequent expansions or additional services might be planned but do not reflect the actual opening date of the Elizabeth line. Therefore, 2022 is the correct choice, marking the start of services on this new line.
