Elizabeth Line - Elizabeth Line Construction - B

• Work began on 15 May 2009, when piling works started at the future Canary Wharf station.
• Boring of the railway tunnels was officially completed in June 2015.
• Installation of the track was completed in September 2017.
• The European Train Control System (ETCS) signalling was scheduled to be tested in the Heathrow tunnels over the winter of 2017–2018.
• At the end of August 2018, four months before the scheduled opening of the core section of the line, it was announced that completion was delayed and that the line would not open before autumn 2019. After multiple delays, in August 2020 Crossrail announced that the central section would be ready to open "in the first half of 2022".
• In May 2021, trial running commenced.
• On 17 May 2022, the line was officially opened by Queen Elizabeth II in honour of her Platinum Jubilee. She was not scheduled to attend the event, but decided to attend with her son, Prince Edward, to unveil the plaque commemorating the official opening.
