The final chapter of a long-running documentary series charting the launch of the long-delayed and congested Elizabeth Line railway will air next month.
The Fifteen Billion Pound Railway: Inside The Elizabeth Line will air on BBC Two on June 12, less than a month after the service opens.
Filmed over 10 years, the program will capture the journey of engineers, technicians and transportation personnel who came under increasing pressure to deliver the project as they faced multiple logistical challenges.
It will feature interviews with people including Crossrail’s CEO Mark Wild, chief engineer Pradeep Vasudev and train driver Emma Knowles.
The railway, which has cost at least £18.9 billion, stretches across London and the south east and is one of the most ambitious engineering feats in Britain since the time of noted architect Isambard Kingdom Brunel.
More than a million trips were made on the central section of the Elizabeth line in the five days following its opening on May 24.
About 130,000 people traveled on the service during the first few hours of service, and hundreds of transportation enthusiasts queued from the early hours to sit on the first trains.
The service will initially operate in three separate sections, which are expected to be integrated in the fall.
Rail demand has been hit by the coronavirus pandemic.
Transport for London estimates that annual passenger numbers will not reach 170 million by 2026.
Before the virus crisis, it expected the line to carry more than 200 million passengers annually.
The new central section, built by the Crossrail project, runs through tunnels from Paddington to Abbey Wood.
It will initially be closed on Sundays, except during the Platinum Jubilee weekend, to allow for further testing and software updates.
Crossrail suffered from numerous problems, including construction problems and complications in installing signaling systems.
It was set to be completed in December 2018 and had a budget of £14.8 billion in 2010.
The final total is estimated at £18.9 billion.
