Building the Elizabeth Line


allIt took nearly 40 years between the first official proposal for an east-west “Crossrail” route in London and the start of construction work that would become the Elizabeth Line. After opposition and political struggles over who should pay for such an ambitious project, actual physical labor on the ground and underground will take a relatively short 13 years.

The demanding engineering feat quickly captured the public’s imagination. It was mostly positive. The first official construction work was done in May 2009 at Canary Wharf when stakes were ground and excavation work began on one of the first massive box stations. The demolition of the Astoria music venue in the heart of the West End became less popular as Tottenham Court Road was cleared for redevelopment.

Even at that point, the future of Crossrail was not secure. However, the following year’s election of a Conservative-led coalition declaring austerity cut the budget by just over £15 billion. Infrastructure spending was considered largely acceptable by successive prime ministers and by 2012 the most significant part of the work, the tunneling of the central section below the capital, began.

This work was done with machines made in Germany but with British names, each costing an estimated £10 million. Companies like Phyllis and Victoria drilled and built concrete tunnels with millimeter precision through a maze of railroad tracks by teams of workers behind machine heads, rather than giant drills like high-tech factories weighing nearly 1,000 tons. Lines and utilities that already occupy London’s clay and chalk.

Between 2012 and 2015, eight machines cut 13 miles of wide tunnels for future tracks, moving approximately 6 million tonnes of soil. About half of that was transported to Walash Island off the coast of Essex, creating a new wetland reserve for birds.

Even greater numbers of workers have been employed to build adjacent tunnels for sidewalks and stations, to sculpt new connections and then pour concrete, or to reopen old tunnels such as the Connaught Tunnel.

Closer to the surface, archaeologists have dug up station developments such as Farringdon and uncovered artifacts from a time when London was in greater jeopardy. The bodies of dozens of plague victims have been found on Liverpool Street and Charterhouse Square.

If there was a noticeable chaos in central London, most of the work was done underground and residents knew little about the work going on around it. In the West End, a vast team of workers was excavating and developing a vast cavern just a few feet away from hundreds of thousands of tube users.

The Queen has been in business since December 2018, when the route opened to passengers in the capital.

By 2016, the Queen also visited the construction workers, as politicians lined up in hard hats for this British victory. And it was announced that when the completed project was put into operation, she would be named the Elizabeth Line after her.

The Monarch was due to open the main central area in December 2018. Ten new stations were under way in central London. Some were large enough to have a platform entrance spanning two existing metro stops.

Construction work on stations such as Canary Wharf appeared to be near complete, and in 2017 the final part of the railroad track was built. The new trains manufactured by Bombardier (now Alstom) started operating on the eastern ground in 2017 as TfL railways.

Except it wasn’t.

Some stations seemed perfect early in the process. Specifically, it covered up the problems behind it, connecting the digital signals needed to integrate three different systems. The high-end, state-of-the-art design had a level of complexity that even bosses could not fully grasp.

A substation fire at the end of 2017 was the first hint of a much bigger problem. Bond Street, which happened later, was about 18 months later than planned. But it wasn’t until the summer of 2018 that Crossrail bosses admitted they had blown away budgets and schedules just months before the official opening.

As Christian Wolmar, author of Crossrail: Whole Story, put it, stakeholders and observers like himself have been “drunk on Kool-Aid” by senior management ignoring or ignoring the matter. “My realization came when I visited Paddington in June 2018 and saw 500 people in orange clothes still working. The platform doors were nowhere to be seen, and the escalators were shattered into pieces,” he says. “The thought of being able to finish the test in six to eight weeks is amazing.”

“The railroads are fully digitized and have the most complex construction in the country. All the systems depend on each other,” says Wolmar. “They didn’t have anyone who knew how to integrate the system, they had civil engineers trying to do the job.”

For a short period of time, Crossrail lost its shine. A £15 billion railroad eventually became a £19 billion railroad, a painful increase as new delays and overspending were announced. Hopes for an opening in 2019 have turned into the possibility of a start in 2021. The boss was replaced and TfL took over the project alone.

But ahead of opening, delays and overspending (relatively trivial in the history of major infrastructure projects) start to feel like footnotes in history. Crossrail’s designers, engineers and operators have built something unprecedented in the UK. That is, a subway service where speed, comfort and accessibility will transform the passenger experience.

After the pandemic that nearly left London’s transportation system empty, the lure of faster and better travel is more important than ever to lure people back to the capital, reshape the southeast and boost the entire nation’s economy. The world may have changed tremendously since the concept of the Crossrail, but the Elizabeth route once again carries the great hopes of politicians.
