Five years have passed since the 73-mile, high-speed, and high-capacity Crossrail project first broke ground on the central part of the line in London. More than 23 miles—nearly 90 percent—of the train tunnels have been completed and tunneling is slated for completion in spring next year. Over 10,000 people are working around the clock on Crossrail’s estimated 40 construction sites. The new east-west railway expects a daily ridership of 220,000 people.

The stunning progress images depict platform tunnels beneath various roads in London stretching from the city of Reading in the west and Abbey Wood to the East. Eight 150-meter-long thousand-tonne tunneling machines were used on Crossrail. These massive platform tunnels have been the result of the work of several hundred tunnelers working 24/7 for the past two years.
