Ambitious Crossrail project leans on steel to boost UK transport networks

Deep below London a network of tunnels that links both new-build and renovated station infrastructure could mark a sea change for transport in the UK’s capital city and beyond. Crossrail’s ambitious work to develop the new railway to be called the Elizabeth line represents the largest current infrastructure project in Europe. Fully integrated with the city of London’s existing transport systems once completed, the line will run for more than 100km from Shenfield and Abbey Wood in the east, to Reading and Heathrow in the west.

Expected to add GBP 42 billion to the UK economy, the new line will support regeneration efforts across London, changing the way passengers navigate the city forever. And, from the digging of the tunnels, the construction and renovation of the stations, the laying of the track and the running of the trains, steel has played a vital role in this epic project.

The Elizabeth line will serve 41 stations, with 10 of these being entirely new builds. For the existing stations that will connect with the new line, 30 are undergoing works to upgrade them to handle the new model trains and the increased passenger volume.

Mr Martin Gamble is construction manager for Farringdon, an existing station in the centre of the UK capital which is in the latter stages of its renovation and will be one of the nation’s busiest once in operation. He said that “There’s about 42km of tunnels that we’ve built,including 10 brand new stations in the central area of London.”

He added that “The Elizabeth line will increase by 10% the capacity of the whole London rail network adding that the new service will handle more than 200 million passengers annually.”

In order to create the tunnels that will allow the new Elizabeth line to weave its way under the foundations of the historic buildings and existing rail lines that honeycomb London’s underground, eight steel-built tunnel boring machines have spent three years carving 42km worth of rail tunnels.

The new tunnels, which can reach depths of as much as 40 metres, represented a complex challenge for Crossrail and required sophisticated, modern engineering techniques to be completed safely and successfully.
