Farringdon is one of eight new underground stations being built in central London for the Elizabeth line and will be one of the key interchange stations on the new line. Upon completion, over 140 trains per hour will pass through the Farringdon interchange, making it one of Britain’s busiest stations. With Thameslink, Elizabeth line and London Underground services, it will be a key link in bringing passengers from outer London to the business hubs in the City and Canary Wharf. The station will also provide direct rail links to three of London’s five airports.
Farringdon Elizabeth line station comprises two platform tunnels, each 245m
long, between new ticket halls over 300m apart. Each ticket hall has been
designed to accommodate future oversite developments.
This paper discusses the structural engineering challenges encountered during
design and construction of the two ticket halls on constrained sites surrounded by
existing transport infrastructure, utilities and historic buildings.
