London Bridge during the 2019 London Marathon.

Passengers ascend and descend the deep escalator shafts of London Bridge Underground Station, one of the busiest interchanges in the capital’s rail network. Rebuilt and expanded during the Jubilee Line Extension project of the 1990s, the station’s concrete-lined tunnels and exposed mechanical framework represent a fusion of industrial engineering and modern architectural design.

At nearly 26 meters below ground, these escalators connect the Northern and Jubilee lines with the mainline concourse above, handling tens of thousands of passengers daily. The structural bracing and utilitarian lighting were deliberately retained as visual elements, emphasizing the monumental scale of London’s deep-level transport infrastructure.

London Bridge Station’s Thameslink platforms represent one of the most advanced pieces of commuter rail infrastructure in the UK, rebuilt as part of the £1 billion redevelopment completed in 2018. The redesign introduced a vast concourse beneath the platforms, new canopies, and digital passenger systems to accommodate over 50 million travelers annually.

Visible here is a Class 700 Thameslink train, part of Siemens’ Desiro City fleet, which operates high-frequency services linking Bedford, Brighton, and Cambridge through central London via the core Thameslink route. The streamlined architecture and wide canopies were engineered to handle both heavy peak-hour volumes and seamless integration between National Rail and the London Underground’s Jubilee and Northern Lines, establishing London Bridge as a key interchange in Britain’s modern rail network.
