The deepest tube line in the London Underground network is the Northern line.
The Northern line is renowned for having the deepest stations, with its tunnels often running significantly further below ground to navigate beneath existing infrastructure and geological challenges. This makes it a crucial part of London's transport system, albeit one that requires the longest escalators and deepest lifts for passenger access.
The Northern Line's Deepest Points
The Northern line's impressive depth is evident at several key locations:
- Hampstead Station: This station, located on the Edgware branch of the Northern line, holds the record for the deepest station on the entire London Underground network. It is an extraordinary 58.5 metres (192 feet) below street level. Accessing the platforms requires passengers to descend using some of the longest and fastest lifts on the Underground, a journey that truly conveys its subterranean nature.

- Bank Station (DLR Concourse): Even in the bustling heart of Central London, the Northern line maintains its reputation for deep infrastructure. The DLR concourse at Bank station, a major interchange where the Northern line connects with several other lines and the DLR, is another significant deep point. This section is 41.4 metres (136 feet) below street level, highlighting the complex engineering required to build and maintain such a vital transport hub in a densely developed area.
These depths underscore the engineering marvel that is the London Underground, particularly the Northern line, which tunnels far beneath the city's foundations.
