Depth of London Underground stations (updated to 2024)

The request was refused by Transport for London.

Dear Transport for London,

Under the Freedom of Information Act 2000, could you please supply me with a spreadsheet containing information regarding the depth of Transport for London stations in London.
Specifically I would like a list of all the stations on the 'tube' map with the depth (measured in metres relative to sea level) of each line that runs through that station. Please include Elizabeth Line stations, and the Dockland Light Railway stations.

Yours faithfully,
Kenneth Field

FOI, Transport for London
