Also in the same area and little known - the Tower (of London) subway, and also parts of the City and South London Railway Thames tunnel still exist that terminated at King William Street https://www.ianvisits.co.uk/articles/rare-film-from-inside-the-tower-subway-tunnel-61318/ https://www.ianvisits.co.uk/articles/rare-film-from-inside-t... https://www.ltmuseum.co.uk/collections/stories/engineering/james-greathead-and-tunnels-under-london https://www.ltmuseum.co.uk/collections/stories/engineering/j... https://en.wikipedia.org/wiki/City_and_South_London_Railway https://en.wikipedia.org/wiki/City_and_South_London_Railway

That is very cool. I didn't know about this. I like walking through the Greenwich Foot Tunnel; while not as old as the Tower of London Subway, it is very old, and it's wild for me to walk under the Thames.

  A few years back (probably more like a decade now) they closed the London Overground for engineers works over a May Bank Holiday weekend, and opened up the Thames Tunnel for visitors - https://en.wikipedia.org/wiki/Thames_Tunnel https://en.wikipedia.org/wiki/Thames_Tunnel - that is to say the original Mark Brunel tunnel from 1843, original a foot passage, but now a part of the London Overground network. I was lucky enough to attend. It was an interesting experience - from what I recall a lot of the original ornamentation has been lost, but there are some preserved sections.

    They did it this year (or the end of last year maybe) as well :)

  There's more about the City + South London tunnels, but the best I can find at the moment is this: > The original running tunnels north of Borough station remain, although when the Jubilee line extension was built in the late 1990s, the old southbound tunnel was cut through as part of the construction works at London Bridge station in order to provide the lift shaft situated at the south end of the Northern line platforms. These running tunnels are now used as a ventilation shaft for the station and the openings for several adits to the old running tunnels can be seen in the roofs of the Northern line platform tunnels and in the central concourse between them. A construction shaft between London Bridge and King William Street, beneath Old Swan Wharf, now functions as a pump shaft for the disused sections of the running tunnels. It is no longer possible to walk through between the two stations as the old C&SLR running tunnels have been blocked off with concrete bulkheads on both sides of the Thames. The tunnels were further severed by upgrades to Bank station, as the construction shaft for the new Northern line tunnel, located in Arthur Street, cuts straight through the approach tunnel to King William Street station, with the station site itself linked to the new tunnel via a ventilation adit.[4] https://en.wikipedia.org/wiki/King_William_Street_tube_station https://en.wikipedia.org/wiki/King_William_Street_tube_stati... IIRC there's also some other "tunnels" under the Thames around the London Bridge area that are old Victorian pneumatic pipes to deliver mail+parcels.
