[ Update: Diagram of the current closures ]
There are several other maps available, but I wanted to do something a bit more detailed and geographically accurate that could be reconciled with the actual experience of traipsing through the tunnels.
Notes, disclaimers and things learnt during this exercise:
- This was made entirely by visual observation on a handful of short visits, with no accurate charts used save an aerial photo to get the general shape right. It's entirely possible it's hilariously wrong.
- The DLR really is slightly offset from the Northern Line and not quite parallel to it as shown. It's not me making my drawing easier.
- From shallowest to deepest the levels are: Ticket halls, District/Circle Line, Waterloo & City Line, upper interchange level, Central Line, lower interchange level, Northern Line and DLR.
- The route from end to end via the DLR rather than the Northern Line isn't actually much longer, it just involves a stupidly high number of bends and transitions.
- The Waterloo & City Line platforms have a tiny newsagent hidden in a cross passage. Is it the only deep[-ish] level station so blessed?
- The complex is so vast it has a whole other tube station within its thrall (Cannon Street).
- The lift access from street to the DLR requires using three separate lifts, two of which are in the peak hours only ticket hall.
- I have no idea what shape the Bank ticket hall really is.
- For extra anorak points I've included the platform numbers and escalator numbers - I've heard the guy on the tannoy (it appears the same one works there 24/7) use the latter to refer to the escalators under repair.
