Looking at some of the figures, London is a prime candidate for losing those tedious carriages and running continuous waterslides instead.
Almost all of the lines are above ground, then they sleaze into tunnels in central London, and the difference between surface elevation to depth is pretty striking,
for example DLR Bank station, which is 41.4 metres below ground level and Amersham station which is 147m above sea level...
One part of this was mentioned by AfroAssault, Apr 23 2006, "High speed waterslide subway entrances/exits." but that doesn't cover the whole of the network, just entrances/exits...
After reading all of this kind of stuff I found "..{the total length of the tube lines}... was remeasured in kilometres using Ongar as the zero point". Is Ongar really that bad?
Probably the closest prior art to this idea

Minor risk with this idea of underground stations
filling up with water and everyone drowning. |

^Hmmm, tube passengers are hardy souls - Balham station 14 October 1940, a 1400 kg bomb was dropped on the station, it ruptured the water and sewage mains - only 66 died. |
