Because so much of the network was up the spout today, I ended up
changing at Waterloo to catch a northbound Bakerloo Line service to
Charing Cross.

Is it my imagination, or are the two tunnels one on top of the other at
Waterloo? And where else on the network does this apply?

As other posters have mentioned - lots of places! The one I'm most
familiar with is South Kensington. There seems to be a very annoying
passenger flow to/from the Piccadilly platforms there - they are both on
the right as you are descend, and you have to cut across everyone
leaving the westbound in order to get to the eastbound platforms.
