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?


They are on top of each other. The other place that I know of is Baker
Street, for both the Jub & Bakerloo, only because I use it everyday. I'm
sure ther are others - possibly Regents Park.
