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?

You'll find instances of this on most LU tube lines.

On the DLR, using the same sort of technology present in the Tardis,
presumably, there's at least one station where the two lines and their
respective platforms are exactly spatially coincident, only temporally out
of phase by several minutes.
