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?

Several places. The layout tables in CULG show them.

That would be because they're not vertically aligned there.

[I ought to find a notation for that sort of vertically staggered
layout.]

However, other people answered Annabel's query "yes". So how exactly
*are* they aligned?

One is above the other, and where you normally enter the platforms from
the side passage it feels as if one is directly above the other.
However, one or both of the platforms has a curve [1] and so it's quite
conceivable that they aren't totally one above the other for the whole
length.

So it really comes down to what "vertically aligned" means.

[1] I'm pretty sure the northbound bends significantly anticlockwise.

[1] I'm pretty sure the northbound bends significantly anticlockwise.

It [NB] is straight on the entrance to Warty-loo until approximately
half-way down, then it swings left towards the tunnel mouth. The SB is not
*directly* beneath the NB, but slightly offset - and takes more of an arc -
until roughly the front third of the train is "straight", the rear
two-thirds are "bent"

This is from daily personal observations only - and I'm willing to be
corrected

That's a relief!! If it didn't there'd be a right mess!

I finally had a chance to check yesterday. To the best of my ability to
judge, they are *not* aligned vertically; rather, the passageways to the
northbound platforms pass under the southbound. In other words, the
layout is like this from the (south) side:

______
/ \
/ \
/ SB \______
______ \ \
/ \ \ P __\____
/ \ \_____________/
/ NB \_____________/\ S
\ \______
\ P /
\________________________/

NB and SB are the platform tunnels, P are linking passageways, and S are
stairways - up to the southbound and down to the northbound. The two
passageways are not vertically aligned; at each place, the lower (NB)
ones are south of the upper (SB) ones.
