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.

Yes they are.

And where else on the network does this apply?

There are several on the centre portions of the Central Line.

Several places. The layout tables in CULG show them.

But not for the Bakerloo at Waterloo, they don't.

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.

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.

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