You are still fixated upon the position of the Victoria Line. What I'm
interested in is why the passageway from the Victoria to Piccadilly
doesn't emerge at the western end of the latter's platforms. And later,
the same for the Jubilee.

As I said upthread, they were almost certainly trying to avoid congestion
at the western end of the platforms as you already get queues backing up
from the escalators on to the platforms, even without mixing in all the
people heading to and from the other lines. This way, even though it
increases the walking distance for those at the western end of the trains,
is safer. And it doesn't increase the walking distance for the pax at the
eastern end of the trains. If you're at the western end of the Piccadilly
line train, just take the escalator up, and then the Victoria line
escalator down.

That doesn't explain why this is the only station on the network where
the up-and-back-down escalator workaround is required, or they worry
about mixing new and transfer passengers.

The workaround isn't 'required', it's just a handy trick I discovered
when using the station.

It is required if you want to avoid the long walk.

Incidentally, Wikipedia suggests that the direct connection between the
Picc and Vic lines was added later

The older plan I've posted a link to is annotated: "1960's plan" and I
see that the Wikipedia article doesn't have a reference for their
assertion that the link wasn't there on opening in 1969. It's possible
the link didn't open until a bit later (some of the passages at the
revised Kings Cross deep tube complex were opened in stages) but that
plan clearly says "New escalators" so is likely to be contemporary to
the opening.

, so maybe my handy trick for getting between them was actually the
only route initially. I can't remember if I discovered the shortcut
when it was the only way between them, but perhaps I did.

It's the way I've always done it, can't remember from when, but it was
definitely as an *alternative* to the long passage.

they took advantage of the disused 1906
platform exits, stairs and lift landing to do so.

They did (but I claim from when it was opened), but was it simply a cost
saving measure, or is there something at the western end of the
platforms which prevents them installing a similar set of stairs much
closer to the Victoria Line?
