Perhaps (and this is not an entirely serious suggestion) we just need to
pick a pair of names which don't have any specific geographical
connotation and use those consistently along the whole line:

LU does have something: increasing and decreasing kilometrage.

(my
notation is line: kata end (determining line @ interchange
station)):

Met: Aldgate
Picc: Cockfosters (Met @ Rayners Lane)
Jubilee: Stratford (Met @ Wembley Park)
H&C: Barking (Met @ Baker Street)
District: Upminster (Picc @ Ealing Common)
Victoria: Walthamstow (Picc @ Finsbury Park)
Central: Epping (District @ Ealing Broadway)
Bakerloo: Elephant & Castle (Met @ Baker Street - weak)
Northern: Morden (Bakerloo @ Embankment - weak)

You've managed to get "kata" be the low numbered end on all of those.
The transfer points aren't all right: District gets kms from the Central
at Mile End, Bakerloo from the Jubilee at Baker Street, and Northern
from the Piccadilly via the King's Cross Loop.

W&C: Waterloo (Northern @ Bank - weak)

The low numbered end is Waterloo for no good reason.

ELL: has no parallel interchanges

The low numbered end is New Cross [Gate], taken from the District via
the St.Mary's Curve.

DLR: incoherent (District @ Bank vs Central @ Stratford)

Also Jubilee at Canning Town.

Have i missed any interchanges in the centre of town? The map doesn't show
any as parallel, but they might be in reality.

The Victoria Line is parallel to the Northern at Stockwell, the Bakerloo
at Oxford Circus, the Northern again at Warren Street, and a third time
at Euston. And sort of a fourth time at King's Cross (if you stretch the
point a bit); also the Metropolitan there.

* Stockwell and Oxford Circus have cross-platform interchange from kata
trains to ana trains facing the same way.
* Warren Street has the Victoria kata pointing the same way as the
Northern ana (both towards Euston) though on different platforms.
* Euston has cross-platform interchange from kata trains to ana trains
facing the *opposite* way.
* King's Cross has Metropolitan, Northern, and Victoria kata all facing
the same way (eastwards). Almost also the Piccadilly (if you walk in the
ana direction from the train you'll reach the escalator down to the
Northern and be facing the ana direction).

Funny how all the lines with branches have them at
the ana end.

Central Line has them at both ends.
