The layout of the interchange is presumably the reason why the
Victoria Line runs "wrong way" from Warren Street to Kings Cross

Correct. There wasn't room to fix it any closer.

"Right-hand running on London Transport" was discussed in "The Why
and the Wherefore" section of The Railway Magazine in January 1968
(page 61), described as a reply to J. E. Salmon - probably the first
time I saw my name in print in any railway magazine. It included a
reference to the Victoria Line, 'now under construction'.

I'm now feeling quite old!
