I wasn't aware that such things existed - is that at Euston?

Sorry, I meant to say "at Euston". When the Victoria Line was built,
they arranged cross-platform interchange at Euston between
roughly-northbound Victoria and roughly-northbound Northern (Bank
branch). But the "northbound" trains at that point are actually running
east-west in opposite directions. Similarly for southbound.

An interesting intellectual exercise, but please don't get a job
in LU!

Oh, i don't think they need my skills in the
confusing-the-hell-out-of-people department.
