The non-map way of doing things would be to have lots of signs and
posters - possibly with a further highlighted mini-map - advising
passengers going between Waterloo/Embankment/Charing Cross and Euston/
KXSP to use the Bakerloo & Victoria via Oxford Circus.

Whatever happened to the "follow the green lights for Waterloo" etc.
which used to be displayed at many interchange stations?
