Underground lines by their geographic direction;

First, try defining up/down on the Circle Line.

Try defining north/south/east/west on the Circle Line. ;-)

We don't for internal use.

We use 'inner' and 'outer'

When you do track acusotmoised etc courses they tell you 2 acronyms
WIND and OUSE where rule specifics apply to one direction or the

WIND = westbound inner northbound down

OUSE = outer up southbound eastbound

None of this helps customers of course.
