o.uk...

As for Willesden Junction, IIRC the pink validator is half-way along the
(narrow) tunnel between the two groups of platforms, so anyone who would
benefit from using the pink validator there will naturally walk past it
when changing trains.

Isn't there a second route nowadays from the north end of the footbridge (ie
turning left at the top of the P1/2/3 stairs) to the eastern end of the high
level platforms - not a lot of use if there is no pink validator in that
direction...
