Can anyone explain which route justifies Harrow and Wealdstone to
Harrow-on-the-Hill being £1.00 at all times according to the fare
finder? Even if you go via Brondesbury post 11 November, it can't be
done without going from Zone 5 to Zone 5 via Zone 2.

Does the single fare finder work by matching up pairs of stations and
selecting a fare or by looking simply at the zones of the two
stations?



Kenton to Northwick Park is a valid "out-of-barrier" interchange, so
that is the intended route.
