Yes, but only since last month. Previously certain journeys were deemed to
always be via zone 1, although it was possible to take a route without using
zone 1, using the NLL for example *So they've listened to the criticism and

But there's no sensible route from Kentish Town West to Gants Hill via
zone 1.

If I travel from South Harrow to West Harrow, I don't expect to have
to touch the interchange validator at Rayners Lane to avoid being
charged via Z1. In fact it wouldn't even occur to me to do so.

Looking at the single fare finder, it seems that the default route for
stations west of Dalston Kingsland is changing at Highbury &
Islington, Kings Cross and Bank.
