I was looking at the map. Apparently, unless I'm readnig wrong, the line is
in Z3 from Kew to South Action, then a one stop venture into Z2 for Acton
Central, then back to Z3 for one stop (Willseden), then back and forth!

Why not make the line an exception and allow Z2 and Z3 tickets (like, for
example, Tramlink)?

Am I missing something?

Yes. The boundary zig-zags across that line *deliberately* to stop you
being able to go from Acton to Stratford (almost) on a Z2 ticket.

That explains Hampstead Heath, but not Acton Central or Willesden Junction
- having either of those in the 'right' zone would only extend the longest
one-zone journey by two stops. And hey, you can do the whole thing on a
Z23 ticket! Well, from Kew Gardens, anyway.

Zonal systems are still intended to make the cost of a journey be based
on the distance you travel. For a network of radial lines, concentric
zones work quite well, but an orbital line like the NLL breaks that
model. Hence the change to the boundaries.

I'd wondered if that was the case, but it just seemed too silly. Surely
the whole *point* of orbital lines is to encourage journeys like that; if
i have to pay for two zones to get from Acton to the east end, i might as
well take the Central line! And yes, Z12 is more expensive than Z23, but
it's also a lot faster.
