Then there's Dartford. It's hard for customers on the 3 north Kent
parallels to get from one line to the other without going back to
Lewisham which might not be in their zone. Is it permitted to change
trains at either Dartford or Lewisham on a travelcard if you promise
not to leave the station?

An anomaly is that holders of freedom passes can use Dartford station.


I while ago, I thought I remembered (or had dreamed) a proposal or rule
change to allow people to travel through a zone without getting off
without a ticket for that zone. I wrongly thought it might be the
central zone, but I am thinking now that it must have been to do with
travelling through an outer zone.

If that rule change or proposal was true, one would be able to travel
from, say, Belvedere to Albany Park with just a zone 5 ticket.

It could still be a figment of my deranged imagination.
