So does this mean that all the old North London Line stations are

find one.

No - the North London Line *doesn't* yet accept Oyster *Pay-as-you-go
(PAYG)* - except between Richmond and Gunnersbury, and Stratford and
Canning Town [1].

If you have a season Travelcard loaded on your Oyster card then you can
use it on the North London Line just use it as if it was a paper
Travelcard, as long as it has the right zonal validity. If you don't
have all the required zones to cover you for your journey then you need
to buy an excess fare (also called a ticket extension) from the ticket
office before you start your journey (if the ticket office isn't open
you're supposed to do this at the earliest opportunity). The Silverlink
ticket machines, in common with all other National Rail (NR) ticket
machines, unfortunately don't sell excess fares

OK. Thanks very much for that.

Let's see if I've got this straight. If I get on the Tube system
outside my travelcard zones (1 and 2),even though I've got PAYG credit
on the same Oyster, I have to remember to buy a paper ticket for the
extra zones if I'm going to get off at one of the NLL stations - even
though my extra-zonal activity is entirely on the Underground, for
which my Oyster PAYG is valid - otherwise when I next touch in the
system will spot that I have an unterminated journey from outside my
travelcard zones and assume it was four quid's worth?
