So does this mean that all the old North London Line stations are
Oystered now? Last time I transferred from the Victoria Line to the NLL
(or whatever it's called now) and got off at Camden Road, I couldn't
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.

You'll be pleased to hear however that Oyster PAYG is coming to the NLL
soon. TfL is taking control of everything currently operated by
Silverlink Metro - i.e. the NLL, the Gospel Oak to Barking line and the
Euston - Watford line [2]. TfL promise to bring Oyster PAYG to the line
as early as possible - they're taking over in November 2007.

Oyster PAYG will eventually be rolled out over the whole of the NR
network in London, but don't hold your breath - this appears like it
won't happen for a good few years yet.
