I did some digging and found elsewhere (

) people with email replies from WAGN reporting that you could indeed
combine a season Zonal Travelcard and a NR season (say, Cambridge-
Oakley Park). Obviously, I've asked FCC this directly as they're now
the ones in charge (and awaiting a reply), but my reading of the NRCOC
is that it isn't valid, though my mind flip flops on this everytime I
read it.

Of course, the NCoC only set out your minimal entitlement. If a TOC
wishes to grant you additional privileges, such as using that
combination of tickets on a non-stop train, they have every right to.

"You may use two or more tickets for one journey as long as together
they
cover the entire journey and one of the following applies:
...
(c) one of the tickets is a Season Ticket (which for this purpose does
not include Season Tickets or travel passes issued on behalf of a
passenger transport executive or local authority) or a leisure travel
pass, and the other ticket(s) is/are not."

I read that as:
As long as you mix a season ticket ( Cambridge-New Barnet ) that was
issued by a TOC and something which is not a season ticket, you should
be OK on the fast trains (which incidentally sounds to me like you
could use ordinary tickets to extend your journey on fast trains).

Now, the question is thus, "is an Oyster period TC a season ticket,
and if so, is TfL a PTE?"

Somewhere in the Conditions it explicitly states that period
Travelcards *do* count as season tickets for the purpose of this rule.
