I can't see how they can make the restrictions stick in the case of trains
which call at stations like Alexandria Palace or Mill Hill Broadway. CDRs
are val;id for break of journey, and ODTCs are valid for multiple journeys.
Journeys from Central London to these stations (or others in Zone C on the
leaflet) are unrestricted in the evening peak, as aqre journeys from Zone C
northwards - all you have to do is to break your journey at a Zone C
station. Does it count as break of journey if you resume your journey on the
same train? Alter4natively you could of course split tickets at a Zone C
station, though your train both ways would have to call at the station where
you split your ticket.

That would be hugely inconvenient if you live north of about Welwyn
GC, as you'd have to get an all-stations service at least as far as
Potters Bar. It could (at a guess) add 30-60 minutes to your journey
(your usual train could be first stop Letchworth or St Neots).
