Restrictions during disruption when other TOCs' tickets are accepted

[GregorD]

In brief: When one TOC accepts another's this-TOC-only tickets during disruption, how are restrictions interpreted?

Here's my scenario: When Greater Anglia services between Cambridge and Liverpool Street were disrupted recently following lightning damage, First Capital Connect accepted GA-only tickets between CBG and King's Cross. I travelled on a GA Off-Peak Day Travelcard, which has no restrictions in the evening peak. In normal circumstances, the only Travelcards and Day Returns that are valid on FCC KGX-CBG services in the evening peak (as specified by the Any Permitted tickets) are Anytimes, but would my ticket have been valid on such a service? I would have thought so, but I decided not to push my luck, as GA services were running again when I returned, although FCC were still accepting GA tickets at the last report.

Slightly murkier would be the Super Off-Peak Day Travelcard (or Day Return), which is restricted in the evening, but explicitly only from LST and Stratford. Of course, this would normally cover all trains on the route, but in the above situation, would such a ticket be valid (if ungentlemanly) from KGX during the hours in which it's restricted from LST?

I don't think there is anything set in stone but I would expect restrictions to apply as if you were using the normal route, however it may just be easier to keep people moving when there is bad disruption.
