Are you sure about that? I thought the usual rules concerning multiple
tickets covering a single journey (ie the train must stop at the station
where you change tickets) did not apply to the London zonal system, and
therefore 'fast' trains could be used. Or does this easement only apply to
zonal *season* tickets (ie not one day travelcards etc)?

When switching between two tickets you must travel on a train that
stops at the changeover station unless one of the tickets is a season
ticket OR both tickets are zonal tickets. A zonal ticket is one which
includes a zone boundary in some way - either for travel within a zone
or by being for travel from a zone boundary to some other point. One
Day Travelcards are zonal tickets but not season tickets. Travelcard
season tickets are both season tickets and zonal tickets. No kind of
easement is involved.
