Yesterday, following a complaint from a passenger with a First Class ticket, Thameslink were tweeting that southbound Sutton Loop services are "First Class until Blackfriars" regardless of what it says in the timetable. Now, I don't particularly want to open that can of worms but it did get me wandering if there are any real cases where a First Class becomes declassified (or reclassified) as a train makes its way on its route.
Could this ever work?
