Is First Class being downgraded?
Yeah, generally, more so in some areas than others (with some selectively used data to show that things are getting much worse or slightly better).
Is that a bad thing?
Probably not, given demands being made on the network.
The problem is that some people want the railway to give up half a coach to a buffet and another half a coach to "restaurant" seats as well as a couple of First Class coaches on Long Distance High Speed, because this is the kind of thing that BR had in the '80s and it's nice to have on an annual holiday to Cornwall.
Meanwhile, we are struggling to accommodate Standard Class passengers, and giving all of that space to non-Standard seating (First Class/ Buffet/ Restaurant) can seem a luxury.
Demands change. HSTs were built in the 1970s anticipating that kind of market (when there were few pubic places to eat - e.g. pubs shut in the afternoon and didn't sell much more than pork scratchings).
Now, with lots of alternatives (both at stations and elsewhere) the idea of giving up
lots of space on a train to store/serve food seems a bit OTT on modern trains designed to last until the 2040/2050s.
Personally, as someone who pays (full price) for his own tickets, i don't bother with First Class. But some people will shell out an extra tenner for the sake of a "free" cup of coffee and bit of shortbread, so good luck if they want to subsidise the rest of us.
The question is more a case of "does a First Class seat bring in more revenue over the week than a Standard Class one does (given that First Class demand tends to be more specific to certain times, it requires additional members of staff to dish out the "freebies", there are generally fewer seats per carriage, a lot of First Class tickets are discounted anyway)". If a Standard Class carriage is expected to bring in a few thousand pounds of revenue over a typical week then as long as First Class ones pulling their weight too then fair enough.
But if it's a train like a four/five coach EMT 222, where us plebs are stood in Standard whilst First Class has a carriage too many then I'm less convinced.
Remarkable how a thread about blinds can turn into yet another thread about seats.
