Hello, all. I am new to this forum and I'm glad to see this thread has a lot of attention.
This is an issue that both saddens and annoys me.
I am 34, therefore old enough to remember what it was like to travel on a train with no smartphones at all. I'm old enough to remember when all we had to worry about was something listening to an iPod so loudly we could hear the general music noise. Imagine, back then, if someone suggested there would be a time in the future where people were playing music from devices with no headphones at all. It would have seemed unimaginable.
I believe there was a brief window of opportunity when this behaviour could have been stamped out, and that's passed now.
As previous posters have touched on, I believe the lockdowns had a part to play. Once we were encouraged to stay apart from people, I noticed a new trend emerge: people realised they could get away with a greater level of bad behaviour in public than before. Driving got more casual. Strangers became much less likely to converse. I just wonder if, in some way, this allowed people to get away with more because they were less likely to be confronted.
Ironically, I believe the different phases of the Covid era created a sense that nobody was sure about the rules. And if people are unsure about the rules, that means there are none.
I used to love long train journeys. I used to enjoy going to gigs in far away parts of the country so I could treat myself to a nice, long train journey and read a book while I watch the towns, villages and fields go by. Now, I truly feel a sense of dread every time I step onto any railway carriage. This is what people's behaviour has done to me.
I recently emailed Greater Anglia about this but I haven't had a reply. I think this sort of thing is worth doing even if you don't get a reply. At the very least, rail operators need to know people don't like this.
