A few people have mentioned that this encourages people to travel by car rather than train - and this is one of the things that bothers me about it, apart from the annoyance to me personally.
You're not going to persuade people to use public transport more, without some attention being given to the environment in which they travel. It's long been the case that one of the attractions of the private car is that you can pretty much completely isolate yourself from other humans and their annoying habits. Allowing this kind of behaviour only magnifies this difference between modes of travel.
A few comments upthread have been along the lines of, if you don't like it, drive. Well, not everyone has that option. They have to rely on public transport and why should they have to tolerate this kind of travel environment while the more privileged can enjoy the peace and quiet of their private car.
The idea of reducing the number of unnecessary tannoy announcements is welcome - and seems to recognise that noise pollution is a significant part of the passenger experience - but I'd much rather that the issue of passenger-generated noise is addressed with the greater priority.
We've had the "rail sale" with the stated aim of getting people back to using trains. But I wonder how many people, who've barely used the train in the last few years, have taken advantage of that offer, done a journey and found themselves surrounded by a cacophony of music videos, tiktok clips, youtube videos and speakerphone calls and though "nope, I'll stick with my car in future".
