SWR guards on my morning train from Guildford to Waterloo have clearly been told they need to announce every upcoming departure from Woking for people who are changing trains to get to eg Weybridge or Walton. That's fine, it could be useful for people. But christ do they really need to go on for five minutes? Surely "change here for services to X from platform Y at ZZ:ZZ", not a full station-by-station announcement, followed by an announcement of the status of every tube line, and then two minutes about delays on the Central line "the orange one on your tube maps" due to train shortages "until a new timetable in may?" (this is all seriously what was announced, I wish I was making it up! The Central line doesn't even stop at Waterloo!)
One announcer was holding the mic too close to their mouth so the announcements were very loud. And then he told us to remember to keep the noise down in the quiet coaches, that elicited a laugh from most of the passengers!
Some of these announcements are a good idea, but badly executed imo.
