I recently went away to the south-west for a weekend, and spent an afternoon in the Exeter area. Having spent quite a while on SWR and GWR trains which had very few announcements (in some cases none at all), with the only annoyance being the constant "please hold the handrail and take care" (delivered by around five different automated voices) on the footbridge at St Davids, and having returned to London on a GWR service which also had very few announcements (despite having two SSOs issued and being held outside Paddington for seven minutes), it was a little bit of a shock to descend to the Elizabeth Line platforms to get a train back home, and hear more on-train announcements on that leg than I had done in the day I'd spent travelling - although I can get it as the new timetable does mean that the stopping patterns aren't what people are used to, though I did laugh at the apologetic announcement from the driver when we were waiting at Westbourne Park, which ended with the following words, delivered in a much brighter tone than before: "Hopefully, though, we'll be able to go straight through without stopping here in the next timetable in May 2023."
Not that I found the constant EL announcements annoying - I find human announcements nice to hear. But the enormous change in frequency was staggering.
