A very high level of mask-wearing still on Norwich-Cambridge and Norwich-Sheringham, and indeed in Norwich itself. Oh well.
Not terribly impressed with GAs messaging either - all 5 trains I’ve been on today still have old notices up that ‘you must wear a face covering’ and the PIS on all 5 has continued to display a message that you can be fined £200 if you don’t.
Announcements from the guards have been mixed too - some seem to have got the idea of putting in an ‘if crowded’ caveat, but at least one didn’t mention that and it sounded very much like he was saying it was still required at all times (on a fairly empty train), and another implied that it was required on that specific service because the train was (fairly) busy.
Your problem of course is that no one apart from those who don't like masks is fussed. Most other people would I suggest say "who cares".
