Perhaps it would be an idea to have a campaign "Don't be afraid to ask, and do help others" to encourage passengers to ask and help one another.
I can report that I have been putting this into practice, and feeling much better for doing so.
On Thursday of last week, I was on a Chiltern train from Birmingham Moor St to Marylebone, which failed at Dorridge. We're all asked to alight, and have to wait for an hour for the next one. No-one on the station; no announcements; nothing. But we are helping one another. Sitting in the waiting room, there’s an 85-year-old man on the phone to his daughter. “Does the next one stop at Princes Risborough or Haddenham & Thame Parkway?” asks the daughter (he's got the mobile on loud). I'm able to look it up and tell him “No it doesn’t”.
On the Friday, I'm at Paddington for the 18:57 back to Worcester. It’s shown as leaving from platform 2, but the train there says it’s the 19:06 to Bedwyn. The train on platform 3 is also saying it's the 19:06 to Bedwyn. A conversation with the only other passenger in coach K (First Class is very very empty); she also hopes it’s the 18:57 to Great Malvern. No internal displays, no reservations. Until a couple of minutes before departure, when we get some good
PA▸ announcements from the train manager (“this is NOT the 19:06 to Bedwyn”) and, belatedly, some internal displays and reservations.
