Re information, it’s worth looking at this from the other end of the telescope.
An individual traveller (and I am one!) will naturally want to know what is happening to MY train on MY route NOW.
The people in control responsible for disseminating information will have incomplete info, an evolving situation, and most importantly, potentially dozens of trains, each with hundreds of individual passengers, to communicate to. It is impossible to get the right individual message through the chain to every individual passenger. There will always be passengers who feel they have no info, or poor info, which cause them individual strife. And many will complain (rightly), often on these pages.
Meanwhile those who do get good info get to their destination relatively smoothly, but, naturally, won’t shout about it. A notable proportion will complete their journey without even realising there was a problem.
I’m in the fortunate position to have been on both ends of the telescope. Even so, I get really frustrated when info isn’t passed on, but almost every time it is because the driver / conductor / station announcer has not been given the info. Hell, I’ve even been on trains where I have realised what is happening well before the driver, and asked him/her if I can do the annoucements, and they have been more than happy to oblige.
