Out in the sticks in Swansea I’ve seen a sign saying that train doors close 40 seconds before departure and a recent addition that access to the platforms will be stopped another minute (I think) before that. Certainly annoying to be so the ticket barriers 2 minutes before departure and watch the train sit for two minutes before leaving when you could have easily got on…
All just shows how unfriendly the system can be for a casual or infrequent rail traveller. I can understand if say your train is scheduled to be at 12:00 the doors being shut at 12:00:40 and the train leaving at 12:00:58 but where on the ticket is it written that you can't board your departing train 3 minutes before it leaves?!
Mind you, sometimes the lack of information contributes to a poor user experience. The station cafe in Woking has had a refurb (since I last used it several years ago).
If you're sat inside, there is no visibilty of any of the departure boards from the inside as they face away from the doors (I'm sure they were double sided before they got rid of the orange LED boards), nor can you hear the tannoy from the outside, there's no clocks or train departure boards either in the cafe. I was admittedly engrossed in a good book at the time and lost track of time a little, and missed my train.
Not everyone is glued permanently to their phone, and it seems whoever oversaw this refurb missed this point entirely.
Train information should be available to all users of the service, without the reliance or need to have any devices. I would have expected a departure screen to be placed inside it, maybe even a small low level tannoy inside to relay the annoucements from the platform.
