Shall we just plaster every available surface with safety information and play it over the PA every 15 seconds in 12 different languages then?
No, you simply put it on a card (possibly in more than one language) for people to read if they want, or ignore if they don't.
Why would you want to go to such extremes as your suggestion? (And, yes, I know you were being sarcastic - but it's actually just childish).
Maybe there's a place for it on HEX where a significant number of passengers will have never travelled on a UK train before and some may come form countries with very different safety cultures, but not on "normal" trains. Aircraft are a little more different, with their far more limited escape routes, etc.
So people on FGW are all locals and used to our trains? What an odd thing to say!
I think of an aircraft cabin as being rather similar to a train carriage actually. Long, seats on each side of an aisle.. exits at front, rear and middle (window exits on a train). Erm, besides one not taking off from the ground, can you explain why they're so different again? Okay, no oxygen masks or life jackets to worry about, but there's nothing about this in the safety card on a train is there?
Trains don't have the demonstration from train crew, and the driver/TM doesn't read out the safety instructions
I say it's a good thing to make something available, which you can happily ignore if you want (why exactly are you so angry and offended about a card in the seat pocket?) when everyone knows few people read the safety posters on the wall of a train. So, while there's a legal requirement to publish this information, most TOCs are happy to just do the bare minimum which helps no one. Rather that slag off FGW for doing it on the HSTs, why aren't we asking why other operators don't do the same?
