Equality and Accessibility

I noticed this morning (well, I’ve noticed the first part several times, but the second part I only thought about today) that trains now have braille “text” (and as an aside, what is the name for Braille characters? Text? Characters? Signage?) around things like the “Open” and “Close” buttons on the doors, and on the toilets etc. That’s great, and it’s always good to see these things.

However, there’s no braille on the “in case of emergency” stickers at all, or on the “how to escape from this carriage” ones.

Which seems a bit odd – after all, if a carriage is in darkness, or engulfed in thick smoke, surely the ones with the advantage will be the ones who are acclimatised to not being able to see clearly?
