The blind leading the blind

No doubt Third Rate Western have spent a lot of money on the braille versions of their highly entertaining safety instructions and have thus been able to tick some sort of discrimination compliance box.

But the announcements on leaving every, and I mean every, station confuse me. The train manager (or "guard" as they used to be known) always say:

The safety information is also available in braille format; please see the train manager for a copy.

See the train manager for a braille copy of the information? But, anyone needing the braille version can't see, surely? So how are they going to find the train manager?

Has anyone ever requested the braille information cards? Actually, has anyone ever read the normal safety information for that matter?
