Nit: s/language/alphabet(?)/

Alas, there are places where I can't imagine where I saw/felt Braille labels and wouldn't know how to place a visual label so that a blind person could find it. For example, labels placed on handrails next to rail carriage entrances that indicate whether/where the toilet is in this carriage and how the carriage is divided between 1st and 2nd class seats. The way they're placed now ~forces you to touch them if you enter the carriage while and use handrails.
