I’m not blind but this sign just makes no sense. Consider the context. You’re blind. You’re exiting the train. Do you have time to stop AT the door, search for brail signs and read them before exiting?
I’m NOT blind and I don’t have time to do this.
Unless the train is empty you’re going to get pushed out of the train with everyone else, gap or not!
Thanks NJT for the excellent placement of this sign by the door.
