That's where Japan is generally brilliant with trains-- depending on the number of carriages of a train, there are signs informing you of where to stand (particularly important for reserved seat-trains, or for Green Cars (the more expensive ones). In the Tokyo Metro (and TOEI), other signs tell you which carriage is closest to ___ exit of that particular station.
Then, you have the tactile paving throughout Japan (straight lines until you hit a curb/a change in the sidewalk, then they become bumps).
These things might exist elsewhere, but I'm much more familiar with Japan.
