This is the AEG interior indicator, used on 90s and 2000s trams.
The original font "Innenanzeige1" by @aljodo was modded to support Polish and Czech letters.
This is a clone of Innenanzeige1LED lettering used by PTV (Public Transport Victoria) on the SmartBus boards for "how long until the next bus" information. I ride the bus to work each day, so these are pretty familiar, but I still had to guess some of them. I've left out some glyphs where they're just not useful (e.g. comma or quotation marks).
