Swiss people are always efficient. Not to talk about Swiss trains, with their notorious punctuality and cleanness.
Now they are going one step further, employing useful visual representations to decorate the train! Indeed they printed the map of the train route on the tables, so passengers can entertain themselves looking at the map, learn about Swiss geography, and always know what are the next stops.
Switzerland is always ahead, so if they are using visuals on trains, I’m very confident this shows an upcoming trend!
