Sent in by long-time Transit Maps reader and contributor, @dars_dm, here’s a great old photo of an interactive map kiosk in the Moscow Metro. Push a button, and your route lights up! Apparently, these displays were common at many Metro stations through the early 1970s. Highly reminiscent of the Paris Metro’s plan indicateur lumineux d’itinéraires (or PILI), an example of which I featured previously.
