@blotosmetek @grootinside @cstross Hmmm, on second thought, I think I get it now. This map is a few years out of date. Green doesn't mark reopened lines, either. I think it marks (some) lines without regular regional service, usually with just one or two IC pairs, or maybe seasonal service. Red marks lines with no passenger service at all. And it doesn't show any lines built since the end of the 80s iirc. (There's not many of them, pretty much all airport links and tiny connections between existing lines allowing avoiding long breaks for moving the locomotive to the other end of the train at certain junction stations)
Rail *is* improving in Poland - not equally everywhere, but the renaissance is real, lines are getting reopened, trains are more punctual than they used to be, there's more modern rolling stock (emphasis on *more*, it's hardly everywhere and PKP Intercity carriage trains certainly can sometimes feel like they're lagging behind - and other times really lag behind) and ridership is rising
