@lilylunatic did you know there are PDFs with this info for every bigger stop on PKP Intercity network and it's useless on all of them because sectors aren't used at all
(i have seen people use these in paper forms on stations, as well as these screens but they are quite useless since sectors are huge and you have no idea where it will actually stop (i tried to figure out my coach in Gdańsk this way but it wasn't where i stopped)
