The fleet is in much better shape(especially refurbished, compartmentless carriages - these are great at limiting antisocial behaviour), but the infrastructure is disappearing in favour of car traffic. Some cities, like Łomża, lost access to rail entirely (although IIRC it's going to be restored after an over six year hiatus). I still drive between Wrocław and Warsaw, even though I would rather travel by train, but there's no dedicated track between these cities, so it has to take a long detour, ultimately making the trip take 6h vs 4h point-to-point by train and car respectively.
