(Currently being updated for 2025/6) Poland's inner rail borders, created by the execution of the handover of responsibility for regional rail to the voivodeships, and also information on the state of the outer rail borders. Feel free to click on each border and read the notes, too! This map is a remix of Jon Worth's #CrossBorderRail All The Borders map (https://umap.openstreetmap.fr/en/map/crossborderrail-all-the-borders_935041), compiled by HaTetsu (https://mastodon.com.pl/@HaTetsu) and mostly up-to-date as of September 2025. It was inspired by short discussions of the problems of French rail regionalization which are in some ways even worse than Poland's despite (or because?) the operation being almost all SNCF. I swear it's not a challenge, but the borders are colored according to whether Jon's passed through there as part of the #CrossBorderRail journeys, as on the original. Lines that only existed in wartime are excluded, as may have been a couple minor ones dismantled long ago. Voivodeships and surrounding regions are represented with ISO letter codes where possible, not because they are well known, but because they are easily checked, short, and mostly unambiguous once learned - the exceptions are Czechia and Ukraine which do not use letter codes, for Czechia I used license plate codes prepended with CZ-.
