#CrossBorderRail challenge: not sure what's going on on the Balkan re in Greece, but I am having troubles to find any connections from #Athens (or take Thessaloniki directly) to Rijeka (or again just take #Zagreb). Would love to do that journey over 3 days after Easter to see a bit of the countries, if needed even with a short stretch by bus if there's no train. The common sites provide no help (rome2rio, rail.cc, googlemaps), are all #trains gone? Quite annoying... cc @jon
