there's already TLK Comenius from Bohumín to Kraków, and this is, well, OsP Comenius from Wrocław to Leszno, because Leszno is apparently associated with Comenius but this shit is getting ridiculous at this point lmao
still, EC Odra and OsP Odra are my favourite, because they both share the route between Wrocław and Zielona Góra, and are in mostly a similar time slot, so if you rely on train names only, you would be really surprised
