mgorny, Here's a fun fact about travelling from #Poznań to #Świnoujście.
Regular #PolRegio trains take roughly 5 hours and 30 minutes, and cost 46,40 PLN.
The fastest #PKP #InterCity trains take roughly 5 hours (slower: 5 h 40 min) and cost 49,70 PLN (2nd class).
However, on weekends there's an extra PolRegio "ORKAN" train that takes 4 hours and 20 minutes (!), and costs 46,20 PLN. The trick is to skip #Szczecin Główny.
