Stations are not announced in the train, and the train was 40 min late, so I had to check the Google Maps to know when to get off, and at 5 a.m. that is not the mosr desirable experience. Also, my GPS was glitching and I was saved by the people in the same compartment. Were it not for them, I would have missed the stop, because the stop at Krakow was 1 minute long.
