Looking at booking a ticket from Prague to Oswiecim on EC115 (the 1024 departure). I'm planning on travelling in first class as tickets aren't that expensive over there on the whole but it seems like the CD website won't sell them? It has the "check price" message. Meanwhile the same train on the same date it is happily selling standard class tickets (so it's not that the train isn't open for booking)! Any one have any ideas why this might be the case? Or any work arounds!?
