Could anyone please suggest me the best available train lines and prices? I was looking for the trains from Budapest to Warsaw, but haven't find connections between Warsaw and Wroclaw, but I'm intended to visit both cities in the beginning of September (maybe on the 2nd week of Sep.).
I really need help!
Try Deutsche Bahn.The Germans have written all the connections in Europe.

If you dislike the Germans,try the czech portal Ceske Drahy.

If you want to stay faithful to Poland,there is the polish site PKP.
