Public transports from Prague to Wroclaw

Question

Is there shuttle or train (other than Eurolines) from Prague to Wroclaw?

It doesn't matter if it's direct or not, but I couldn't find any link for booking the train. I have to be in Wroclaw maximum at 4 o'clock,on 21st august, but Eurolines arrives too late.

Answer 1

Deutsche Bahn website finds a few connections, e.g.

Praha hl.n.      Mi, 21.08.13    ab 05:16       EX 521   Express-Zug
Pardubice hl.n.  Mi, 21.08.13    an  06:21    

 Wait time 10 Min.

Pardubice hl.n.  Mi, 21.08.13    ab 06:31       Sp 1915 R 1915   Eilzug
Wroclaw Glowny   Mi, 21.08.13    an  10:28    

There doesn't seem to be any direct train though.
