Nitpick: just short of 570 km, and at least day trains are 20 minutes faster. Another 10 minutes will be cut in December, when PKP's new EU44 "Husarz" locomotives (Siemens ES64U4 = Taurus 3) will start to pull them on the whole stretch. Still, a high-speed line would make 2-2½ hours possible.

there isn't even any decent train connection from Munich to Prague any more

Are the ALEX trains that now run the (539 km) relation in six hours crap? (It's difficult to go faster though, with no electrification from Nuremberg.)
