I rode that train (Munich to Berlin) after I got stranded in Munich during the 2014 Bardarbunga, Iceland volcano eruption. It was kind of slow for an ICE at the time, and quite expensive (IIRC like 150 EUR in second class).
It was one of the nicest train rides I've ever taken though - you got to see so much of Germany. The onboard restaurant was awesome.
