It's a high speed train on a

BTW, if you have a choice, and you should, try to take a train that follows the Rhein for the scenery. You want to go through Mainz (the stretch of the Rhein with all the castles) and Bonn Hbf, not Bonn Siegen IIRC. The time should be about the same.
This route takes a couple of hours and is scenic. You could even do it on local/regional trains if you wanted. Just type in "koblenz" in the 'via' box on bahn to price it that way
