If I'm traveling rom Berlin to Cologne by ICE train, how long would it take me and how much would it cost?

It will take 4 hours 21 min and cost just under 100 Euros.

Try plugging in your real travel date at the link below (german rail timetable in English) for better info.

PS Germany section is located seperately directly under Travel, do not click through to continental Europe. I guess Yahoo thinks Germany is a continent of its own.... lol
