Did I already do this with you a week or so ago?

If not then, yes, public transport is excellent in Germany. Search for Deutsche Bahn for the trains - the website has booking/timetables in English.

I don't know Cologne or around it, but stadtplandienst.de might help you at least see where else is around Cologne (K?ln in German by the way)
