german train map

Is there a book you can buy, that shows the regional train plan for a specific city ? I can find the Frankfurt" regionaler schienennetzplan" on google images. I would like to get the same type map for Trier and Koblenz, showing all bus and train numbers to the surrounding towns. I dont need the exact dprtr/arrv." times & dates", just the routes and train numbers. On the DB sight you have to enter month ,day, time etc. I just want to be able to look at the color coded plan and see what trains are direct and what trains are stopping at each station along the way.
