You want to go from A to B. For example, from Gnarrenburg to Bremen Hbf. You start on Bus 640 (fare zone 355), change to Route 670 (fare zone 225) in Worpswede and travel through Lilienthal (fare zone 219) to Bremen Hbf (fare zone 100), a total of four zones = price level D. There are up to eight price levels (A to H), an individual price level I each for Bremen, Bremerhaven, Oldenburg, Delmenhorst, Nordenham and Verden and price level S for Bremen and the surrounding area. When you enter “Start” and “Destination”, the FahrPlaner automatically does everything for you.
