InterCity and EuroCity expresses connect all the cities and towns of the area. Hourly InterCity routes run between Düsseldorf, Köln, Bonn, and Mainz, with most services extending as far south as Munich and as far north as Hamburg. German Rail Passes are valid on these and all Deutsche Bahn trains; passes come in many configurations and include Rhineland-specific bonuses like discounts on KD Rhine Line cruises. The city transportation networks of Bonn, Köln, and Düsseldorf are linked by S-bahn, regional, and local trains (for information contact the KVB).
