 Bonn Stadtbahn

The Bonn Stadtbahn ("") is a part of the local public transit system in Bonn and the surrounding Rhein-Sieg area, that also includes the Bonn Straßenbahn.Although with six actual Stadtbahn lines (as well as three tram lines) the network is relatively small, two of Bonn's Stadtbahn lines connect to the much larger Cologne Stadtbahn (and are numbered according to that system, not Bonn's).
