Essen Stadtbahn

The Essen Stadtbahn (German: Stadtbahn Essen) is a 19.6-kilometer (12.2 mi) light rail (Stadtbahn) network in Essen and the two neighbouring towns of Mülheim an der Ruhr and Gelsenkirchen in the German state of North Rhine Westphalia. It forms part of the Rhine-Ruhr Stadtbahn. Like the Frankfurt U-Bahn, it is a mixed system of light rail and underground railway. One of its three lines, U18, runs completely free of intersections with other traffic. The other two lines are partly tramlines and partly underground lines. The sections of tramline have only a few sections that have no intersections with road traffic. Like all urban public transport in Essen, the Essen Stadtbahn is operated by Ruhrbahn, a company owned by the Cities of Essen and Mülheim an der Ruhr. The transport companies of neighbouring municipalities are also involved with the operation of some lines under concessions.
