Cologne (Koln)
light rail subway

This Bavarian town's light rail network has 11 lines and 192.2 km of track. It connects with the light rail system of nearby Bonn via line 18 and 16, and is sometimes refered to as Statdtbahn Rhein-Seig. Both Bonn's and Cologne's transit authrities are under the Vehrkersverbund Rhein-Seig, which serves mostly as an integration entity. Cologne's statdtbahn network is the largest in Germany (excluding Karlsruhe's tram-train network).

According to lrta.org, the first electric tramway opened in 1881. It's first subway section opened in 1968, and a new 3 km subway is scheduled to open in 2010. The lines operate in a combination of street running and private right of way with standard modern light rail stations. Most of the system has been rebuilt to accomodate grade seperated mode.
