On September 3, 2015, I made this photo of an interurban electric from Bonn gliding along the streets of Köln.

The Bonn and Köln tram systems are linked via interurban connections.

One hundred years ago the Bay State Electric Railway was one of the most extensive interurban electric networks in the world. Today it is all but unknown. Yet, Interurban lines survive in Germany.
