If you like vintage vehicles, don't miss the excellent collection of old trams at Dortmund's Local Transport Museum, housed in Mooskamp Station. 

The oldest of the trams included in these fascinating displays of the city's century-old transit system date back to the early 1900s. 

From Dortmund, these old trams headed deep into the Rhur Valley, carrying workers to the region's mines, coke plants, and steelworks.

Also of interest is the Motor Car Museum, home to a collection of fine vintage vehicles, including Jaguars and Ferraris, plus displays relating to the development of Germany's auto industry.
