Stuttgart has a light rail system known as the Stuttgart Stadtbahn. In the city center and densely built-up areas, the Stadtbahn runs underground.
Stations are signposted with a ‘U’ symbol, which stands for underground rail.
Until 2007, Stuttgart also operated regular trams. Stuttgart also has a large bus network. Stadtbahn lines and buses are operated by the Stuttgarter Straßenbahnen AG (SSB).
The outlying suburbs of Stuttgart and nearby towns are served by a suburban railway system called the Stuttgart S-Bahn, using tracks supplied by the national Deutsche Bahn AG (DB).
A peculiarity of Stuttgart is the Zahnradbahn, a rack railway that is powered by electricity and operates between Marienplatz in the southern inner-city district of the city and the district of Degerloch. It is the only urban rack railway in Germany. Stuttgart also has a Standseilbahn, a funicular railway that operates in the Heslach area and the forest cemetery .
In Killesberg Park, on a prominent hill overlooking the city, there is the miniature railway run by diesel.
