Frankfurt am Main, Germany. Rail Transit Map

Frankfurt am Main is the most populous city in the German state of Hesse. Its 778,589 inhabitants as of 2025 make it the fifth-most populous city in Germany, that forms a continuous conurbation with Offenbach am Main with population of over 2.7 million. Frankfurt is the heart of the Germany's second-largest Rhine-Main metropolitan region, which has a population of more than 5.8 million.

The city has two rapid transit systems: the U-Bahn and the S-Bahn, as well as an above-ground tram system.

Nine S-Bahn lines (S1 to S9) connect Frankfurt with the densely populated Rhine Main Region. Most routes have at least 15-minute service during the day, either by one line running every 15 minutes, or by two lines servicing one route at a 30-minute interval. Number of stations 112 (13 underground), annual ridership 150 million.

The U-Bahn has nine lines (U1 to U9). The trains that run on the U-Bahn are in fact light rail (Stadtbahn) as many lines travel along a track in the middle of the street instead of underground. The minimum service interval is 2.5 minutes. System length 64.85 km (40.3 mi), number of stations 86 (26 underground), annual ridership 125 million.

Frankfurt has ten tram lines (11, 12, 14 to 21), with trams arriving usually every 10 minutes. Many sections are served by two lines, combining to run at 5-minute intervals during rush-hour. Trams only run above ground and serve more stops than the U-Bahn or the S-Bahn. Route length 68.67 km (42.7 mi), stops 141, annual ridership 67 million.
