The Berlin U-Bahn is a rapid transit system in Berlin, the capital and largest city of Germany, and a major part of the city's public transport system. Together with the S-Bahn, a network of suburban train lines, and a tram network that operates mostly in the eastern parts of the city, it serves as the main means of transport in the capital.

The Berlin S-Bahn is a rapid transit railway system in and around Berlin, the capital city of Germany. It has been in operation under this name since December 1930, having been previously called the special tariff area Berliner Stadt-, Ring- und Vorortbahnen. It complements the Berlin U-Bahn and is the link to many outer-Berlin areas, such as Berlin Brandenburg Airport. As such, the Berlin S-Bahn blends elements of a commuter rail service and a rapid transit system.
