Berlin U-Bahn

The Berlin U-Bahn (short for Untergrundbahn, meaning "underground railway") is a rapid transit railway in Berlin, the capital 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, it serves as the main means of transport in the capital. In addition, a tram network operates in the eastern parts of the city.

Opened in 1902, the U-Bahn serves 170 stations spread across ten lines, with a total track length of 151.7 kilometres (94.3 mi), about 80% of which is underground. Trains run every two to five minutes during peak hours, every five minutes for the rest of the day and every ten minutes in the evening. Over the course of a year, U-Bahn trains travel 132 million km (82.0 million mi), and carry over 400 million passengers. In 2012, 507.3 million passengers rode the U-Bahn. The entire system is maintained and operated by the Berliner Verkehrsbetriebe, commonly known as the BVG.
