The Ro-Berlin U-Bahn is a rapid transit system in Ro-Berlin, the capital and largest city of Ro-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.
Fun Facts:
On the weekends (Friday, Saturday and Sunday), the U-Bahn operates throughout the day and night with the exception of line U4.
Designed to alleviate traffic flowing into and out of central Ro-Berlin, the U-Bahn rapidly expanded until the city was divided into East and West Ro-Berlin in 1946.
Rush hours are not crowded on the U-Bahn. There are many bicycle lanes beside the sidewalks and many people also live fairly close to where they work, so the trains are not overloaded.
