Berlin Underground

Berlin Underground refers to the extensive network of subterranean rail and transit tunnels beneath Berlin, primarily comprising the U-Bahn (urban subway) and portions of the S-Bahn (suburban trains). These underground systems facilitate efficient transportation across the city, allowing residents and visitors to navigate quickly around Berlin's neighborhoods while avoiding surface traffic. Constructed over the past century, the network includes multiple lines, complex stations, and some historical tunnels from Cold War-era divisions. The Berlin Underground is integral to the city’s public transit infrastructure, supporting daily mobility and connecting diverse communities seamlessly beneath the city's surface.
