Gleisdreieck

Gleisdreieck is an elevated Berlin U-Bahn station located on a viaduct in the Kreuzberg district, and served by lines U1, U2, and U3. The U1/U3 platform is at a higher level than, and perpendicular to, that of the U2.



The station's name literally means "railway triangle," or wye in English, and marks the spot of an earlier major train hub that opened in 1902, where the three branches of the first Stammstrecke U-Bahn line from Zoologischer Garten, Potsdamer Platz and Warschauer Brücke met. A major accident at the triangle happened on 26 September 1908, when two trains collided.
