The U4 is a line of the Berlin U-Bahn in Germany that is the shortest in Berlin's U-Bahn system, with a length of 2.86 kilometres (1.78 mi).[2] Opened in 1910, the U4 serves five stations, all of which are step-free: it is also the only subway line in Berlin to have never been extended and the only one to have no night service on weekends.

In 1903, Schöneberg, an independent city that as south-west of the municipal limits of Berlin, planned to develop an underground railway line to improve public transportation. As the line promised less profit for private investors (all Berlin U-Bahn lines had until then been built with private capital), negotiations with the Berliner Hochbahngesellschaft (Berlin Elevated Railway Company, the operator of Berlin U-Bahn) were unsuccessful.

That made Schöneberg start to build the line itself on 8 December 1908. Two years later, the construction was finished, and on 1 December 1910, the line was put into operation. Although Schöneberg owned the track, upon the line's opening, the city handed operations over to the Hochbahngesellschaft.
