U5 (Berlin U-Bahn)
U5 is a line on the Berlin U-Bahn. It runs from Alexanderplatz in Mitte eastwards through Friedrichshain, Lichtenberg and Friedrichsfelde, surfaces in Biesdorf-Süd to pass Kaulsdorf and Hellersdorf above ground and finally reaches city limits at Hönow.
U5 at present only connects to other U-bahn lines at its Alexanderplatz terminus, although work is ongoing to extend it across central Berlin to Berlin Hauptbahnhof, providing further U-Bahn and S-Bahn interchanges.
