The Husum–Kiel railway is a main line railway in the German state of Schleswig-Holstein. While the central section of the line, which is shared with the Neumünster–Flensburg line, has two tracks and is electrified, its western and eastern sections are single track and are not electrified. It connects the cities of Husum and Kiel via Rendsburg and serves as an important east-west rail axis between the North Sea and the Baltic Sea.
