The Ausserfern Railway is a cross-border railway line in the German state of Bavaria and the Austrian state of Tyrol. The single-tracked branch line starts from Kempten in Germany, before crossing into Austria just after passing through Pfronten. It then transits the Außerfern area around Reutte, before passing back into Germany in order to terminate at Garmisch-Partenkirchen.

Kempten (Allgäu) Hauptbahnhof is a railway station in Kempten in the German state of Bavaria. It is the most important station of Kempten and a hub for the Neu-Ulm–Kempten railway, the Buchloe–Lindau railway and the Ausserfern Railway. The original Kempten station was built in 1852 as a terminal station near the centre of town and was replaced by a through station in 1969.
