The Baden main line (German: Badische Hauptbahn) is a German railway line that was built between 1840 and 1863. It runs through Baden, from Mannheim via Heidelberg, Karlsruhe, Offenburg, Freiburg, Basel, Waldshut, Schaffhausen and Singen to Konstanz. The Baden Mainline is 412.7 kilometres long, making it the longest route in the Deutsche Bahn network and also the oldest in southwest Germany. The section between Mannheim and Basel is the most important northern approach to the Swiss Alpine passes, whilst the section between Basel and Konstanz is only of regional significance. The stretch from Karlsruhe to Basel is also known as the Rhine Valley Railway (Rheintalbahn) and the Basel–Konstanz section as the High Rhine Railway (Hochrheinstrecke).
