Bad Karlshafen
The line begins in the North Rhine-Westphalian district of Höxter, near Ottbergen and runs on a high embankment including a bridge over the Nethe to Amelunxen. It runs through a deep cutting to Wehrden station and then crosses the Weser river on a steel bridge and enters Lower Saxony and the district of Holzminden. The line follows the Weser upstream, passing through Lauenförde-Beverungen station and at Würgassen returns to the district of Höxter. After Würgassen it runs on a picturesque route between the Weser and the "Hanover cliffs" to the North Rhine-Westphalia–Hesse state border on the eastern outskirts of Bad Karlshafen, the northernmost city in the state, which is in the Kassel district, and on to Bad Karlshafen. Shortly after Bad Karlshafen the line runs through the Lower Saxony district of Northeim. The Wahmbeck tunnel cuts through a loop of the Weser.
