Warburg–Sarnau railway

The Warburg–Sarnau railway is a 100.9 kilometre-long, single-track, partially disused secondary railway line in North Rhine-Westphalia and North Hesse. The middle section, Korbach–Frankenberg, is called the Untere Edertalbahn or the Nationalparkbahn and the southern section, Frankenberg–Sarnau, is called the Burgwaldbahn.

The line between Warburg and Volkmarsen, which is known as the Twistetalbahn, has been dismantled. Since the reactivation of the section between Korbach Süd and Frankenberg on 11 September 2015 there has been continuous rail traffic from Marburg to Brilon Stadt.
