Biebermühl Railway, Pirmasens

The Biebermühl Railway —sometimes called the Moosalbbahn —is a 35.9 km long railway line from Kaiserslautern to Pirmasens in the German state of Rhineland-Palatinate, which was built between 1875 and 1913. The first section between Biebermühle and Pirmasens connected the city of Pirmasens to the railway network, which could only be achieved via a branch line due to the topography. In 1905, another branch was opened from Biebermühle to Waldfischbach, which was extended in 1913 to Kaiserslautern. It was subsequently used by long-distance services, which operated until 1990. Since then, it has been used only by local services. It is the only one of all the Palatine railway lines that were completed in the 20th century that has never been threatened with closure. ()
