Lahntalbahn

The Lahntal railway or Lahn Valley Railway is a railway line between Niederlahnstein in the German state of Rhineland-Palatinate to Wetzlar in Hesse, partly following the Lahn valley (Lahntal). Its western terminus was originally in Oberlahnstein. Trains now mostly operate between Koblenz and Gießen. The line was opened by the Nassau Rhine and Lahn Railway Company and the Nassau State Railway between 1858 and 1863 and is one of the oldest railways in Germany.
