The Gotha–Leinefelde railway connects Gotha and Leinefelde in the German state of Thuringia. It was opened in 1870 by the Thuringian Railway Company. The line is about 67.1 km long. Regional-Express line 612 services operate every two hours on the line between Göttingen and Chemnitz and Zwickau. Erfurter Bahn operates services every two hours using Regio-Shuttle diesel multiple units. The running time is 40 minutes (Regional-Express) and 65 minutes each way. It is thus part of the fastest connection from Jena, Weimar and Erfurt to Hanover.
