Solling line crosses the A 7 autobahn, running between Hanover and Kassel. Before Northeim it runs on an embankment and crosses the Leine river, the Hanover–Würzburg high-speed line and the North–South railway (Hanoverian Southern Railway). In Northeim, it ends at the 63.951 km mark. Former branches The former Holzminden–Scherfede mainline railway (which had been built by the Bergisch-Märkische Railway Company to connect the Upper Ruhr Valley Railway and the Altenbeken–Kreiensen railway) was crossed in Wehrden. Both lines ran parallel through Wehrden station, where changing trains was possible. After World War II, a 1.1 kilometre long rail link was built to the Holzminden–Scherfede line, connecting Ottbergen and Holzminden between Wildberg bei Amelunxen (a suburb of Beverungen) junction and Steinberg junction. Already during the war, the German military feared that three bridges near Höxter, Fürstenberg and Meinbrexen would be targets of air attacks, and in 1944 it began the construction of this rail link (since the Fürstenberg bridge made the easiest crossing of the three over the Weser to maintain), which however could not be completed. These bridges were, however, by blown up German troops on 7 April 1945 during their retreat. As it was the easiest bridge to rebuild, British engineers reopened the Fürstenberg Bridge on 1 September 1946 for double-track operations and in parallel also completed the rail link. Since the track is essentially a big curve, it was called the Engländerkurve (English curve). It was closed on 11 December 1964 and subsequently dismantled. The Weser river bridges at Höxter and Wehrden were reopened on 13 December 1948. The bridge at Wehrden for the Solling railway was rebuilt with only one track and further repairs were subsequently carried out several times. At Bad Karlshafen there was a second station on the left side of the Weser on Carl's Railway (Carlbahn) to Hümme, who was not connected to the Solling Railway. The station at the Solling was therefore called Karlshafen r.U. (r.U. for rechtes Ufer, right bank), while the station on Carl's Railway was called Karlshafen l.U. (l.U. for linkes Ufer, left bank). The closed Uslar–Schönhagen (Han) railway (line number 1802; 1921/1927–1989/1990) branched off at Uslar. History The Prussian state railways commenced construction of the line on 11 November 1873, the Ertinghausen tunnel, its highest point, was pierced on 6 September 1876, and its official opening took place on 15 January 1878. In 1886 the line was duplicated. This line was
