The line reached the Finne ridge in Herrengosserstedt and runs through the Finne Tunnel (6965 m) between Rastenberg and Bad Bibra. After a short section that includes the Saubachtal overtaking loop the line passes over the Saubach Viaduct (248 m). This is immediately followed by the Bibra Tunnel (6466 m) where the line passes below the Hermundurische Scholle plateau and comes to the surface again east of the Dissa valley. Northwest of Wetzendorf, the line crosses the valley of the Unstrut on the 2668 m-long Unstrut Viaduct. It then passes through the Osterberg Tunnel (2082 m), which ends at Kalzendorf, and the Jüdendorf overtaking loop. It now runs across the plateau of the Querfurt Plate (Querfurter Platte) and no further major engineering structures are required on the line apart from the Stöbnitz Viaduct (297 m). In Bad Lauchstädt, it passes under autobahn 38 and reaches the Dörstewitz overtaking loop.
