Harzquerbahn
In 1983, the reconstruction of the Straßberg–Stiege section was approved, especially to ensure the supply of lignite from Nordhausen to the new cogeneration plant of Silberhütte. Scheduled passenger services between Hasselfelde and Gernrode were resumed on 3 June 1984. Since then, the three Harz narrow gauge lines (Selke Valley Railway, Harz Railway and Brocken Railway—Brockenbahn) have again been connected as one network, now 140 kilometres-long. On 1 February 1993, the Harz Narrow Gauge Railways ("Harzer Schmalspurbahnen GmbH", HSB) took over the Harz Railway, the Brocken Railway and the Selke Valley Railway from DR.
