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. The extension to Quedlinburg Rail traffic on the standard gauge Quedlinburg–Gernrode–Ballenstedt–Frose railway ended in Gernrode after a signal box fire in Ballenstedt. Deutsche Bahn saw itself as no longer able to operate the line economically and the Gernrode–Frose section was closed. The Harz Narrow Gauge Railways took over the Quedlinburg–Gernrode section and began the conversion of the around 8.5 kilometres-long section of the Selke Valley Railway to Quedlinburg to metre gauge on 18 April 2005. The railway supervisory authority of Saxony-Anhalt approved operations over the line on 17 February 2006 and it was opened on 4 March with festivities and special trains. Since various remaining works had to be carried out, only a few special trains operated until the start of scheduled passenger traffic on 26 June 2006. The 2017 timetable shows six pairs of trains a day between Gernrode and Quedlinburg, two of which are hauled by locomotives. Route From Quedlinburg, the Selke Valley Railway runs for a few kilometres parallel with the standard gauge line to Thale until the newly-laid narrow gauge track turns to the south. This is followed by the stations of Quedlinburg-Quarmbeck and Bad Suderode (both reopened in 2006), before Gernrode station is reached. Now the old route of the Magdeburg–Halberstadt Railway Company branched off towards Frose and the line continues along the original Selke Valley Railway. The line runs past the halt (Haltepunkt) of Osterteich, next to the artificial pond of the same name, and through the Ostergrund. Past the Heiliger Teich ("holy pond", an artificial pond, which was built on the site of a pond that was believed in the Middle Ages to have health-giving properties) the line climbs through Sternhaus-Haferfeld station and continues to Sternhaus-Ramberg station. Like the previous one, this is located in the middle of a forest. After Sternhaus-Ramberg station, the line descends into the valley of the Selke. This section is the steepest in the entire network of Harz narrow gauge railways. The narrow valley of the Selke is reached by Mägdesprung station. The line
