The Harz Railway or Trans-Harz Railway (German: Harzquerbahn) was formerly the main line of the Harz Narrow Gauge Railways (Harzer Schmalspurbahnen or HSB) and runs north to south right across the Harz Mountains from Wernigerode to Nordhausen. However, the tourist attraction of the Brocken, the highest mountain in the Harz, is so great that the Brocken Railway is effectively the main line today. The Trans-Harz Railway joins up with the Selke Valley Railway to Quedlinburg at Eisfelder Talmühle where all trains are organised to make good connections.
