operations Up to six pairs of trains run daily to the top of the Brocken during the winter. Of those, four start and end in Wernigerode. During the summer, services are increased to eleven pairs of trains daily. The fastest train takes 49 minutes to reach the summit. The Brocken Railway is the only HSB line whose regular services are exclusively hauled by steam locomotives (specials are also hauled by diesel railbuses and diesel engines of Class 199.8, the latter for clearing snow).
