Construction work with a special machine on the Harz narrow-gauge railroads

13 March 2025, Saxony-Anhalt, Wernigerode: View of a tamping machine at an HSB level crossing. Employees of a track construction company work at a level crossing of Harzer Schmalspurbahnen GmbH in Wernigerode. Among other things, the ballast under the sleepers is being compacted with a special machine at the night construction site. HSB maintains over 100 level crossings on its track network, which are gradually being rebuilt and equipped with new signaling systems and barriers. Work on the level crossings will continue over the next few days. Photo: Matthias Bein/dpa (Photo by Matthias Bein/picture alliance via Getty Images)
