A number of narrow-gauge lines survive, largely as a consequence of German reunification, in the former East Germany where some of them form part of the public transport system as active commercial carriers. Most extensive of those still employing steam traction is the Harz mountain group of metre-gauge lines, the Harzer Schmalspurbahnen. Other notable lines are the Zittau–Oybin–Jonsdorf line in Saxony, the Mollibahn and the Rügensche Kleinbahn on the Isle of Rügen on the Baltic coast and the Radebeul-Radeburg line, Weisseritztalbahn in the suburbs of Dresden. Although most rely on the tourist trade, in some areas they provide significant employment as steam traction is particularly labour-intensive.
In the Western part of Germany, Selfkantbahn (close to Heinsberg near Aachen) and Brohltalbahn (Linz/Rhine) are the best known ones, offering services in summer weekends.
