In the genus XVIII which ranked Grand Duchy of Mecklenburg Friedrich-Franz Railway two of the Doberan-Heiligendamm Railway , a narrow gauge locomotives acquired (DHE).
With the opening of the 6.6 km long railway line from Doberan to Heiligendamm , DHE acquired two tram locomotives . Especially the longer drive through the city in Doberan made the acquisition of such machines sensible. The locomotives were given the numbers 1 and 2. When they were nationalized in 1890, they were given the numbers 1001 and 1002. It soon became apparent that the locomotives could not cope with the increased traffic. The locomotives could only pull a three-car train. In 1891 and 1898, for example, the class XIX locomotives were procured. The tram locomotives were retired in 1916.
Constructive details
The vehicles, constructed as box locomotives, had an external sheet metal frame in which the water tank was arranged in the middle. The two wet steam engines were inside, the inclined cylinders acted on the rear coupling axle. The entire landing gear was covered. Leaf springs were installed over the axle bearings for cushioning. The kettle was arranged horizontally. The fire hole was on the right side. In order to keep the nuisance during the passage through Doberan low, the exhaust steam was led through a tubular exhaust steam condenser on the roof. The driver's cab was located on the right-hand side and could be used for driving forwards and backwards due to the good visibility. The joy control with crossed eccentric rods was reversed with a lever.
