The Class 99.32 engines are standard steam locomotives (Einheitsdampflokomotiven ) in service with the Deutsche Reichsbahn in Germany. The three examples built are still working today on the Bäderbahn Molli (Molli Spa Railway ) between Bad Doberan and Kühlungsborn-West . A feature of the engines is the tapered driver's cab due to the restricted loading gauge of the upper section of the line. With a top speed of 50 km/h it is one of the fastest narrow gauge locomotive classes in the whole of Germany , however it cannot run at that speed on this particular route.
Together with the DRG Class 99.33s , they are the only steam locomotives on the Bäderbahn Molli . Because the small Wismut engines have a low tractive effort and top speed, the search for alternatives started. As a result, in 2009 a fourth Einheitslok was built in Dampflokwerk Meiningen .[1]
