This class of compounds were the first de Glehn-type Ten-wheelers to go into service in all of Europe. Unlike the KPEV's experience with a later adaptation (Locobase 6458), the Baden engines satisfied requirements nicely. Adopted for Black Forest express and passenger trains, the class entered service over a 7-year period. They proved quiet and smooth-running, says Lindecke, and the de Glehn system, which allowed live-steam operation of all 4 cylinders, permitted rapid acceleration. Separate control of the LP (driving the first coupled axle) and HP cylinders (powering the second axle) meant the ability to vary horsepower according to requirements. Tests showed the ability to pull a 250-ton train on the level at 75 km/h (46.6 mph)
By the time of the DRG's formation in 1925, 35 were left as BR 38 701 to BR 38 735. They were all withdrawn by 1932.
