Deutsche Reichsbahn
19 vehicles - including some brand new engines - had to be handed over to France and Belgium under the terms of the Armistice; the remainder went to the Deutsche Reichsbahn who gave them operating numbers 18 401 - 18 434, 18 441 - 18 458 and 18 461 - 18 478 in 1926. The S 3/6 became especially well-known through its use as motive power for the Rheingold Express.
