Yes, these were the German Br.52 Kriegsloks equipped with condensing tenders and equipment for service on the Eastern Front, as Hitler invaded the Soviet Union.
Some survived after the war, being used as stationary steam engines, especially in the now former East Germany.
One 52.Kon was taken by the US Army back to the US with a few other Reichsbahn engines (including the unique streamliner 19.1001) for further study and display, before being cut up for scrap when there was no further use for them.
