After the takeover of the BLE by the Deutsche Reichsbahn in 1938, the engine was given the running number 79 001, re-using a number previously given to a Saxon XV HTV that had been retired in 1933.
The running number 79 001 was allocated in 1951 to the former French locomotive, 1-242.TA.602, which had ended up in German hands after the war.
