This trio of small articulateds originally were ordered by the Chilean State railways after a 1927 prototype had proved successful on Chile's extensive narrow-gauge system. The three that were ordered a decade later, however, could not be delivered because of the onset of World War II. Although the prototype was equipped with a Westinghouse air-brake system, the production engines used the Knorr-Bremse system. Interesting, much of the frame was riveted.
The German Army set them to work in the Heeresnbungsplatz Rehagen-Klausdorf complex as well as operating them on the Schmalspurbahn network in Mecklenburg-Pommern.
By 1944, the three engines had been dispatched to Polish railways and, after surviving the last chaotic months of World War Two in Poland, were taken in by the PKP and reclassified. Tyy 1-693 operated at the Solvay factory until sold in 1955 while the other two were discarded in 1961.
