The steam locomotive was built in 1926 by the firm Henschel und Sohn in Kassel and was delivered through the intermediary agency Ferrovia Radotín. The pressure tests took place 8. 6. 1926 in Oščadnica and the technical and police tests 30. 6. 1926 on the track Chmúra – Erdútka (Oravská Lesná). Originaly she was named ”Horno I.” and as the most powerful engine of the railway it was assigned to the traffic on the connecting line transporting loaded timber tracks over the Beskyd Pass. She was operating until the closing of the KOLR. After the closing of the railway she was stabled as non-operational in the area of the former depot in Zákamenné, in 1988 she was deposited in the steam plant at Tanečník. There was an attempt in the 1980s to repair the engine´s steamer in Námestovo, where on inspection the damaga proved to be bigger than expected and the repair was not realized. From the beginning of the nineties she has been deposited on a turn-out track in the Chmúra station where, because of lack of means for preservation, she yielded for years to irreversible corrosion, alongside with the Krauss Maffei 15791/1940 engine. In August 2000 this situation has been at least partially solved by transferring the engine under the provisory shed in the Chmúra station and by planning her preservation for 2001.
