Locomotive number 6, named "Thörl", was part of the first equipment for the Thörlerbahn which opened in 1893 connecting Kapfenberg and Au-Seewiesen. The railway was operated by the Steiermärkische Landesbahnen (StLB). Between 1945 and 1950 the engine was in Stainz to work passenger service on that line. Thörl was the first steam locomotive bought by Club 760 in 1972. In 1993 the locomotive was put on display at the 100 Years of Thörlerbahn Exhibition in Kapfenberg. In 1994 it went to Czechoslovakia for general repairs then was leased to the Thörlerbahn in 1995 until its closure and return to the Taurachbahn at Mauterndorf.
