In 1903 Krauss Linz built the prototype light (in fact very light) locomotive for local lines, with the 0-2-0 axle arrangement, compound steam engine, mixed coal-oil firing, inner frame and Joy valve gear. Numbered 185.01 (s/n 4879) it was sold to Welser Lokalbahn, later taken over by ČSD and written off in 1922. No further orders were placed. In 1905 an enlarged version was built, fitted with larger drivers and featuring boiler pressure increase from 12 to 15 bar. Cylinder bore and piston stroke were also increased and weight in working order rose from a mere 15.7 to over 21 tonnes. This prototype (s/n 5263) was basically an experimental locomotive, intended to investigate new type of firing. Later it was numbered 86.01 and saw service with the Wiener Stadtbahn. The manufacturer hoped to attract attention of local private railways with this comparatively modern and economical engine, but only two more examples were ordered in 1908 for the Lokalbahn Krainburg-Neumarktl (today Kranj and Třzič in Slovenia). They were numbered 86.02 and 86.03 and featured coal firing only; grate was increased in area from 0.65 to 0.92 sq.m. In 1918 both were taken over by the railways of the Kingdom of Serbs, Croatians and Slovenians and later served with Yugoslavian state railways JDŽ as class 161. During the war 86.01 was transferred to Galicia and in 1918 became the property of PKP. It was considered to be of little use and withdrawn in 1924, but appeared again in the motive power types list, issued by the Ministry of Transport in 1931. The reason for this is unclear, but it seems possible that the engine was used only for auxiliary duties. It was withdrawn before 1936 and scrapped.
