Gölsdorf-Senior's exceptional construction from the year 1885 for express trains on the lines of the Südbahn (Southern Railway). At the turn of the century, 12 of the class were to be found in Maribor, and 8 more in Trieste.
After 1918, 16 locomotives remained in the SHS state, hauling trains from Maribor to Ljubljana, Postojna, Prevalje, and Zagreb. By 1927, almost all were scrapped except for two, which became JDŽ 103-001 and 103-002. Because of their great historical importance, this specific unit (No. 406) from the GKB (Graz-Köflacher Eisenbahn) was acquired for our museum collection.
