This locomotive type has been familiar to many railroad fans mostly since the class I K, road number 54, was built new in 2009. Yet the first of these locomotives was delivered as far back as 140 years ago – in 1881, in a marriage of the construction of narrow gauge railways in Saxony. There was hardly a route on which one of the 44 locomotives built was not in service. The output of 120 horsepower and the maximum speed of 30 km/h / 19 mph seem modest today, but these approximately 16 metric ton locomotives were enough for all of the demands of that time. After World War I, 27 came to the DRG, but they were then retired in the mid-Twenties.
