The Tyrolean State Railway built two lines, the northern one running between Innsbruck and Kufstein on the Bavarian border. Among the 26 locomotives purchased were eight Engerth-type supporting tender locomotives, which were intended for operation with freight trains. Their chassis consisted of three driving axles with a wheel diameter of 1,264 mm and a two-axle tender.

Five of the eight machines were given the names of places along the route. These were “Amras”, “Hall”, “Innsbruck”, “Kufstein” and “Martinswand”. The remaining three were called “Achensee”, “Inn” and “Tirol”. As early as 1859, just a year after the line opened, the Tyrolean State Railway was taken over by the Southern Railway. These locomotives were first renumbered as class 18 and later as class 25.
