Austrian Southern Railway class 1II
Austria-Hungary 1889 2 produced
The class 1II designated two light tank locomotives which were built for the line between Mödling and Laxenburg. This line went to the summer residence of the emperor and so these locomotives had the task to haul short trains with him and his entourage. Delivered in 1889, they carried the numbers 2 and 3. They had two axles of which only the second one was powered by cylinders which were placed behind the leading axle. The vacuum brake was assisted by a counter-steam brake. Between 1910 and 1915 they were replaced by the class 4II that was even older, but had a baggage compartment.
