The Austrian steam locomotive class, the kkStB Class 112 was an express train tank engine operated by the Imperial Austrian State Railways (kaiserlich-königliche österreichische Staatsbahnen or kkStB).

In order for the kkStB to provide a fast feeder service to express train stations, a requirement arose for small, fast locomotives. Karl Gölsdorf designed Class 112 for this purpose. The engines were well built, enabled a top speed of 100 km/h to be attained for short periods of time and could haul 100 tonnes continuously at 80 km/h. On their deliver in 1907 by Krauss in Linz the two engines were fitted with a small smokebox superheater, that was later removed.

The small locomotives were initially used to haul newspaper trains between Vienna and Linz. Later they hauled the shuttle (Pendler) between Hütteldorf and Unterpurkersdorf, a connecting line to the Vienna Stadtbahn, where they travelled in the centre of the train.

Number 112.02 was retired in 1937, whilst 112.01 went into the Deutsche Reichsbahn as number 69 011 where it was withdrawn from service in 1942.
