The steam locomotives of Südbahn Class 23 (old) were goods train engines worked by the Austrian Southern Railway (österreichische Südbahn).

History

The precursors to the Austrian Southern Railway had a very disparate fleet of goods locomotives. The Southern Railway therefore had a six-coupled freight locomotive developed which was based the French Bourbonnais prototype. This series was initially given the designation 23, but was reclassified to 29 in 1864. The Lokomotivfabrik der StEG engine works delivered 20 units in 1860, which proved themselves so well that a total of 205 were built up to 1872 by this factory along with the Wiener Neustädter Lokomotivfabrik and Maschinenfabrik Esslingen.

In the course of time there were naturally several modifications: in 1861 to the driver's cab, in the 1880s a vacuum brake with sound absorbers, new boilers, etc...

After nationalisation in 1924 the Federal Railway of Austria (BBÖ) took over 47 units, that were grouped into BBÖ Class 49. Yugoslavia designated the locomotives that it received as JŽ 124. In Hungary they became MÁV 332 and in Italy FS 193.

After the Second World War a few engines, classified by the Deutsche Reichsbahn as DRG 53.7111–7116, remained in Austria. Of these, the ÖBB only took over number 153.7114 but withdrew her in 1953.

During the 1920s the BBÖ sold several engines to the GKB. One of them, number GKB 671, is still working today, albeit with some small modifications such as compressed-air brakes thanks to the work of the Steirischen Eisenbahnfreunde (Styrian Railway Society). Built in 1860, the Austrian-made Südbahn Class 23 (old) locomotive on the Graz-Köflach railway (GKB), is the longest serving steam engine in the world. It is frequently on duty and is used to haul steam specials.
