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

Preservation
Amazingly, five of them are preserved. During the 1920s the BBÖ sold several engines to the Graz-Köflacher Bahn. Three of them, built in 1860, were preserved alongside two other Class 23 :
One of them, number GKB 671, is still working today, albeit with some small modifications such as compressed-air brakesthanks tothe work of the Steirischen Eisenbahnfreunde. Built in 1860, the Austrian-made Südbahn Class 23 locomotive on the Graz-Köflach railway, is the longest serving steam engine in the world. It is frequently on duty and is used to haul steam specials.
GKB 674 ex Südbahn 674, has been preserved by the Budapest transport museum and restored with its early roofless drivers cab.
