The Prussian G 12 CFOA-type represented a series of German 2-10-0 steam locomotives operated by the Prussian state railways. This class was initially commissioned by the Ottoman Empire Ministry of War, with fifteen units planned for deployment on the Chemins de fer Ottomans d'Anatolie (CFOA). Due to wartime disruptions, only five locomotives were delivered at first by Henschel & Son to CFOA. With the customer's approval, another five units were allocated to the German Military Railways and assigned to the Military Directorate General in Brussels (Militär-Generaldirektionsbezirk Brüssel) under G 12 numbers ranging from 5551 to 5555. To compensate for this, Henschel supplied an additional five locomotives to CFOA in 1918. The final five units originally ordered by the Ottoman Empire were never produced.

In contrast to the subsequent Prussian G 12, the CFOA model featured distinct dimensions: a larger boiler equipped with a radially-stayed firebox (as opposed to the G 12's Belpaire firebox), along with smaller cylinders and driving wheels.

Following World War I, only unit No. 5553 remained within Germany and was reclassified as 58 1001 by the Deutsche Reichsbahn in 1925 before its retirement in 1931. The other four locomotives were surrendered to Allied powers under the terms of the Treaty of Versailles. Locomotive No. 5554 was transferred to Chemins de fer de l'Est, receiving number 5015, but was withdrawn shortly after World War II due to being returned from Germany in an unserviceable state. The remaining trio was handed over to the Belgian State Railways, classified as Type 92 (numbers 9251, 9253, and 9255), before being sold in 1927 to Luxembourg’s Société Luxembourgeoise des Minières et Chemins de Fer Prince Henri (Prince Henry Railway and Mining Company), where they were designated as class O'.

During the German occupation of Luxembourg in World War II, these three locomotives were incorporated into the Reichsbahn fleet as numbers 58 601 through 58 603. After the war, ownership transferred to Luxembourg’s newly established national railway, Société Nationale des Chemins de Fer Luxembourgeois (CFL), which absorbed the Prince Henry Railway and its rolling stock; these engines were then reclassified as 53. The last locomotive of this group was retired from CFL service in 1957.

The ten units delivered to CFOA were subsequently absorbed by Turkey’s state railway system, Turkish State Railways (Türkiye Cumhuriyeti Devlet Demiryolları or TCDD). These locomotives remained operational into the early 1950s before being withdrawn from service around that time.Template:Sfnb
