After the First World War, the French ETAT received 16 examples of the Bavarian express train locomotive type S3/6. The four-cylinder locomotives were classified as 3-231 A981-996. The three-coupled locomotives, which had 1770 hp and could reach speeds of 120 km/h, were used in the south-west of France and proved very effective on express and passenger trains. During the Second World War, the German occupying forces drove the locomotives to southern Germany and returned them to scrap after the war. Since it was no longer worthwhile to restore them to working order, the SNCF scrapped the decommissioned locomotives by 1951.
