Novelty 2025: After the Second World War, six examples of the former Prussian T 9.3 remained in Austria. However, only the two machines 91 1207 and 91 1347 were transferred to the ÖBB 691 series while retaining their Reichsbahn road numbers. The locomotives were modified in some technical details, the most noticeable being the equipment with a leading disc wheel set. Both representatives of the former T 9.3 used in the St. Pölten area were already taken out of service in 1957.
