Shaped trolley
The frame wagons were passenger cars of the Austrian Federal Railways , which were created after the Second World War by converting older passenger cars with wooden car bodies . As with the German conversion cars , this conversion program resulted in an urgently needed renewal of the outdated and run-down rolling stock in the post-war period. The first frame wagons were developed in 1948 in the main workshop in Knittelfeld. The outwardly similar pre-war N 28 cars served as a model.
A frame is a closed angle iron shape, made of uniform rolled profiles, which corresponds to the box cross-section. Two frames were connected in a special device to form a window element, so that the window elements were identical to one another and thus also interchangeable. These window elements were placed on the old chassis , welded together and connected with angle iron. Then a 2 millimeter thin cladding sheet and a 1.5 mm thick roof sheet were welded on by means of plug welding. The inner lining was made using glued hardboard. It was also equipped with lightweight steel doors, 850 mm wide light metal windows and footboard lighting that was switched on when the entrance door was opened.
Most of the cars were converted in the main workshop in St. Pölten (standard and narrow gauge) or Simmering (standard gauge). This conversion program resulted in a large number of cars in the 1950s . The conversion program included both two-axle and four-axle cars on standard and narrow gauge . The two-axle standard-gauge wagons with open platforms were decommissioned in the early 1980s, only a few examples, which were painted blue and white, were declared as trailers for railcars , were used until 1988. Four-axle wagons were still widespread in the 1990s. The four-axle narrow-gauge wagons were last used in scheduled service on the Mariazell Railway . The narrow-gauge two-axle vehicles now form the backbone of the nostalgic train range on several narrow-gauge routes.
After the end of their service, numerous vehicles were used by museum and tourist railways, also outside of Austria .
Frame wagons look similar to the two-axle passenger cars built in 1921 to 1931 in Germany, the so-called Donnerbüchsen , some of which were also used in Austria.
