Based on the experiences before the war, the program for the production of frame cars was developed by ÖBB at the end of the 1940s. With as few as possible, uniquely designed parts should be tried to replace the wooden boxes of a large number of old buildings by steel structures. Basically, it was decided to build all two- and three-axle vehicles uniformly as a two-axle vehicle. The body frame was made of prefabricated frame "frames", which consisted of commercial rolled profiles made. In the design of the interior, it was decided to use a large space with the seat division 2 + 2. The conversion program was in addition to two- and three-axle Austrian designs and vehicles of German Länderbahnbauarten, which had remained at the end of the war on the territory of Austria included.
