3-pc. Passenger car set ÖBB Epoch IV

Set of three two-axle passenger cars type Bi chrome-blue. Different labels, half window versions

Based on the experiences before the war, the program for the production of railcar was developed at the end of the 1940s by ÖBB. With as few, uniquely designed parts as possible, one should try to replace the wooden boxes of the largest possible number of old buildings with steel structures. Basically, it was decided to build all two-axle and three-axle vehicles uniformly as two-axle trucks. 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 for a metropolitan area 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.
