A total of 1,821 cars were rebuilt in the late 1950s, and part of this program was that the car frames were altered to a standard length of 19.45 meters or 63 feet 10-1/8 inches. The introduction of weather tight diaphragms between the cars was an important detail to enable passengers to board and get off of the train more quickly at station stops. In addition, all classes were equipped with upholstered seats for the first time. Like the three-axle rebuilt cars, the four-axle versions were built using old German State Railroad and provincial railroad cars.
