The Deutsche Bundesbahn did not procure four-axle, covered freight wagons. In contrast, these were an important part of the DR's freight car fleet. Based on developments during the war, various types of four-axle, covered freight wagons were created, which were procured in large numbers. At the end of the development was the GGhrsz type, which was procured from 1966 onwards. Later, these cars were designated as Gagmrs-v, then as Gags (genus code number 1992). With this design, the final form of the four-axle, covered wagons of the Deutsche Reichsbahn was found. They were therefore procured in large numbers. The vehicles had a length of 16.52 m and a load capacity of 57 t. The superstructure was welded together from sheet metal, the floor was made of wood. After the fall of the Berlin Wall, these wagons were not included in the common freight wagon fleet, but some were still used as private wagons.
