Kriegsbauart

The start of the war was an arbitrary dividing line for the classification of goods wagons, and did not represent any technological change.

The Deutsche Reichsbahn was seen as an indispensable partner of National Socialism, both for the transportation of vehicles, troops and supplies as well as the deportation of Jews to the Nazi concentration camps.

Because the first three had been continuously developed during the 1930s, they still met wartime requirements and were built in very large batches during the early years of the war.

Construction began in 1939. Notable external features are the axle base of 6 m (20 ft) and the three-dimensional strut frame that tapers downwards to a point.

However, the cost of using cheaper steel and thinner profiles was greater wear and tear and a permanent deformation from the outset.

From 1921 all goods wagons with the same or similar functions were grouped into so-called class districts which were the names of German cities, mostly those in which there was a Reichsbahn divisional HQ.
