Kriegsbauart

"R(r)(h) Stuttgart", "R(m)(r)s Stuttgart" with 8m axle base, after removal of stakes and waybill basket, finally used as a flatcar

The German term Kriegsbauart (wartime class) refers to railway goods wagon classes that were developed during the Second World War for the Deutsche Reichsbahn. The start of the war was an arbitrary dividing line for the classification of goods wagons, and did not represent any technological change. In the period shortly before the war, goods wagons were already being designed from a military perspective. This was particularly true for the stake wagons of 1938, which are occasionally referred to as a 'pre-war class' (Vorkriegsbauart) of wagons.

The transition from the welded Austauschbauart goods wagons to the first Kriegsbauart classes was therefore defined, not so much by design changes, but far more by a concentration on fewer types of wagons and their construction in greater numbers. The cause of this was the rapid increase in transportation tasks, because the railways in German were sucked into the events of war as never before. 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.

From 1954, the Deutsche Reichsbahn in East Germany put many goods wagons through its reconstruction programme. Some of these ''Reko'' goods wagons were in service until the start of the 1990s.

For consistency, the division of the goods wagons described in this article is based on that in the Austauschbauart article.

Standard Goods Wagons

Of the eight standard goods wagons that were built in significant quantities as Austauschbauart classes, there were only four types for which there was a further requirement in 1939: the two covered vans (G…s Oppeln and Gl…s Dresden), the stake wagons (Rs Stuttgart) and the open goods wagons (Om). 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. They sometimes had so-called refinements that speeded up production and minimised the amount of steel used.

For the open wagons, by contrast, not only was a higher maximum load demanded, but also a greater loading volume. As a result, in 1937/38 the Omm wagon was designed from scratch with a maximum load of 24.5 tons and a loading length of 8.72 metres (28.6 ft) (as opposed to 7.72 m or 25.3 ft on Om wagons). 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. A total of 73,850 of these wagons appeared in three variants:

outside 1941−43 18605
Ommru Villach 1.55 m (5 ft 1 in) high and fixed 1939−45 49115

All Omm wagons were equipped with Hildebrandt-Knorr brakes as well as, in some cases, hand brakes. The Ommr Linz wagons were especially well-suited to carrying vehicles and had special securing equipment for that purposes.

Standard Goods Wagons With Steel-Saving Features

During the war, the four standard goods wagons were sometimes redesigned with slightly different dimensions. They had to be sparing in their use of steel, and faster and cheaper to manufacture. Sometimes design solutions were found that clearly streamlined goods wagon construction. These wagons, built from 1943 onwards, were lighter than their predecessors, but at the same time could carry more. However, the cost of using cheaper steel and thinner profiles was greater wear and tear and a permanent deformation from the outset. As a result, after a few years, extensive improvements were needed.

Special Goods Wagons

More special wagons appeared, albeit no longer in pre-war quantities. Several classes, which had already been developed before 1939, continued in production, sometimes modified. In order of production quantity they were:
