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 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 (as opposed to on Om wagons). Construction began in 1939. Notable external features are the axle base of and the three-dimensional strut frame that tapers downwards to a point. A total of 73,850 of these wagons appeared in three variants: 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kriegsbauart」の詳細全文を読む スポンサード リンク
