context_page_description: The German term Verbandsbauart describes both a type of goods wagon as well as a type of tram.
  In order to standardise the goods wagons classes of the various German state railways, the German State Railway Wagon Association issued regulations. The so-called Verbandsbauart or DWV wagons, named after this association, were built from 1910 until the emergence of the Austauschbauart wagons in 1927. Externally, the Verbandsbauart wagons looked very much like state railway goods wagons, but they were equipped for considerably higher maximum loads of up to 20 tons. A total of 11 classes were defined by norms defined by master engineering drawings. The wagons were built in numbers that today are hardly conceivable. The most important ones were the A2 and A10 Class wagons of which over 100,000 of each type were built. The Om Class A10 wagons were, including wagons of identical construction made by other nations, the most widespread goods wagons of all time and formed the major part of the German goods wagon fleet until the 1950s. Only then did they slowly disappear from the tracks. Many were also modified as part of the German goods wagon reconstruction programme.
context_section_description: The Class A6 open wagons were based on Prussian Sheet IIᵈ1. This truck was built from 1913, had steel sides and was built with and without hand brakes. The end wall was rotatable and enabled the truck to be unloaded at tipping facilities. They had a loading length of 5,300 mm, a loading width of 2,812 mm, a loading volume of  19.4 m³ and its carrying capacity was 15 tonnes.
  The wagons without hand brakes had a wheelbase of 3,000 mm, a length over buffers of 6,600 mm and their unladen weight was 7.3 tonnes. The open wagons with a brakeman's cab had a wheelbase of 3,300 mm, their length over buffers was 7,300 mm and their unladen weight was 8.6 tonnes.
  They were designated as "Omk[u]" by the state railways and give the classification "O Nürnberg" (Nürnberg = "Nuremberg") by the Deutsche Reichsbahn, whilst the Prussian coal truck built to Sheet IIᵈ1 was grouped as "O Schwerin" in the DR. Many of these wagons were used as slag or coal trucks exclusively to support the engine sheds or Bahnbetriebswerke.
