Welded Construction
Goods wagons of welded construction (german: Güterwagen der geschweißter Bauart) were developed and built by the Deutsche Reichsbahn in Germany from 1933 to about 1945. With the introduction of welding technology in 1933 almost all wagon components were joined by welding and no longer by rivetting. This enabled goods wagons to be designed, for example, for higher speeds or for higher payloads through the use of different types of steel and other engineering changes, but their further development was so heavily influenced by the exigencies of the Second World War that, as early as 1939, the Deutsche Reichsbahn had to temper the design of goods wagons to the new economic circumstances. Because there were overlaps in the change from the '' Austauschbauart'' - goods wagons made with interchangeable components - to the new welded classes, the period of the changeover cannot be exactly defined. Several standard goods wagons and their classes are covered in other articles. Goods wago ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsche Reichsbahn (1920–1945)
The ''Deutsche Reichsbahn'', also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the German national railway system created after the end of World War I from the regional railways of the individual states of the German Empire. The ''Deutsche Reichsbahn'' has been described as "the largest enterprise in the capitalist world in the years between 1920 and 1932"; nevertheless its importance "arises primarily from the fact that the Reichsbahn was at the center of events in a period of great turmoil in German history". Overview The company was founded on 1 April 1920 as the ("German Imperial Railways") when the Weimar Republic, which still used the nation-state term of the previous monarchy, (German Reich, hence the usage of the in the name of the railway; the monarchical term was ), took national control of the German railways, which had previously been run by the German states. In 1924 it was reorgan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class District
Class districts (german: Gattungsbezirke) were a classification system for railway goods wagons used by the Deutsche Reichsbahn (1920–1945) The ''Deutsche Reichsbahn'', also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the German national railway system created after the end of World War I from the regi ... in Germany between the wars. at web.hs-merseburg.de. Retrieved 19 Jun 2019 After the Deutsche Reichsbahn had been founded in 1920, in 1921 all goods wagons types with the same or similar roles were grouped into so-called class districts. These were named after cities that were the headquarters of a Reichsbahn division or, later, other cities too. Work on re-lettering and renaming the wagon ...

Verbandsbauart
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 (''Länderbahnen''), the German State Railway Wagon Association (''Deutscher Staatsbahnwagenverband'' or ''DWV'') issued regulations. The so-called ''Verbandsbauart'' (association) or ''DWV'' wagons, named after this association, were built from 1910 until the emergence of the Austauschbauart (interchangeable) 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 (''Musterblättern'').Literally "design sheets"; hence the specific wagon designs are referred to here as "Sheet X" The wagons were built in numbers that today are hardly conceivable. The most important ones were the A2 and A10 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German State Railway Norms
In German railway engineering, norms (''Normalien'') are standards for the design and production of railway vehicles. In the 1880s and 1890s, Prussian norms were developed for the locomotives, tenders and wagons of the Prussian state railways under the direction of the railway director responsible for railway engineering, Moritz Stambke. Later, these were largely adopted by the other state railways (''Länderbahnen'') in Germany. Engineering drawings These norms are defined by engineering drawings to 1:40 scale on individual sheets and show the locomotives and wagons as full design drawings, referred to by their sheet (''Musterblatt'') numbers. The first drawings date from 1878. In 1885 the Minister for Public Works tasked the Hütte Academic Institute with the publication of the norms. The drawings were regularly updated as technical developments occurred. The last Prussian drawings were issued in 1923. Goods wagons The design drawings for goods wagons were of special importanc ...

Brakeman's Cab
A brakeman's cabin (also brakeman's cab) or brakeman's caboose (US) (German: Bremserhaus) was a small one-man compartment at one end of a railway wagon to provide shelter for the brakeman from the weather and in which equipment for manually operating the wagon brake was located. They were built in the days before continuous braking was available and the locomotive brake needed to be augmented by brakemen applying the wagon brakes individually. History In the early years of the railway, brakemen just had an open seat. The first cabs appeared around 1880. The number of brakeman's cabs occupied in a given train depended on the conditions of the route and the speed of the train; on some trains all the cabs might be occupied. Communication between engine driver and brakemen was by train whistle signals which required the design of the brakeman's cab to be partially open to the elements. Risk Working in brakeman's cabins was dangerous, especially in winter because the cabins were un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

Kunze-Knorr Brake
The Kunze-Knorr brake (''Kunze-Knorr-Bremse'' or ''KK-Bremse'') is an automatic compressed-air brake for goods, passenger and express trains. It was the first graduated brake for goods trains in Europe. When it was introduced after the First World War, goods train brakes switched from hand operation to compressed-air in various European countries. The Deutsche Reichsbahn alone put the cost of equipping German goods wagons with Kunze-Knorr brakes between 1918 and 1927 at 478.4 million Reichsmarks. The operating cost savings from faster goods services and having fewer brakemen was assessed by the Reichsbahn at almost 96.3 million Reichsmark annually. Inventors The Kunze-Knorr brake brought together the ideas of Prussian senior surveyor, Bruno Kunze (1854–1935), and preparatory work by the founder of Knorr-Bremse, Georg Knorr (1859–1911). It was the first, continuous, compressed-air brake that, even on long goods trains, enabled the brake force not only to be applied gradually, ...

Broad Gauge
A broad-gauge railway is a railway with a track gauge (the distance between the rails) broader than the used by standard-gauge railways. Broad gauge of , commonly known as Russian gauge, is the dominant track gauge in former Soviet Union (CIS states, Baltic states, Georgia and Ukraine), Mongolia and Finland. Broad gauge of , commonly known as Irish Gauge, is the dominant track gauge in Ireland, and the Australian states of Victoria and Adelaide. Broad gauge of , commonly known as Iberian gauge, is the dominant track gauge in Spain and Portugal. Broad gauge of , commonly known as Indian gauge, is the dominant track gauge in India, Pakistan, Bangladesh, Sri Lanka, Argentina, Chile, and on BART (Bay Area Rapid Transit) in the San Francisco Bay Area. This is the widest gauge in common use anywhere in the world. It is possible for trains on both Iberian gauge and Indian gauge to travel on each other's tracks with no modifications in the vast majority of cases. History In Gr ...

Railway Air Brake
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, called the ''straight air system'', compressed air pushes on a piston in a cylinder. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train. Th ...
