Einheitsdampfloks
The Einheitsdampflokomotiven ("standard steam locomotives"), sometimes shortened to ''Einheitslokomotiven'' or ''Einheitsloks'', were the standardized steam locomotives built in Germany after 1925 under the direction of the Deutsche Reichsbahn-Gesellschaft. Their manufacture made extensive use of standard design features and components. 300px, Einheitslok of the DRG_Class_01.html" ;"title="Historic Railway, Frankfurt DRG Class 01">Historic Railway, Frankfurt DRG Class 01 in 2007 Development Following the merger of the state railways (''Länderbahnen'') in Germany into the Reich railway in 1920 and into the Deutsche Reichsbahn-Gesellschaft in 1924, the locomotive fleet of the new national railway administration still had 210 different types and classes of steam engine. This considerably hindered the flexible employment of locomotives within the railway network, and servicing and maintenance was very costly as a result of the large number of different spare parts that had to be s ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

DRG Class 02
The German DRG Class 02 (''Baureihe 02'' or ''BR 02'') engines were standard ('' Einheitslokomotiven'') express train locomotives with the Deutsche Reichsbahn-Gesellschaft. Number 02 001 was the first ''Einheitsdampflokomotive'' in the DRG to be completed. In procuring a standard express train steam locomotive, the Deutsche Reichsbahn carried out a comparison between a superheated two-cylinder type (the DRG Class 01) and a four-cylinder compound locomotive (the Class 02). Ten examples of each type were built from 1925, and the Class 02 vehicles were given operating numbers 02 001 – 02 010. The first eight engines were manufactured in 1925 by the firm of Henschel, two more were built in 1926 by Maffei. Because the Class 02 steam engines were badly designed, the compound engine could only produce a high level of power at speeds of over 70 km/h. In addition, below 100 PSi its steam consumption was higher than that of the Class 01. Compared with the Class 01s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blast Pipe
The blastpipe is part of the exhaust system of a steam locomotive that discharges exhaust steam from the cylinders into the smokebox beneath the chimney in order to increase the draught through the fire. History The primacy of discovery of the effect of directing the exhaust steam up the chimney as a means of providing draft through the fire is the matter of some controversy, Ahrons (1927) devoting significant attention to this matter. The exhaust from the cylinders on the first steam locomotive – built by Richard Trevithick – was directed up the chimney, and he noted its effect on increasing the draft through the fire at the time. At Wylam, Timothy Hackworth also employed a blastpipe on his earliest locomotives, but it is not clear whether this was an independent discovery or a copy of Trevithick's design. Shortly after Hackworth, George Stephenson also employed the same method, and again it is not clear whether that was an independent discovery or a copy of one of the oth ...

Superheater
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet (a few metres to some hundred metres). Types * A radiant superheater is placed directly in radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. * A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. * A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system. This superheater design incorporates additional burners in the area of superheater pipes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smoke Deflectors
Smoke deflectors, sometimes called "blinkers" in the UK because of their strong resemblance to the blinkers used on horses, and "elephant ears" in US railway slang, are vertical plates attached to each side of the smokebox at the front of a steam locomotive. They are designed to lift smoke away from the locomotive at speed so that the driver has better visibility. On the South Australian Railways they are called "valances". Overview Smoke deflectors became increasingly common on later steam locomotives because the velocity of smoke exiting the chimney had been reduced as the result of efficiency gains obtained by improved smokebox design, such as the Kylchap exhaust and Giesl ejector. Styles Various styles of smoke deflectors have been used by different railway operators. However, many are essentially a variation of one of two designs of ''Windleitbleche'' (wind deflecting plates) developed by the Deutsche Reichsbahn-Gesellschaft The ''Deutsche Reichsbahn'', also known as ...

Tender Locomotive
A tender or coal-car (US only) is a special rail vehicle hauled by a steam locomotive containing its fuel (wood, coal, oil or torrefied biomass) and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are necessary to keep them running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board the locomotive itself are called tank locomotives. A corridor tender is a locomotive tender with a passageway to one side, allowing crew changes on the fly. A brake tender is a tender that is heavy and used (primarily) to provide greater braking efficiency. General functions The largest steam locomotives are semi-permanently coupled by a drawbar to a tender that carries the water and fuel. The fuel source used depends on what is economically available locally. In the UK and parts of Europe, a plentiful supply of coal made ...

Bogies
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.

Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...

Locomotive Frames
A locomotive frame is the structure that forms the backbone of the railway locomotive, giving it strength and supporting the superstructure elements such as a cab, boiler or bodywork. The vast majority of locomotives have had a frame structure of some kind. The frame may in turn be supported by axles directly attached to it, or it may be mounted on bogies ( UK) / trucks ( US), or a combination of the two. The bogies in turn will have frames of their own. Types of frame 250px, Preserved GWR 9017 showing outside frames Three main types of frame on steam locomotives may be distinguished:, p 255. Plate frames These used steel plates about thick. They were mainly used in Britain and continental Europe. On most locomotives, the frames would be situated within the driving wheels ("inside frames"), but some classes of an early steam locomotive and diesel shunters were constructed with "outside frames". Some early designs were double framed where the frame consisted of plates both in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kriegslok
''Kriegslokomotiven'' (german: for "war locomotives", singular: ''Kriegslokomotive'') or ''Kriegsloks'' were locomotives produced in large numbers during the Second World War under Nazi Germany. Their construction was tailored to the economic circumstances of wartime Germany along with conquered and occupied territories across Europe, taking account of the shortage of materials, the transportation of goods in support of military logistics, ease of maintenance under difficult conditions, resistance to extreme weather, limited life and the need for rapid, cheap mass production. In order to meet these requirements, economic drawbacks such as relatively high fuel consumption had to be accepted. Forced labour was used in the construction of some of the locomotives; German locomotive building firms employed prisoners from concentration camps and foreign, mostly Polish, workers. Construction The war locomotives (or ''Kriegslokomotiven'') were kept technically as simple as possible and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goods Train
Rail freight transport is the use of railroads and trains to transport cargo as opposed to human passengers. A freight train, cargo train, or goods train is a group of freight cars (US) or goods wagons (International Union of Railways) hauled by one or more locomotives on a railway, transporting cargo all or some of the way between the shipper and the intended destination as part of the logistics chain. Trains may haul bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars. Rail freight practices and economics vary by country and region. When considered in terms of ton-miles or tonne-kilometers hauled per unit of energy consumed, rail transport can be more efficient than other means of transportation. Maximum economies are typically realized with bulk commodities (e.g., coal), especially when hauled over long distances. However, shipment by rail is not as flexible as by the highway, which has resulted in much freight being haul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DRG Class 50
The DRB Class 50Wartime locomotives classes are prefixed DRB (Deutsche Reichsbahn) to distinguish them from those introduced by the DRG (prefixed DRG), which became defunct in 1937, and those introduced later by the East German Deutsche Reichsbahn (prefixed DR). is a German class of 2-10-0 locomotive, built from 1939 as a standard locomotive (''Einheitsdampflokomotive'') for hauling goods trains. It had one leading axle and five coupled axles and was one of the most successful designs produced for the Deutsche Reichsbahn. This class was procured as part of the German Nazi party's preparations for war that led into the Second World War. Up to 1948, 3,164 Class 50 engines were built by almost all the European locomotive factories – towards the end as so-called provisional war locomotives (''Übergangskriegslokomotiven'') and classified as 50 ÜK. At the end of the steam locomotive era, they became virtually a universal class of mixed-traffic steam engine that, thanks to their low ...
