DRG Class 61
The two German DRG Class 61 steam engines were express train locomotives specifically built by Henschel for the Henschel-Wegmann train in service with the Deutsche Reichsbahn. The Henschel-Wegmann train was an initiative of the German locomotive construction industry, intended to be able to demonstrate a powerful steam locomotive-hauled train alongside the emerging express diesel multiple units, such as the Hamburg Flyer. Construction Because it was planned to run the train in shuttle services to a tight time schedule, it was necessary that the engine could run at top speed in both directions. This resulted in a tank locomotive rather than the tender locomotive design otherwise used for long-distance high-speed links. In order to be able to attain the high running performance aimed at, locomotives and coaches were designed to be especially light, albeit the coal and water supplies still had to be sufficient for a one-way trip on the planned route. In building them, component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henschel & Sohn
Henschel & Son () was a German company, located in Kassel, best known during the 20th century as a maker of transportation equipment, including locomotives, trucks, buses and trolleybuses, and armoured fighting vehicles and weapons. Georg Christian Carl Henschel founded the factory in 1810 at Kassel. His son Carl Anton Henschel founded another factory in 1837. In 1848, the company began manufacturing locomotives. The factory became the largest locomotive manufacturer in Germany by the 20th century. Henschel built 10 articulated steam trucks, using Doble steam car, Doble steam designs, for Deutsche Reichsbahn-Gesellschaft, Deutsche Reichsbahn railways as delivery trucks. Several cars were built as well, one of which became Hermann Göring's staff car. In 1935 Henschel was able to upgrade its various steam locomotives to a high-speed Streamliner type with a maximum speeds of up to by the addition of a removable shell over the old steam locomotive. In 1918, Henschel began the pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DRG Class 03
The Class 03 Steam locomotive, steam engines were standard express train locomotives (''Einheitsdampflokomotive, Einheitslokomotiven'') in service with the Deutsche Reichsbahn-Gesellschaft, Deutsche Reichsbahn. History The Class 03 engines were built between 1930 and 1938 as express train locomotives for routes that were only suitable for axle loads of up to 18 tonnes. 298 examples of this engine, whose construction was based on the DRG Class 01, Class 01, were built by the firms of Borsig Lokomotiv Werke (AEG), Borsig, Krupp, Henschel, and Berliner Maschinenbau, Schwartzkopff. Its reduced weight was achieved by the use of a light sectional Locomotive frame, frame, smaller boiler and smaller Cylinder (steam locomotive), cylinders. From engine number 03 123 onwards the pumps were located in the centre of the locomotive and from number 03 163 the locos had larger leading wheels. Locomotive number 03 154 was equipped with a parabolic smokebox do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DRG Class 01
The Deutsche Reichsbahn-Gesellschaft's BR 01 steam locomotives were the first standardised (''Einheitsdampflokomotive'') steam express passenger locomotives built by the unified German railway system. They were of 4-6-2 "Pacific" wheel arrangement in the Whyte notation, or 2′C1′ h2 in the UIC classification. The idea of standardisation was that it would reduce maintenance costs; i.e. if a BR 01 whose engine shop was in, say, Berlin broke down in Dresden, instead of having to ship the necessary part from Berlin and take the locomotive out of service, a part from the Dresden shop could be used as all of the engines, parts, and workings were exactly the same and produced nationwide. Thus it was a "standard" product for engine shops. History The firms of AEG (German company), AEG and Borsig, who were the main manufacturers of these engines, together with Henschel, Lokomotivbau Hohenzollern, Hohenzollern, Krupp and Berliner Maschinenbau, BMAG previously Schwartzkopff, delivered ...

Streamliner
A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor " bullet trains". Less commonly, the term is applied to fully faired upright and recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels. Trains Before World War II Europe * Germany, 1930: The first high-speed streamliner in Germany was the '' Schienenzeppelin'', an experimental propeller-driven single car, built in 1930. On 21 June 1931, the car set a speed record of on a run between Berlin and Hamburg. In 1932 the propeller was removed and a h ...

Driving Wheels
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel locomotive, diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft (locomotive), Jackshaft drive and coupling rods were used in the past (e.g. in the Crocodile (locomotive), Swiss Crocodile locomotive) but their use is now confined to Switcher locomotive, shunter locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are groupe ... [...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 (horse tack), 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 500 class (steam)#Rebuilding, South Australian Railways they are called "valances". Overview Smoke deflectors became increasingly common on later steam locomotives because the velocity of the smoke exiting the chimney (locomotive), chimney had been reduced as a result of efficiency gains obtained by improved smokebox design, such as the Kylchap exhaust and Giesl ejector, and as boilers became larger the size of the chimneys had to be reduced to maintain loading gauge. Styles Various styles of smoke deflectors have been used by different railway operators. Howe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder (locomotive)
The cylinder is the power-producing element of the steam engine powering a steam locomotive. The cylinder (engine), cylinder is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were initially cast iron, but later made of steel. The cylinder casting includes other features such as (in the case of Stephenson's Rocket) valve ports and mounting feet. The last big American locomotives incorporated the cylinders as part of huge one-piece steel castings that were the Locomotive frame, main frame of the locomotive. Renewable wearing surfaces were needed inside the cylinders and provided by cast-iron bushings. The way the valve controlled the steam entering and leaving the cylinder was known as steam distribution and shown by the shape of the indicator diagram. What happened to the steam inside the cylinder was assessed separately from what happened in the boiler and how much friction the moving machinery had to cope wit ...

Overpressure
Overpressure (or blast overpressure) is the pressure caused by a shock wave over and above normal atmospheric pressure. The shock wave may be caused by sonic boom or by explosion An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be generated ..., and the resulting overpressure receives particular attention when measuring the effects of nuclear weapons or thermobaric bombs. Effects According to an article in the journal '' Toxicological Sciences'', Blast overpressure (BOP), also known as high energy impulse noise, is a damaging outcome of explosive detonations and firing of weapons. Exposure to BOP shock waves alone results in injury predominantly to the hollow organ systems such as auditory, respiratory, and gastrointestinal systems. An EOD suit worn by bomb disposal experts can protect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
