NSB Di 6
NSB Di 6, later designated ME 26 and DE 2700, is a class of twelve diesel-electric locomotives built by Siemens for the Norwegian State Railways (NSB). The prime mover provides a power output of , a starting traction effort of and a maximum speed of . They have a Co′Co′ wheel arrangement. The bidirectional locomotives were designed for use with both passenger and freight trains. The units were ordered by NSB in 1992 as replacements for the aging Di 3, and were particularly intended for use on the Nordland Line and to a lesser extent on the Røros Line. Construction was done by Maschinenbau Kiel (MaK) in Kiel, Germany, which was then part of Siemens Schienenfahrzeugtechnik. The class is largely based on the MaK-built DB Class 240, with each unit costing 32 million Norwegian krone (NOK). The first units were delivered in March 1996, one year after schedule, but were plagued with faults. By 1999, the entire order was terminated and the locomotives returne ...

Røros Line
The Røros Line ( no, Rørosbanen) is a railway line which runs through the districts of Hedmarken, Østerdalen and Gauldalen in Innlandet and Trøndelag, Norway. The line branches off from the Dovre Line at Hamar Station and runs a more easterly route to Støren Station, where the two lines meet again. The Røros Line also intersects with the Solør Line at Elverum Station. The single track, standard gauge line lacks electrification and only has centralized traffic control south of Røros Station. The Norwegian State Railways (Vy) operate regional passenger trains. In addition the line is used by freight trains hauling lumber and wood chippings. The first parts of the line was the Hamar–Grundset Line and the Trondhjem–Støren Line, which opened on 23 June 1862 and 5 August 1964, respectively. To save costs, the lines were built with narrow gauge, thus making it the first locomotive-hauled line in Norway. The Grundset–Aamot Line extension to Rena Station was opened on 19 O ...

Thermal Shock
Thermal shock is a type of rapidly transient mechanical load. By definition, it is a mechanical load caused by a rapid change of temperature of a certain point. It can be also extended to the case of a thermal gradient, which makes different parts of an object expand by different amounts. This differential expansion can be more directly understood in terms of strain, than in terms of stress, as it is shown in the following. At some point, this stress can exceed the tensile strength of the material, causing a crack to form. If nothing stops this crack from propagating through the material, it will cause the object's structure to fail. Failure due to thermal shock can be prevented by: # Reducing the thermal gradient seen by the object, by changing its temperature more slowly or increasing the material's thermal conductivity # Reducing the material's coefficient of thermal expansion # Increasing its strength # Introducing built-in compressive stress, as for example in tempered ...

Track Force
As used in mechanical engineering, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion. In railway engineering, the term tractive effort is often used synonymously with tractive force to describe the pulling or pushing capability of a locomotive. In automotive engineering, the terms are distinctive: tractive effort is generally higher than tractive force by the amount of rolling resistance present, and both terms are higher than the amount of drawbar pull by the total resistance present (including air resistance and grade). The published tractive force value for any vehicle may be theoretical—that is, calculated from known or implied mechanical properties—or obtained via testing under controlled conditions. The discussion herein covers the term's usage in mechanical applications in which the final stage of the power transmission system is one or ...

Fuel Consumption
A fuel is any material that can be made to react with other substances so that it releases energy as thermal energy or to be used for work. The concept was originally applied solely to those materials capable of releasing chemical energy but has since also been applied to other sources of heat energy, such as nuclear energy (via nuclear fission and nuclear fusion). The heat energy released by reactions of fuels can be converted into mechanical energy via a heat engine. Other times, the heat itself is valued for warmth, cooking, or industrial processes, as well as the illumination that accompanies combustion. Fuels are also used in the Cell (biology), cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy. Hydrocarbons and related organic molecules are by far the most common source of fuel used by humans, but other substances, including radioactive metals, are also utilized. Fuels are contrasted with other s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternator
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History Alternating current generating ...

Fuel Tank
A fuel tank (also called a petrol tank or gas tank) is a safe container for flammable fluids. Though any storage tank for fuel may be so called, the term is typically applied to part of an engine system in which the fuel is stored and propelled (fuel pump) or released (pressurized gas) into an engine. Fuel tanks range in size and complexity from the small plastic tank of a butane lighter to the multi-chambered cryogenic Space Shuttle external tank. Uses Typically, a fuel tank must allow or provide the following: * Storage of fuel: the system must contain a given quantity of fuel and must avoid leakage and limit evaporative emissions. * Filling: the fuel tank must be filled in a secure way, without sparks. * Provide a method for determining level of fuel in tank, gauging (the remaining quantity of fuel in the tank must be measured or evaluated). * Venting (if over-pressure is not allowed, the fuel vapors must be managed through valves). * Feeding of the engine (throug ...

NSB Di 8
The NSB Di 8 is a class of diesel-electric locomotives built by Maschinenbau Kiel (MaK), while it was part of Siemens Schienenfahrzeugtechnik, for the Norwegian State Railways (NSB). The locomotives are equipped with a Caterpillar 3516 DI-TA prime mover, which provides a power output of and a starting tractive effort of . Twenty locomotives were delivered in 1996, largely based on MaK's previous production series, the Dutch NS Class 6400 and German DE 1002, although receiving some upgrades to the specifications. NSB took delivery of the class to replace the aging Di 3, and the units have been used on freight trains on un-electrified lines, including the Nordland Line and the Røros Line. They were transferred to CargoNet in 2002, when NSB's cargo division was demerged. Ten units were sold to GB Railfreight in 2011 and are used at the Scunthorpe Steel works in Scunthorpe, United Kingdom. History During the late 1980s, the Norwegian State Railways sought a new locomotive type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henschel
Henschel & Son (german: Henschel und Sohn) 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 designs, for 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 production of gearboxes at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NSB Di 4
NSB Di 4 is a class of five diesel-electric locomotives built by Henschel for the Norwegian State Railways (NSB). Delivered in 1981, the class is used to haul passenger trains on the Nordland Line and are since 2001 the only revenue diesel locomotives used by NSB. The locomotives had electric components from Brown, Boveri & Cie and a General Motors Electro-Motive Division 16-645E prime mover. This gives a power output of and a starting tractive effort of . The locomotives were ordered in the late 1970s as a supplement and later replacement of the Di 3. The class is technically similar to Denmark's DSB Class ME; it was planned to have commonalities with NSB's electric El 17 locomotives, but this was scrapped. The Di 4 was world's first asynchronous locomotive in revenue service. A second batch was planned delivered later in the 1980s, but the order was never placed. __TOC__ History During the 1950s and 1960s, NSB took delivery of thirty-five Di 3 locomotives.

Cargolink
Cargolink AS is a Norwegian railway company. Owned by the automotive distribution company Autolink, Cargolink has operated both autorack and container trains since November 2008. Cargolink has a fleet of ten diesel locomotives, five shunters, 100 autoracks and 60 container cars. Combined autorack and container trains are operated up to five times per week along the Sørland-, Bergen-, Rauma-, Røros- and Nordland Lines, as well as services through Sweden. Autolink, the largest distributor of automobiles in Norway, has traditionally bought train services from CargoNet. In 2007, they signed a contract with Ofotbanen, and at the same time bought 40% of the company. However, Ofotbanen was in financial difficulties, causing a dispute between the two owners. The result was that Autolink formally established Cargolink in March 2008, without the knowledge of Ofotbanen, and terminated the contract with Ofotbanen in July. Cargolink received an operating licence in September and service ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
