Milwaukee Road Class ES-2
The Milwaukee Road's class ES-2 comprised four electric switcher locomotives. Two were built in 1916 and the final two in 1919. They were of steeplecab Steeplecab is railroad terminology for a style or design of electric locomotive; the term is rarely if ever used for other forms of power. The name originated in North America and has been used in Britain as well. A ''steeplecab'' design has ... design, with a single roof-mounted pantograph to access the Milwaukee's 3,000 V DC overhead line. Originally numbered 10050–10053, they were renumbered E80–E83 in March 1939. The ES-2 was the Milwaukee Road's primary class of dedicated electric switchers. Electric switching on the Milwaukee Road was always limited to the Rocky Mountain Division, and to the middle and east end only, Avery being merely a power change, rather than a switching, location. Harlowton's switching demands eventually exceeded the capabilities of the ES-2, which was replaced in 1951 by a single ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

Milwaukee Road Class EP-1, EF-1, EF-2, EF-3, And EF-5
The Chicago, Milwaukee, St. Paul and Pacific Railroad (Milwaukee Road) classes EP-1 and EF-1 comprised 42 boxcab electric locomotives built by the American Locomotive Company (Alco) in 1915. Electrical components were from General Electric. The locomotives were composed of two half-units semi-permanently coupled back-to-back, and numbered as one unit with 'A' and 'B' suffixes. As built, 30 locomotives were assigned to freight service, classified as EF-1 and numbered 10200–10229. The remaining twelve locomotives were assigned to passenger service as class EP-1, numbered 10100–10111, with higher-speed passenger gearing. The design was highly successful, replacing a much larger number of steam locomotives, cutting costs and improving schedules. General Electric self-proclaimed this electric locomotive to be the “King of the Rails” in a silent promotional film from 1915. In 1919, with the arrival of a newer generation of passenger power, the EP-1 locomotives were conv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Locomotives Introduced In 1916
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

Electric Locomotives Of The United States
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

General Electric Locomotives
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry. In some usages the term "general officer" refers to a rank above colonel."general, adj. and n.". OED Online. March 2021. Oxford University Press. https://www.oed.com/view/Entry/77489?rskey=dCKrg4&result=1 (accessed May 11, 2021) The term ''general'' is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of ''captain general'', which rank was taken from Middle French ''capitaine général''. The adjective ''general'' had been affixed to officer designations since the late medieval period to indicate relative superiority or an extended jurisdiction. Today, the title of ''general'' is known in some countries as a four-star rank. However, different countries use different systems of stars or other insignia for senior ranks. It has a NATO rank scal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3000 V DC Locomotives
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Milwaukee Road Class EF-4 And EP-4
The Little Joe is a type of railroad electric locomotive built by General Electric. The locomotives had twelve axles, eight of them powered, in a 2-D+D-2 arrangement. They were originally intended to be exported to the Soviet Union and designed to operate on Soviet Railways (SZhD) 3,300-volt DC overhead line system. They were never exported to the Soviet Union due to rising political tensions. Only 20 were built, with 15 sold to domestic operators and five exported to Brazil. History After World War II, the Soviet Railways continued its electrification program, this time targeting the Kropachyovo-Zlatoust-Chelyabinsk line of the South Urals Railway. As local factories were recovering from the war efforts, the Soviet government (then led by Joseph Stalin), ordered 20 of these locomotives. Known by their factory classification of GE 2-D+D-2 406/546 8-GE 750-3300V, in the Soviet Union, they would have received the classification of the A-series locomotive, with the A standing f ...

Current Collector
Electric current collectors are used by trolleybuses, trams, electric locomotives or EMUs to carry electrical power from overhead lines, electrical third rails, or ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies. Typically, electric current connectors have one or more spring-loaded arms that press a collector or contact shoe against the rail or overhead wire. As the vehicle moves, the contact shoe slides along the wire or rail to draw the electricity needed to run the vehicle's motor. The current collector arms are electrically conductive but mounted insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or motor. The steel rails of the tracks act as the electrical return. Electric vehicles that collect their current from an overhead line system use different forms of one- or two-arm pantograph ...

Black Start
A black start is the process of restoring an electric power station or a part of an electric grid to operation without relying on the external electric power transmission network to recover from a total or partial shutdown.Knight, U.G. ''Power Systems in Emergencies - From Contingency Planning to Crisis Management '' John Wiley & Sons 2001 section 7.5 The 'Black Start' Situation Power to restart a generating station may come from an on-site standby generator. Alternatively, where a large amount of power is required, a tie-line to another generating plant may be used to start the facility. Once the main generating units are running, the electrical transmission network can be re-connected and electrical loads restored. Black-start power may be ensured by an agreement where a particular energy supplier is paid to make black start power available when required. Not all generating plants are suitable for providing black-start power to a network. Station service power Electrical g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive Wheelslip
{{Unreferenced , date=September 2013 Locomotive wheelslip is an event that affects railway motive power usually when starting from stationary, but can also affect an engine in motion. Overview The greatest effort is required from a locomotive when starting. At this time, if the engineer applies too much power to the wheels (i.e., for a steam locomotive, the engineer opens the regulator too far) the turning force applied to the wheel will greatly exceed the opposing friction force affected by the surface of the rail, and the wheel will turn without being able to move the train forward. If the engineer does not take quick corrective action (i.e. by closing the regulator) the locomotive can end up stationary with its wheels spinning: this can damage both the locomotive drive mechanism, through running too fast, and the rail surface, which, in extreme cases, can be left with a dip where the spin took place. (Such a dip is dangerous if not repaired subsequently.) Some locomotive types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
