EMD GP20D
The GP20D is a four-axle B-B switcher locomotive built by MotivePower and Electro-Motive Diesel. It was supplied with a Caterpillar 3516 ''(called a 16-170B20-T2 by EMD)'' V16 prime mover which develops a total power output of . To date, only 40 units have been produced by EMD, all of which were manufactured during June 2000. The GP20D is also a hood unit with lowered long and short hoods based on MotivePower's earlier MP2000D locomotives. The changes between the MK2000D and the GP20D are primarily in the control electronics, making them easier to use than the older model. Although the GP20D is marketed as a switcher, it has a top speed of , and is usually fitted with dynamic brakes, making it suitable for road switcher duties as well. The similar appearing EMD GP15D does not have dynamic brakes.

Switcher Locomotive
A switcher locomotive (American English), shunter locomotive (British English), or shifter locomotive (Pennsylvania Railroad terminology) is a locomotive used for maneuvering railway vehicles over short distances. Switchers do not usually move trains over long distances, instead they typically assemble trains in order for another locomotive to take over. Switchers often operate in a railyard or make short transfer runs. They may serve as the primary motive power on short branch lines or switching and terminal railroads. Switchers are optimized for their role, being relatively low-powered but with a high starting tractive effort for getting heavy cars rolling quickly. Switchers are geared to produce high torque but are restricted to low top speeds and have small diameter driving wheels. Switchers tend to be durable and to remain in service for a long time, such as the Swedish class U. American, Russian, Indian and Chinese switchers tend to be larger, with bogies to allow them t ...

EPA Tier 2-compliant Locomotives Of The United States
The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its administrator, who is appointed by the president and approved by the Senate. The current administrator is Michael S. Regan. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, triba ...

Railway Locomotives Introduced In 2000
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 ...

List Of GM-EMD Locomotives
The following is a list of locomotives produced by the Electro-Motive Corporation (EMC), and its successors General Motors Electro-Motive Division (GM-EMD) and Electro-Motive Diesel (EMD). Streamlined power cars and early experimental locomotives EMC participated in the construction of a number of motorized railcars, integrated streamliner trainsets, and experimental locomotives in the 1930s. Most of these were short production runs (one, two, or four units) that were used by a single railroad. These consisted of Winton prime movers and General Electric generating, control, and transmission components inside a carbody whose assembly was subcontracted to another manufacturer, since EMC did not commence regular road locomotive production until 1937. Switchers (SW/NW/SC/NC/MP) The "S" designation originally stood for six hundred horsepower and the "N" designation for nine hundred horsepower, although they were used for the more general designation of smaller and larger engine models ...

EMD GP15D
The GP15D is a four-axle B-B switcher built by MotivePower and Electro-Motive Diesel. It was supplied with a Caterpillar 3512 ''(called a 12-170B15-T2 by EMD)'' V12 prime mover which develops a total power output of . Ten units were manufactured by EMD during June 2000. Another 10 units were manufactured for Amtrak by MotivePower during 2004. The GP15D is a hood unit with lowered long and short hoods based on MotivePower' earlier MP1500D locomotives. The changes between the MP1500D and the GP15D are primarily in the control electronics, making them easier to use than the older model. Although the GP15D was marketed as a switcher, it has a top speed of 70 mph (113 km/h), making it suitable for road switcher duties as well. The GP15D is also similar in appearance to the contemporaneous GP20D, except that the 20 GP15D units produced to date do not have dynamic brakes.

Road Switcher
A road switcher is a type of railroad locomotive designed to both haul railcars in mainline service and shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere. A road switcher must be able to operate and have good visibility in both directions. As a road engine, a road switcher must be able to operate at road speeds, with suitable power and cooling capacity. It has high-speed road trucks rather than low-speed switcher only trucks. Modern road trucks are always equipped with "frictionless" roller bearings, whereas switcher trucks were almost always equipped with "friction" plain bearings, until plain bearings were outlawed in interchange service on both railcars and locomotives. Overview For the reasons given above, road switchers are generally hood units. The set-back cab of a hood unit provides more safety in the event of a collision at speed than most switcher designs, and the rear visibility is muc ...

Hood Unit
A hood unit, in North American railroad terminology, is a body style for diesel and electric locomotives where the body is less than full-width for most of its length and walkways are on the outside. In contrast, a cab unit has a full-width carbody for the length of the locomotive and walkways inside. A hood unit has sufficient visibility to be operated in both directions from a single cab. Also, the locomotive frame is the main load-bearing member, allowing the hood to be non-structural and easily opened or even removed for maintenance. History The hood unit evolved from the switcher locomotive. A switcher's long hood is normally low enough that the crew can see over it, and there typically is no short hood. Alco introduced the road switcher concept with the RS-1, which was an enlarged switcher with a short hood ahead of the cab. This was added to provide protection for the crew in case of a collision. The low long hood was retained, though its increased length made visibi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
