EMD SD70 Series
The EMD SD70 is a series of diesel-electric locomotives produced by the US company Electro-Motive Diesel. This locomotive family is an extension and improvement of the EMD SD60 series. Production commenced in late 1992 and since then over 5,700 units have been produced; most of these are the SD70M, SD70MAC, and SD70ACe models. While the majority of the production was ordered for use in North America, various models of the series have been used worldwide. All locomotives of this series are hood units with C-C trucks, except the SD70ACe-P4 and SD70MACH which have a B1-1B wheel configuration, and the SD70ACe-BB, which has a B+B-B+B wheel arrangement. Superseding the HT-C truck, a new bolsterless radial HTCR truck was fitted to all EMD SD70s built 1992–2002; in 2003 the non-radial HTSC truck (basically the HTCR made less costly by removing radial components) was made standard on the SD70ACe and SD70M-2 models; the radial HTCR truck remained available as an option.

Direct Current
Direct current (DC) is one-directional electric current, flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor (material), conductor such as a wire, but can also flow through semiconductors, electrical insulation, insulators, or even through a vacuum as in electron beam, electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A archaism, term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''Electric current, current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains Electronics, electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illinois Central Railroad
The Illinois Central Railroad , sometimes called the Main Line of Mid-America, is a railroad in the Central United States. Its primary routes connected Chicago, Illinois, with New Orleans, New Orleans, Louisiana, and Mobile, Alabama, and thus, the Great Lakes to the Gulf of Mexico. Another line connected Chicago west to Sioux City, Iowa (1870), while smaller branches reached Omaha, Nebraska (1899) from Fort Dodge, Iowa, and Sioux Falls, South Dakota (1877), from Cherokee, Iowa. The IC also ran service to Miami, Florida, on trackage owned by other railroads. The IC, founded in 1851, pioneered the financing later used by several long distance U.S. railroads whose construction was partially financed through a Land Grant Act of 1850, federal land grant. In 1998, the Canadian National Railway, via Grand Trunk Corporation, acquired control of the IC, and absorbed its operations the following year. The Illinois Central Railroad maintains its corporate existence as a non-operating subs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conrail
Conrail , formally the Consolidated Rail Corporation, was the primary Class I railroad in the Northeastern United States between 1976 and 1999. The trade name Conrail is a portmanteau based on the company's legal name. It continues to do business as an asset management and network services provider in three Shared Assets Areas that were excluded from the division of its operations during its acquisition by CSX Corporation and the Norfolk Southern Railway. The federal government created Conrail to take over the potentially profitable lines of multiple bankrupt carriers, including the Penn Central Transportation Company and Erie Lackawanna Railway. After railroad regulations were lifted by the 4R Act and the Staggers Act, Conrail began to turn a profit in the 1980s and was privatized in 1987. The two remaining Class I railroads in the East, CSX Transportation and the Norfolk Southern Railway (NS), agreed in 1997 to acquire the system and split it into two roughly-equal parts ...

Prime Mover (locomotive)
In engineering, a prime mover is an engine that converts chemical energy of a fuel into useful work. In a locomotive, the prime mover is thus the source of power for its propulsion. In an engine-generator set, the engine is the prime mover, as distinct from the generator. Definition In a diesel-mechanical locomotive, the prime mover is the diesel engine that is mechanically coupled to the driving wheels (drivers). In a diesel-hydraulic locomotive, the prime mover is the diesel engine that powers the pumps of one or more torque converters mechanically coupled to the drivers. In a diesel-electric locomotive, the prime mover is the diesel engine that rotates the main generator responsible for producing electricity to power the traction motors that are geared to the drivers. The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not p ...
