EMD GP15-1
The EMD GP15-1 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between June 1976 and March 1982. Intended to provide an alternative to the rebuilding programs that many railroads were applying to their early road switchers, it is generally employed as a yard switcher or light road switcher. This locomotive is powered by a 12-cylinder EMD 645E engine, which generates . The GP15-1 uses a frame, has a wheelbase of and has a length over couplers of . A total of 310 units were built for American railroads. A number of GP15-1s remain in service today for yard work and light road duty. The radiator section is similar to those found on the EMD SD40T-2 and EMD SD45T-2 "tunnel motors," leading some observers to incorrectly identify the units as such or as GP15Ts, and giving them the nickname "baby tunnel motors". Original Owners Missouri Pacific Railroad The Missouri Pacific Railroad purchased more units than the other three buyers combined. For spot ...

EMD SD45T-2
The SD45T-2 is a model of diesel-electric locomotive built by EMD for the Southern Pacific Railroad. Like the later SD40T-2 it is colloquially nicknamed a tunnel motor. 247 total units (including the original EMD/SP joint venture working Prototype) were produced from February 1972 to June 1975, including 84 for SP's subsidiary Cotton Belt. From April 1986 to December 1989, 126 were rebuilt and re-designated as ''SD45T-2R'', including 24 for Cotton Belt. The SD45T-2 is a variant of the venerable SD45 that featured the "Dash 2" upgrade components such as improved electronics and high traction trucks, with the "T" denoting its cooling system modifications. The intake for radiator cooling air was moved to the walkway level and the cooling fans themselves were under the radiator cores, instead of above. Tunnel motors were built for mountainous areas in the western United States, where SP had previously encountered repeated overheating issues on their SD45s. The later SD40T-2 looks ...

Apalachicola Northern
The AN Railway is one of several shortline railroad companies owned by the Genesee & Wyoming parent company. It operates between Port Saint Joe, Florida and a connection with the Florida Gulf & Atlantic Railroad at Chattahoochee, Florida. The railroad no longer reaches its namesake city of Apalachicola, Florida, as the rails have been removed between Franklin and Apalachicola. The railroad operates approximately of track. History The original line was constructed by the Apalachicola Northern Railroad between 1905 and 1910. The Apalachicola Northern continued to operate it through various corporate reorganizations until 2002, when it leased the line to the Rail Management Corporation, which also acquired its locomotives, rolling stock, and railroad equipment. The new company began operating on September 1, 2002. Genesee & Wyoming acquired the Rail Management Corporation and its railroads in 2005. Equipment Unlike most shortlines, the AN Railway's locomotive fleet consisted enti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chessie System
Chessie System, Inc. was a holding company that owned the Chesapeake and Ohio Railway (C&O), the Baltimore and Ohio Railroad (B&O), the Western Maryland Railway (WM), and Baltimore and Ohio Chicago Terminal Railroad (B&OCT). Trains operated under the Chessie name from 1973 to 1987. Headquartered in Cleveland, Ohio, the Chessie System was the creation of Cyrus S. Eaton and his protégé Hays T. Watkins, then president and chief executive officer of the C&O. A chief source of revenue for the Chessie System was coal mined in West Virginia. Another was the transport of auto parts and finished motor vehicles. The name "Chessie System" had been a popular nickname for the C&O since the 1930s, cemented with an advertising campaign that featured a sleeping kitten named Chessie. The 1970s holding company developed the "Ches-C" emblem: a kitten outline imposed on a circle, creating a rough letter C. This emblem was emblazoned on the front of all Chessie System locomotives, and also ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder (engine)
In a reciprocating engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Braking (locomotive)
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an electrical ...

Norfolk Southern Railway
The Norfolk Southern Railway is a Class I freight railroad in the United States formed in 1982 with the merger of Norfolk and Western Railway and Southern Railway. With headquarters in Atlanta, the company operates 19,420 route miles (31,250 km) in 22 eastern states, the District of Columbia, and has rights in Canada over the Albany to Montréal route of the Canadian Pacific Railway. NS is responsible for maintaining , with the remainder being operated under trackage rights from other parties responsible for maintenance. Intermodal containers and trailers are the most common commodity type carried by NS, which have grown as coal business has declined throughout the 21st century; coal was formerly the largest source of traffic. The railway offers the largest intermodal rail network in eastern North America. NS was also the pioneer of Roadrailer service. Norfolk Southern and its chief competitor, CSX Transportation, have a duopoly on the transcontinental freight rail li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CSX Transportation
CSX Transportation , known colloquially as simply CSX, is a Class I freight railroad operating in the Eastern United States and the Canadian provinces of Ontario and Quebec. The railroad operates approximately 21,000 route miles () of track. The company operates as the leading subsidiary of CSX Corporation, a Fortune 500 company headquartered in Jacksonville, Florida. CSX Corporation (the parent of CSX Transportation) was formed in 1980 from the merger of Chessie System and Seaboard Coast Line Industries, two holding companies which controlled a number of railroads operating in the Eastern United States. Initially only a holding company itself, the subsidiaries that made up CSX Corporation were gradually merged, with this process completed in 1987. CSX Transportation formally came into existence in 1986, as the successor of Seaboard System Railroad. In 1999, CSX Transportation acquired approximately half of Conrail, in a joint purchase with competitor Norfolk Southern Rai ...

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 (a ...

Chicago And North Western Railway
The Chicago and North Western was a Class I railroad in the Midwestern United States. It was also known as the "North Western". The railroad operated more than of track at the turn of the 20th century, and over of track in seven states before retrenchment in the late 1970s. Until 1972, when the employees purchased the company, it was named the Chicago and North Western Railway (or Chicago and North Western Railway Company). The C&NW became one of the longest railroads in the United States as a result of mergers with other railroads, such as the Chicago Great Western Railway, Minneapolis and St. Louis Railway and others. By 1995, track sales and abandonment had reduced the total mileage to about 5,000. The majority of the abandoned and sold lines were lightly trafficked branches in Iowa, Illinois, Minnesota, South Dakota and Wisconsin. Large line sales, such as those that resulted in the Dakota, Minnesota and Eastern Railroad, further helped reduce the railroad to a mainline ...
