GE Dash 7 Series
The Dash 7 Series is a line of diesel-electric freight locomotives built by GE Transportation Systems. It replaced the Universal Series in the mid-1970s, and was superseded by the Dash 8 Series in the mid-1980s. Specifications All models of the Dash 7 Series are powered by a 12-cylinder or 16-cylinder, turbocharged, GE 7FDL 4-stroke diesel engine carried over from the Universal Series, and have speed-based adhesion control with a multi-channel LED annunciator panel. Dash 7 Series traction motors are powered by direct current. Construction history The Dash 7's predecessor, the Universal Series, had been introduced in the 1950s, and with its innovative body structure, it had initially been greeted favourably by the market. However, GM-EMD had then developed the GP30 model to compete with it; GP30 production had commenced in 1961. Over many years, the GP30's reliability had given it a sales advantage, and when EMD introduced its successor, the Dash 2, in 1972, the Univ ...

GE Universal Series Locomotives
The GE Universal Series are a series of diesel locomotives intended for the export market introduced by General Electric in early 1956. General Electric had previously partnered with Alco, producing locomotives for export using Alco’s 244 engine, and provided electrical parts for Alco’s domestic production. However, with the advent of the Universal Series, GE ended its partnership with Alco and entered the export locomotive market on its own. The export-oriented Universal Series should not be confused with the “U-Boats” for the North American market, which began with the U25B. The Universal Series are built to a much smaller loading gauge (Bern loading gauge) and are significantly lower in weight when compared to US locomotives sharing the same engine and horsepower rating. Universal Series locomotives can also be identified by the lack of battery boxes that are usually found under the cabins of North American locomotives. Naming convention The designations of the Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ticonderoga Class Cruiser
The ''Ticonderoga'' class of guided-missile cruisers is a class of warships in the United States Navy, first ordered and authorized in the 1978 fiscal year. The class uses passive phased-array radar and was originally planned as a class of destroyers. However, the increased combat capability offered by the Aegis Combat System and the AN/SPY-1 radar system, together with the capability of operating as a flagship, were used to justify the change of the classification from DDG (guided-missile destroyer) to CG (guided-missile cruiser) shortly before the keels were laid down for and . ''Ticonderoga''-class guided-missile cruisers are multi-role warships. Their Mk 41 VLS can launch Tomahawk cruise missiles to strike strategic or tactical targets, or fire long-range anti-aircraft SM-2MR/ ERs for defense against aircraft or anti-ship missiles. Their LAMPS III helicopters, RUM-139 ASROCs, and sonar systems allow them to perform anti-submarine missions. ''Ticonderoga''-class ships a ...

Seaboard Coast Line
The Seaboard Coast Line Railroad was a Class I railroad company operating in the Southeastern United States beginning in 1967. Its passenger operations were taken over by Amtrak in 1971. Eventually, the railroad was merged with its affiliate lines to create the Seaboard System in 1983. At the end of 1970, SCL operated 9,230 miles of railroad, not including A&WP-Clinchfield-CN&L-GM-Georgia-L&N-Carrollton; that year it reported 31,293 million ton-miles of revenue freight and 512 million passenger-miles. History The Seaboard Coast Line emerged on July 1, 1967, following the merger of the Seaboard Air Line Railroad with the Atlantic Coast Line Railroad. The combined system totaled , the eighth largest in the United States at the time. The railroad had $1.2 billion in assets and revenue with a 54% market share of rail service in the Southeast, facing competition primarily from the Southern. The seemingly redundant name resulted from the longstanding short-form names of these two m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Railway (US)
The Southern Railway (also known as Southern Railway Company and now known as the Norfolk Southern Railway) was a class 1 railroad based in the Southern United States between 1894 and 1982, when it merged with the Norfolk & Western to form Norfolk Southern. The railroad was the product of nearly 150 predecessor lines that were combined, reorganized and recombined beginning in the 1830s, formally becoming the Southern Railway in 1894. At the end of 1971, the Southern operated of railroad, not including its Class I subsidiaries Alabama Great Southern (528 miles or ); Central of Georgia (1729 miles); Savannah & Atlanta (167 miles); Cincinnati, New Orleans and Texas Pacific Railway (415 miles); Georgia Southern & Florida (454 miles); and twelve Class II subsidiaries. That year, the Southern itself reported 26,111 million net ton-miles of revenue freight and 110 million passenger-miles. Alabama Great Southern reported 3,854 million net ton-miles of revenue freight and 11 million pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD GP38-2
The EMD GP38-2 is an American four-axle diesel-electric locomotive built by General Motors, Electro-Motive Division. Part of the EMD Dash 2 line, the GP38-2 was an upgraded version of the earlier GP38. Power is provided by an EMD 645E 16-cylinder engine, which generates 2,000 horsepower (1.5 MW). GP38-2W The GP38-2W is a Canadian variant of the GP38-2. It is easily distinguished by its wide-nose Canadian comfort cab. 51 of these locomotives were produced for the Canadian National Railway during 1973–1974. Although a W is commonly suffixed to the name, it is actually an addition by enthusiasts to help specify the presence of a CN-spec comfort cab. No locomotives built using CN's design of comfort cab ever featured a W in their designation, as the presence of the cab did not mechanically alter the locomotive. This is reflected by the lack of the "W" in the model designation on the builders' plates of these units. There are snow shields above the inertial-filter central a ...

GE U23B
The GE U23B was a 2,250 horsepower diesel-electric locomotive built by GE Transportation from 1968 to 1977. It was one of the most successful models of the Universal Series, with 481 units built, including 16 exported to Peru. The U23B was replaced by the B23-7. History Featuring a 12 cylinder FDL engine, the U23B was a derivative of the U30B with a lower horsepower rating, producing 2,250 hp compared to the U30B's 3,000 hp. A variant with 6 axles instead of 4 was produced, known as the U23C. Original owners Surviving locomotives Not many U23Bs still exist, but a few shortline and regional railroads still use them in everyday service. The Georgia Central Railway was one of the last U23B holdouts, rostering almost all of the remaining ex Southern Railway (U.S.) high short hood U23Bs. The Georgia Central as of July 2015 has all of its U23Bs off of the roster with the 3965 going to the Southern Appalachia Railway Museum in Oak Ridge, TN. Another U23B, CSX 9553, former L&N ...

AAR Wheel Arrangement
The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads. Essentially a simplification of the European UIC classification, it is widely used in North America to describe Diesel locomotive, diesel and electric locomotives (including third-rail electric locomotives). It is not used for steam locomotives, which use the Whyte notation instead. The AAR system counts axles instead of wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to two powered axles in a row, "C" to three powered axles in a row, and "D" to four powered axles in a row. "1" refers to one idler axle, and "2" to two idler axles in a row. A dash ("–") separates Bogie, trucks or wheel assemblies. A plus sign ("+") refers to articulation, either by connecting bogies with span bolsters or by connecting individual locomotives via solid drawbars instead of ...

EMD Dash 2
The EMD Dash 2 is a line of diesel-electric locomotives introduced by General Motors' Electro-Motive Division (EMD) on January 1, 1972. Designations of these models were those of the former models with "-2" added (e.g., the SD40 was replaced by the SD40-2). They retained the basic specifications of the earlier models in terms of power output and most other features, but introduced a number of improvements to the locomotives' internal systems, specifically the electrical systems and the trucks of the locomotives. These were intended to improve availability, efficiency, and ease of maintenance. One major improvement was a modularized electrical control cabinet, allowing maintenance by unit replacement and the use of common parts. These concepts were first tested on the DDA40X. Changes Minor externally visible changes common across the whole line include the following: * Modified trucks with damping struts. Four-axle trucks have damping struts on two diagonally opposite corners. Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD GP30
The EMD GP30 is a four-axle diesel-electric locomotive built by General Motors Electro-Motive Division of La Grange, Illinois between July 1961 and November 1963. A total of 948 units were built for railroads in the United States and Canada (2 only), including 40 cabless B units for the Union Pacific Railroad. It was the first so-called "second generation" EMD diesel locomotive, and was produced in response to increased competition by a new entrant, General Electric's U25B, which was released roughly at the same time as the GP30. The GP30 is easily recognizable due to its high profile and stepped cab roof, unique among American locomotives. A number are still in service today in original or rebuilt form. History Development The GP30 was conceived out of the necessity of matching new competitor GE's U25B. The U25B offered while EMD's GP20 and its 567D2 prime mover was only rated at . The U25B also featured a sealed, airtight long hood with a single inertial air intake fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
