EMD SD40-2W
The EMD SD40-2 is a C-C diesel-electric locomotive built by EMD from 1972 to 1989. The SD40-2 was introduced in January 1972 as part of EMD's '' Dash 2'' series, competing against the GE U30C and the ALCO Century 630. Although higher-horsepower locomotives were available, including EMD's own SD45-2, the reliability and versatility of the SD40-2 made it one of the best-selling models in EMD's history, edged only by the GP9, and the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the SD40, with modular electronic control systems similar to those of the experimental DDA40X. Peak production of the SD40-2 was in the mid-1970s. Sales of the SD40-2 began to diminish after 1981 due to the oil crisis, increased competition from GE's Dash-7 series and the introduction of the EMD SD50, which was available concurrently to late SD40-2 production. The last SD40-2 delivered to a United States railroad was built in July 1984, with pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD40
The EMD SD40 is an American 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between January 1966 and August 1972. 1,268 locomotives were built between 1966 and 1972. In 1972, an improved version with new electronics was developed and marketed as a new locomotive, the SD40-2. Design Like its predecessor in EMD's catalog, the SD35, the SD40 is a high-horsepower, six-axle freight locomotive. The SD40 is a member of EMD's long-running Special Duty class of locomotives, which all are built with 6 axles. In 1966, EMD updated its locomotive catalog with entirely new models, all powered by the new 645 diesel engine. These included six-axle models SD38, SD40, SDP40 and SD45. All shared standardized components, including the frame, cab, generator, trucks, traction motors, and air brakes. The primary difference was the power output: SD38 = from a non-turbocharged V16, SD40 = from a turbocharged V16, and SD45 = from a turbocharged V20. Original ...

EMD SD50
The EMD SD50 is a diesel-electric locomotive built by General Motors Electro-Motive Division. It was introduced in May 1981 as part of EMD's "50 Series"; production ceased in January 1986. The SD50 was a transitional model between EMD's Dash 2 series which was produced throughout the 1970s and the microprocessor-equipped SD60 and SD70 locomotives. A total of 431 were built. History The SD50 was produced in response to increasingly tough competition from GE Transportation, whose Dash 7 line was proving quite successful with railroads. While EMD's SD40-2 was a reliable and trusted product, GE's line included locomotives up to with more modern technology, as well as very competitive finance and maintenance deals. EMD responded throughout the SD50 program by offering discounts on large orders. The GM-EMD locomotives that immediately preceded the SD50, the SD45 and SD45-2, used huge, 20-cylinder engines that consumed large amounts of fuel and suffered from reliability probl ...

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 ...

DDA40X
The EMD DDA40X is a 6,600 hp (4,943 kW) D-D locomotive, built by EMD from 1969 to 1971 exclusively for the Union Pacific Railroad. It is the most powerful diesel-electric locomotive model ever built on a single frame, having two 16-645E3A diesel prime movers. Union Pacific has marked DD40X on the cab exteriors, while EMD literature inconsistently refers to this model as either DD-40X or DDA40X. UP's DDA40X locomotives were the ultimate culmination of the company's experiments with extremely powerful locomotives that began with its gas turbine-electric locomotives and DD35s. For manufacturer EMD, the construction of the world's most powerful single frame locomotive was a sign of the company's dominance of the North American diesel locomotive market, with only GE Transportation an equal competitor. The DDA40X also pioneered a number of new technologies that would go on to be incorporated in future EMD designs. Ultimately, UP did not continue with exceptionally powe ...

EMD GP9
The EMD GP9 is a four-axle diesel-electric locomotive built by General Motors' Electro-Motive Division between 1954 and 1959. The GP9 succeeded the GP7 as the second model of EMD's General Purpose (GP) line, incorporating a new sixteen-cylinder engine which generated . This locomotive type was offered both with and without control cabs; locomotives built without control cabs were called GP9B locomotives. EMD constructed 3,626 GP9s, including 165 GP9Bs. An additional 646 GP9s were built by General Motors Diesel, EMD's Canadian subsidiary, for a total of 4,257 GP9s produced when Canadian production ended in 1963. The GP9 was succeeded by the similar but slightly more powerful GP18. Design and Production EMD designed the GP9 as an improved version of the GP7, with an increase in power from 1,500 hp to 1,750 hp, and a change in prime mover to the latest version of the 567 engine, the 567C. Externally, the GP9 strongly resembled its predecessor. Most were built with high short ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD45-2
The EMD SD45-2 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). EMD built 136 locomotives between 1972–1974, primarily for the Atchison, Topeka and Santa Fe Railway (ATSF). The SD45-2 was an improved version of the EMD SD45; the primary visual difference is the lack of flared radiators on the SD45-2. Design Part of the EMD Dash 2 line, the SD45-2 was an upgraded SD45. Like the SD45, the SD45-2 had an EMD 645E3 20-cylinder engine producing . The main spotting difference between an SD45 and an SD45-2 was the long hood and the rear radiator. On the SD45 the long hood is flared whereas on the SD45-2 it is vertical and the rear cooling fans are more spread out on the top of the rear of the long hood. This unit used the same frame as the EMD SD40-2 and EMD SD38-2. The largest owner of the SD45-2 was the Atchison, Topeka, & Santa Fe with 90 units, the Clinchfield had 18 units, Seaboard Coast line had 15 units and Erie Lackawanna roster ...

ALCO Century 630
The ALCO Century 630 is a model of six-axle, diesel-electric locomotive built by the American Locomotive Company (ALCO) between 1965 and 1967. It used the ALCO 251 prime mover. 77 were built: 3 for Atlantic Coast Line Railroad, 4 for Chesapeake and Ohio Railway, 8 for Louisville and Nashville Railroad, 10 (with high noses) for Norfolk and Western Railway, 15 for Pennsylvania Railroad, 12 for the Reading Company, 15 for Southern Pacific Railroad and 10 for Union Pacific Railroad. Montreal Locomotive Works produced a C630M variant of the C630, with 4 for British Columbia Railway, 8 for Canadian Pacific Railway and 44 for Canadian National. MLW M630s were built by Montreal Locomotive Works from 1969 to 1973: 29 for CPR, 26 for BCR, and 20 for Ferrocarriles Nacional de Mexico (N de M). Eight of the BCR locomotives were designated M630(W) and were built with a wide-nosed cab, known as the "Canadian" or "safety" cab. The latter two models, along with the nearly identical MLW ...

GE U30C
The GE U30C is a six-axle locomotive built by General Electric from 1966 to 1976. With 600 units sold, the U30C proved to be a viable alternative for customers who were unable to purchase SD40s from Electro-Motive Diesel (EMD) due to production backlog. Throughout its ten-year production span, the U30C was known for reliability issues concerning its electrical system. However, most railroads were assured of the reliability of the GE Model 752 DC traction motor, and began to place orders for U30Cs starting in 1966. When production ended, the last U30Cs carried pre-Dash 7 specifications, which would be carried in its replacement, the GE C30-7. The U30C served customers of all kinds, from mining, to general freights, coal trains, and even as a power source unit for the Department of Transportation's subway-car test tracks in Pueblo, Colorado before a connection from the commercial electric power grid could be established . Not to be outdone in the freight sector, GE produced a passen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
