SD80MAC
The EMD SD80MAC was a C-C diesel-electric locomotive. It was powered by a 20-cylinder version of EMD's 710G prime mover, and was the second diesel locomotive by GM-EMD to use a V20 engine, since EMD's SD45 series. It introduced a wide radiator housing similar to GE Transportation locomotives and the placement of dynamic brakes at the rear of the locomotive, which is a quieter location, features that were incorporated into the SD90MAC and SD70ACe models. Key spotting differences between the SD80MAC and SD90MAC include no external rear sandbox on the SD90MAC, no rear lighted number boards on the SD90MAC, and the placement of the front numberboards (above the cab windows on the SD80MAC, on the nose on most SD90MACs). The SD80MAC also had recessed red marker lights in the nose, an identifying feature unique to Conrail (CR) locomotives, although Norfolk Southern (NS) had removed the lights on most of their former Conrail engines. All 30 SD80MAC units built were delivered to Conr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD90MAC
The EMD SD90MAC is a model of AAR wheel arrangement#C-C, C-C Diesel-electric transmission, diesel-electric locomotive produced by Electro-Motive Diesel, General Motors Electro-Motive Division (EMD). It is, with the EMD SD80MAC, SD80MAC, one of the largest single-engined locomotives produced by EMD and among the most powerful diesel-electric locomotives, surpassed only by the dual-engined EMD DDA40X, DDA40X. The SD9043MAC is the variant, using a 16-cylinder EMD 710, 710G engine instead of the EMD 265, H-engine, which was originally intended as a temporary alternative while EMD tried to solve the EMD 265, H-engine's issues. However, the accompanying upgrade program was never utilized by its customers. The SD90MAC's features include radial steering trucks with Alternating Current, AC traction motors and an isolated cab (locomotive), safety cab which is mounted on shock absorbers to lessen vibrations in the cab. The SD90MAC, like the SD80MAC, EMD SD70ACe, SD70ACe, and EMD SD70M- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD 710
The EMD 710 is a line of diesel engines built by Electro-Motive Diesel (previously General Motors' Electro-Motive Division). The 710 series replaced the earlier EMD 645 series when the 645F series proved to be unreliable in the early 1980s 50-series locomotives which featured a maximum engine speed of 950 rpm.40-series versions of the 645, save the initial teething problems with the 20-645E, which were eventually resolved, proved to be exceptionally reliable. The EMD 710 is a relatively large medium-speed two-stroke diesel engine that has displacement per cylinder, and a maximum engine speed of 900 rpm.Same parts suitable for 1000 rpm speed, yet rated lower because of earlier problems in EMD 645. Factory-fitted governor limits to 900 rpm. In 1951, E. W. Kettering (son of Charles F. Kettering) wrote a paper for the ASME entitled, ''History and Development of the 567 Series General Motors Locomotive Engine'', which goes into great detail about the technical obstacles that were e ...

Indian Locomotive Class WDG-5
The Indian locomotive class WDG-5 (EMD GT50AC) is a class of heavy haul Diesel–electric locomotive built by Banaras Locomotive Works, Varanasi in collaboration with Electro-Motive Diesel. At a rated power output of , it is the second most powerful diesel locomotive class on Indian Railways, just out-powered by the WDG-6G. Derived from the EMD SD80MAC, it was meant as a direct upgrade to the WDG-4 aka GT46MAC (an SD70MAC derivative). The locomotive series is named Bheem, after the strong Pandav brother from epic Mahabharata. The loco has the two-stroke Turbocharged EMD 20N-710G3B-EC ( 20 cylinder engine) of the EMD SD80MAC and an AC-AC transmission. Since the loco has been developed by installing a v20-710 prime mover and replacing the standard v16 in the WDG4 GT46MAC locomotive, the model was re-designated by adding 4 to the predecessor model, with GT-46 becoming GT-50, owing to the number of cylinders going from 16 to 20, thereby making it the First EMD locomotive in th ...

V20 Engine
A V20 engine is a twenty-cylinder piston engine where two banks of ten cylinders are arranged in a V configuration around a common crankshaft. Large diesel V20 engines have been used in diesel locomotives, haul trucks, electric generators and marine applications. History Beginning in the late-1930s, Mercedes-Benz produced several large V20 diesel engines for use in marine applications. The first engine was the ''MB 501'' which was based on the ''MB 500'' V12 engine and was installed in the 1937 class Schnellboot (fast attack boat) and several submarines. Later versions included the supercharged ''MB 511'' engine and the ''MB 518'', which also added an intercooler. A copy of the MB 511 was produced by VEB Motorenwerk in Ludwigsfelde and called the ''VEB 20 KVD 25''. Production of the MB 518 resumed in 1951, and a version of the engine was also manufactured by MTU, called the ''MB 20 V 672''. The Electro-Motive Diesel EMD 645E3 two-stroke V20 turbo-diesel engine was used in 1 ... [...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 ...

EMD SD40-2
The EMD SD40-2 is a AAR wheel arrangement#C-C, C-C diesel–electric locomotive built by Electro-Motive Diesel, EMD from 1972 to 1989. The SD40-2 was introduced in January 1972 as part of EMD's ''EMD Dash 2, Dash 2'' series, competing against the GE U30C. Although higher-horsepower locomotives were available, including EMD's own EMD SD45-2, SD45-2, the reliability and versatility of the SD40-2 made it one of the best-selling models in EMD's history, edged out only by the EMD GP9, GP9, and was the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the EMD SD40, 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 Dash 7 Series, GE's Dash-7 series and the introduction of the EMD SD50, which was available concurrently to late SD40-2 product ...
