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 GT46MAC ( SD70MAC derivative). The locomotive series is named Bheem, after the strong Pandav brother from epic Mahabharata. The loco has an 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, becoming GT-50, owing to the number of cylinders going from 16 to 20. Development of this locomotive is one of the Best Examples of Atma-Nirbhar Bharat. The clas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Diesel Locomotives Of India
This article lists the diesel locomotives that have operated or are operating on Indian Railways. Classification Locomotives were classified by track gauge, motive power, function and power (or model number) in a four- or five-letter code. The first letter denotes the track gauge. The second letter denotes motive power (diesel or electric), and the third letter denotes use (goods, passenger, mixed or shunting). The fourth letter denotes a locomotive's chronological model number. In 2002, a new classification system was adopted. For newer diesel locomotives, the fourth letter denotes their horsepower range. Not all diesel locomotives were reclassified, and the fourth letter continues to denotes their model number. A locomotive may have a fifth letter, generally denoting a technical variant, subclass or subtype: a variation in the basic model or series, or a different motor or manufacturer. Under the new system, the fifth letter further refines horsepower in 100-hp increments: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD80MAC
The 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 and SD45-2. 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, rear number boards, 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 Conrail, and the 28 produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of EMD Locomotives
The following is a list of locomotives produced by the Electro-Motive Corporation (EMC), and its successors General Motors Electro-Motive Division (GM-EMD) and Electro-Motive Diesel (EMD). Streamlined power cars and early experimental locomotives EMC participated in the construction of a number of motorized railcars, integrated streamliner trainsets, and experimental locomotives in the 1930s. Most of these were short production runs (one, two, or four units) that were used by a single railroad. These consisted of Winton prime movers and General Electric generating, control, and transmission components inside a carbody whose assembly was subcontracted to another manufacturer, since EMC did not commence regular road locomotive production until 1937. Switchers (SW/NW/SC/NC/MP) The "S" designation originally stood for six hundred horsepower and the "N" designation for nine hundred horsepower, although they were used for the more general designation of smaller and larger engine models ...

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 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 encountered during the developmen ...

Co-Co Locomotives
Co-Co is the wheel arrangement for diesel or electric locomotives with two six-wheeled bogies with all axles powered, with a separate traction motor per axle. The equivalent UIC classification (Europe) for this arrangement is Co′Co′, or C-C for AAR (North America). Use Co-Cos are most suited to freight work as the extra wheels give them good traction. They are also popular because the greater number of axles results in a lower axle load to the track. History The first mainline diesel-electric locomotives were of Bo-Bo arrangement. As they grew in power and weight, from 1937 the EMD E-units used an A1A-A1A layout with six axles to reduce axle load, but only four of them were powered. After WWII, the British LMS ordered two prototype locomotives with some of the first Co-Co arrangements. The first C-C design recorded was a narrow-gauge Hornsby opposed-piston Hornsby-Akroyd-engined locomotive of 1903 for the Chattenden and Upnor Railway. There was a two-speed mec ...

Rail Transport In India
Rail transport in India is an important mode of conveyance for people and goods in India. Indian Railways (IR) is the primary operator of rail operations throughout the country. IR is a state-owned organisation of the Ministry of Railways, which historically had its own government budget. Between 2019 and 2020, 22.15 million passengers used the Indian Railways network daily. In the same period, 3.32 million metric tons of freight was also shipped daily on the IR network. Other locally owned public corporations operate various suburban and urban railways throughout the country, such as Chennai Metro and the trams in Kolkata. Private sector operations currently exist only for freight trains and railroads, exclusively for non-passenger usage, but there were renewed efforts in 2020 to encourage private sector involvement in the running of passenger trains. In March 2020, the national rail network comprised of track over a route of and 7,325 stations. India's natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
