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] |
Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

Railcar
A railcar (not to be confused with a railway car) is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach (carriage, car), with a driver's cab at one or both ends. Some railway companies, such as the Great Western, termed such vehicles "railmotors" (or "rail motors"). Self-propelled passenger vehicles also capable of hauling a train are, in technical rail usage, more usually called "rail motor coaches" or "motor cars" (not to be confused with the motor cars, otherwise known as automobiles, that operate on roads). The term is sometimes also used as an alternative name for the small types of multiple unit which consist of more than one coach. That is the general usage nowadays in Ireland when referring to any diesel multiple unit (DMU), or in some cases electric multiple unit (EMU). In North America the term "railcar" has a much broader sense and can be used (as an abbr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Locomotive Class WDM-3A
The Indian locomotive class WDM-3A is a class of diesel–electric locomotive that was developed in 1993 by Banaras Locomotive Works (BLW), Varanasi for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, with 3300 horsepower (3A). The WDM-3A is a later classification of earlier WDM-2C. They entered service in 1994. A total of 143+ were built at ALCO and Banaras Locomotive Works between 1994 and 2003 with rest of the 1246 units being rebuilt from WDM-2 which made them the most numerous class of mainline diesel locomotive until the WDG-4. The WDM-3A is one of the most successful locomotives of Indian Railways serving both passenger and freight trains for over 26 years. A few WDM-3A units were exported to neighboring countries like Sri Lanka and Bangladesh. Despite the introduction of more modern types of locomotives like WDG-4 and electrification, a significant number are still in use, both in mainline and departmental duties. As ...

WDM-3
The Indian locomotive class WDM-3 is a class of Diesel–hydraulic locomotive that was developed in 1962 by Henschel for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, 3rd generation (3). They were inducted into service between 1970 and 1971. A total of eight WDM-3s were built between 1962 and 1970. They were decommissioned at Gooty in 1995. These diesel–hydraulic locomotives are not related to the ALCO WDM-3A. All are now retired from service. History Introduction A Mechanical Engineer of the Indian Railways developed a new hydro-mechanical transmission for diesel locomotives. The design was examined by the National Research and Development Corporation and was patented in India (as Suri transmission) sometime in 1956–57. In 1962, the Railway Board thought of developing Suri transmission in high horse-power locomotives in order to utilise its maximum benefit. For this purpose, the Railway board, in April 1962, auth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henschel & Son
Henschel & Son (german: Henschel und Sohn) was a German company, located in Kassel, best known during the 20th century as a maker of transportation equipment, including locomotives, trucks, buses and trolleybuses, and armoured fighting vehicles and weapons. Georg Christian Carl Henschel founded the factory in 1810 at Kassel. His son Carl Anton Henschel founded another factory in 1837. In 1848, the company began manufacturing locomotives. The factory became the largest locomotive manufacturer in Germany by the 20th century. Henschel built 10 articulated steam trucks, using Doble steam designs, for Deutsche Reichsbahn railways as delivery trucks. Several cars were built as well, one of which became Hermann Göring's staff car. In 1935 Henschel was able to upgrade its various steam locomotives to a high-speed Streamliner type with a maximum speeds of up to by the addition of a removable shell over the old steam locomotive. In 1918, Henschel began the production of gearboxes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indian Locomotive Class WDM-2G
The WDM-2G is a class of diesel electric genset locomotive used in Indian Railways. It is one of the rarest locomotives in India with only two units being produced by Patiala Locomotive Works (PLW). The locomotives were produced with an intention of being fuel efficient and to be used for light to medium duties such as short passenger runs along with occasional shunting. They are one of the only two classes of locomotives in India to feature multiple prime movers, the other example being WDS-6G, which was designed solely for shunting. They have a rated power of 2,400 HP. Development Diesel locomotives had been the backbone of the Indian Railways. Within the diesel fleet, the ALCOs, WDM-2, later upgraded to WDM-3A and other variants, were, and to some extent even continue to be, the major workhorses. This was before the, relatively recent, push of the Railways for complete electrification of the network. Being the major user of diesel locomotives, naturally, a large chunk ...
