WDM-2
The Indian locomotive class WDM-2 is a class of diesel-electric locomotive that was developed in 1962 by American Locomotive Company (ALCO) for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, 2nd generation (2). They entered service in 1962. A total of more than 2,700 WDM-2 was built at ALCO and Banaras Locomotive Works (BLW or DLW, as it was formerly Diesel Locomotive Works), Varanasi between 1962 and 1998, which made them the most numerous class of mainline diesel locomotive until its successor the WDM-3A. The WDM-2 is one of the most successful locomotives of Indian Railways serving both passenger and freight trains for over 60 years. A few WDM-2 units were exported to neighbouring 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 of April 2022, 10 locomoti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ALCO DL560C
The ALCO DL560C is a series of diesel-electric locomotive with AC electric transmission designed by the American Locomotive Company and produced under license by Banaras Locomotive Works (BLW) Varanasi, India for Indian Railways as their classes WDM-2, WDM-3A/2C, WDM-3D and WDG-3A for operation in India. The locomotive is fitted with a 16-cylinder ALCO 251 B,C diesel engine. In the early 1960s Indian Railways needed a reliable diesel workhorse to gradually replace its steam locomotive fleet. Equal numbers (40 each) of ALCO's DL560C and EMD's G16 were chosen for trials. More locomotives of each of these were purchased for more trials. Indian Railways was keen on producing these locomotives in the country rather than depending on imports. EMD did not agree for a Transfer-of-Technology, while ALCO did. Thus ALCO DL560C was chosen for the job due to its easy maintenance, reliability and simple operation. And from then on vast numbers of this loco in different configurations have bee ...

Indian Locomotive Class WDM-1
The WDM-1 was the first class of Wide Gauge (W), Diesel powered (D), Mixed load (M), meant for hauling both freight and passenger trains. These are also the first mainline diesel engines imported after Independence. They were even the fastest diesel locomotives till the advent of WDM 2 and WDM 4. They used to haul ore/freight trains on SER. In the end, they were relegated to shunting/piloting duties or hauling sugarcane freight trains. One unit, #17000, is preserved at National Rail Museum, Delhi. WDM-1 * All locomotives of this class have been withdrawn from service.

Diesel-electric Train
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 qui ...

Road Switcher
A road switcher is a type of railroad locomotive designed to both haul railcars in mainline service and shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere. A road switcher must be able to operate and have good visibility in both directions. As a road engine, a road switcher must be able to operate at road speeds, with suitable power and cooling capacity. It has high-speed road trucks rather than low-speed switcher only trucks. Modern road trucks are always equipped with "frictionless" roller bearings, whereas switcher trucks were almost always equipped with "friction" plain bearings, until plain bearings were outlawed in interchange service on both railcars and locomotives. Overview For the reasons given above, road switchers are generally hood units. The set-back cab of a hood unit provides more safety in the event of a collision at speed than most switcher designs, and the rear visibility is ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevith ...
