Alstom Prima Locomotives
Prima is a family of railway diesel and electric locomotives built by Alstom. During the late 1990s, manufacture of the type had commenced; by 2008, Alstom had reportedly sold 1,750 Prima locomotives. In 2009, the second generation Prima II was launched. During 2013, the Prima H3 diesel/battery hybrid locomotive was launched. First generation During 1998, the French national railway operator, SNCF, placed a large order with train manufacturer Alstom for 120 electric locomotives, which was later on increased to 240, to perform both domestic and international freight services. The company decided to develop a new modular platform that would accommodate the requirements not only of the existing SNCF order, but to also comply with European interoperability standards, as well as a high degree of flexibility as to meet the divergent needs of different operators, potentially increasing the type's international appeal. In this manner, the SNCF order can be attributed with the extension ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alstom Prima Diesel Locomotives
The Prima Diesel-electric locomotives are a class of medium and heavy, four- and six-axle, passenger and freight mainline locomotives. They have been built both to standard and broad gauges, and find use in the Middle East, Europe and North America. Alstom is the primary designer in cooperation with both General Motors (now EMD) and Siemens. History Initially the Prima locomotives were electric only, with the technology demonstrator and test platform being built in 2002 in Belfort France by Alstom. Next came the Prima 6000 technology demonstrator; this too was an electric locomotive, with 6000 kW of power and primarily intended to test and demonstrate multi-voltage operations for European cross-border operations. Orders for the Prima electrics came, mostly from SNCF. A series of diesel locomotives also associated with the Prima name were also built. These were the General Motors (GM)-engined machines built by Alstom at its Spanish plant in Valencia, and Ruston-engined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madhepura
Madhepura is a municipality in Madhepura district in the Indian state of Bihar. It stands at the centre of Kosi ravine, It was called ''Madhyapura-'' a place centrally situated which was subsequently transformed as Madhipura into present Madhepura.

Indian Locomotive Class WAG-12
The Indian locomotive class WAG-12B is a class of 25 kV AC electric locomotives that was developed in 2017 by Alstom with technological collaboration with Indian Railways. The model name stands for broad gauge (W), Alternating Current (AC), Goods traffic (G) locomotive, 12000 hp (12). They entered trial service in 2019. A total of 268 WAG-12B have been built at Electric Locomotive Factory, Madhepura, Bihar, India. With a power output of 12,000 HP, the WAG 12 is twice as powerful as its immediate predecessor, WAG-9, and is among the most powerful freight locomotives in the world. The locomotive is being developed for deployment on the Dedicated Freight Corridors, where it will be used to haul freight trains weighing more than at speeds of to , essentially doubling the average speed of freight trains in the sector. History Origins The origins of WAG-12B can be traced back to 2006. When the Government of India approved the Dedicated Freight Corridor (DFC) project ...

Broad Gauge
A broad-gauge railway is a railway with a track gauge (the distance between the rails) broader than the used by standard-gauge railways. Broad gauge of , commonly known as Russian gauge, is the dominant track gauge in former Soviet Union (CIS states, Baltic states, Georgia and Ukraine), Mongolia and Finland. Broad gauge of , commonly known as Irish Gauge, is the dominant track gauge in Ireland, and the Australian states of Victoria and Adelaide. Broad gauge of , commonly known as Iberian gauge, is the dominant track gauge in Spain and Portugal. Broad gauge of , commonly known as Indian gauge, is the dominant track gauge in India, Pakistan, Bangladesh, Sri Lanka, Argentina, Chile, and on BART (Bay Area Rapid Transit) in the San Francisco Bay Area. This is the widest gauge in common use anywhere in the world. It is possible for trains on both Iberian gauge and Indian gauge to travel on each other's tracks with no modifications in the vast majority of cases. History In Gr ...

Bogie Exchange
Bogie exchange is a system for operating railway wagons on two or more gauges to overcome difference in the track gauge. To perform a bogie exchange, a car is converted from one gauge to another by removing the bogies or trucks (the chassis containing the wheels and axles of the car), and installing a new bogie with differently spaced wheels. It is generally limited to wagons and carriages, though the bogies on diesel locomotives can be exchanged if enough time is available. Wagons and carriages Bogie wagons can have their gauge changed by lifting them off one set of bogies and putting them back down again on another set of bogies. The pin that centres the bogies and the hoses and fittings for the brakes must be compatible. A generous supply of bogies of each gauge is needed to accommodate the ebb and flow of traffic. The bogies and wagons also need to have standardized hooks, etc., where they may be efficiently lifted. The two wheel sets on four-wheel wagons can be change ...

25 KV AC
Railway electrification systems using alternating current (AC) at are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60Hz), which simplifies traction substations. The development of 25kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for railways that cover long distances or carry heavy traffic. After some experimentation before World War II in Hungary and in the Black Forest in Germany, it came into widespread use in the 1950s. One of the reasons why it was not introduced earlier was the lack of suitable small and lightweight control and rectification equipment before the development of solid-state rectifiers and related technology. Another reason was the increased clearance distances required where it ran under bridges and in tunnels, which would have required major civil engineering in order to provide the increased clearanc ...
