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 ...

WAG 9
The Indian locomotive class WAG-9 is a class of 25 kV AC electric locomotives that was developed in 1995 by ABB Group (ABB) for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods traffic (G), 9th generation (9) locomotive. They entered service in 1996. A total of 3651 WAG-9 have been built at Chittaranjan Locomotive Works (CLW), with more units being built at Banaras Locomotive Works (BLW), Bharat Heavy Electricals Limited (BHEL) and Patiala Locomotive Works (PLW). It was the most powerful freight locomotive of its fleet until the formal introduction of the WAG-12. The WAG-9 is one of the most successful locomotives of Indian Railways serving freight trains for over 26 years. A passenger variant of the WAG-9 was developed namely the WAP-7 locomotive by modifying the gear ratio to pull lighter loads at higher speeds. Nowadays, It is a common locomotive used in freight trains. Introduction The WAG-9 locomotive is referred to as the "Heavy Haul ...

Prima (locomotive)
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] |
Electric Locomotive Factory, Madhepura
The Electric Locomotive Factory, Madhepura is a joint venture of Alstom SA of France with Indian Railways for the production of 800 high-power locomotives over a period of 11 years designed to run on Indian tracks at . The manufacturing has started on 11 October 2017. The company's Madhepura facility is spread across and currently employs 70 people. It plans to ramp up production by 25% every year till it full capacity is reached. Alstom says its first locomotive will be ready for roll-out early 2019. On 10 April 2018, Prime Minister Narendra Modi dedicated India's first high-speed WAG-12 freight electric locomotive at Electric Locomotive Factory, Madhepura. The first five locomotives will be completed by 2019 followed by 35 locomotives by 2020, 60 in 2021, and by 100 every year till the target of 800 is reached. The company is also setting-up two maintenance depots at Saharanpur in Uttar Pradesh and Nagpur in Maharashtra. Location The factory is located at Madhepura, a c ...

Bo′Bo′+Bo′Bo′
B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives. Bo-Bo Bo-Bo is the UIC indication of a wheel arrangement for railway vehicles with four axles in two individual bogies, all driven by their own traction motors. It is a common wheel arrangement for modern electric and diesel-electric locomotives, as well as power cars in electric multiple units. Most early electric locomotives shared commonalities with the steam engines of their time. These features included side rods and frame mounted driving axles with leading and trailing axles. The long rigid wheelbase and the leading and trailing axles reduced cornering stability and increased weight. The Bo-Bo con ...

Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of re ...

Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...
