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′ (UIC) or Bo-Bo (Commonwealth) is the 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AAR Wheel Arrangement
The AAR wheel arrangement system is a method of classifying locomotive A locomotive is a rail transport, rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for ... (or unit) wheel arrangements that was developed by the Association of American Railroads. Essentially a simplification of the European UIC classification, it is widely used in North America to describe Diesel locomotive, diesel and electric locomotives (including third-rail electric locomotives). It is not used for steam locomotives, which use the Whyte notation instead (except geared steam locomotives, which are instead classified by their model and their number of trucks). The AAR system (like UIC) counts axles, unlike Whyte, which counts wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to t ...

Diesel-hydraulic Locomotive
A diesel locomotive is a type of railway locomotive in which the power source 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. The most common are diesel–electric locomotives and diesel–hydraulic. 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 leve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crowcombe 832 Light Engine To Bishops Lydeard
Crowcombe is a village and civil parish under the Quantock Hills in Somerset, England, southeast of Watchet, and from Taunton. The village has a population of 489. The parish covers the hamlets of Crowcombe Heathfield, Flaxpool, Halsway, Lawford and Triscombe. The village is on the route of the Samaritans Way South West. History The name Triscombe is believed to derive from the Old English words and . The first documentary evidence of the village is by Æthelwulf of Wessex in 854, where it was spelt 'Cerawicombe'. At that time the manor belonged to Glastonbury Abbey. Later Gytha Thorkelsdóttir, wife of Earl Godwin, gave it to the monks of Winchester to make amends for her husband's "treacherous abuses of divers monastic institutions". The Domesday Book of 1086 lists the village as 'Crawcombe', which is believed to come from the Old English words ''craw'' and ''cumb''. The parish of Crowcombe was part of the Williton and Freemanners Hundred. The medieval cross of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indian Locomotive Class WAG-12
The Indian locomotive class WAG-12B is a class of 25 kV AC railway electrification, 25 kV AC twin section electric locomotives that was developed in 2017 by Alstom with technological collaboration with Indian Railways. The model name stands for wide gauge (W), alternating current (A), goods traffic (G) locomotive-12. They entered trial service in 2019. As June 2025, a total of 520 WAG-12B were built at the 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, Indian locomotive class WAG-9, WAG-9. The locomotive was developed for use on Dedicated Freight Corridor Corporation of India, dedicated freight corridors, where it is used to haul freight trains weighing more than at speeds of to , 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 Corr ...

China Railways HXD2
The HXD2 () is an electric locomotive and a series of related locomotive classes built by CRRC Datong Electric Locomotive and Alstom. The locomotives designs are based on the Alstom Prima electric locomotives, and are a product of a cooperation agreement signed between the two companies in 2004. All locomotives are intended for heavy freight work, including coal trains on the Datong Qinhuangdao line ( Daqin Railway). The original HXD2 locomotives are twin unit Bo′Bo′+Bo′Bo′ vehicles whereas the HXD2B and HXD2C versions are single unit Co′Co′ machines. At the time of their construction the HXD2 and HXD2B locomotives were amongst the most powerful locomotives in the world. The HXD2C is similarly specified to the HXD2B but of reduced power, and with increased localisation of components for lower cost. The HXD2 was originally described as the DJ4-6000 class. Variants of the type were produced for railways other than China Railway: in 2010 Belarus state railways o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prima (locomotive)
Prima is a family of railway diesel and electric locomotives built by Alstom. Manufacture of the type commenced in the late 1990s. By 2008, Alstom had reportedly sold 1,750 Prima locomotives. The second generation Prima II was launched in 2009. The Prima H3 diesel/battery hybrid locomotive was launched in 2013. The Alstom Prima was superseded by Alstom Traxx in the summer of 2023. 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.

Flexicoil Suspension
Flexicoil suspension is a type of secondary suspension for railway vehicles, typically having steel coil springs between the bogies and chassis of a passenger coach, freight car, or locomotive. Suspension systems using steel springs are more common than those with air springs, as steel springs are less costly to make, relatively wear resistant, and require less maintenance. History Flexicoil (though not known by this term) suspensions were fitted to locomotives in Spain, the Soviet Union and Africa as early as the 1930s. In Germany, Flexicoil suspensions were first used in the 1950s under high-speed electric locomotives, notably the DB Class 103. British Rail Between 1969 and 1971, British Rail conducted tests of modified Flexicoil bogies under a modified Class 86, to prevent further track damage caused by the original Class 86 bogies; tests were successful and all Class 86 locomotives were refitted with the modifications in stages through the 1970s and 1980s.
