SNCF Class BB 900
The SNCF Class BB 900 was a class of 35 mixed-traffic electric locomotives built between 1936 and 1937 for État. The class was a development of the pre-war Midi Class E4700 and very similar to the later Class BB 300 and Class BB 325. Initial use was on the Paris–Le Mans line. The class was withdrawn in 1987 after 50 years in service. History Context In the early 1930s, the economic crisis hit and the government undertook major works to support employment, known as the Marquet plan. It was in this context that the decision was made to electrify the line from Paris-Montparnasse to Brest, between Paris and Le Mans. In anticipation of the completion of this work, the State company ordered two series of electric locomotives: the Class 2D2 5400 for the passenger services and the BB 900 for freight trains. The BB 900 were a development of the Midi E 4200 and E 4700 classes. The Midi company had a long experience in electric traction and the BB Midi were very successful. Co ...

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 B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheostatic Braking
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an el ...

Z 3800
Z (or z) is the 26th and last letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its usual names in English are ''zed'' () and ''zee'' (), with an occasional archaic variant ''izzard'' ()."Z", ''Oxford English Dictionary,'' 2nd edition (1989); ''Merriam-Webster's Third New International Dictionary of the English Language, Unabridged'' (1993); "zee", ''op. cit''. Name and pronunciation In most English-speaking countries, including Australia, Canada, India, Ireland, New Zealand and the United Kingdom, the letter's name is ''zed'' , reflecting its derivation from the Greek '' zeta'' (this dates to Latin, which borrowed Y and Z from Greek), but in American English its name is ''zee'' , analogous to the names for B, C, D, etc., and deriving from a late 17th-century English dialectal form. Another English dialectal form is ''izzard'' . This dates from the mid-18th century and probably derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montrouge
Montrouge () is a commune in the southern Parisian suburbs, located from the centre of Paris. It is one of the most densely populated municipalities in Europe. After a long period of decline, the population has increased again in recent years. History The name "Montrouge" means Red Mountain - from ''mont'' (mountain) and ''rouge'' (red) - because of the reddish colour of the earth in this area. The name of the community was first mentioned in monastery documents in 1194. Throughout the Middle Ages, the hamlet was home to monasteries and a number of religious orders, while in the 15th century it became the site of quarries used for the reconstruction of Paris. The late sixteenth century saw the plain of Montrouge named "reserve for royal hunts", and during the seventeenth and eighteenth centuries it was known for its windmills, which have all now disappeared. On 1 January 1860, the city of Paris was enlarged by annexing neighbouring communes. On that occasion, most of the comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemins De Fer Du Midi
The Compagnie des chemins de fer du Midi (. CF du Midi), also known in English as the Midi or Southern Railway, was an early French railway company which operated a network of routes in the southwest of the country, chiefly in the area between its main line – which ran from Bordeaux, close to the Atlantic coast, to Sète on the Mediterranean – and the Pyrenees. The company was established by the Pereire brothers, who thus broke the virtual monopoly held in France by James Rothschild on the slow-paced railway projects taking place in the area of Paris during the 1840s and 1850s. The Rothschild branch of Paris responded by strengthening its grip on the sector with an alliance to the industrialist Talabot. The Pereires in turn founded their financial company Crédit Mobilier. In 1934 the company was merged with the Chemin de fer de Paris à Orléans to become part of the Chemins de fer de Paris à Orléans et du Midi (PO-Midi). In 1856, the Midi completed its rail line fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
