SNCF Class CC 1100
The SNCF Class CC 1100 was a class of 12 centre cab electric shunting locomotives, the first two of which were originally ordered for the PO-Midi. Originally numbered E 1001–E 1012, under the 1950 SNCF renumbering they became CC 1101–CC 1112. They were built by Batignolles-Châtillon and Oerlikon, the first two, E 1001 and E 1002, in 1937 and the remaining ten, E 1003–E 1012, between 1943 and 1948. Completely rebuilt between 1989 and 1995, the last was withdrawn from service in 2005. Description Design considerations At the time of ordering, decommissioned main-line locomotives of Class BB 1320 and Class BB 1420 were used for shunting purposes in marshalling yards. This was not entirely satisfactory for several reasons: their tractive effort was insufficient at low speed, the cooling of their rheostats was a problem and the BB type suffered from limited adhesion but had an axle load which may be too great for the yard tracks. In response to these problems, the Pari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Villeneuve-Saint-Georges
Villeneuve-Saint-Georges () is a commune in the southeastern suburbs of Paris, France. It is located from the centre of Paris. People from Villeneuve-Saint-Georges are called ''Villeneuvois'' in French. History Prehistory and Antiquity Villeneuve-Saint-Georges was settled during the Paleolithic and the Neolithic ages at the meeting of the Yerres and the Seine rivers, as well at Triage, with evidence from archeological remains found by Francis Martin in the 19th century, which includes flints and some stone tools. After the battle of Melun during the Roman Empire, the area was integrated into the Roman Empire. A small town was built around the area, with the name of ''Villa Nova'' (Latin for ''new house''). Middle Ages In the Middle Ages, Villeneuve-Saint-Georges was a possession of the abbey of Saint-Germain-des-Prés. The addition of "Saint-Georges" in the name of the commune was after the remains of Saint George was brought back in AD 858. The strategic position on the r ...

Regenerative Braking
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This method contrasts with conventional braking systems. In those systems, the excess kinetic energy is converted to unwanted and wasted heat due to friction in the brakes, or with rheostatic brakes, where the energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can significantly extend the life of the braking system as the mechanical parts will not wear out quickly. General principle The most common form of regenerative brake involves an electric motor functioning as an electric generator. In elect ...

Electric Locomotives Of France
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of ...

SNCF Locomotives
The Société nationale des chemins de fer français (; abbreviated as SNCF ; French for "National society of French railroads") is France's national State-owned enterprise, state-owned railway company. Founded in 1938, it operates the Rail transport in France, country's national rail traffic along with Monaco, including the TGV, on France's high-speed rail network. Its functions include operation of railway services for passengers and freight (through its subsidiaries SNCF Voyageurs and Rail Logistics Europe), as well as maintenance and signalling of rail infrastructure (SNCF Réseau). The railway network consists of about of route, of which are high-speed lines and electrified. About 14,000 trains are operated daily. In 2010 the SNCF was ranked 22nd in France and 214th globally on the Fortune Global 500 list. It is the main business of the SNCF Group, which in 2020 had €30 billion of sales in 120 countries.

Nîmes
Nîmes ( , ; oc, Nimes ; Latin: ''Nemausus'') is the prefecture of the Gard department in the Occitanie region of Southern France. Located between the Mediterranean Sea and Cévennes, the commune of Nîmes has an estimated population of 148,561 (2019). Dubbed the most Roman city outside Italy, Nîmes has a rich history dating back to the Roman Empire when the city had a population of 50,000–60,000 and was the regional capital. Several famous monuments are in Nîmes, such as the Arena of Nîmes and the Maison Carrée. Because of this, Nîmes is often referred to as the " French Rome". Origins Nimes is situated where the alluvial plain of the Vistrenque River abuts the hills of Mont Duplan to the northeast, Montaury to the southwest, and to the west Mt. Cavalier and the knoll of Canteduc. Its name appears in inscriptions in Gaulish as ''dede matrebo Namausikabo'' ("he has given to the mothers of Nîmes") and "''toutios Namausatis''" ("citizen of Nîmes"). Nemausus was the ...

Paul Arzens
Paul Arzens (28 August 1903 – 2 February 1990) was a French industrial designer of railway locomotives and motor cars. Arzens was born in Paris, at an address along the on the northern side of the city. As a young man he studied at the École des Beaux-Arts and soon gained recognition as a talented artist able at this stage, unusually, to live reasonably well on the sales proceeds from his paintings. This gave him enough time to pursue other interests in the realms of engineering and design. As his life progressed he accumulated a large collection of his own paintings and gained a reputation for an acute reluctance to sell any. Cars In 1935, Arzens turned his interests to automobile engineering. He designed and constructed a six-speed automatic transmission that he installed in an old Chrysler and which worked. Robert Peugeot tried the car and was impressed, although hopes that the system might be adopted for the Peugeot 402 came to nothing, possibly because Peugeot had r ...

Chopper (electronics)
In electronics, a chopper circuit is any of numerous types of electronic switching devices and circuits used in power control and signal applications. A chopper is a device that converts fixed DC input to a variable DC output voltage directly. Essentially, a chopper is an electronic switch that is used to interrupt one signal under the control of another. In power electronics applications, since the switching element is either fully on or fully off, its losses are low and the circuit can provide high efficiency. However, the current supplied to the load is discontinuous and may require smoothing or a high switching frequency to avoid undesirable effects. In signal processing circuits, use of a chopper stabilizes a system against drift of electronic components; the original signal can be recovered after amplification or other processing by a synchronous demodulator that essentially un-does the "chopping" process.

Béziers
Béziers (; oc, Besièrs) is a Subprefectures in France, subprefecture of the Hérault Departments of France, department in the Occitania (administrative region), Occitanie Regions of France, region of Southern France. Every August Béziers hosts the famous ''Feria de Béziers'', which is centred on bullfighting. A million visitors are attracted to the five-day event. The town is located on a small Cliff, bluff above the river Orb (river), Orb, about from the Mediterranean Sea, Mediterranean coast and southwest of Montpellier. At Béziers, the Canal du Midi passes over the river Orb by means of the ''Orb Aqueduct, Pont-canal de l'Orb'', an Navigable aqueduct, aqueduct claimed to be the first of its kind. History Béziers is one of the oldest cities in France.

Flat Wagon
Flat wagons (sometimes flat beds, flats or rail flats, US: flatcars), as classified by the International Union of Railways (UIC), are railway goods wagons that have a flat, usually full-length, deck (or 2 decks on car transporters) and little or no superstructure. By contrast, open wagons have high side and end walls and covered goods wagons have a fixed roof and sides. Flat wagons are often designed for the transportation of goods that are not weather-sensitive. Some flat wagons are able to be covered completely by tarpaulins or hoods and are therefore suitable for the transport of weather-sensitive goods. Unlike a "goods wagon with opening roof", the loading area of a flat is entirely open and accessible once the cover is removed. Flats form a large proportion of goods wagons; for example in 1998 they comprised 40% of the total goods fleet owned by the German carrier, DB, the overwhelming majority of which were flat wagons with bogies. Typical goods transported by these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
