Monomotor Bogie
A monomotor bogie (french: bogie monomoteur) is a form of traction bogie (railway), bogie used for an electric locomotive or diesel-electric locomotive. It is distinguished by having a single traction motor on each bogie. Development The first electric locomotives used large diameter electric motors, mounted rigidly on their locomotive frame, frames and using jackshaft (locomotive), jackshaft drives and coupling rods to carry their torque to the driving wheels. This increased their unsprung weight and limited their maximum speed, despite the greater power of electric locomotives. Leading trucks To achieve a higher speed, locomotives began using wheel arrangements such as 2'Do2' (AAR: 2-Do-2), with the SNCF Class 2D2 5500 This used leading (and trailing) pony trucks or bogie (locomotive), bogies to provide stability at high speed, with individual traction motors for each axle, avoiding the weight of the coupling rods. Suspension travel for each axle was achieved with a Buchli dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogie (railway)
A bogie ( ) (in some Word sense, senses called a truck in North American English) is a chassis or framework that carries a Wheelset (rail transport), wheelset, attached to a vehicle—a Modularity, modular subassembly of Railroad wheel, wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly (trailer), dolly in a road train or in railway bogie exchange); it may contain a Suspension (vehicle), suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of continuous track, tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SNCF Class 2D2 9100
The Société nationale des chemins de fer français (; abbreviated as SNCF ; French for "National society of French railroads") is France's national state-owned railway company. Founded in 1938, it operates the 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. The SNCF Group employs more than 275,000 employees in France and around the world. Since July 2013, the SNCF Grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steeplecab
Steeplecab is railroad terminology for a style or design of electric locomotive; the term is rarely if ever used for other forms of power. The name originated in North America and has been used in Britain as well. A ''steeplecab'' design has a central driving cab area which may include a full-height area in between for electrical equipment. On both ends lower sloping hood contain other equipment, especially noisy equipment such as the air compressor not desired within the cab area. When overhead lines are used for power transmission, the cab roof usually supports the equipment to collect the power, either by pantographs, bow collectors or trolley poles. Although on some early designs such as the North Eastern Railways Electric number 1 a bow collector might be mounted on one of the hoods instead. History The ''steeplecab'' style was developed in America. The first ever built steeple cab was a 30-ton model built by General Electric (GE) in 1894. It was used in a textil ...

SNCF Class CC 14100
The SNCF Class CC 14100 was a class of 25 kV 50 Hz AC electric centre cab locomotives designed to haul heavy freight trains in the northeast of France and cross-border traffic into Luxembourg. A total of 101 locomotives were produced, numbered CC 14101 – CC 14202. Service use Introduced at the time when steam traction was being phased out, the torque of these locomotives was exceptional. During tests, a CC 14100 started a train weighing on an 1.1% slope, and a train on a 0.5% slope. Their slow speed of became a liability in later years and by 1986 individual locomotives were being withdrawn as they came due for overhaul or major repairs. The last members of the class survived until 1997, mainly on shunting duties. Preservation CC 14161 is on display on a short length of track next to a supermarket car park in Conflans-en-Jarnisy. CC 14183 is at the Carreau Wendel Museum at Petite-Rosselle Petite-Rosselle (; ; Palatine German: ''Klänrossle'') is a commune in the Mose ...

SNCF Class CC 14000
The Class CC 14000 were electric locomotives operated by SNCF in France. They were one of four classes, together with the BB 12000, BB 13000 and CC 14100 classes, that formed an experimental group for studying the practicality of the new French electrification. It was used in freight service along the Lille – Thionville line. They were nicknamed ''Fer à repasser'' (electric irons). History In this heavily industrialized area of the country with steep grades, the railway would pull heavy freight trains along the North-East line using SNCF 150.X steam locos, often requiring pusher locomotives to help move the trains along. The SNCF wanted to use only one locomotive on these trains and began studying the use of electric locomotives on the line. 25 kV 50 Hz electrification Around 1950, France began a program of electrification with 25 kV at the 'industrial' frequency of 50 Hz. An experimental program was begun with four similar locomotive designs, one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SNCF Class BB 13000
The BB 13000 class were electric locomotives operated by SNCF in France. They were one of four classes, together with the BB 12000, CC 14000 and CC 14100 classes, that formed an experimental group for studying the practicality of the new French electrification. 25 kV 50 Hz electrification The standard French electrification system before WWII was 1,500 V DC, beginning with locomotives such as the 2BB2 400. Post-WWII, France occupied the south-west of Germany and the Höllentalbahn. This line had been electrified with one of the first systems to use 50 Hz, the standard commercial distribution frequency, rather than the lower Hz AC frequency previously required for railway traction motors in Europe. The Höllentalbahn used a voltage of 20 kV. There was much interest post-war in using the 'industrial' frequency of 50 Hz and supplying the railways from the now established national systems of electricity generation, rather than requiring an isol ...

SNCF Class BB 12000
The SNCF Class BB 12000 were electric locomotives operated by SNCF, the French railway operator. The first examples arrived on the railway in 1953, operating on the 25 kV 50 Hz line to the coal mines of the ''Houillères de Lorraine'' in the north-east of France. History BB 12001 arrived in Mohon on July 17, 1954. Tried first along the Valenciennes – Lumes line, specifications called for a locomotive capable of pulling 750 tonne trains along a grade of 10 ‰. The 12000 Class proved more than capable, pulling 1100 tonne then 1400 tonne trains. BB 12006 using a different system of gears could pull 2000 tonne trains. The 12000s integrated well with the SNCF CC 14100 series. SNCF would own 148 of this type of locomotive and another 20 were delivered to the Société Nationale des Chemins de Fer Luxembourgeois in Luxembourg as their Class 3600, which had a longer life than their French counterparts: the last examples of this class were withdrawn in March 2005, by that point ...

Rotary Converter
A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting. They were commonly used to provide DC power for commercial, industrial and railway electrification from an AC power source. Principles of operation The rotary converter can be thought of as a motor-generator, where the two machines share a single rotating armature and set of field coils. The basic construction of the rotary converter consists of a DC generator (dynamo) with a set of slip rings tapped into its rotor windings at evenly spaced intervals. When a dynamo is spun the electric currents in its rotor windings alternate as it rotates in the magnetic field of the stationary field windings. This alternating current is rectified by means of a commutator, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Co'Co'
Co-Co is the wheel arrangement for diesel or electric locomotives with two six-wheeled bogies with all axles powered, with a separate traction motor per axle. The equivalent UIC classification (Europe) for this arrangement is Co′Co′, or C-C for AAR (North America). Use Co-Cos are most suited to freight work as the extra wheels give them good traction. They are also popular because the greater number of axles results in a lower axle load to the track. History The first mainline diesel-electric locomotives were of Bo-Bo arrangement. As they grew in power and weight, from 1937 the EMD E-units used an A1A-A1A layout with six axles to reduce axle load, but only four of them were powered. After WWII, the British LMS ordered two prototype locomotives with some of the first Co-Co arrangements. The first C-C design recorded was a narrow-gauge Hornsby opposed-piston Hornsby-Akroyd-engined locomotive of 1903 for the Chattenden and Upnor Railway. There was a two-speed me ...

Ignitron
An ignitron is a type of gas-filled tube used as a controlled rectifier and dating from the 1930s. Invented by Joseph Slepian while employed by Westinghouse, Westinghouse was the original manufacturer and owned trademark rights to the name "Ignitron". Ignitrons are closely related to mercury-arc valves but differ in the way the arc is ignited. They function similarly to thyratrons; a triggering pulse to the igniter electrode turns the device "on", allowing a high current to flow between the cathode and anode electrodes. After it is turned on, the current through the anode must be reduced to zero to restore the device to its nonconducting state. They are used to switch high currents in heavy industrial applications. Construction and operation An ignitron is usually a large steel container with a pool of mercury in the bottom that acts as a cathode during operation. A large graphite or refractory metal cylinder, held above the pool by an insulated electrical connection, serves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
