MP 59
The MP 59 (French : Métro sur Pneus d'appel d'offres de 1959) is a rubber tyred variant of electric multiple units used on the Paris Métro system, and is the oldest type still in regular passenger service. Manufactured by a consortium between CIMT-Lorraine (body), Jeumont-Schneider (control circuits), Alsthom and CEM (motors), they were first introduced in 1963 when the busiest routes of Lines 1 and 4 were converted to rubber tyred pneumatic operation. The trains circulated on Line 1 between 1963 and 2000, and Line 4 between 1967 and 2012. Today, 24 trains (originally from Line 1) operate on Line 11. Conception Following the success of the MP 55 rolling stock on Line 11, which saw a 5.5% increase in transport capacity, the RATP decided to study the expansion of rubber tyred rolling stock on other metro lines. The decision was made to first convert Line 1, due to it being the busiest line in the system. The decision to also equip Line 4 with rubber tyred stock soon follo ...

Paris Métro Line 11
Paris Métro Line 11 ( French: ''Ligne 11 du métro de Paris'') is one of the sixteen lines of the Paris Métro. It links Châtelet to Mairie des Lilas in the northeastern suburbs. At a length of 6.3 km (3.9 mi) and 13 stations served, it is currently the shortest of the 14 main Métro lines (excluding Line 3bis and Line 7bis) but is being extended by 6 stations. With 47.1 million riders in 2017, it is the thirteenth busiest line of the network. Unlike most Paris Métro lines, Line 11 was not included in the original late 19th century scheme. Designed to replace the former Belleville funicular tramway, it was opened in 1935 and intended to create a more effective transportation system which could handle the increasing traffic on the route, as well as to extend it to the center of Paris. An extension from Mairie des Lilas to Rosny-Bois-Perrier station is currently being built; featuring 6 stations, it will be opened in 2023. The rolling stock of the line is also being repla ...

Rheostatic Brake
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 electrical ...

Traction Motor
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric vehicle, electric or hydrogen vehicles, elevators or electric multiple unit. Traction motors are used in electrically powered rail vehicles (electric multiple units) and other electric vehicles including electric milk floats, elevators, roller coasters, conveyors, and trolleybuses, as well as vehicles with electrical transmission systems (Diesel locomotive#Transmission types, diesel-electric locomotives, electric hybrid vehicles), and battery electric vehicles. Motor types and control DC motor, Direct-current motors with series Field coil, field windings are the oldest type of traction motors. These provide a speed-torque characteristic useful for propulsion, providing high torque at lower speeds for acceleration of the vehicle, and declining torque as speed increases. By arranging the field winding with multiple taps, the speed characteristic can be varied, allowing relatively ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MP 55
The MP 55 was the first generation of the rubber tired variant of electric multiple units used on Paris's Métro system. The trains were manufactured by a consortium between Renault, Brissonneau et Lotz, and Alstom and operated on Line 11 from 1956 to 1999, when they were replaced by refurbished MP 59 stock from Line 4. Conception After the successful testing of the MP 51 test car on the ''la voie navette'' segment (connecting track) between Line 3bis and Line 7bis, the RATP decided to order 71 new train cars to equip Line 11, since the line contained a steep grade. The first train (M.3001-N.4001-AB.5501-M.3002) was delivered beginning on October 1, 1956 and went into service on November 8, 1956, with all 17 trains were in service by October 1957. Description The MP 55 was composed of 4 car trainsets, with three of the cars motorized. Originally, the trains were painted in a light blue livery and contained soft fluorescent lighting. Like many trains during the 1950s, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris Métro Line 4
Line 4 () is one of the sixteen lines of the Paris Métro rapid transit system. Situated mostly within the boundaries of the City of Paris, it connects Porte de Clignancourt in the north and Bagneux-Lucie Aubrac in the south, travelling across the heart of the city. Until it southern terminus was changed from Porte d'Orléans to Mairie de Montrouge in 2013, the line was sometimes referred to as the Clignancourt – Orléans Line. At in length, it connects with all Paris Métro lines apart from the very short 3bis and 7bis branch lines, as well as with all 5 RER express lines. It also serves three of the Paris Railway stations, Gare du Nord, Gare de l'Est, and Gare Montparnasse. It is the second-busiest Métro line after Line 1, carrying over 154 million passengers in 2004. Line 4 was the first line to connect to the south side of the River Seine, through an underwater tunnel built between 1905 and 1907. Line 4 long ran the oldest cars in service on the system, the MP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris Métro Line 1
Paris Métro Line 1 ( French: ''Ligne 1 du métro de Paris'') is one of the sixteen lines of the Paris Métro. It connects La Défense–Grande Arche in the northwest and Château de Vincennes in the southeast. Also, there is a future eastern extension planned to go to Val de Fontenay to make a link with Paris Metro Line 15, RER A, RER E and an extension of Tram 1. With a length of , it constitutes an important east–west transportation route within the City of Paris. Excluding RER (french: Réseau Express Régional) commuter lines, it is the most utilised line on the network with 181.2 million travellers in 2017 or 496,000 people per day on average. The line was the network's first to open, with its inaugural section entering service in 1900. It is also the network's first line to be converted from manually driven operation to fully automated operation. Conversion, which commenced in 2007 and was completed in 2011, included new rolling stock (MP 05) and laying of platform ed ...

Paris Métro
The Paris Métro (french: Métro de Paris ; short for Métropolitain ) is a rapid transit system in the Paris metropolitan area, France. A symbol of the Paris, city, it is known for its density within the capital's territorial limits, uniform architecture and Paris Métro entrances by Hector Guimard, unique entrances influenced by Art Nouveau. It is mostly underground and long. It has 308 stations, of which 64 have transfers between lines. The Montmartre funicular is considered to be part of the metro system, within which is represented by a 303rd fictive station "Funiculaire". There are 16 lines (with an additional four Grand Paris Express, under construction), numbered 1 to 14, with two lines, Paris Métro Line 3bis, 3bis and Paris Métro Line 7bis, 7bis, named because they started out as branches of Paris Métro Line 3, Line 3 and Paris Métro Line 7, Line 7 respectively.

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ...

Rubber-tyred Metro
A rubber-tyred metro or rubber-tired metro is a form of rapid transit system that uses a mix of road and rail technology. The vehicles have wheels with rubber tires that run on rolling pads inside guide bars for traction, as well as traditional railway steel wheels with deep flanges on steel tracks for guidance through conventional switches as well as guidance in case a tyre fails. Most rubber-tyred trains are purpose-built and designed for the system on which they operate. Guided buses are sometimes referred to as 'trams on tyres', and compared to rubber-tyred metros. History The first idea for rubber-tyred railway vehicles was the work of Scotsman Robert William Thomson, the original inventor of the pneumatic tyre. In his patent of 1846 he describes his 'Aerial Wheels' as being equally suitable for, "the ground or rail or track on which they run". The patent also included a drawing of such a railway, with the weight carried by pneumatic main wheels running on a flat board t ...

Wheel
A wheel is a circular component that is intended to rotate on an axle Bearing (mechanical), bearing. The wheel is one of the key components of the wheel and axle which is one of the Simple machine, six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples are found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of Axle, axles. In order for wheels to rotate, a Moment (physics), moment needs to be applied to the wheel about its axis, either by way of gravity or by the application of another external force or torque. Using the wheel, Sumer, Sumerians invented a device that spins clay as a potter shapes it into the desired object. Terminology The English word '':wi ...
