Diesel Multiple Unit
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a Transmission (mechanics), gearbox and driveshaft directly to the wheels of the train, like a automobile, car. The transmissions can be shifted manually by the driver, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JNR Kiha40 136 Erimo
The , abbreviated JNR or , was the business entity that operated Japan's national railway network from 1949 to 1987. Network Railways As of June 1, 1949, the date of establishment of JNR, it operated of narrow gauge () railways in all 46 prefectures of Japan. This figure expanded to in 1981 (excluding Shinkansen), but later reduced to as of March 31, 1987, the last day of JNR. JNR operated both passenger and freight services. Shinkansen Shinkansen, the world's first high-speed railway was debuted by JNR in 1964. By the end of JNR in 1987, four lines had been constructed: ; Tōkaidō Shinkansen: , completed in 1964 ; Sanyō Shinkansen: , completed in 1975 ; Tōhoku Shinkansen: , as of 1987 ; Jōetsu Shinkansen: , completed in 1982 Buses JNR operated bus lines as feeders, supplements or substitutions of railways. The JR Bus companies are the successors of the bus operation of JNR. Ships JNR operated ferries to connect railway networks separated by sea or to meet other ...

Wheel
A wheel is a rotating component (typically circular in shape) that is intended to turn 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 can be found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for a wheel to rotate, a Moment (physics), moment must be applied to the wheel about its axis, either by gravity or by the application of another external force or torque. Terminology The English word '':wikt:wheel, wheel'' comes from the Old English word , from Proto-Germanic language, Proto-Germanic , ...

Contact Shoe
A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and Electric multiple unit, EMUs to carry electric power (Electric current, current) from overhead lines, electric third rails, or ground-level power supply, ground-level power supplies to the electrical equipment of the vehicles. Those for overhead wires are roof-mounted devices, those for rails are mounted on the bogies. Typically, electric current connectors have one or more spring-loaded arms that press a collector or contact shoe against the rail or overhead wire. As the vehicle moves, the contact shoe slides along the wire or rail to draw the electricity needed to run the vehicle's motor. The current collector arms are electrical conductivity, electrically conductive but mounted Electrical insulation, insulated on the vehicle's roof, side or base. An insulated cable connects the collector with the switch, transformer or Electric motor, motor. The Rail profile, stee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph (transport)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or trolley buses to collect power through contact with an overhead line. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the Rail profile, rails. Other types of current collectors include the bow collector and the trolley pole. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "current collector, shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad. The familiar diamond-shaped roller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. However, electrically powered single-unit railcars are also generally classed as EMUs. The vast majority of EMUs are passenger trains but versions also exist for carrying mail. EMUs are popular on intercity, commuter, and suburban rail networks around the world due to their fast acceleration and pollution-free operation, and are used on most rapid-transit systems. 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 ...

Consist
A train (from Old French , from Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and Passenger train, transport people or Rail freight transport, freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars. Passengers and cargo are carried in railroad cars, also known as wagons or carriages. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Many countries use rail transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomotive ...

Stadler GTW
The Stadler GTW (, ) is an articulated railcar for local transport made by Stadler Rail of Switzerland. History The Biel–Täuffelen–Ins-Bahn near Bern, Switzerland was looking for a lighter train model to replace its aging fleet, so that a low-floor system does not require heavy installations on the roof. Based on that requirement Stadler came up with a concept of placing most of the equipment in a central unit between the seating cars. While the BTI-Bahn tracks are meter gauge, Stadler presented the first prototype in 1995 set on standard-gauge track, and the Mittelthurgau-Bahn tested three prototypes on its standard-gauge network during 1996. The rolling stock for Mittelthurgau was later expanded to ten GTW 2/6 units (built 1998–1999) that are now part of the THURBO fleet (the three prototypes were sold to Italy). The next lots were produced in meter gauge and were delivered to the BTI-Bahn and the CEV-Bahn ( Chemins de fer électriques Veveysans) in 1997although t ...

British Rail Class 207
The British Rail Class 207 ( 3D) diesel-electric multiple units were built by BR at Eastleigh in 1962. The fleet had a lifespan of 42 years. The Southern Region class 201 to 207 DEMUs are nicknamed 'Thumpers' due to the distinctive sound of their engines. Operational history When new the class were used on the Oxted Line, and were mostly concentrated on services between and Uckfield and Eridge to Tonbridge via . Other routes that the units operated included occasional workings on the Marshlink Line, the Three Bridges to Tunbridge Wells Central Line and the Cuckoo Line. Following the closure of the last two of these routes the unit gained workings on the Redhill to Tonbridge Line, and were known to deputise for 3R units on the North Downs Line to . Most units were withdrawn in 1987 following the electrification of the Oxted Line's branch. Four of the seven surviving units were used on the Reading to Basingstoke Line between 1988 and 1993; once this had finished three were ...
