The fleet operated on the Island Line was also replaced by the during 2021. Dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disc Brake
A disc brake is a type of brake that uses the #Calipers, calipers to squeeze pairs of #Brake pads, pads against a disc (sometimes called a [brake] rotor) to create friction. There are two basic types of brake pad friction mechanisms: abrasive friction and adherent friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into heat, which must be dissipated to the environment. Hydraulic brakes, Hydraulically Actuator, actuated disc brakes are the most commonly used mechanical device for slowing motor vehicles. The principles of a disc brake apply to almost any rotating shaft. The components include the disc, master cylinder, and caliper, which contain at least one cylinder and two Brake pad, brake pads on both sides of the rotating disc. Design The development of disc-type brakes began in England in the 1890s. In 1902, the Lanchester Motor Company designed bra ...

British Rail Class 380
The British Rail Class 380 ''Desiro'' is a type of electric multiple unit passenger train that operates on the National Rail network in Scotland, for ScotRail. The Class 380 operates various routes out of Glasgow Central station, Glasgow Central. History The trains operate ScotRail services in the Ayrshire and Inverclyde regions of Scotland and had originally been intended for the cancelled Glasgow Airport Rail Link.

All 38 units are owned by Eversholt Rail, a rolling stock company (ROSCO) that leases them to ScotRail. Stations along the Ayrshire Coast Line and Inverclyde Line underwent platform extension works to allow the use of the longer trains. The trains were specified to have full access for disabled people and to have streamlined end corridor connections. On the unveiling of the first completed veh ...

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 ...

Direct Current
Direct current (DC) is one-directional electric current, flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor (material), conductor such as a wire, but can also flow through semiconductors, electrical insulation, insulators, or even through a vacuum as in electron beam, electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A archaism, term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''Electric current, current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains Electronics, electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Third Rail
A third rail, also known as a live rail, electric rail or conductor rail, is a method of providing electric power to a railway locomotive or train, through a semi-continuous rigid conductor placed alongside or between the rails of a track (rail transport), railway track. It is used typically in a mass transit or rapid transit system, which has alignments in its own corridors, fully or almost fully segregated from the outside environment. Third-rail systems are usually supplied with direct current. Modern tram systems with street running avoid the electrical injury risk of the exposed electric rail by implementing a segmented ground-level power supply, where each segment is electrified only while covered by a vehicle which is using its power. The third-rail system of electrification is not related to the third rail used in dual gauge, dual-gauge railways. The system is generally associated with a low voltage (rarely above 750 V) and is far less used for main lines than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
