Transperth B-series Train
The B-series trains are a class of electric multiple unit built by Downer Rail in Maryborough, Queensland for Transperth Train Operations, Transperth between 2004 and 2019. Design Each set consists of three semi-permanently coupled cars designed to be used in either a three-car or six-car formation. The trains were designed to use AC motors rather than DC traction motors like the previous Transperth A-series train, A-series, and to have a maximum service speed of . In each set, IGBT inverters power eight AC traction motors distributed along the three cars, providing a 66% motorised unit. These trains are similar in design to Queensland Rail's Interurban multiple unit#160 series, IMU160/Suburban multiple unit#260 series, SMU260 EMU, V/Line VLocity DMU, and Adelaide Metro 4000 class EMU trains. The B series trains were originally built concurrently with the V/Line VLocity. History Perth's first electrified trains, the two-car Transperth A-series train, A-series, entered ser ...

Adelaide Metro 4000 Class
The Adelaide Metro 4000 class, also referred to as A-City trains, are electric multiple unit trains built by Bombardier Transportation (later Alstom) in Dandenong, Victoria for the electrified Adelaide rail network. They are the only class of operational electric trains in South Australia, running services on the Gawler, Seaford and Flinders lines. History In the 2008/09 State Budget, it was announced that five out of six of Adelaide's railway lines were to be electrified commencing with the Noarlunga and Gawler lines. This was to have resulted in 58 of the 3000/3100 class railcars being converted to electric operation with the remaining 12 to be retained as diesels for operation on the Belair line. The electrification was scaled back and Bombardier Transportation was awarded a contract to build 22 three-carriage trains for the Adelaide rail network in 2011 instead. The first of these trains were delivered in July 2013, and entered service on 23 February 2014 on the Seafor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V/Line VLocity

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 ...

Scharfenberg Coupler
The Scharfenberg coupler (, abbreviated ''Schaku'') is a commonly used type of fully automatic railway coupling. Designed in 1903 by Karl Scharfenberg in Königsberg, Germany (today Kaliningrad, Russia), the coupler has gradually spread from transit trains to regular passenger service trains, although outside Europe its use is generally restricted to mass transit systems. The ''Schaku'' is superior in many ways to the Janney coupler, AAR (Janney/knuckle) coupler because it also automates electrical and pneumatic connections and disconnections. However, there is no standard for the placement of these electro-pneumatic connections. Some rail operators have placed them on the sides while others have placed them either below or above the mechanical portion of the coupler. Scharfenberg as a technical design principle and brand name Scharfenberg and the abbreviation Schaku are registered trademarks of Voith Patent GmbH. For this reason, only couplings from Voith can use this name. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dynamic Braking
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 ...

Regenerative Brake
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that can be either used immediately or stored until needed. Typically, regenerative brakes work by driving an electric motor in reverse to recapture energy that would otherwise be lost as heat during braking, effectively turning the traction motor into a generator. Feeding power backwards through the system like this allows the energy harvested from deceleration to resupply an energy storage solution such as a battery or a capacitor. Once stored, this power can then be later used to aid forward propulsion. Because of the electrified vehicle architecture required for such a braking system, automotive regenerative brakes are most commonly found on hybrid and electric vehicles. This method contrasts with conventional braking systems, where excess kinetic energy is converted to unwanted and wasted heat due to friction ...
