High Capacity Metro Trains
The High Capacity Metro Train (HCMT) is a type of electric multiple unit (EMU) train for use by Metro Trains Melbourne on the Melbourne rail network. The first train set entered service on 27 December 2020 and will become the primary rolling stock used in the Metro Tunnel when it opens in 2025. The HCMTs carry around 1,400 passengers in seven carriages, running on Melbourne's overhead catenary system, and are currently the most advanced trains in the Metro Trains fleet. A consortium of investors and rail companies are constructing the trains in China and Australia via a contract with the Victorian Government, in addition to upgrade works necessary for the operation of the trains. History Background The previous major procurement of rolling stock for the Melbourne rail network occurred in 2002, when franchisees M>Train and Connex ordered 62 Siemens Nexas and 58 X'Trapolis 100 trains respectively, as part of their franchise agreements to replace the older Hitachi trains. ...

Werribee Railway Line
The Werribee railway line is a commuter rail passenger train service in Melbourne, Australia, operating between Werribee in the western suburbs to Flinders Street in the central business district. The line traverses the flat plains of Melbourne's western suburbs, and after leaving Footscray, has no significant earthworks. The area around the outer end of the line has seen significant residential growth in recent years, resulting in strong patronage growth. It is part of the Melbourne metropolitan rail network operated by Metro Trains. Infrastructure The Werribee line consists of multiple tracks, shared with other lines, from the City Loop until South Kensington, after which it becomes double track. From Newport South Junction, which is about a kilometre after Newport, the two tracks are signalled for bi-directional operation, although it is very rare for trains to use the possibility of right-hand running. About one and a half kilometres from Newport South, the Altona b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Three-phase Electric Power
Three-phase electric power (abbreviated 3φ) is a common type of alternating current used in electricity generation, transmission, and distribution. It is a type of polyphase system employing three wires (or four including an optional neutral return wire) and is the most common method used by electrical grids worldwide to transfer power. Three-phase electrical power was developed in the 1880s by multiple people. Three-phase power works by the voltage and currents being 120 degrees out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency. A three-wire three-phase circuit is usually more economical than an equivalent two-wire single-phase circuit at the same line to ground voltage because it uses less conductor material to transmit a given amount of electrical power. Three-phase power is mainly used directly to power large induction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victorian Government
The Victoria State Government, also referred to as just the Victorian Government, is the state-level authority for Victoria, Australia. Like all state governments, it is formed by three independent branches: the executive, the judicial, and the parliament. As a parliamentary constitutional monarchy, the State Government was first formed in 1851 when Victoria first gained the right to responsible government. The Constitution of Australia regulates the relationship between the Victorian Government and the Australian Government, and cedes legislative and judicial supremacy to the federal government on conflicting matters. The Victoria State Government enforces acts passed by the parliament through government departments, statutory authorities, and other public agencies. The Government is formally presided over by the Governor, who exercises executive authority granted by the state's constitution through the Executive Council, a body consisting of senior cabinet ministers. In re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metro Tunnel
The Metro Tunnel (previously known during planning as the Melbourne Metro Rail Project) is a metropolitan rail infrastructure project currently under construction in Melbourne, Australia. It includes the construction of twin 9-kilometre rail tunnels between South Kensington (north west of the Melbourne central business district) and South Yarra (in the south east) with five new underground stations. The tunnel will connect the Pakenham and Cranbourne lines with the Sunbury line, creating a new cross-city line that bypasses Flinders Street station and the City Loop. From 2029 the line will also serve Melbourne Airport via a new branch line west of Sunshine station. The project will allow for the operational separation of various existing lines on Melbourne's rail network and increase the capacity of the system to allow for metro-style frequencies. The Metro Tunnel project includes the installation of high-capacity signalling and platform-screen doors. With the delivery of oth ...

Melbourne Rail Network
The Melbourne rail network is a passenger and freight train system in the city of Melbourne, Victoria, Australia. The metropolitan passenger rail network is centred on the Melbourne CBD and consists of 222 stations across 16 lines, which served a ridership of 99.5 million over the year 2021-2022. It is the core of the larger Victorian railway network, with links to both intrastate and interstate systems. The first steam train in Australia commenced service in Melbourne in 1854, with the metropolitan network having grown over the last two centuries to cover much of the city. Metro Trains Melbourne operates the Melbourne metropolitan railway network under franchise from the Government of Victoria, while the government-owned entity V/Line operates trains from Melbourne across regional Victoria. The metropolitan network is a suburban rail system designed to transport passengers from Melbourne's suburbs into the Melbourne central business district (CBD) and associated city loo ...

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 ...

Communications-based Train Control
Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This makes railway traffic management safer and more efficient. Metros (and other railway systems) are able to reduce headways while maintaining or even improving safety. A CBTC system is a "continuous, automatic train control system utilizing high-resolution train location determination, independent from track circuits; continuous, high-capacity, bidirectional train-to-wayside data communications; and trainborne and wayside processors capable of implementing automatic train protection (ATP) functions, as well as optional automatic train operation (ATO) and automatic train supervision (ATS) functions," as defined in the IEEE 1474 standard.1474.1–1999 – IEEE Standard for Communications-Base ...
