EMU600 Series
The EMU600 series is a series of electric multiple unit passenger trains operated by Taiwan Railways Administration (TRA). The trains are built as local trains and are used throughout the island’s rail network. History With the electrification of the Yilan line and the North-link line in the early 2000s, the TRA faced a shortage of electric passenger trains. Therefore, in 1999, the TRA contracted South Korean manufacturer KOROS to build 56 more cars divided into 14 trainsets. The first two trainsets were shipped to Taiwan on October 3, 2000. When KOROS merged with other companies in 2002 to form Hyundai Rotem, the new company continued to produce the trains. The last two trainsets (numbered 613 and 614) were produced in Taiwan by Tang Eng Iron Works. The trains entered service on 11 October 2002. Features The EMU600 series runs in four-car units in the following order: a motorized car with the cab (EMC), an unmotorized car with a pantograph (EP), an unmotorized car (ET) ...

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 ex ...

Electric Multiple Units Of Taiwan
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

United Daily News
''United Daily News'' (UDN; ) is a newspaper published in Taiwan. It is considered to support the pan-Blue Coalition in its editorials. History UDN was founded in 1951 by Wang Tiwu as a merger of three newspapers, ''Popular Daily'' (全民日報), ''National'' (民族報), and the ''Economic Times'' (經濟時報). The three newspapers formally merged in 1953. In terms of political orientation, the ''United Daily News'' is regarded as taking an editorial line that supports the pan-Blue Coalition. Before Taiwan democratized, it was an opponent of political reform; in the years since Taiwan has democratized, it has advocated policies encouraging cooperation with the mainland. It is the third-biggest newspaper in Taiwan, ranking after the '' Liberty Times'' and the '' Apple Daily''. The evening edition of the paper, the ''United Evening News'', was first published on February 22, 1968. The evening paper shut down after publishing its final issue on June 1, 2020. Contents UDN ...

Accessibility is the design of products, devices, services, vehicles, or environments so as to be usable by people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers). Accessibility can be viewed as the "ability to access" and benefit from some system or entity. The concept focuses on enabling access for people with disabilities, or enabling access through the use of assistive technology; however, research and development in accessibility brings benefits to everyone. Accessibility is not to be confused with usability, which is the extent to which a product (such as a device, service, or environment) can be used by specified users to achieve specified goals with effectiveness, efficiency, convenience, or satisfaction in a specified context of use. Accessibility is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gate Turn-off Thyristor
A gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (.e.g. 1200V AC) semiconductor device. It was invented by General Electric. GTOs, as opposed to normal thyristors, are fully controllable switches which can be turned on and off by their gate lead. Device description Normal thyristors ( silicon-controlled rectifiers) are not fully controllable switches (a "fully controllable switch" can be turned on and off at will). Thyristors can only be turned on using the gate lead, but cannot be turned off using the gate lead. Thyristors are switched on by a gate signal, but even after the gate signal is de-asserted (removed, reverse biased), the thyristor remains in the on state until a turn-off condition occurs (which can be the application of a reverse voltage to the terminals or a decrease of the forward current below a certain threshold value known as the "holding current"). Thus, a thyristor behaves like a normal semiconductor diode after it is turn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insulated-gate Bipolar Transistor
An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch, which, as it was developed, came to combine high efficiency and fast switching. It consists of four alternating layers (P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) gate structure. Although the structure of the IGBT is topologically the same as a thyristor with a "MOS" gate ( MOS-gate thyristor), the thyristor action is completely suppressed, and only the transistor action is permitted in the entire device operation range. It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs), electric cars, trains, variable-speed refrigerators, lamp ballasts, arc-welding machines, induction hobs, and air conditioners. Since it is designed to turn on and off rapidly, the IGBT can synthesize complex waveforms with pulse-width modulation and low-pass filters, so it is also used in switchin ...

Railway Electric Traction
Railway electric traction describes the various types of locomotive and multiple units that are used on electrification systems around the world. History Railway electrification as a means of traction emerged at the end of the nineteenth century, although experiments in electric rail have been traced back to the mid-nineteenth century. Thomas Davenport, in Brandon, Vermont, erected a circular model railroad on which ran battery-powered locomotives (or locomotives running on battery-powered rails) in 1834. Robert Davidson, of Aberdeen, Scotland, created an electric locomotive in 1839 and ran it on the Edinburgh-Glasgow railway at 4 miles per hour. The earliest electric locomotives tended to be battery-powered. In 1880, Thomas Edison built a small electrical railway, using a dynamo as the motor and the rails as the current-carrying medium. The electric current flowed through the metal rim of otherwise wooden wheels, being picked up via contact brushes. Electrical traction offere ...

Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products. The biological cleanability of stainless steel is superior to both aluminium and copper, having a biological cleanability comparable to glass ...

Cab (locomotive)
The cab, crew compartment or driver's compartment of a locomotive, or a self-propelled rail vehicle, is the part housing the train driver, fireman or secondman (if any), and the controls necessary for the locomotive or self-propelled rail vehicle's operation. Cab locations On steam locomotives, the cab is normally located to the rear of the firebox, although steam locomotives have sometimes been constructed in a cab forward or camelback configuration. The cab, or crew or driver's compartment of a diesel or electric locomotive will usually be found either inside a cabin attached to a hood unit or cowl unit locomotive, or forming one of the structural elements of a cab unit locomotive. The former arrangement is now the norm in North America for all types of diesel or electric locomotives. In Europe, most modern locomotives are cab units with two cabs, one at each end. However, the locomotives powering some high speed European trains are normally cab units with one cab, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North-link Line
The North-Link Line () is the central section of the Eastern Line of the Taiwan Railways Administration. The length of its mainline is 79.2 km, and there is a 7.4 km long branch between Beipu and Hualien Port. History The high mountains and cliffs in eastern Taiwan, between Yilan and Hualien, is a major barrier to the transportation between northern Taiwan and eastern Taiwan. The highway was narrow and dangerous. Ferry service between Keelung and Hualien was an overnight trip. Thus in 1973 the construction of North-link line started. The line branched from Yilan line at Nan Sheng Hu in Su'ao, traveling through mountains and valleys with 91 tunnels and 16 bridges, and ended at a newly constructed Hualien Station. The line was completed in 1979 and was almost immediately overloaded in passenger and freight services. Despite Taiwan Railways Administration continued upgrading signals, tracks, and rolling stock of the line, the great demand could not be fulfilled. The lin ...

Yilan Line
The Yilan Line () is the northern section of the Eastern Line of the Taiwan Railways Administration in Taiwan. It has a length of 95 km. History This railroad was completed in 1924 as the Giran-sen during Imperial Japanese rule over Taiwan. It was expanded to two tracks in the early 1980s. In 2000, it was electrified between Badu and Luodong, while the remaining part was completed in 2003. On 4 December 2020, a landslide buried a section of the line between Houtong and Ruifang Station in Ruifang District, resulting in the rail service disruption along the line. Emergency work was then carried out to remove the 10,000 m3 debris and to restore the 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 equipm .... On 14 December, the line was fully reopened for service. Stati ...
