Automatic Train Control
Automatic train control (ATC) is a general class of train protection systems for railways that involves a speed control mechanism in response to external inputs. For example, a system could effect an emergency brake application if the driver does not react to a signal at danger. ATC systems tend to integrate various cab signalling technologies and they use more granular deceleration patterns in lieu of the rigid stops encountered with the older automatic train stop (ATS) technology. ATC can also be used with automatic train operation (ATO) and is usually considered to be the safety-critical part of a railway system. Over time, there have been many different safety systems labelled as "automatic train control". The first experimental apparatus was installed on the Henley branch line in January 1906 by the Great Western Railway, although it would now be referred to as an automatic warning system (AWS) because the driver retained full command of braking. The term is especial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Multiple Units Of Japan
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 po ...

Yokohama Municipal Subway
is the rapid transit network in the city of Yokohama, Japan, south of Tokyo in Kanagawa pref. It is operated by Yokohama City Transportation Bureau as two lines, though three continuous lines exist. Lines The Yokohama Municipal Subway consists of three lines: Line 1, Line 3 and 4. Line 1 and 3 are operated as a single line, nicknamed the Blue Line. Line 4 is nicknamed the Green Line. Upon the addition to the network of this line on March 30, 2008, the Blue Line and Green Line monikers came into official use. Transfer between the Blue and Green Line is possible at Center-Kita and Center-Minami Stations. Feeder bus services from western Kawasaki City area run to Azamino Station. The "missing" Line 2 was planned to run from Kanagawa-Shinmachi Station via Yokohama Station to Byobugaura Station. The line was previously considered as a bypass line for easing congestion on the Keikyū Main Line, however, the line deemed unnecessary after the Keikyu Line increased it ...

VVVF
A variable-frequency drive (VFD) is a type of motor drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and, depending on topology, to control associated voltage or current variation., quote is per definition on p. 4 of NEMA Standards Publication ICS 7.2-2021. VFDs may also be known as 'AFDs' (adjustable-frequency drives), 'ASDs' (adjustable-speed drives), 'VSDs' (variable-speed drives), 'AC drives', 'micro drives', 'inverter drives' or, simply, 'drives'. VFDs are used in applications ranging from small appliances to large compressors. An increasing number of end users are showing greater interest in electric drive systems due to more stringent emission standards and demand for increased reliability and better availability. Systems using VFDs can be more efficient than those using throttling control of fluid flow, such as in systems with pumps and damper control for fans. However, the global market penetration ...

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 ...

Kawasaki Heavy Industries Rolling Stock Company
is the rolling stock manufacturing subsidiary of Kawasaki Heavy Industries. Since beginning operations in 1906, the company has produced more than 90,000 railroad cars. Products As indicated by the company name, the company mainly produces railroad vehicles. Recently Kawasaki has received orders from customers in foreign countries, including Ireland and the United States. All products manufactured for the US rail market are sold through Kawasaki Rail Car Inc., another division of Kawasaki Heavy Industries. An assembly plant in Lincoln, Nebraska produces fully completed cars and "knocked down" cars. Because of substantial sales to the New York City Subway and various commuter lines, an additional assembly plant was established in Yonkers, New York in 1986 for final assembly of cars built in Lincoln. In November 2020, Kawasaki Heavy Industries announced that it would spin off some of its businesses, including the rolling stock division from October 2021. Japan Railways ...

Yokohama Municipal Subway Blue Line
The is a rapid transit line serving Yokohama in Kanagawa Prefecture, Japan. It is the longer of the two lines in the Yokohama Municipal Subway system operated by Yokohama City Transportation Bureau, and is the second-longest subway line in Japan at in length, surpassed only by the long Toei Oedo Line in Tokyo. The Blue Line is divided into two operating segments: Line 3 from in Aoba-ku, Yokohama to , and Line 1 from Kannai to in Fujisawa. Local and rapid services operate continuously on both lines 1 and 3 as a single service. Following the opening of the Green Line on 30 March 2008, the line was nicknamed the "Blue Line". The line color is blue and the line symbol used in the station numbering is B. Operations Rapid Rapid trains stop at all stations from Shonandai to Totsuka, and from Nippa to Azamino.

Yokohama Municipal Subway Blue Line Symbol
is the second-largest city in Japan by population and the most populous municipality of Japan. It is the capital city and the most populous city in Kanagawa Prefecture, with a 2020 population of 3.8 million. It lies on Tokyo Bay, south of Tokyo, in the Kantō region of the main island of Honshu. Yokohama is also the major economic, cultural, and commercial hub of the Greater Tokyo Area along the Keihin Industrial Zone. Yokohama was one of the cities to open for trade with the West following the 1859 end of the policy of seclusion and has since been known as a cosmopolitan port city, after Kobe opened in 1853. Yokohama is the home of many Japan's firsts in the Meiji period, including the first foreign trading port and Chinatown (1859), European-style sport venues (1860s), English-language newspaper (1861), confectionery and beer manufacturing (1865), daily newspaper (1870), gas-powered street lamps (1870s), railway station (1872), and power plant (1882).
