JR East
The is a major passenger railway company in Japan and is the largest of the seven Japan Railways Group companies. The company name is officially abbreviated as JR-EAST or JR East in English, and as in Japanese. The company's headquarters are in Yoyogi, Shibuya, Tokyo, and next to the Shinjuku Station. It is listed in the Tokyo Stock Exchange (it formerly had secondary listings in the Nagoya and Osaka stock exchanges), is a constituent of the TOPIX Large70 index, and is also one of the three only Japan Railways Group constituents of the Nikkei 225 index, the other being JR Central and JR West. History JR East was incorporated on 1 April 1987 after being spun off from the government-run Japanese National Railways (JNR). The spin-off was nominally "privatization", as the company was actually a wholly owned subsidiary of the government-owned JNR Settlement Corporation for several years, and was not completely sold to the public until 2002. Following the breakup, JR East ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Induction Motor
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical. Single-phase induction motors are used extensively for smaller loads, such as household appliances like fans. Although traditionally used in fixed-speed service, induction motors are increasingly being used with variable-frequency drives (VFD) in variable-speed service. VFDs offer especially important energy savings opportunities for existing and prospective induction motors in variable-torque centrifugal fan, pump and compressor load applications. Squirrel ...

E531 Series
The is an electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) in Japan. It was introduced by JR East on 9 July 2005 to replace the aging 403 and 415 series EMUs running on the Jōban Line from Ueno Station in Tokyo. The stock is a dual-voltage (1,500 V DC & 20 kV AC) development of the DC-only E231 series suburban EMU design, and can run at speeds of up to in service. Operations * Tōkaidō Main Line (–) * Ueno–Tokyo Line * Jōban Line (–) * Mito Line * Tōhoku Main Line (–) Trains are formed in 10-car (set numbers K401–K426) and 5-car (set numbers K451–K483, K551–K557) sets. 15-car formations are generally run between and . 10- and 5-car sets operate singly north of Tsuchiura, and 5-car sets are used on the Mito Line. 5-car cold weather sets (E531-3000 series) are used on the Tōhoku Main Line between and , to handle the change of electrification from DC to AC just north of Kuroiso.

E231 Series
The is an electric multiple unit (EMU) train type used for commuter and outer-suburban services operated by East Japan Railway Company (JR East) in Japan since 2000. Design Trains were manufactured by Tokyu Car Corporation, Kawasaki Heavy Industries and also at JR East's factory at Niitsu in Niigata Prefecture. The type evolved from the earlier 209 series and E217 series EMUs, with the main visible difference being wider bodies (2,950 mm compared to the 2,800 mm for earlier commuter trains), and the prototype train built in 1998 for trials on the Chūō–Sōbu Line was actually classified 209-950 series, later becoming E231-900 series. Full-production E231-0 series trains were subsequently introduced on the Chūō–Sōbu Line (10-car sets) and Jōban Line (10+5-car sets). Other variants include the 11-car E231-500 series for the Yamanote Line, and the E231-800 series with 2,800 mm wide bodies and end doors for use on Tokyo Metro Tozai Line inter-running serv ...

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 ...

Railway Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a railway vehicle that connects them together to form a train. A variety of coupler types have been developed over the course of railway history. Key issues in their design include strength, reliability, ease of making connections and operator safety. The equipment that connects the couplings to the vehicles is the draft gear or draw gear and these must absorb the stresses of coupling and train acceleration. Nomenclature Compatible and similar couplings or couplers are frequently referred to using widely differing make, brand, or regional names, or nicknames, which can make describing standard or typical designs confusing. Dimensions and ratings noted in these articles are usually of nominal or typical components and systems, though standards and practices also vary widely with railway, region, and era. Buffers and chain The basic type of coupling on railways following the British tradition is the bu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Digital ATC
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 especially com ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

ATS-SN
Automatic train stop or ATS is a system on a train that automatically stops a train if certain situations occur (unresponsive train operator, earthquake, disconnected rail, train running over a stop signal, etc.) to prevent accidents. In some scenarios it functions as a type of dead man's switch. Automatic train stop differs from the concept of Automatic Train Control in that ATS usually does not feature an onboard speed control mechanism. Overview Mechanical systems The invention of the fail-safe railway air brake provided an external means for stopping a train via a physical object opening a valve on the brake line to the atmosphere. Eventually known as ''train stops'' or ''trip stops'', the first mechanical ATS system was installed in France in 1878 with some railroads in Russia following suit using a similar system in 1880. In 1901 Union Switch and Signal Company developed the first North American automatic train stop system for the Boston Elevated Railway. This system was so ...
