E233 Series
The is a commuter and suburban electric multiple unit (EMU) train type developed by East Japan Railway Company (JR East) from the earlier E231 series and the E531 series design. The first train was introduced in December 2006 for use on the Chūō Line (Rapid), followed by the E233-1000 series variant in 2007 for use on the Keihin–Tōhoku and Negishi lines, the E233-3000 series outer-suburban variant in December 2007 for use on the Tōkaidō Main Line, and narrow-bodied E233-2000 series variant for Jōban Line and Tokyo Metro Chiyoda Line through services. Further variants were built for use on the Keiyō Line, Yokohama Line, Saikyō Line, and Nambu Line. Design The E233 series features two identical sets of main equipment in case of failure. This is the first JR East stock to feature such backup measures. The E233 series provides for better accessibility for the disabled, and is designed to be more comfortable to ride overall than previous stock. The height between th ...

207-900 Series
The or 207–900 series (207系900番台) was a commuter electric multiple unit (EMU) train type introduced in 1986 by Japanese National Railways (JNR) and operated by East Japan Railway Company (JR East) on through services between the Joban Line and Tokyo Metro Chiyoda Line. Only one 10-car set was built, which was withdrawn in December 2009. Design Based on the earlier 205 series design, the 207-900 series was a prototype built as the first VVVF-controlled EMU operated by JNR. The 207 series built later by JR West bears no relation to this train. The train used adjustable voltage/adjustable frequency (AVAF) inverters and induction motors using gate turn-off thyristor (GTO) components. Formation The sole 10-car set, numbered "71", was formed as follows, with car 1 at the Yoyogi-Uehara end and car 10 at the Toride end.

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 ...

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] |

Railway Coupling
A coupling (or a coupler) is a mechanism typically placed at each end of a rolling stock, 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.

E231-1000 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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Regenerative Brake
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In this mechanism, the electric traction motor uses the vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat. This method contrasts with conventional braking systems. In those systems, the excess kinetic energy is converted to unwanted and wasted heat due to friction in the brakes, or with rheostatic brakes, where the energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can significantly extend the life of the braking system as the mechanical parts will not wear out quickly. General principle The most common form of regenerative brake involves an electric motor functioning as an electric generator. In elect ...
