TX-2000 Series
The is a dual-voltage electric multiple unit (EMU) train type operated by the Metropolitan Intercity Railway Company on the Tsukuba Express line in the Kanto region of Japan since 2005. Design TX-2000 series trains are capable of operating on both the 1,500 V DC and 20 kV AC sections of the Tsukuba Express, and therefore operate over the full length of the line. (The DC-only TX-1000 series sets are restricted to the Akihabara – Moriya section of the line.) Formation , the fleet consists of 23 six-car sets (51 to 73), consisting of four motored (M) cars and two trailer (T) cars, and formed as follows with car 1 at the Tsukuba (northern) end.

Hitachi A-train
The Hitachi A-train is a family of rail rolling stock built and designed by Hitachi Rail using a common base and construction techniques. The stock is designed to facilitate a number of product life-cycle improvements including ease of manufacture, increased energy efficiency, and recyclability. Description The "A-train" design concept includes several elements. The primary feature is that vehicle car bodies are constructed from double skin aluminium extruded sections, which are friction stir welded, creating a strong body. Other features include hollow, extruded mounting rails on the vehicle body to which modular components are attached.Hitachi's Entry into the European Railway Market - Japan Railway & Transport Review No. 42 (pp.10–16) Initially the A-train family consisted of |

Tsukuba Express
The , or TX, is a Japanese railway line operated by the third-sector company Metropolitan Intercity Railway Company, which links Akihabara Station in Chiyoda, Tokyo and Tsukuba Station in Tsukuba, Ibaraki. The route was inaugurated on 24 August 2005. History The was founded on 15 March 1991 to construct the Tsukuba Express, which was then provisionally called the . The new line was planned to relieve crowding on the Jōban Line operated by East Japan Railway Company (JR East), which had reached the limit of its capacity. However, with the economic downturn in Japan, the goal shifted to development along the line. This was facilitated by the enactment of the Special Measures Law in September 1989 which allowed the expedition of large housing projects as well as the expansion and construction of new and existing railway lines. During the early stages of construction, the construction company (Japan Railway Construction, Transport and Technology Agency, or JRTT) as well as ass ...

Pulse-width Modulation
Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. The longer the switch is on compared to the off periods, the higher the total power supplied to the load. Along with maximum power point tracking (MPPT), it is one of the primary methods of reducing the output of solar panels to that which can be utilized by a battery. PWM is particularly suited for running inertial loads such as motors, which are not as easily affected by this discrete switching, because their inertia causes them to react slowly. The PWM switching frequency has to be high enough not to affect the load, which is to say that the resultant waveform perceived by the load must be as smooth as possible. The rate (or frequency) a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (electrical circuits), topology, to control associated voltage or electric current, 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 f ...

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