521 Series
The is a dual-voltage AC/DC outer-suburban electric multiple unit (EMU) train type operated by West Japan Railway Company (JR West) and third-sector railway operators IR Ishikawa Railway and Ainokaze Toyama Railway on local services in the Fukui and Kanazawa areas since November 2006. In March 2024, Hapi-line Fukui acquired some sets after taking over the section of the Hokuriku Main Line within Fukui Prefecture from JR West. Design The 521 series was the first dual-voltage suburban EMU type to be built for JR West. The body of the first two batches was based on the 223-5000 series suburban EMU design, with the same WMT102C traction motors. The sets are able to be used on ''wanman'' driver-only operation services.

Variable Frequency Drive
A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the input electricity. Depending on its topology, it controls the associated voltage or current variation., quote is per definition on p. 4 of NEMA Standards Publication ICS 7.2-2021. VFDs are used in applications ranging from small appliances to large compressors. Systems using VFDs can be more efficient than hydraulic systems, such as in systems with pumps and damper control for fans. Since the 1980s, power electronics technology has reduced VFD cost and size and has improved performance through advances in semiconductor switching devices, drive topologies, simulation and control techniques, and control hardware and software. VFDs include low- and medium- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Obama Line
The is a railway line on the Sea of Japan coast of central Japan. It is operated by West Japan Railway Company (JR West). The long single track railway connects Tsuruga Station on the Hokuriku Main Line in Tsuruga, Fukui Prefecture and Higashi-Maizuru Station on the Maizuru Line in Maizuru, Kyoto Prefecture. The city of Obama and the towns of Mihama, Wakasa, Ōi and Takahama are located in the central section of the line. History The Tsuruga - Tomura section opened in 1917, and the line was then extended westward to Obama in 1918, Wakasa-Takahama in 1921 and connected to the Maizuru Line at Higashi-Maizuru the following year. Freight services between Tsuruga and Mitsumatsu ceased in 1997. The line was electrified on March 15, 2003.

Driver-only Operation
One-person operation (OPO), also known as driver-only operation (DOO), one-man operation (OMO), single person train operation (SPTO), or one-person train operation (OPTO), similarly to driver-controlled operation, is operation of a train, bus, or tram by the driver alone, without a conductor. On one-person operated passenger trains, the engineer must be able to see the whole train to make sure that all the doors are safe for departure. On curved platforms a CCTV system, mirror or station dispatch staff are required. Although extra infrastructure such as cameras and mirrors might require additional investment, one-person operation is usually faster and cheaper to implement than automatic train operation, requiring a smaller investment in, for example, platform intruder detection systems and track protection (fencing, bridge-caging, CCTV etc.). In some cases, one-person operation can be seen as an intermediate step towards automatic train operation. While European freight tr ...

223 Series
The is a suburban electric multiple unit (EMU) train type operated by the West Japan Railway Company (JR-West) in the Kansai region, Chūgoku region and Shikoku region of Japan. Multiple batches of the model have been built with varying differences (particularly motor output control), although the overall general appearance remains similar. Design of the rolling stock was an improved adaptation of the 221 series, with three pairs of doors per side per car and a transverse seating layout. Production of the train type first began in 1993. Variants 223-0, 223-2500 series The first model (223–0) was delivered earlier than expected, and saw introduction into service on 1 April 1994, on the Hanwa Line. On 4 September of the same year, it began serving the Kansai Airport Line Rapid Service as Kansai International Airport opened. The train was initially fitted with luggage racks, for passengers travelling to/from the airport. A 1 + 2 seating configuration has been adopted to allo ...

Public–private Partnership
A public–private partnership (PPP, 3P, or P3) is a long-term arrangement between a government and private sectors, private sector institutions.Hodge, G. A and Greve, C. (2007), Public–Private Partnerships: An International Performance Review, Public Administration Review, 2007, Vol. 67(3), pp. 545–558 Typically, it involves private capital financing government projects and services up-front, and then drawing revenues from taxpayers and/or users for profit over the course of the PPP contract. Public–private partnerships have been implemented in Public–private partnerships by country, multiple countries and are primarily used for infrastructure projects. Although they are not compulsory, PPPs have been employed for building, equipping, operating and maintaining schools, hospitals, transport systems, and water and sewerage systems. Cooperation between private actors, corporations and governments has existed since the inception of sovereign states, notably for the purpose ...

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. However, electrically powered single-unit railcars are also generally classed as EMUs. The vast majority of EMUs are passenger trains but versions also exist for carrying mail. EMUs are popular on intercity, commuter, and suburban rail networks around the world due to their fast acceleration and pollution-free operation, and are used on most rapid-transit systems. 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 ...

Regenerative Braking
Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that can be either used immediately or stored until needed. Typically, regenerative brakes work by driving an electric motor in reverse to recapture energy that would otherwise be lost as heat during braking, effectively turning the traction motor into a generator. Feeding power backwards through the system like this allows the energy harvested from deceleration to resupply an energy storage solution such as a battery or a capacitor. Once stored, this power can then be later used to aid forward propulsion. Because of the electrified vehicle architecture required for such a braking system, automotive regenerative brakes are most commonly found on hybrid and electric vehicles. This method contrasts with conventional braking systems, where excess kinetic energy is converted to unwanted and wasted heat due to friction i ...

Electronically Controlled Pneumatic Brakes
Electronically controlled pneumatic brakes are a type of railway braking systems. Overview Traditional train braking systems use pneumatic valves to control and generate brake applications on the cars along the length of the train. In general, this conventional system consists of a brake pipe that runs the length of the train which supplies air to reservoirs mounted on each of the cars. When the brake pipe and car components are charged with air, the brakes release. When the engineer needs to make a brake application, control valves in the locomotive reduce the brake pipe pressure. As the brake pipe pressure is reduced, the service portions on each car divert air from their reservoirs to their brake cylinders. To release the brakes, the engineer charges the brake pipe. This method of controlling the brakes on freight and passenger cars has remained virtually unchanged since its invention by George Westinghouse in 1868. The conventional braking system suffers from many weakness ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
