IE 8510 Class
The Iarnród Éireann 8500, 8510 and 8520 Classes are three related types of EMU used on the DART network in Dublin, Ireland. The total fleet numbers a total of 17 four-car trains, all of which were constructed by the Tokyu Car Corporation. 8500 Class The 8500 Class were delivered in 2000 and were the first four car units to be used on the DART network. They are numbered in the sequence 860X+850X+850Y+860Y. 850X/850Y units are power cars while 860X/860Y units are unpowered driving trailers. Their interior destination displays and public announcement system has been long turned off. Like all DART units, the 8500 Class are maintained at Fairview depot, and are also stabled at Bray Station. 8510 Class The 8510 Class were delivered in 2001 as three 4-car trains supplementing the original 8500 Class. Vehicles are numbered in the sequence 861X+851X+851Y+861Y. 851X/851Y units are power cars while 861X/861Y units are unpowered driving trailers. The most visible difference between ...

Japan Transport Engineering Company
is a manufacturer of heavy rail cars in Japan, formerly known as . The company is based in Kanazawa-ku, Yokohama, and a member of East Japan Railway Company (JR East) group. J-TREC manufactures rail vehicles not only for JR East and Tokyu Corporation but for other Japanese operators, including various Japan Railways Group companies and international operators as well. Tokyu Car Corporation, the predecessor of J-TREC, was founded on 23 August 1948. Tokyu Car was a licensee of early-generation (early-1960s) stainless-steel commuter EMU train body and related bogie technology from the Budd Company of the United States. Since then, Tokyu Car has specialised in stainless-steel body car technology. On 27 October 2011, Tokyu Car Corporation announced that its rolling stock manufacturing division would be acquired by East Japan Railway Company (JR East), and the company cease operations with effect from 1 April 2012. It is to be subsequently split into two companies, Tokyu Car Enginee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairview DART Depot
Fairview DART depot is a railway depot used for servicing electrical multiple units on the Dublin Area Rapid Transit system. Facilities There is a three road shed, train wash and sidings. It is located just south of Clontarf Road DART station on the Dublin-Belfast railway line. However, maintenance on DART units is also carried out at Inchicore Works. There is no wheel lathe at the depot and as a result, out of service Commuter (29000 Class) DMUs tow DART trains to the Drogheda Commuter depot in order to receive new wheels. Fleet serviced at the depot * 8100 Class * 8500, 8510 and 8520 Classes Driver changes This depot is also used for the change of drivers on the DART line – much to the dissatisfaction of northside commuters, as the depot is 50 metres from the platform at Clontarf Road Station, making it arguably a more logical point at which to change drivers. Recent cost-benefit analysis has determined that this inefficiency costs the Irish economy c. €750,000 per a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IE 8200 Class
The Iarnród Éireann 8200 Class electric multiple units were built for the Dublin Area Rapid Transit (DART). The units were two-car sets, of which there were five. They were numbered in the sequence 820X+840X. 820X units are power cars while 840X units are unpowered driving trailers. History The units first entered service in 2000. The units had operated in multiple with the 8500 and 8510 classes. The five members of this class spent long periods out of service, the most recent being from summer 2007 until March 2008. Following a brief return to service of all coaches with the exception of 8204/8404, all units were withdrawn from service yet again, with Iarnród Éireann citing frequent breakdowns and small seating as their reason for early withdrawal. They were stabled in Fairview DART depot during these periods of being out of service. In 2012 the units were tendered for sale, but were not sold. They remain decommissioned at Inchicore Works, clear of catenary. Fleet de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light-emitting Diode
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Later developments produced LEDs available in visible, ultraviolet (U ...
