KTM Class 82
The Class 82 was a type of sub-urban rail electric multiple unit that once operated by Keretapi Tanah Melayu on its KTM Komuter services. Each unit consists of two driving motor cars and a trailer cars. All were retired by 2012 after being replaced by the Class 92. Design The Class 82 was designed with a streamlined sloped head with two high beam lamps concentrated at the center top with two standard headlights at either sides. Route direction is indicated on the front of the train within a confined fluorescent lighted box using a lightly transparent plastic. The Class 82 have two double-leaf pressure plug doors per side each coach. The cab head is designed to be bottom heavy with the bulk of the power transformers and motors located beneath the coach, allowing saloon space to be maximised. The front outer frame is made of heavy carbonized steel which is capable of sustaining high impact. An ARR coupling system is used, which is compatible with all of KTMB's modern rolling sto ...

Pantograph (transport)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

KTM Class 92
The Class 92 is a type of electric multiple unit operated by Keretapi Tanah Melayu on its KTM Komuter services. A total of 38 sets were built by CSR Zhuzhou of China, in 6-car formations. History The Class 92 was procured under a Malaysian Government initiative, National Key Result Area (NKRA) to reduce congestion and improve public transport with a specific RM2 billion allocation to KTMB to improve commuter rail efficiency. A sum of RM 1.894 billion was spent to procure these trains, with the remainder being spent on the improvement of signaling along the Putra-Mid Valley stretch and a ticketing system upgrade. The first EMU was delivered on 23 September 2011 and was expected to operate in revenue service by late December 2011. However, delays in testing led to the subsequent postponement of launch. On 8 March 2012, 4 sets commenced operation. All 38 sets were in revenue service by July 2012. Features Designed for low dwell times and high passenger seating capacity, the t ...

KTM Komuter
KTM Komuter is a commuter rail system in Malaysia operated by Keretapi Tanah Melayu (KTM). It was introduced in 1995 to provide local rail services in Kuala Lumpur and the surrounding Klang Valley suburban areas. Services were later expanded to other parts of Malaysia with the introduction of the Northern and Southern sectors. The service uses air-conditioned electric multiple units in 3 and 6 car formations. KTM Komuter contributed RM146.2 million to group revenue in 2017, carrying a total of 37.235 million passengers. The total number of passengers travelling with KTM Komuter in 2017 shows a decrease of 10.2%. This can be attributed to reduced service frequency due to the ongoing Klang Valley Double Tracking (KVDT) rehabilitation project. Network Current Network Central Sector KTM Komuter's 287 km (109 mi) network in the Central Sector mainly covers the Klang Valley. It has 53 stations. It consists of two cross-city routes, namely the Port Klang Line (Tanjung Malim to ... [...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 ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keretapi Tanah Melayu
Keretapi Tanah Melayu Berhad (KTMB) (Jawi: كريتاڤي تانه ملايو برحد) or Malayan Railways Limited is the main rail operator in Peninsular Malaysia. The railway system dates back to the British colonial era, when it was first built to transport tin. Previously known as the Federated Malay States Railways (FMSR) and the Malayan Railway Administration (MRA), Keretapi Tanah Melayu acquired its current name in 1962. The organisation was corporatised in 1992, but remains wholly owned by the Malaysian government. History In 1948, the FMSR was renamed the Malayan Railways. The railways had been devastated by the Japanese invasion of Malaya, and efforts were taken to rebuild the two main lines, but many branch lines were abandoned in the process. The MR began to modernize the equipment with the ordering of diesel locomotives and railcars to replace steam hauled services, and the first diesel locomotive entered service in 1957. The railcars entered service in 196 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Variable-frequency Drive
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, to control associated voltage or 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 for fans. However, the global market penetration fo ...
