KTM Class 81
The Class 81 is the first and oldest type of electric multiple unit introduced by Keretapi Tanah Melayu for its KTM Komuter service. 18 sets were designed by Hunslet TPL and built by Ganz Works. The Class 81 currently operates in a fixed 3-car formation for its regular service. The middle coach is exclusively for women and children. The KTM Class 81 design is derived from the British Rail Class 323, with the main alteration being that it has single leaf swing-plug doors instead of a double leaf type. Description The EMUs were built from 1994 to 1995 and entered service on 3 August 1995. The EMUs were the first electric trains of any kind in KTM's history. They operate in multiple-unit formation, The EMUs were state-of-the-art, with remote-controlled pneumatic doors, Automatic Train Protection (ATP), train data recorder, wheel-slip control, GTO/IGBT traction electronics and regenerative braking, and ran from overhead catenary An overhead line or overhead wire is an electr ...

Ganz Works
The Ganz Works or Ganz ( or , ''Ganz companies'', formerly ''Ganz and Partner Iron Mill and Machine Factory'') was a group of companies operating between 1845 and 1949 in Budapest, Hungary. It was named after Ábrahám Ganz, the founder and the manager of the company. It is probably best known for the manufacture of tramcars, but was also a pioneer in the application of Three-phase AC railway electrification, three-phase alternating current to electric railways. Ganz also made ships (''Ganz Danubius''), bridge steel structures (''Ganz Acélszerkezet'') and high-voltage equipment (''Ganz Transelektro''). In the early 20th century the company experienced its heyday, it became the third largest industrial enterprise in Kingdom of Hungary after the ''Manfréd Weiss Steel and Metal Works'' and the ''MÁVAG'' company. Since 1989, various parts of ''Ganz'' have been taken over by other companies. History Before 1919, the company built ocean liners, dreadnought type battleships and su ...

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 ...

Jenbacher
INNIO Jenbacher designs and manufactures gas engines and cogeneration modules in the Austrian town of Jenbach in Tyrol. It is part of the INNIO portfolio of products and is one of their gas engine technologies; the other being Waukesha Engines. Jenbacher emerged from the former Jenbacher Werke, which was founded in 1959 and manufactured gas and diesel engines, and locomotives. The company was bought out by General Electric in 2003. In November 2018 the company became part of INNIO as part of an acquisition of Advent International and was renamed INNIO Jenbacher GmbH & Co. OHG. History Although the company itself has a relatively short history, its origins go far back. In 1487, a mine and foundry was founded by the Fugger family. In 1657, all Fugger properties in Tyrol were taken over by the state. Due to exhaustion of the copper and silver deposits, the mine changed its focus to iron. The company was acquired by Julius and Theodor Reitlinger in 1881. In 1909, the mine ran out o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Multiple-unit
A multiple-unit train or simply multiple unit (MU) is a self-propelled train composed of one or more carriages joined together, which when coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control. Although multiple units consist of several carriages, single self-propelled carriages – also called railcars, rail motor coaches or railbuses – are in fact multiple-units when two or more of them are working connected through multiple-unit train control (regardless if passengers can walk between the units or not). History Multiple-unit train control was first used in electric multiple units in the 1890s. The Liverpool Overhead Railway opened in 1893 with two-car electric multiple units, controllers in cabs at both ends directly controlling the traction current to motors on both cars. The multiple-unit traction control system was developed by Frank Sprague and first applied and tested on the South Side Elevated Railroad (now p ...

British Rail Class 323
The British Rail Class 323 are electric multiple unit (EMU) passenger trains built by Hunslet Transportation Projects and Holec. All 43 units were built from 1992 through to 1995, although mock-ups and prototypes were built and tested in 1990 and 1991. Entering service in 1994, the 323s were among the last trains to enter service with British Rail before its privatisation in the mid-1990s. The units were designed to operate on inner-suburban commuter lines in and around Birmingham and Manchester with swift acceleration and high reliability. Of the 43 sets built, 26 are in operation with West Midlands Trains and 17 with Northern Trains. In 2023 the West Midlands Trains sets will start to be replaced by new Class 730 EMUs, and 34 sets will be operated by Northern Trains. The units are known for the distinctive sounds that can be heard during acceleration or deceleration. These sounds are generated by the traction electronics. Background In 1990 the Regional Railways sector of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
