A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU.
A multiple-unit train is a self-propelled train composed of one or more carriages joined, which if coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control.
Keretapi Tanah Melayu Berhad (KTMB) or Malayan Railway Limited, colloquially referred to simply as KTM, 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) the Malayan Railway Administration (MRA), and the Malayan Railway, Keretapi Tanah Melayu acquired its current name in 1962. The organisation was corporatised in 1992, but remains wholly owned by the Malaysian government.
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.
In rail transport, head-end power (HEP), also known as electric train supply (ETS), is the electrical power distribution system on a passenger train. The power source, usually a locomotive at the front or 'head' of a train, provides the electricity used for heating, lighting, electrical and other 'hotel' needs. The maritime equivalent is hotel electric power. A successful attempt by the London, Brighton and South Coast Railway in October 1881 to light the passenger cars on the London to Brighton route heralded the beginning of using electricity to light trains in the world.
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not.
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.
A control car, cab car, control trailer, or driving trailer is a non-powered rail vehicle from which a train can be operated. As dedicated vehicles or regular passenger cars, they have one or two driver compartments with all the controls and gauges required to remotely operate the locomotive, including exterior locomotive equipment such as horns, bells, ploughs, and lights. They also have communications and safety systems such as GSM-R or European Train Control System (ETCS). Control cars enable push-pull operation when located on the end of a train opposite its locomotive by allowing the train to reverse direction at a terminus without moving the locomotive or turning the train around.
The Kawasaki Railcar Manufacturing Company is the Japanese rolling stock manufacturing subsidiary of Kawasaki Heavy Industries. Since beginning operations in 1906, the company has produced more than 90,000 railroad cars.
The Sentul Komuter station is a Malaysian commuter train station formerly known as Sentul railway station and is located in the east side of and named after Sentul, Kuala Lumpur. Since 2015, the station has been on the Seremban Line of the KTM Komuter train services. For a long time, this station served as the northern terminus of the Sentul-Port Klang route until the line was extended to Batu Caves, when the station continued to be on the Batu Caves-Port Klang Line until the route change in December 2015 to accommodate the Klang Valley Double Tracking upgrade.
The Pioneer III railcar was a short/medium-distance coach designed and built by the Budd Company in 1956 with an emphasis on weight savings. A single prototype was built, but declines in rail passenger traffic resulted in a lack of orders so Budd re-designed the concept as an electric multiple unit (m.u.). Six of the EMU coach design were purchased by the Pennsylvania Railroad with the intention of using them as a high-speed self-contained coach that could be used for long-distance commuter or short-distance intercity travel in the Northeast U.S. The 6 production Pioneer III units were the first all-stainless-steel-bodied EMU railcar built in North America and, at 90,000 pounds (41,000 kg), the lightest.
The Seremban railway station is a Malaysian railway station located in the heart of Seremban, the capital of the state of Negeri Sembilan. The station is named after the city.
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 in 1993-1994.
The Class 83 is a type of electric multiple unit operated by Keretapi Tanah Melayu on its KTM Komuter services. 22 sets were built by Hyundai Precision and Marubeni of South Korea and Japan respectively, in 3-car formations.
The KTM ETS, commercially known as ETS, is an inter-city higher-speed rail service in Malaysia operated by Keretapi Tanah Melayu (KTM). The KTM ETS is the second electric train service to be operated by the Malaysian railway company after KTM Komuter, and the second inter-city rail service after KTM Intercity.
PT Industri Kereta Api (Persero), abbreviated as INKA, is an Indonesian state-owned rolling stock manufacturer.
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.
The Class 91 is a type of electric multiple unit currently operating on Keretapi Tanah Melayu's Electric Train Service (ETS) since 2009. KTMB purchased a total of 5 sets worth RM 240 million from a joint venture between South Korea's Rotem Co. and Japan Mitsubishi Electric Corp in 2008. Each set has six coaches.
The KTM Batu Caves–Pulau Sebang Line, formerly known as the Seremban Line is one of the three KTM Komuter Central Sector lines provided by Keretapi Tanah Melayu. Its electric trains run between Batu Caves and Pulau Sebang/Tampin. Prior to 15 December 2015, the northern terminus of this line was Rawang.
The KTM Class 61 is a diesel multiple unit operated by Keretapi Tanah Melayu for KTM Intercity services on non electrified sections of the KTM West Coast railway line and the KTM East Coast railway line.
