MTrans International Limited
Scomi Rail, formerly MTrans and Monorail Malaysia, was a Malaysian rail system manufacturer specializing in monorails. A subsidiary of Scomi Group, the company was one of the world's three leading providers of monorail systems, and one of only four globally recognized integrated monorail system providers, meaning that apart from manufacturing rolling stock, it also provided equipment like communication systems, electro-mechanical systems and services such as system integration and project management. In 2019 Scomi Rail was placed in receivership and it is no longer selling its monorail system. History In 1997, the Monorail Malaysia project started as the Kuala Lumpur Monorail project. The Asian Economic Crisis of 1998 almost derailed the project completely, due to a huge increase in the price of the Japanese-built imported trains caused by the devaluation of the Malaysian Ringgit, forcing the government to look at alternative solutions. In 1998, the decision was made to cancel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Klang Valley
Klang Valley ( ms, Lembah Klang; zh, 巴生谷; ) is an urban conglomeration in Malaysia that is centered in the federal territories of Kuala Lumpur and Putrajaya, and includes its adjoining cities and towns in the state of Selangor. It is conterminous with Greater Kuala Lumpur, although there are variations between the two. The Klang Valley is geographically delineated by the Titiwangsa Mountains to the north and east and the Strait of Malacca to the west. It extends to Rawang in the northwest, Semenyih in the southeast, and Klang and Port Klang in the southwest. The conurbation is the heartland of Malaysia's industry and commerce. As of 2020, the Klang Valley is home to roughly 8 million people. Origin The valley is named after the Klang River, the principal river that flows through it that starts at Klang Gates Quartz Ridge in Gombak and flows into the Straits of Malacca in Port Klang, The river is closely linked to the early development of the area as a cluster ...

Electrical 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 ...

Rapid Transit
Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport generally found in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways (usually electric railway, electric) that operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles, and which is often grade-separated in tunnels or on elevated railways. Modern services on rapid transit systems are provided on designated lines between rapid transit station, stations typically using electric multiple units on rail tracks, although some systems use guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train a ...

Line 17 (São Paulo Metro)
Line 17 (Gold) ( pt, Linha 17–Ouro) is an under construction monorail project for the São Paulo Metro. The line will have 14 stations, beginning at the São Paulo-Morumbi station and ending at the Jabaquara station, with a branch to Congonhas station, connected to the São Paulo/Congonhas Airport. It will have integration with Line 1-Blue, Line 4-Yellow, and Line 5-Lilac as well as CPTM Line 9-Emerald. The line was originally one of the transportation projects supporting the 2014 FIFA World Cup. However, delays and contract disputes have pushed the completion date from the original 2013 full opening date to 2024. Once completed, the line will be the first in the system to have a branch. The line was originally envisioned to be long and will be opened in three stages. The first section will be long linking Congonhas-São Paulo Airport to São Judas Station, with an initial demand 18,000 passengers per day and construction starting in 2011. The second phase, expected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KL Monorail
The KL Monorail Line is one of the operational monorail systems in Malaysia. Operated as part of the RapidKL system by Rapid Rail, a subsidiary of Prasarana Malaysia, it is one of the components of the Klang Valley Integrated Transit System. The line is numbered and coloured on official transit maps. History This urban monorail line was opened on 31 August 2003, with 11 stations running on two parallel elevated tracks. It connects the KL Sentral transport hub in the south and Titiwangsa in the north with the "Golden Triangle", a commercial, shopping, and entertainment area consisting of the Bukit Bintang area, and surrounded by '' Jalan Imbi'', ''Jalan Bukit Bintang'', Jalan Sultan Ismail, and '' Jalan Raja Chulan''. The monorail scheme was announced by Kuala Lumpur City Hall in January 1990 after the Malaysian Government gave the go-ahead to the scheme at a cabinet meeting in June 1989. Its cost was then estimated at RM 143 million. The 14-km, 22-station system is designed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pphpd
Passengers per hour per direction (p/h/d), passengers per hour in peak direction (pphpd) or corridor capacity is a measure of the route capacity of a rapid transit or public transport system. Definition The corridor capacity in the passenger transport field refers to the maximum number of people which can be safely and comfortably transported per unit of time over a certain way with a defined width. The corridor capacity does not measure the number of vehicles which can be transported over such way, since the nuclear objective of passenger mobility is to transport passengers, not vehicles. In terms of quantities defined within the International System of Units, the corridor capacity may be measured in units of \mathrm^\cdot \mathrm^, ''i.e.'', the maximum number of passengers per second per meter of the corridor's width. An approximately equivalent concept in physics is volumetric flux. Directional flow Many public transport systems handle a high directional flow of pas ...

Mumbai Monorail
MMRDA Mumbai Monorail is an monorail system in the city of Mumbai, Maharashtra, India, built as part of a major expansion of public transport in the city. The project was implemented and is currently operated by the Mumbai Metropolitan Region Development Authority (MMRDA). It is the first monorail in India since the Kundala Valley Railway and Patiala State Monorail Trainways were closed in the 1920s. The system started commercial operation after partially opening its Phase 1 to the public in 2014. History Background The Mumbai Metropolitan Region Development Authority (MMRDA) first proposed a monorail in 2005. According to the MMRDA, the bus service operating in the city plied crowded and narrow areas at very slow speeds, thus offering no benefits to the commuters and adding to the traffic congestion. The MMRDA stated that the monorail would connect many parts of the city which were not connected by suburban rail system or the proposed metro rail system. The agency also stat ...

Welding
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal). In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that, based on weld configuration (butt, full penetration, fillet, etc.), can be stronger than the base material. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron beam, friction, and ultrasound. While often an i ...

Milling (machining)
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done by varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances. Milling can be done with a wide range of machine tools. The original class of machine tools for milling was the milling machine (often called a mill). After the advent of computer numerical control (CNC) in the 1960s, milling machines evolved into ''machining centers'': milling machines augmented by automatic tool changers, tool magazines or carousels, CNC capability, coolant systems, and enclosures. Milling centers are generally classified as vertical machining centers (VMCs) or horizontal machining centers (HMCs). The integrat ...

Lathe
A lathe () is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis. Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass-working. Lathes can be used to shape pottery, the best-known design being the Potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The workpiece is usually held in place by either one or two ''centers'', at least one of which can typically be moved horizontally to accommodate varying workpiece lengths. Other work-holding methods include clamping the work about the axis of rotation using a chuck or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
