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] |

Railway Air Brake
A railway air brake is a railway brake power braking system with compressed air as the operating medium. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. In various forms, it has been nearly universally adopted. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. Full air pressure causes each car to release the brakes. A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Overview Straight air brake In the air brake's simplest form, called the ''straight air system'', compressed air pushes on a piston in a cylinder. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train. Th ...

Electro-Motive Diesel
Progress Rail Locomotives, doing business as Electro-Motive Diesel (EMD), is an American manufacturer of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. The company is owned by Caterpillar through its subsidiary Progress Rail. Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, a designer and marketer of gasoline-electric self-propelled rail cars founded in 1922 and later renamed Electro-Motive Company (EMC). In 1930, General Motors purchased Electro-Motive Company and the Winton Engine Co., and in 1941 it expanded EMC's realm to locomotive engine manufacturing as Electro-Motive Division (EMD).

North British Locomotive Company
The North British Locomotive Company (NBL, NB Loco or North British) was created in 1903 through the merger of three Glasgow locomotive manufacturing companies; Sharp, Stewart and Company (Atlas Works), Neilson, Reid and Company (Hyde Park Works) and Dübs and Company (Queens Park Works), creating the largest locomotive manufacturing company in Europe and the British Empire. Its main factories were located at the neighbouring Atlas and Hyde Park Works in central Springburn, as well as the Queens Park Works in Polmadie. A new central Administration and Drawing Office for the combined company was completed across the road from the Hyde Park Works on Flemington Street by James Miller in 1909, later sold to Glasgow Corporation in 1961 to become the main campus of North Glasgow College (now Glasgow Kelvin College).

Vacuum Brake
The vacuum brake is a braking system employed on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal in British train equipment and in countries influenced by British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, primarily on narrow-gauge railroads. Their limitations caused them to be progressively superseded by compressed air systems starting in the United Kingdom from the 1970s onward. The vacuum brake system is now obsolete; it is not in large-scale usage anywhere in the world, other than in South Africa, largely supplanted by air brakes. Introduction In the earliest days of railways, trains were slowed or stopped by the application of manually applied brakes on the locomotive and in brake vehicles through the train, and later by steam power brakes on locomotives. This was clearly unsatisfactory, given the slow and unreliable response times (each brake being separately applied by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metre Gauge
Metre-gauge railways are narrow-gauge railways with track gauge of or 1 metre. The metre gauge is used in around of tracks around the world. It was used by European colonial powers, such as the French, British and German Empires. In Europe, large metre-gauge networks remain in use in Switzerland, Spain and many European towns with urban trams, but most metre-gauge local railways in France, Germany and Belgium closed down in the mid-20th century, although many still remain. With the revival of urban rail transport, metre-gauge light metros were established in some cities, and in other cities, metre gauge was replaced by standard gauge. The slightly-wider gauge is used in Sofia. Examples of metre-gauge See also * Italian metre gauge * Narrow-gauge railways A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

Vietnam Railways
Vietnam Railways (VNR, ) is the state-owned operator of the railway system in Vietnam. The principal route is the single-track North–South Railway line, running between Hanoi and Ho Chi Minh City. This was built at the metre gauge in the 1880s during the French colonial rule. There are also standard gauge lines running from Hanoi to the People’s Republic of China, eventually leading to Beijing, and some mixed gauge in and around Hanoi. Problems While the state of the country’s road network is consistently improving, the railway system makes a significant contribution to the national transport infrastructure, with multiple daily freight trains, many being movement of containers. The 29-34-hour passenger trip between Hanoi and Ho Chi Minh City is very popular both with locals and foreign visitors, accommodations are hard seat, soft seat, 4 beth sleeper and 6 beth sleeper. Coastal resorts such as Huế, Hội An, and Nha Trang lie along the route and gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
