95-459: Trains is a monthly magazine about trains and railroads aimed at railroad enthusiasts and railroad industry employees. The magazine primarily covers railroad happenings in the United States and Canada, but has some articles on railroading elsewhere. It was founded as Trains in 1940 by publisher Al C. Kalmbach and editorial director Linn Westcott. From October 1951 to March 1954,
190-500: A maglev train accident occurred in Lathen, killing 23 people. It was found to have been caused by human error in implementing safety checks. From 2006 no passengers were carried. At the end of 2011 the operation licence expired and was not renewed, and in early 2012 demolition permission was given for its facilities, including the track and factory. In March 2021 it was reported the CRRC
285-708: A third rail electric system , which is then used to power traction motors that drive the wheels. Electric traction offers a lower cost per mile of train operation but at a higher initial cost, which can only be justified on high traffic lines. Even though the cost per mile of construction is much higher, electric traction is cheaper to operate thanks to lower maintenance and purchase costs for locomotives and equipment. Compared to diesel locomotives, electric locomotives produce no direct emissions and accelerate much faster, making them better suited to passenger service, especially underground. Various other types of train propulsion have been tried, some more successful than others. In
380-612: A train driver controls the train's operation. They may also be installed on unpowered train cars known as cab or control cars , to allow for a train to operate with the locomotive at the rear. To prevent collisions or other accidents, trains are often scheduled, and almost always are under the control of train dispatchers . Historically, trains operated based on timetables ; most trains (including nearly all passenger trains), continue to operate based on fixed schedules, though freight trains may instead run on an as-needed basis, or when enough freight cars are available to justify running
475-868: A 110 kilometres per hour (68 mph) operating speed. Two more stages are planned of 9.7 kilometres (6 mi) and 37.4 kilometres (23.2 mi). Once completed it will become a circular line. It was shut down in September 2023. Transport System Bögl (TSB) is a driverless maglev system developed by the German construction company Max Bögl since 2010. Its primary intended use is for short to medium distances (up to 30 km) and speeds up to 150 km/h for uses such as airport shuttles . The company has been doing test runs on an 820-meter-long test track at their headquarters in Sengenthal , Upper Palatinate , Germany , since 2012 clocking over 100,000 tests covering
570-541: A 30 percent increase in traction efficiency and a 60 percent increase in speed over the stock in use on the line since. The vehicles entered service in July 2021 with a top speed of 140 km/h (87 mph). CRRC Zhuzhou Locomotive said in April 2020 it is developing a model capable of 200 km/h (120 mph). There are two competing efforts for high-speed maglev systems, i.e., 300–620 km/h (190–390 mph). In
665-502: A 60-metre ramp which was later extended to 980 metres. From the late 1970s to the 1980s five prototypes of cars were built that received designations from TP-01 (ТП-01) to TP-05 (ТП-05). The early cars were supposed to reach the speed up to 100 kilometres per hour (62 mph). The construction of a maglev track using the technology from Ramenskoye started in Armenian SSR in 1987 and was planned to be completed in 1991. The track
760-471: A 90-foot test track in Johnson's basement "absolutely noiseless[ly] and without the least vibration." A series of German patents for magnetic levitation trains propelled by linear motors were awarded to Hermann Kemper between 1937 and 1941. An early maglev train was described in U.S. patent 3,158,765 , "Magnetic system of transportation", by G. R. Polgreen on 25 August 1959. The first use of "maglev" in
855-640: A 908 metres (2,979 ft) track was opened in Hamburg for the first International Transportation Exhibition (IVA 79). Interest was sufficient that operations were extended three months after the exhibition finished, having carried more than 50,000 passengers. It was reassembled in Kassel in 1980. In 1979 the USSR town of Ramenskoye ( Moscow oblast ) built an experimental test site for running experiments with cars on magnetic suspension. The test site consisted of
950-473: A German maglev company, had a test track in Emsland with a total length of 31.5 kilometres (19.6 mi). The single-track line ran between Dörpen and Lathen with turning loops at each end. The trains regularly ran at up to 420 kilometres per hour (260 mph). Paying passengers were carried as part of the testing process. The construction of the test facility began in 1980 and finished in 1984. In 2006,
1045-472: A United States patent was in "Magnetic levitation guidance system" by Canadian Patents and Development Limited . In 1912 French-American inventor Émile Bachelet demonstrated a model train with electromagnetic levitation and propulsion in Mount Vernon, New York. Bachelet's first related patent, U.S. patent 1,020,942 was granted in 1912. The electromagnetic propulsion was by attraction of iron in

#17327983369811140-582: A concern at low speeds, and is one of the reasons why JR abandoned a purely repulsive system and adopted the sidewall levitation system. At higher speeds other modes of drag dominate. The drag force can be used to the electrodynamic system's advantage, however, as it creates a varying force in the rails that can be used as a reactionary system to drive the train, without the need for a separate reaction plate, as in most linear motor systems. Laithwaite led development of such "traverse-flux" systems at his Imperial College laboratory. Alternatively, propulsion coils on
1235-589: A distance of over 65,000 km as of 2018. In 2018 Max Bögl signed a joint venture with the Chinese company Chengdu Xinzhu Road & Bridge Machinery Co. with the Chinese partner given exclusive rights of production and marketing for the system in China. The joint venture constructed a 3.5 km (2.2 mi) demonstration line near Chengdu , China, and two vehicles were airlifted there in June, 2020. In February 2021
1330-463: A driver directly present. Around the world, various track gauges are in use for trains. In most cases, trains can only operate on tracks that are of the same gauge; where different gauge trains meet, it is known as a break of gauge . Standard gauge , defined as 1,435 mm (4 ft 8.5 in) between the rails, is the most common gauge worldwide, though both broad-gauge and narrow-gauge trains are also in use. Trains also need to fit within
1425-516: A few holdouts in Europe and South America. China was the last country to fully dieselize, due to its abundant coal reserves; steam locomotives were used to haul mainline trains as late as 2005 in Inner Mongolia . Trains began to face strong competition from automobiles and freight trucks in the 1930s, which greatly intensified following World War II. After the war, air transport also became
1520-564: A fixed schedule and have priority over freight trains . Passenger trains can be divided into short and long distance services. Long distance passenger trains travel over hundreds or even thousands of miles between cities. The longest passenger train service in the world is Russia's Trans-Siberian Railway between Moscow and Vladivostok , a distance of 9,289 kilometers (5,772 mi). In general, long distance trains may take days to complete their journeys, and stop at dozens of stations along their routes. For many rural communities, they are
1615-612: A high-speed maglev system. Instead, overcoming drag takes the most energy. Vactrain technology has been proposed as a means to overcome this limitation. Despite over a century of research and development, there are only six operational maglev trains today — three in China, two in South Korea, and one in Japan. In the late 1940s, the British electrical engineer Eric Laithwaite , a professor at Imperial College London , developed
1710-491: A locomotive) is referred to as a rake . A collection of rail vehicles may also be called a consist. A set of vehicles that are coupled together (such as the Pioneer Zephyr ) is called a trainset. The term rolling stock is used to describe any kind of railway vehicle. Trains are an evolution of wheeled wagons running on stone wagonways , the earliest of which were built by Babylon circa 2,200 BCE. Starting in
1805-598: A means of fighting traffic congestion on highways in urban areas. Bogies, also known in North America as trucks, support the wheels and axles of trains. Trucks range from just one axle to as many as four or more. Two-axle trucks are in the widest use worldwide, as they are better able to handle curves and support heavy loads than single axle trucks. Train vehicles are linked to one another by various systems of coupling. In much of Europe, India, and South America, trains primarily use buffers and chain couplers . In
1900-615: A mile of stopping distance. As such, emphasis is on educating motorists to yield to trains at crossings and avoid trespassing. The first trains were rope-hauled, gravity powered or pulled by horses. Steam locomotives work by burning coal, wood or oil fuel in a boiler to heat water into steam, which powers the locomotive's pistons which are in turn connected to the wheels. In the mid 20th century, most steam locomotives were replaced by diesel or electric locomotives, which were cheaper, cleaner, and more reliable. Steam locomotives are still used in heritage railways operated in many countries for
1995-599: A new high-speed maglev line, the Chuo Shinkansen , started in 2014. It is being built by extending the SCMaglev test track in Yamanashi in both directions. The completion date is unknown, with the estimate of 2027 no longer possible following a local governmental rejection of a construction permit. Transrapid 05 was the first maglev train with longstator propulsion licensed for passenger transportation. In 1979,

#17327983369812090-400: A significant competitor for passenger trains. Large amounts of traffic shifted to these new forms of transportation, resulting in a widespread decline in train service, both freight and passenger. A new development in the 1960s was high-speed rail , which runs on dedicated rights of way and travels at speeds of 240 kilometers per hour (150 mph) or greater. The first high-speed rail service
2185-551: A single car along a short section of track at the fairgrounds. It was removed after the fair. It was shown at the Aoi Expo in 1987 and is now on static display at Okazaki Minami Park. In 1993, South Korea completed the development of its own maglev train, shown off at the Taejŏn Expo '93 , which was developed further into a full-fledged maglev capable of travelling up to 110 kilometres per hour (68 mph) in 2006. This final model
2280-874: A single rail, while funiculars and rack railways are uniquely designed to traverse steep slopes. Experimental trains such as high speed maglevs , which use magnetic levitation to float above a guideway, are under development in the 2020s and offer higher speeds than even the fastest conventional trains. Trains which use alternative fuels such as natural gas and hydrogen are another 21st-century development. Trains can be sorted into types based on whether they haul passengers or freight (though mixed trains which haul both exist), by their weight ( heavy rail for regular trains, light rail for lighter transit systems), by their speed, by their distance (short haul, long distance , transcontinental ), and by what form of track they use. Conventional trains operate on two rails, but several other types of track systems are also in use around
2375-750: A small proportion of the train systems in use worldwide. Almost all monorail trains use linear induction motors Maglev Maglev (derived from magnetic levitation ) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance . Compared to conventional railways, maglev trains can have higher top speeds, superior acceleration and deceleration, lower maintenance costs, improved gradient handling, and lower noise. However, they are more expensive to build, cannot use existing infrastructure, and use more energy at high speeds. Maglev trains have set several speed records . The train speed record of 603 km/h (375 mph)
2470-595: A train. Simple repairs may be done while a train is parked on the tracks, but more extensive repairs will be done at a motive power depot . Similar facilities exist for repairing damaged or defective train cars. Maintenance of way trains are used to build and repair railroad tracks and other equipment. Train drivers , also known as engineers, are responsible for operating trains. Conductors are in charge of trains and their cargo, and help passengers on passenger trains. Brakeman , also known as trainmen, were historically responsible for manually applying brakes, though
2565-557: A transfer to the Seoul Metropolitan Subway at AREX 's Incheon International Airport Station and is offered free of charge to anyone to ride, operating between 9 am and 6 pm with 15-minute intervals. The maglev system was co-developed by the South Korea Institute of Machinery and Materials (KIMM) and Hyundai Rotem . It is 6.1 kilometres (3.8 mi) long, with six stations and
2660-432: A variety of systems, which may include characteristics of trams, heavier passenger trains, and rapid transit systems. There are a number of specialized trains which differ from the traditional definition of a train as a set of vehicles which travels on two rails. Monorails were developed to meet medium-demand traffic in urban transit, and consist of a train running on a single rail, typically elevated. Monorails represent
2755-504: A vehicle on the Chinese test track hit a top speed of 169 km/h (105 mph). According to the International Maglev Board there are at least four maglev research programmes underway in China at: Southwest Jiaotong University (Chengdu), Tongji University (Shanghai), CRRC Tangshan-Changchun Railway Vehicle Co. , and Chengdu Aircraft Industry Group . The latest high-speed prototype , unveiled in July 2021,
2850-563: A wide variety of cargo, flatcars (also known as flat wagons ) which have flat tops to hold cargo, hopper cars which carry bulk commodities, and tank cars which carry liquids and gases. Examples of more specialized types of train cars include bottle cars which hold molten steel, Schnabel cars which handle very heavy loads, and refrigerator cars which carry perishable goods. Early train cars were small and light, much like early locomotives, but over time they have become larger as locomotives have become more powerful. A passenger train
2945-804: Is HSST (and its descendant, the Linimo line) by Japan Airlines and the other, which is more well known, is SCMaglev by the Central Japan Railway Company . The development of the latter started in 1969. The first successful SCMaglev run was made on a short track at the Japanese National Railways ' (JNR's) Railway Technical Research Institute in 1972. Maglev trains on the Miyazaki test track (a later, 7 km long test track) regularly hit 517 kilometres per hour (321 mph) by 1979. After an accident destroyed

3040-481: Is a series of connected vehicles that run along a railway track and transport people or freight . Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars . Passengers and cargo are carried in railroad cars , also known as wagons or carriages. Trains are designed to a certain gauge , or distance between rails. Most trains operate on steel tracks with steel wheels,

Several favourable conditions existed when the link was built: After the system closed in 1995, the original guideway lay dormant until 2003, when a replacement cable-hauled system, the AirRail Link Cable Liner people mover, was opened. Transrapid,
3230-535: Is produced either by superconducting magnets (as in JR–Maglev) or by an array of permanent magnets (as in Inductrack ). The repulsive and attractive force in the track is created by an induced magnetic field in wires or other conducting strips in the track. A major advantage of EDS maglev systems is that they are dynamically stable—changes in distance between the track and the magnets creates strong forces to return
3325-465: Is typically arranged on a series of C-shaped arms, with the upper portion of the arm attached to the vehicle, and the lower inside edge containing the magnets. The rail is situated inside the C, between the upper and lower edges. Magnetic attraction varies inversely with the square of distance, so minor changes in distance between the magnets and the rail produce greatly varying forces. These changes in force are dynamically unstable—a slight divergence from
3420-414: Is typically the case with electrodynamic suspension maglev trains. Aerodynamic factors may also play a role in the levitation of such trains. The two main types of maglev technology are: In electromagnetic suspension (EMS) systems, the train levitates by attraction to a ferromagnetic (usually steel) rail while electromagnets , attached to the train, are oriented toward the rail from below. The system
3515-428: Is used to transport people along a railroad line. These trains may consist of unpowered passenger railroad cars (also known as coaches or carriages) hauled by one or more locomotives, or may be self-propelled; self propelled passenger trains are known as multiple units or railcars . Passenger trains travel between stations or depots , where passengers may board and disembark. In most cases, passenger trains operate on
3610-664: The British Rail Research Division in Derby , along with teams at several civil engineering firms, the "transverse-flux" system was developed into a working system. The first commercial maglev people mover was simply called " MAGLEV " and officially opened in 1984 near Birmingham , England. It operated on an elevated 600 metres (2,000 ft) section of monorail track between Birmingham Airport and Birmingham International railway station , running at speeds up to 42 kilometres per hour (26 mph). The system

France, Russia, Switzerland, and Japan were leaders in adopting widespread electrified railroads, while other nations focused primarily on dieselization . By 1980, the majority of the world's steam locomotives had been retired, though they continued to be used in parts of Africa and Asia, along with
3800-507: The Stockton and Darlington Railway in 1825. British engineer George Stephenson ran a steam locomotive named Locomotion No. 1 on this 40-kilometer (25-mile) long line, hauling over 400 passengers at up to 13 kilometers per hour (8 mph). The success of this locomotive, and Stephenson's Rocket in 1829, convinced many of the value in steam locomotives, and within a decade the stock market bubble known as " Railway Mania " started across
3895-565: The Throgs Neck Bridge , James Powell , a researcher at Brookhaven National Laboratory (BNL), thought of using magnetically levitated transportation. Powell and BNL colleague Gordon Danby worked out a maglev concept using static magnets mounted on a moving vehicle to induce electrodynamic lifting and stabilizing forces in specially shaped loops, such as figure-of-8 coils on a guideway. These were patented in 1968–1969. Japan operates two independently developed maglev trains. One

In the early 1970s, Laithwaite discovered a new arrangement of magnets, the magnetic river , that allowed a single linear motor to produce both lift and forward thrust, allowing a maglev system to be built with a single set of magnets. Working at

Train accidents sometimes occur, including derailments (when a train leaves the tracks) and train wrecks (collisions between trains). Accidents were more common in the early days of trains, when railway signal systems, centralized traffic control , and failsafe systems to prevent collisions were primitive or did not yet exist. To prevent accidents, systems such as automatic train stop are used; these are failsafe systems that apply
4180-405: The 1500s, wagonways were introduced to haul material from mines; from the 1790s, stronger iron rails were introduced. Following early developments in the second half of the 1700s, in 1804 a steam locomotive built by British inventor Richard Trevithick powered the first ever steam train. Outside of coal mines, where fuel was readily available, steam locomotives remained untried until the opening of
4275-502: The 1970s as an alternative to congested highways and a means to promote development , as has light rail in the 21st century. Freight trains remain important for the transport of bulk commodities such as coal and grain, as well as being a means of reducing road traffic congestion by freight trucks. While conventional trains operate on relatively flat tracks with two rails, a number of specialized trains exist which are significantly different in their mode of operation. Monorails operate on
4370-483: The United Kingdom. News of the success of steam locomotives quickly reached the United States, where the first steam railroad opened in 1829. American railroad pioneers soon started manufacturing their own locomotives, designed to handle the sharper curves and rougher track typical of the country's railroads. The other nations of Europe also took note of British railroad developments, and most countries on
4465-790: The United States, the Gatimaan Express in India, and the KTM ETS in Malaysia. A number of types of trains are used to provide rapid transit to urban areas. These are distinct from traditional passenger trains in that they operate more frequently, typically do not share tracks with freight trains, and cover relatively short distances. Many different kinds of systems are in use globally. Rapid transit trains that operate in tunnels below ground are known as subways, undergrounds, or metros. Elevated railways operate on viaducts or bridges above
4560-578: The benefits of trains for transport led to a revival in their use and importance. Freight trains are significantly more efficient than trucks, while also emitting far fewer greenhouse gas emissions per ton-mile; passenger trains are also far more energy efficient than other modes of transport. According to the International Energy Agency , "On average, rail requires 12 times less energy and emits 7–11 times less GHGs per passenger-km travelled than private vehicles and airplanes, making it

More advanced safety systems, such as positive train control , can also automatically regulate train speed, preventing derailments from entering curves or switches too fast. Modern trains have a very good safety record overall, comparable with air travel. In the United States between 2000 and 2009, train travel averaged 0.43 deaths per billion passenger miles traveled. While this
4750-694: The cars and apply the brakes when the train went downhill. Hand brakes are still used to park cars and locomotives, but the predominant braking system for trains globally is air brakes, invented in 1869 by George Westinghouse . Air brakes are applied at once to the entire train using air hoses. For safety and communication, trains are equipped with bells , horns , and lights . Steam locomotives typically use steam whistles rather than horns. Other types of lights may be installed on locomotives and cars, such as classification lights , Mars Lights , and ditch lights . Locomotives are in most cases equipped with cabs, also known as driving compartments, where
4845-473: The closure of many rapid transit and tram systems during this time as well. Since the 1970s, governments, environmentalists , and train advocates have promoted increased use of trains due to their greater fuel efficiency and lower greenhouse gas emissions compared to other modes of land transport. High-speed rail , first built in the 1960s, has proven competitive with cars and planes over short to medium distances. Commuter rail has grown in importance since

#17327983369814940-465: The continent constructed and opened their first railroads in the 1830s and 1840s, following the first run of a steam train in France in late 1829. In the 1850s, trains continued to expand across Europe, with many influenced by or purchases of American locomotive designs. Other European countries pursued their own distinct designs. Around the world, steam locomotives grew larger and more powerful throughout
5035-414: The distance of 30.5 kilometres (19 mi) in just over 8 minutes. Different maglev systems achieve levitation in different ways, which broadly fall into two categories: electromagnetic suspension (EMS) and electrodynamic suspension (EDS) . Propulsion is typically provided by a linear motor . The power needed for levitation is typically not a large percentage of the overall energy consumption of
5130-457: The downside, the dynamic instability demands fine track tolerances, which can offset this advantage. Eric Laithwaite was concerned that to meet required tolerances, the gap between magnets and rail would have to be increased to the point where the magnets would be unreasonably large. In practice, this problem was addressed through improved feedback systems, which support the required tolerances. Air gap and energy efficiency can be improved by using
5225-537: The field exerted by magnets on the train and the applied field creates a force moving the train forward. The term "maglev" refers not only to the vehicles, but to the railway system as well, specifically designed for magnetic levitation and propulsion. All operational implementations of maglev technology make minimal use of wheeled train technology and are not compatible with conventional rail tracks . Because they cannot share existing infrastructure, maglev systems must be designed as standalone systems. The SPM maglev system
5320-412: The first decade of the 1900s. Experimentation with diesel and gas power continued, culminating in the German " Flying Hamburger " in 1933, and the influential American EMD FT in 1939. These successful diesel locomotives showed that diesel power was superior to steam, due to lower costs, ease of maintenance, and better reliability. Meanwhile, Italy developed an extensive network of electric trains during

World War II brought great destruction to existing railroads across Europe, Asia, and Africa. Following the war's conclusion in 1945, nations which had suffered extensive damage to their railroad networks took the opportunity provided by Marshall Plan funds (or economic assistance from the USSR and Comecon , for nations behind
5510-425: The first full-size working model of the linear induction motor . He became professor of heavy electrical engineering at Imperial College in 1964, where he continued his successful development of the linear motor. Since linear motors do not require physical contact between the vehicle and guideway, they became a common fixture on advanced transportation systems in the 1960s and 1970s. Laithwaite joined one such project,
5605-731: The first train powered by electricity in 1879, and went on to pioneer electric trams . Another German inventor, Rudolf Diesel , constructed the first diesel engine in the 1890s, though the potential of his invention to power trains was not realized until decades later. Between 1897 and 1903, tests of experimental electric locomotives on the Royal Prussian Military Railway in Germany demonstrated they were viable, setting speed records in excess of 160 kilometers per hour (100 mph). Early gas powered " doodlebug " self-propelled railcars entered service on railroads in
5700-410: The ground, often on top of city streets. "Metro" may also refer to rapid transit that operates at ground level. In many systems, two or even all three of these types may exist on different portions of a network. Trams, also known in North America as streetcars, typically operate on or parallel to streets in cities, with frequent stops and a high frequency of service. Light rail is a catchall term for
5795-462: The guideway and the train exert a magnetic field, and the train is levitated by the repulsive and attractive force between these magnetic fields. In some configurations, the train can be levitated only by repulsive force. In the early stages of maglev development at the Miyazaki test track, a purely repulsive system was used instead of the later repulsive and attractive EDS system. The magnetic field

#17327983369815890-418: The guideway are used to exert a force on the magnets in the train and make the train move forward. The propulsion coils that exert a force on the train are effectively a linear motor: an alternating current through the coils generates a continuously varying magnetic field that moves forward along the track. The frequency of the alternating current is synchronized to match the speed of the train. The offset between

Beginning in the 1920s, and accelerating following World War II , diesel and electric locomotives replaced steam as the means of motive power. Following the development of cars , trucks , and extensive networks of highways which offered greater mobility, as well as faster airplanes , trains declined in importance and market share, and many rail lines were abandoned. The spread of buses led to
6080-480: The leisure and enthusiast market. Diesel locomotives are powered with a diesel engine, which generates electricity to drive traction motors. This is known as a diesel–electric transmission , and is used on most larger diesels. Diesel power replaced steam for a variety of reasons: diesel locomotives were less complex, far more reliable, cheaper, cleaner, easier to maintain, and more fuel efficient. Electric trains receive their current via overhead lines or through
6175-467: The low friction of which makes them more efficient than other forms of transport. Trains have their roots in wagonways , which used railway tracks and were powered by horses or pulled by cables . Following the invention of the steam locomotive in the United Kingdom in 1802, trains rapidly spread around the world, allowing freight and passengers to move over land faster and cheaper than ever possible before. Rapid transit and trams were first built in
6270-660: The magazine was named Trains and Travel . Jim Wrinn, a former reporter and editor at the Charlotte Observer , served as editor from 2004 until his death in 2022. Carl A. Swanson succeeded him. Trains was long among the 11 magazines published by Kalmbach Media , based in Waukesha, Wisconsin . In May 2024, Kalmbach Media sold Trains , along with other railroad and astronomy-related publications to Firecrown Media. Train A train (from Old French trahiner , from Latin trahere , "to pull, to draw" )
6365-613: The maglev theme was continued by the Engineering Research Center "TEMP" (ИНЦ "ТЭМП") this time by the order from the Moscow government . The project was named V250 (В250). The idea was to build a high-speed maglev train to connect Moscow to the Sheremetyevo airport . The train would consist of 64-seater cars and run at speeds up to 250 kilometres per hour (160 mph). In 1993, due to the financial crisis ,
6460-715: The mid 1900s, gas turbine locomotives were developed and successfully used, though most were retired due to high fuel costs and poor reliability. In the 21st century, alternative fuels for locomotives are under development, due to increasing costs for diesel and a desire to reduce greenhouse gas emissions from trains. Examples include hydrail (trains powered by hydrogen fuel cells) and the use of compressed or liquefied natural gas . Train cars, also known as wagons, are unpowered rail vehicles which are typically pulled by locomotives. Many different types exist, specialized to handle various types of cargo. Some common types include boxcars (also known as covered goods wagons ) that carry
6555-502: The most efficient mode of motorised passenger transport. Aside from shipping, freight rail is the most energy-efficient and least carbon-intensive way to transport goods." As such, rail transport is considered an important part of achieving sustainable energy . Intermodal freight trains, carrying double-stack shipping containers , have since the 1970s generated significant business for railroads and gained market share from trucks. Increased use of commuter rail has also been promoted as
6650-533: The only form of public transportation available. Short distance or regional passenger trains have travel times measured in hours or even minutes, as opposed to days. They run more frequently than long distance trains, and are often used by commuters. Short distance passenger trains specifically designed for commuters are known as commuter rail . High speed trains are designed to be much faster than conventional trains, and typically run on their own separate tracks than other, slower trains. The first high speed train
6745-472: The optimum position tends to grow, requiring sophisticated feedback systems to maintain a constant distance from the track, (approximately 15 millimetres [0.59 in]). The major advantage to suspended maglev systems is that they work at all speeds, unlike electrodynamic systems, which only work at a minimum speed of about 30 kilometres per hour (19 mph). This eliminates the need for a separate low-speed suspension system, and can simplify track layout. On
6840-501: The project was abandoned. However, from 1999 the "TEMP" research center had been participating as a co-developer in the creation of the linear motors for the Moscow Monorail system. The world's first commercial maglev system was a low-speed maglev shuttle that ran between the airport terminal of Birmingham International Airport and the nearby Birmingham International railway station between 1984 and 1995. Its track length
6935-830: The public imagination, "maglev" often evokes the concept of an elevated monorail track with a linear motor . Maglev systems may be monorail or dual rail—the SCMaglev MLX01 for instance uses a trench-like track—and not all monorail trains are maglevs. Some railway transport systems incorporate linear motors but use electromagnetism only for propulsion , without levitating the vehicle. Such trains have wheels and are not maglevs. Maglev tracks, monorail or not, can also be constructed at grade or underground in tunnels. Conversely, non-maglev tracks, monorail or not, can be elevated or underground too. Some maglev trains do incorporate wheels and function like linear motor-propelled wheeled vehicles at slower speeds but levitate at higher speeds. This
7030-489: The registration of Bachelet Levitated Railway Syndicate Limited July 9 in London, just weeks before the start of WWI. Bachelet's second related patent, U.S. patent 1,020,943 granted the same day as the first, had the levitation electromagnets in the train and the track was aluminum plate. In the patent he stated that this was a much cheaper construction, but he did not demonstrate it. In 1959, while delayed in traffic on
7125-724: The rest of the century as technology advanced. Trains first entered service in South America, Africa, and Asia through construction by imperial powers , which starting in the 1840s built railroads to solidify control of their colonies and transport cargo for export. In Japan, which was never colonized, railroads first arrived in the early 1870s. By 1900, railroads were operating on every continent besides uninhabited Antarctica. Even as steam locomotive technology continued to improve, inventors in Germany started work on alternative methods for powering trains. Werner von Siemens built
7220-547: The rest of the world, Janney couplers are the most popular, with a few local variations persisting (such as Wilson couplers in the former Soviet Union). On multiple units all over the world, Scharfenberg couplers are common. Because trains are heavy, powerful brakes are needed to slow or stop trains, and because steel wheels on steel rails have relatively low friction, brakes must be distributed among as many wheels as possible. Early trains could only be stopped by manually applied hand brakes, requiring workers to ride on top of
7315-458: The socalled "Hybrid Electromagnetic Suspension (H-EMS)", where the main levitation force is generated by permanent magnets, while the electromagnet controls the air gap, what is called electropermanent magnets . Ideally it would take negligible power to stabilize the suspension and in practice the power requirement is less than it would be if the entire suspension force were provided by electromagnets alone. In electrodynamic suspension (EDS), both
7410-406: The system to its original position. In addition, the attractive force varies in the opposite manner, providing the same adjustment effects. No active feedback control is needed. However, at slow speeds, the current induced in these coils and the resultant magnetic flux is not large enough to levitate the train. For this reason, the train must have wheels or some other form of landing gear to support
7505-763: The term is used today to refer to crew members who perform tasks such as operating switches, coupling and uncoupling train cars, and setting handbrakes on equipment. Steam locomotives require a fireman who is responsible for fueling and regulating the locomotive's fire and boiler. On passenger trains, other crew members assist passengers, such as chefs to prepare food, and service attendants to provide food and drinks to passengers. Other passenger train specific duties include passenger car attendants, who assist passengers with boarding and alighting from trains, answer questions, and keep train cars clean, and sleeping car attendants, who perform similar duties in sleeping cars . Some trains can operate with automatic train operation without
7600-494: The train by direct current solenoids spaced along the track. The electromagnetic levitation was due to repulsion of the aluminum base plate of the train by the pulsating current electromagnets under the track. The pulses were generated by Bachelet's own Synchronizing-interrupter U.S. patent 986,039 supplied with 220 VAC. As the train moved it switched power to the section of track that it was on. Bachelet went on to demonstrate his model in London, England in 1914, which resulted in
7695-456: The train until it reaches take-off speed. Since a train may stop at any location, due to equipment problems for instance, the entire track must be able to support both low- and high-speed operation. Another downside is that the EDS system naturally creates a field in the track in front and to the rear of the lift magnets, which acts against the magnets and creates magnetic drag. This is generally only
7790-489: The train, a new design was selected. In Okazaki , Japan (1987), the SCMaglev was used for test rides at the Okazaki exhibition. Tests in Miyazaki continued throughout the 1980s, before transferring to a far longer test track, 20 kilometres (12 mi) long, in Yamanashi in 1997. The track has since been extended to almost 43 kilometres (27 mi). The 603 kilometres per hour (375 mph) world speed record for crewed trains
7885-540: The world, such as monorail . The railway terminology that is used to describe a train varies between countries. The International Union of Railways seeks to provide standardised terminology across languages. The Association of American Railroads provides terminology for North America. The British Rail Safety and Standards Board defines a train as a "light locomotive, self-propelled rail vehicle or road-rail vehicle in rail mode." A collection of passenger or freight carriages connected together (not necessarily with
7980-411: Was 600 metres (2,000 ft), and trains levitated at an altitude of 15 millimetres [0.59 in], levitated by electromagnets, and propelled with linear induction motors. It operated for 11 years and was initially very popular with passengers, but obsolescence problems with the electronic systems made it progressively unreliable as years passed, leading to its closure in 1995. One of the original cars
8075-404: Was awarded U.S. patent 782,312 (14 February 1905) and U.S. patent RE12700 (21 August 1907). In 1907, another early electromagnetic transportation system was developed by F. S. Smith. In 1908, Cleveland mayor Tom L. Johnson filed a patent for a wheel-less "high-speed railway" levitated by an induced magnetic field. Jokingly known as "Greased Lightning," the suspended car operated on
8170-481: Was closed in 1995 due to reliability problems. High-speed transportation patents were granted to various inventors throughout the world. The first relevant patent, U.S. patent 714,851 (2 December 1902), issued to Albert C. Albertson, used magnetic levitation to take part of the weight off of the wheels while using conventional propulsion. Early United States patents for a linear motor propelled train were awarded to German inventor Alfred Zehden . The inventor
8265-874: Was higher than that of air travel at 0.07 deaths per billion passenger miles, it was also far below the 7.28 deaths per billion passenger miles of car travel. In the 21st century, several derailments of oil trains caused fatalities, most notably the Canadian Lac-Mégantic rail disaster in 2013 which killed 47 people and leveled much of the town of Lac-Mégantic . The vast majority of train-related fatalities, over 90 percent, are due to trespassing on railroad tracks, or collisions with road vehicles at level crossings . Organizations such as Operation Lifesaver have been formed to improve safety awareness at railroad crossings, and governments have also launched ad campaigns. Trains cannot stop quickly when at speed; even an emergency brake application may still require more than
8360-590: Was incorporated in the Incheon Airport Maglev which opened on 3 February 2016, making South Korea the world's fourth country to operate its own self-developed maglev after the United Kingdom's Birmingham International Airport, Germany's Berlin M-Bahn , and Japan 's Linimo . It links Incheon International Airport to the Yongyu Station and Leisure Complex on Yeongjong island . It offers
8455-511: Was investigating reviving the Emsland test track. In May 2019 CRRC had unveiled its "CRRC 600" prototype which is designed to reach 600 kilometres per hour (370 mph). In Vancouver, Canada, the HSST-03 by HSST Development Corporation ( Japan Airlines and Sumitomo Corporation ) was exhibited at Expo 86 , and ran on a 400-metre (0.25 mi) test track that provided guests with a ride in
8550-672: Was manufactured by CRRC Qingdao Sifang . Development of the low-to-medium speed systems, that is, 100–200 km/h (62–124 mph), by the CRRC has led to opening lines such as the Changsha Maglev Express in 2016 and the Line S1 in Beijing in 2017. In April 2020 a new model capable of 160 km/h (99 mph) and compatible with the Changsha line completed testing. The vehicle, under development since 2018, has
8645-487: Was set by the experimental Japanese L0 Series maglev in 2015. From 2002 until 2021, the record for the highest operational speed of a passenger train of 431 kilometres per hour (268 mph) was held by the Shanghai maglev train , which uses German Transrapid technology. The service connects Shanghai Pudong International Airport and the outskirts of central Pudong , Shanghai . At its historical top speed, it covered
8740-661: Was set there in 2015. Development of HSST started in 1974. In Tsukuba , Japan (1985), the HSST-03 ( Linimo ) became popular at the Tsukuba World Exposition , in spite of its low 30 kilometres per hour (19 mph) top speed. In Saitama , Japan (1988), the HSST-04-1 was revealed at the Saitama exhibition in Kumagaya . Its fastest recorded speed was 300 kilometres per hour (190 mph). Construction of
8835-542: Was supposed to connect the cities of Yerevan and Sevan via the city of Abovyan . The original design speed was 250 kilometres per hour (160 mph) which was later lowered to 180 kilometres per hour (110 mph). However, the Spitak earthquake in 1988 and the First Nagorno-Karabakh War caused the project to freeze. In the end the overpass was only partially constructed. In the early 1990s,
8930-558: Was the Japanese Shinkansen , which entered service in 1964. In the following decades, high speed rail networks were developed across much of Europe and Eastern Asia, providing fast and reliable service competitive with automobiles and airplanes. The first high-speed train in the Americas was Amtrak 's Acela in the United States, which entered service in 2000. Towards the end of the 20th century, increased awareness of
9025-552: Was the Japanese Shinkansen , which opened in 1964. In the 21st century, services such as the French TGV and German Intercity Express are competitive with airplanes in travel time over short to medium distances. A subset of high speed trains are higher speed trains , which bridge the gap between conventional and high speed trains, and travel at speeds between the two. Examples include the Northeast Regional in
