Query: Do mag lev trains exist?
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 was , and trains levitated at an altitude of , 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 is now on display at Railworld in Peterborough, together with the RTV31 hover train vehicle. Another is on display at the National Railway Museum in York.
, Switzerland has no high-speed trains of its own yet. French TGV (TGV Lyria) and German ICE lines extend into Switzerland, but given the dense rail traffic, short distances between Swiss cities (because of the country's small size) and the often difficult terrain, they do not attain speeds higher than 200 km/h (ICE3) or 160 km/h (TGV, ICE1, ICE2). The fastest Swiss trains are the ICN tilting trains, operated by the Swiss Federal Railways since May 2000. They can reach higher speeds than conventional trains on the curve-intensive Swiss network, however the top speed of 200 km/h can only be reached on high-speed lines. The former Cisalpino consortium owned by the Swiss Federal Railways and Trenitalia used Pendolino tilting trains on two of its international lines. These trains are now operated by the Swiss Federal Railways and Trenitalia.
In 2016 the CEO, Dirk Ahlborn, announced an agreement with the Slovakian government to perform feasibility studies regarding routes connecting Vienna, Austria to Bratislava, Slovakia, and Bratislava to Budapest, Hungary. Total costs for this project are estimated to be . The resulting annual system capacity is projected to be 10 million passengers. HTT announced in March 2016 that they would be using passive Inductrack systems for their titular Hyperloop. In 2018, however, the agreement expired.
High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of and existing lines in excess of are widely considered to be high-speed, with some extending the definition to include lower speeds in areas for which these speeds still represent significant improvements. The first such system began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design.
Since their introduction, Japan's Shinkansen systems have been undergoing constant improvement, not only increasing line speeds. Over a dozen train models have been produced, addressing diverse issues such as tunnel boom noise, vibration, aerodynamic drag, lines with lower patronage ("Mini shinkansen"), earthquake and typhoon safety, braking distance, problems due to snow, and energy consumption (newer trains are twice as energy efficient as the initial ones despite greater speeds).
GateKeeper operates with three open-air steel and fiberglass trains, each with eight cars of four seats each, with two on each side of the track. Each train holds 32 riders and the ride has a capacity of about 1,710 riders per hour. Riders are restrained by flexible over-the-shoulder restraints and interlocking seat belts and riders are required to be between and to ride. Because the seats are on the side of the track, a cantilevered steel arm is used to support the wings. The trains are painted Sunset Gold with Zenith, Meteor, and Orion Gold accents. The fourth row of each train has extendable harnesses enabling large passengers to ride. The front of each train is shaped to resemble the head of a griffin. The griffin's eyes and the outside seats of each row incorporate LED lighting, a first for a roller coaster at Cedar Point. The LED lights on the trains recharge while the trains are in the station. Unlike the other B&M coasters at Cedar Point, the station's floor does not drop before the trains dispatch, as guests are required to climb into the seats while boarding.
For its first use in combat, during the 1862 Peninsula Campaign, the Rogers train substituted a new telegraph instrument, the Beardslee Patent Magneto-Electric Field Telegraph Machine, invented by George W. Beardslee of New York. This instrument required no battery, using instead a hand-cranked generator, but it was also based on a dial indicator. The Beardslee telegraph was housed in a wooden chest with handles and weighed about 100 pounds. It had two significant technical deficiencies, however. Its generator could not produce enough electricity to transmit signals more than about 5 to 8 miles. More seriously, there was a tendency for the sending and receiving index pointers to get out of synchronization, hopelessly garbling transmitted messages. Broken machines had to be sent back to New York City for repair. It was these deficiencies that led Myer to his decision to use traditional Morse key technology and attempt to hire trained telegraphers, a decision that led Secretary Stanton to dismiss him as chief signal officer. All of the telegraph train assets of the Signal Corps were turned over to the Military Telegraph Service, but they did not use the Beardslee telegraph due to its unreliability. At their peak of usage in 1863, there were 30 telegraph trains in the field.
Starting with the Tōkaidō Shinkansen () in 1964, the network has expanded to currently consist of of lines with maximum speeds of , of Mini-Shinkansen lines with a maximum speed of , and of spur lines with Shinkansen services. The network presently links most major cities on the islands of Honshu and Kyushu, and Hakodate on northern island of Hokkaido, with an extension to Sapporo under construction and scheduled to commence in March 2031. The maximum operating speed is (on a 387.5 km section of the Tōhoku Shinkansen). Test runs have reached for conventional rail in 1996, and up to a world record for SCMaglev trains in April 2015.
The alpha proposal projected that cost savings compared with conventional rail would come from a combination of several factors. The small profile and elevated nature of the alpha route would enable Hyperloop to be constructed primarily in the median of Interstate 5. However, whether this would be truly feasible is a matter of debate. The low profile would reduce tunnel boring requirements and the light weight of the capsules is projected to reduce construction costs over conventional passenger rail. It was asserted that there would be less right-of-way opposition and environmental impact as well due to its small, sealed, elevated profile versus that of a rail easement; however, other commentators contend that a smaller footprint does not guarantee less opposition. In criticizing this assumption, mass transportation writer Alon Levy said, "In reality, an all-elevated system (which is what Musk proposes with the Hyperloop) is a bug rather than a feature. Central Valley land is cheap; pylons are expensive, as can be readily seen by the costs of elevated highways and trains all over the world". Michael Anderson, a professor of agricultural and resource economics at UC Berkeley, predicted that costs would amount to around .
The railway was completely electrified in 2006. On April 18, 2007, the new CRH bullet train was introduced on the upgraded railway as part of the Sixth Railway Speed-Up Campaign. A day-time train D31 served the route, departing from Beijing at 10:50 every morning, and arriving at Shanghai at 20:49 in the evening, travelling mostly at 160–200 km/h (up to 250 km/h in a very short section between Anting and Shanghai West). In 2008 overnight sleeper CRH trains were introduced, replacing the locomotive-hauled Z sleeper trains. With a new high-speed intercity line opening between Nanjing and Shanghai in the summer of 2010, the sleeper trains made use of the high-speed line in the Shanghai–Nanjing section, travelling at 250 km/h for a longer distance. The fastest sleeper trains took 9 hours, 49 minutes, with four intermediate stops, at an average speed of 149 km/h.
The electrification of old horse trams came within less than a decade for the Holyoke Street Railway and in Massachusetts as a whole. When the railway's first electric cars appeared in 1891, at the time about a third of all street railway lines in Massachusetts had electric overhead systems. However by the turn of the century not only were these cars commonplace in the Holyoke system, they comprised more than 99% of such streetcar lines in the Commonwealth.
Much later, in the 1920s, a second and a third rapid transit railway systems were founded with the construction of the "Gran Metro" between Lesseps and the Plaça de Catalunya (part of the modern L3) and, two years later, the "Metro Transversal" (now part of L1). This third one was built between the Plaça de Catalunya and la Bordeta to link the city centre with the Plaça d'Espanya and Montjuïc, the site of the 1929 Barcelona International Exposition. These two later rapid transit companies contrasted with the first one in being inspired by the "Métropolitain de Paris" (from where the word "metro" comes).
As of the 2010s, at least 30 trolleybus manufacturers exist. They include companies that have been building trolleybuses for several decades, such as Škoda since 1936, Trolza (formerly Uritsky, or ZiU) since 1951 and New Flyer, among others, along with several younger companies. Current trolleybus manufacturers in western and central Europe include Solaris, Van Hool and Hess, among others. In Russia ZiU/Trolza has historically been the world's largest trolleybus manufacturer, producing over 65,000 since 1951, mostly for Russia/FSU countries. Škoda is Western and Central Europe's largest and the second largest in the world, having produced over 14,000 trolleybuses since 1936, mostly for export, and it also supplies trolleybus electrical equipment for other bus builders such as Solaris, SOR and Breda. In Mexico, trolleybus production ended when MASA, which had built more than 860 trolleybuses since 1979, was acquired in 1998 by Volvo. However, Dina, which is now that country's largest bus and truck manufacturer, began building trolleybuses in 2013.
The stop sits in an medium density residential area which was subject to urban renewal soon after the stop opened. The area on the Lewisham side of the stop featured various light industrial buildings. The Summer Hill side of the stop is dominated by the former flour mill complex, which underwent redevelopment. The mill provided the final traffic for the freight railway line, and the cessation of traffic after the mill's closure provided the catalyst for conversion of the line to light rail. The stop is located adjacent to the flour mill, within walking distance of Lewisham railway station on the Inner West & Leppington Line. The 2014 extension's Product Definition Report describes the positioning of the stop:
CRRC manufactures most of its bullet train carriages at its factory in Changchun. In November 2016, CRCC Changchun unveiled the first bullet train carriages in the world with sleeper berths, thus extending their use for overnight passages across China. They would be capable of running in ultra low temperature environments. Nicknamed "Panda", the new bullet trains are capable of running at 250 kmph, operate at -40 degrees Celsius, have Wi-Fi hubs and contain sleeper berths that fold into seats during the day.
The main public transport in major cities is the bus. Many cities also have a diverse system of metro and subway trains, the first of which was the Buenos Aires subte, opened 1913. The Santiago subway is the largest network in South America, with 103 km, while the São Paulo subway is the largest in transportation, with more than 4.6 million passengers per day and was voted the best in the Americas. In Rio de Janeiro was installed the first railroad of the continent, in 1854. Today the city has a vast and diversified system of metropolitan trains, integrated with buses and subway. Recently it was also inaugurated in the city a Light Rail System called VLT, a small electrical trams at low speed, while São Paulo inaugurated its monorail, the first of South America. In Brazil, an express bus system called Bus Rapid Transit (BRT), which operates in several cities, has also been developed.
Mount Victoria Railway Station Group is a representative example of a substantial railway station complex combining various types, periods and styles of buildings dating from the 19th Century and early 20th Century, each individually representing their standard designs and types.
After acknowledging the warning signal the train has to stay below the braking curve (German "Bremskurve") - fast trains may travel up to 165 km/h and they must reduce the speed to below 85 km/h after 23 seconds. Note that the operation of high speed trains beyond 165 km/h is not based on visual wayside signals or PZB inductors (using LZB or European Train Control System cab-signalling instead in Germany).
The inauguration of the Gatimaan Express by Railway Minister Mr. Suresh Prabhu on 5 April 2016 ushered the beginning of semi-high speed trains in India. The Gatimaan Express runs at the top speed of 160 km/hr from Delhi to Agra. With the great success of Gatimaan Express, the Indian Railways plans to start additional semi-high speed services along the Delhi - Bhopal / Chandigarh / Kanpur / Lucknow routes shortly. Railway minister Mr Sadananda Gowda mentioned in his Rail budget 2014 speech that the railways will start high speed trains at on 9 routes.Indian Railways is also testing to increase the speed of the Delhi-Mumbai Rajdhani express train. Dual locomotives are used for this purpose, one at each end. Thus accelerating and decelerating from both ends. Proposed increased speed will be 160kmph between Delhi-Mathura stretch and 130kmph for the remaining stretch. While Indian Railways is bringing bullet train from Japan, it is doing all possible things to cut down the cost for high speed rail operation by indigenously developing technologies.
Spain has the most extensive high-speed rail network in Europe, and the second-most extensive in the world after China. As of October 2010, Spain has a total of of high-speed tracks linking Málaga, Seville, Madrid, Barcelona, Valencia and Valladolid, with the trains reaching speeds up to . On average, the Spanish high-speed train is the fastest one in the world, followed by the Japanese bullet train and the French TGV. Regarding punctuality, it is second in the world (98.5% on-time arrival) after the Japanese Shinkansen (99%). Should the aims of the ambitious AVE programme (Spanish high speed trains) be met, by 2020 Spain will have of high-speed trains linking almost all provincial cities to Madrid in less than three hours and Barcelona within four hours.
In 1966, Yoneyama Industory, an agricultural machinery maker in Matsuyama, Ehime Prefecture, invented , a freight-only rack monorail system. It soon became widespread in mikan citrus orchards in the prefecture, and in other parts of Japan. Other makers also started to build similar systems. Later in 1990, a company called Chigusa developed a passenger rack monorail system. These rack monorails were first used to transport workers in construction sites or forests. However, from 1990s, public facilities such as parks also started to use the system. Kaho Manufacturing started to sell their "slope cars" in 1990.
"We designed the building from the inside out, not the outside in,” said Loretta H. Cockrum, Foram’s founder, chairman and CEO. “We wanted the most efficient office building ever designed, with no wasted space or wasted energy. This is a building of the future more than a building of the present. A lot of love has gone into that building, and a lot of pride."
This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and incorporation of one atom o oxygen into each donor. The systematic name of this enzyme class is N6,N6,N6-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating). Other names in common use include trimethyllysine alpha-ketoglutarate dioxygenase, TML-alpha-ketoglutarate dioxygenase, TML hydroxylase, 6-N,6-N,6-N-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase, and (3-hydroxylating). This enzyme participates in lysine degradation and L-carnitine biosynthesis and requires the presence of iron and ascorbate.
