63-741: Alweg was a transportation company based in Germany known for pioneering straddle-beam monorails . Alweg was founded by Swedish industrial magnate Dr. Axel Lennart Wenner-Gren in January 1953 as Alweg-Forschung, GmbH (Alweg Research Corporation), based in Fühlingen , a suburb of Cologne , Germany . The company was an outgrowth of the Verkehrsbahn-Studiengesellschaft (Transit Railway Study Group), which had already presented its first monorail designs and prototypes in

126-423: A railroad double-crossover . Vehicle specifications are generally not open to the public, as is standard for rolling stock built for public services. An alternative to using a wye or other form of switch, is to use a turntable , where a car sits upon a section of track that can be reoriented to several different tracks. For example, this can be used to switch a car from being in a storage location, to being on

189-562: A faulty monorail from a confidence trickster at a wildly inflated price. The Monorail Society, an organization with 14,000 members worldwide, has blamed the episode for sullying the reputation of monorails, to which Simpsons creator Matt Groening responded "That's a by-product of our viciousness...Monorails are great, so it makes me sad, but at the same time if something's going to happen in The Simpsons , it's going to go wrong, right?" The 2005 feature film Batman Begins features

252-653: A load-bearing single rail and an external wheel for balance. A highspeed monorail using the Lartigue system was proposed in 1901 between Liverpool and Manchester. In 1910, the Brennan gyroscopic monorail was considered for use to a coal mine in Alaska. In June 1920, the French Patent Office published FR 503782, by Henri Coanda, on a 'Transporteur Aérien' -Air Carrier. One of the first monorails planned in

315-557: A manually operated monorail of limited but sufficient capacity for the transport of small timber and firewood in the Northern Surabaya forest district. In later years, this idea was further developed by L. A. van de Ven, who was a forester in the Grobogan forest district around 1908–1910. Monorails were built by plantation operators and wood processing companies throughout the mountains of Central Java. In 1919/1920, however,

378-829: A monorail, constructed by Bruce Wayne's father through Gotham City, that is part of the climax of the film. The monorail is also included in the spin-off video game . Blaine the Mono is a train featured in Stephen King 's The Dark Tower series of books and first appears in The Dark Tower III: The Waste Lands . Monorails have also appeared in a number of other video games including Transport Tycoon (since 1999), Japanese Rail Sim 3D: Monorail Trip to Okinawa by Sonic Powered , SimCity 4: Rush Hour , Cities in Motion 2 , Cities: Skylines in

441-401: A peak passenger flow of up to 7,000 pphpd (people per hour per direction) are possible. In a cable-propelled automated people mover system, a central station powers the system, and therefore the train has no on-board drive engines, gearboxes or brakes. A fixed grip assembly connects the train to the cable. The cable propels , accelerates , and decelerates the train. The system operation

504-528: A self-supporting steel guideway. It is a light steel guideway, which is possible because of the use of lighter trains. The track consists of an I-beam which forms the running and guiding surface. The guideway superstructure is a steel framework construction. The guideway does not require heating in harsh winter conditions. Steel adapters between the steel truss guideway and the concrete columns allow height adjustments to compensate for ground settlements. The track can span more than 67 m (220 ft). Because

567-777: A subway in Los Angeles . Alweg's technology was licensed in 1960 by Hitachi Monorail , which continues to construct monorails based on Alweg technology around the world. What was for decades the world's busiest monorail line, the Tokyo Monorail , was completed in 1964 by what was then the Hitachi-Alweg division of Hitachi, and today's busiest monorail system, Chongqing Rail Transit , is also based on Alweg and Hitachi technology. After Alweg ran into financial difficulties, Alweg's German operations were taken over by Krupp . Krupp wound up all Alweg operations by 1964. In

630-457: A wooden platform (in the full-scale project the trestle would have been concrete). A model train, built to 1/5 scale to test the vehicle concept, was capable of reaching speeds of up to 70 km/h. The full-scale project was expected to reach speeds of up to 300 km/h. In the latter half of the 20th century, monorails had settled on using larger beam- or girder-based track, with vehicles supported by one set of wheels and guided by another. In

693-438: Is because Chongqing is criss-crossed by numerous hills, mountains and rivers, therefore tunneling is not feasible except in some cases (for example, lines 1 and 6 ) due to the extreme depth involved. Today it is the largest and busiest monorail system in the world. In July 2009, two Walt Disney World monorails collided , killing one of the drivers and injuring seven passengers. The National Transportation Safety Board found

756-530: Is comparable to the Double Shuttle system in terms of capacity and frequency (headway). Either each train has its own haul rope or both trains are attached to the same haul rope depending on the application requirements (station configuration, system length, etc.). This system creates a circular train flow where more than one train moves in the same direction. The principle of this system is based on several rope loops which adjoin and overlap each other in

819-421: Is monitored from a central control room; there are no drivers, conductors or operators on-board. The evacuation system is based on an independent stationary diesel emergency drive that would pull a stranded train back to the station, eliminating the need for an emergency walkway. Trains like these can be also used for different purposes, such as moving trailers and barge loaders. The automated people mover uses

882-477: Is speeding towards a stricken bridge. The James Bond film franchise features monorails in three movies, all belonging to the villain. In You Only Live Twice (1967) there is a working ground level monorail inside the SPECTRE volcano base. During Live and Let Die (1973), a prop monorail is shown in the villain's lair on the fictional Caribbean island of San Monique. In the 1977 The Spy Who Loved Me there

945-584: Is the simplest configuration, with one train operating in both directions on one guideway track. The "Double Shuttle" configuration features two independent shuttle systems operating side by side on a double guideway track, each with its own haul rope and drive machinery. If one shuttle system fails or is closed for maintenance, the other system may continue to operate. This configuration is designed for system lengths up to 3 km (1.8 mi) and may have several intermediate stations. The frequency and passenger capacity of both shuttle systems depends largely on

1008-481: Is the straddle-beam, in which the train straddles a steel or reinforced concrete beam 2 to 3 feet (0.6 to 0.9 m) wide. A rubber - tired carriage contacts the beam on the top and both sides for traction and to stabilize the vehicle. The style was popularized by the German company ALWEG . There is also a historical type of suspension monorail developed by German inventors Nicolaus Otto and Eugen Langen in

1071-465: Is to place a moving apparatus on top of a sturdy platform capable of bearing the weight of vehicles, beams and its own mechanism. Multiple-segmented beams move into place on rollers to smoothly align one beam with another to send the train in its desired direction, with the design originally developed by ALWEG capable of completing a switch in 12 seconds. Some of these beam turnouts are quite elaborate, capable of switching between several beams or simulating

1134-567: Is under construction in Wuhu and several "Cloudrail" systems developed by BYD under construction a number of cities such as Guang'an , Liuzhou , Bengbu and Guilin . Monorails have seen continuing use in niche shuttle markets and amusement parks. Modern mass transit monorail systems use developments of the ALWEG beam and tyre approach, with only two suspended types in large use. Monorail configurations have also been adopted by maglev trains . Since

1197-709: Is using the BYD SkyRail design. Other significant monorail systems are under construction such as two lines for the Cairo Monorail , two lines for the MRT (Bangkok) and the SkyRail Bahia in Brazil . Modern monorails depend on a large solid beam as the vehicles' running surface. There are a number of competing designs divided into two broad classes, straddle-beam and suspended monorails. The most common type

1260-555: Is working monorail on the villain's supertanker (submarine dock). In 1987, Lego released a monorail among the Futuron Space line. Despite being the most expensive Lego set of its time (due to being massive and including electrical elements), it was very popular, with Lego releasing a Town themed monorail in 1990 and another Space monorail in 1994 among the Unitron line, as well as additional track. The monorail system

1323-597: The 1964–1965 World's Fair . This high-cost perception was challenged most notably in 1963 when the ALWEG consortium proposed to finance the construction of a major system in Los Angeles County, California , in return for the right of operation. This was turned down by the Los Angeles County Board of Supervisors under pressure from Standard Oil of California and General Motors (which were strong advocates for automobile dependency ), and

1386-454: The Bradford and Foster Brook Railway was built in 1877 and ran for one year from January 1878 until January 1879. Around 1879 a "one-rail" system was proposed independently by Haddon and by Stringfellow, which used an inverted "V" rail (and thus shaped like "Λ" in cross-section). It was intended for military use, but was also seen to have civilian use as a "cheap railway." Similarly, one of

1449-537: The Centennial Monorail demonstrated in 1876, in 1877 the Bradford and Foster Brook Railway began construction of a 5 mi (8.0 km) line connecting Bradford and Foster Township, McKean County in Pennsylvania . The line operated from 1878 until 1879 delivering machinery and oil supplies. The first twin-boiler locomotive wore out quickly. It was replaced by a single boiler locomotive which

1512-518: The Changsha Maglev Express ). However, it is argued that the larger width of the guideway for the maglevs makes it not legitimate to be called monorails. Some early monorails (notably the suspended monorail at Wuppertal , Germany) have a design that makes it difficult to switch from one line to another. Some other monorails avoid switching as much as possible by operating in a continuous loop or between two fixed stations, as in

1575-720: The Docklands Light Railway , Vancouver SkyTrain , the AirTrain JFK and cable propelled systems like the Cable Liner people mover which run on two rails. Monorail vehicles often appear similar to light rail vehicles, and can be staffed or unstaffed. They can be individual rigid vehicles, articulated single units, or multiple units coupled into trains. Like other advanced rapid transit systems, monorails can be driven by linear induction motors ; like conventional railways, vehicle bodies can be connected to

1638-553: The Interstate Highway System . Monorails in particular may have suffered from the reluctance of public transit authorities to invest in the perceived high cost of un-proven technology when faced with cheaper mature alternatives. There were also many competing monorail technologies, splitting their case further. One notable example of a public monorail is the AMF Monorail that was used as transportation around

1701-583: The Italia 61 exposition remained unused a few months after the exposition closed and was destroyed by a fire in the late 1970s, most probably set by vandals. The remnants of the system were scrapped in 1981, with the north station repurposed as an office building. In 1963, Alweg put forward a proposal to the Los Angeles County Board of Supervisors for a monorail system that would be designed, built, operated and maintained within Los Angeles County, California by Alweg. Alweg promised to take all financial risk for

1764-609: The Lartigue Monorail , used steam locomotives. Magnetic levitation train (maglev) systems such as the German Transrapid were built as straddle-type monorails. The Shanghai Maglev Train runs in commercial operation at 430 km/h (270 mph), and there are also slower maglev monorails intended for urban transport in Japan ( Linimo ), Korea ( Incheon Airport Maglev ) and China ( Beijing Subway Line S1 and

1827-802: The Lausanne Metro has grades of up to 12% and the Montreal Metro up to 6.5%, while VAL systems can handle 7% grades. Manufacturers of monorail rolling stock with operating systems include Hitachi Monorail , BYD , Bombardier Transportation (now Alstom ), Scomi , PBTS (a joint venture of CRRC Nanjing Puzhen & Bombardier), Intamin and EMTC. Other developers include CRRC Qingdao Sifang , China Railway Science and Industry Group , Zhongtang Air Rail Technology, Woojin and SkyWay Group . François Truffaut 's 1966 film adaptation of Ray Bradbury 's 1953 novel Fahrenheit 451 contains suspended monorail exterior scenes filmed at

1890-541: The Mass transit expansion pack of 2017, Planet Zoo and a rideable elevated monorail system in the 2020 video game Cyberpunk 2077 . From 1950 to 1980, the monorail concept may have suffered, as with all public transport systems, from competition with the automobile . At the time, the post–World War II optimism in America was riding high and people were buying automobiles in large numbers due to suburbanization and

1953-484: The Seattle Center Monorail . Current monorails are capable of more efficient switching than in the past. With suspended monorails, switching may be accomplished by moving flanges inside the beamway to shift trains to one line or another. Straddle-beam monorails require that the beam moves for switching, which was an almost prohibitively ponderous procedure. Now the most common way of achieving this

2016-695: The Transrapid and Linimo . Maglevs differ from other monorails in that they do not physically contact the beam while moving. The first monorail prototype was made in Russia in 1820 by Ivan Elmanov . Attempts at creating monorail alternatives to conventional railways have been made since the early part of the 19th century. The Centennial Monorail was featured at the Centennial Exposition in Philadelphia in 1876. Based on its design

2079-561: The elevated train systems of New York, Chicago, and elsewhere, a monorail beamway casts a narrow shadow. Conversely, monorails can be more expensive than light-rail systems that do not include tunnels. In addition, monorails must either remain above ground or use larger tunnels than conventional rail systems, and they require complex track-switching equipment. Under the Monorail Society's beam-width criterion, some, but not all, maglev systems are considered monorails, such as

2142-458: The maglev transport system at Birmingham Airport which was, at the time, the world’s only commercial maglev system. The technology was used for the new AirRail Link on the existing maglev guideway to replace the previous system and temporary bus-service shuttle that had been operating in the meantime. The automated people mover systems are based on cable -propelled technology. The manufacturer claims distances up to 4 km (2.5 mi) and

2205-519: The 1880s. It was built in the twin cities of Barmen and Elberfeld in Wuppertal, Germany, opened in 1901, and is still in operation. The Chiba Urban Monorail is the world's largest suspended network. Almost all modern monorails are powered by electric motors fed by dual third rails , contact wires or electrified channels attached to or enclosed in their guidance beams, but diesel-powered monorail systems also exist. Historically some systems, such as

2268-524: The 1950s, a 40% scale prototype of a system designed for speed of 200 mph (320 km/h) on straight stretches and 90 mph (140 km/h) on curves was built in Germany. There were designs with vehicles supported, suspended or cantilevered from the beams. In the 1950s the ALWEG straddle design emerged, followed by an updated suspended type, the SAFEGE system. Versions of ALWEG's technology are used by

2331-697: The 1960s there was a plan to build an Alweg monorail in the High Tatras in Slovakia. Monorail The term possibly originated in 1897 from German engineer Eugen Langen , who called an elevated railway system with wagons suspended the Eugen Langen One-railed Suspension Tramway (Einschieniges Hängebahnsystem Eugen Langen). Monorails have found applications in airport transfers and medium capacity metros. To differentiate monorails from other transport modes,

2394-536: The 1980s, most monorail mass transit systems are in Japan , with a few exceptions. Tokyo Monorail , is one of the world's busiest, averages 127,000 passengers per day and has served over 1.5 billion passengers since 1964. China recently started development of monorails in the late 2000s, already home to the world's largest and busiest monorail system and has a number of mass transit monorails under construction in several of cities. A Bombardier Innovia Monorail -based system

2457-515: The 2000s, with the rise of traffic congestion and urbanization, there has been a resurgence of interest in the technology for public transport with a number of cities, such as Malta and Istanbul , today investigating monorails as a possible mass transit solution. In 2004, Chongqing Rail Transit in China adopted a unique ALWEG-based design with rolling stock that is much wider than most monorails, with capacity comparable to heavy rail . This

The Thunderbirds February 1966 episode " Brink of Disaster " is about the financing and building of a high speed driverless cross-country monorail project. Two of the Thunderbirds-crew find themselves trapped on board the a monorail train, and with no possibility of escape, when it is discovered it

2583-452: The Monorail Society defines a monorail as a "single rail serving as a track for passenger or freight vehicles. In most cases, rail is elevated, but monorails can also run at grade , below grade, or in subway tunnels. Vehicles either are suspended from or straddle a narrow guide way. Monorail vehicles are wider than the guideway that supports them." Monorails are often elevated, sometimes leading to confusion with other elevated systems such as

2646-619: The United States was in New York City in the early 1930s, scrubbed for an elevated train system. The first half of the 20th century saw many further proposed designs that either never left the drawing board or remained short-lived prototypes. One of the most interesting projects created on the layout was the ball-bearing train by Nikolai Grigorievich Yarmolchuk. This train moved on spherical wheels with electric motors embedded in them, which were located in semi-circular chutes under

2709-500: The beam via bogies , allowing curves to be negotiated. Monorails are sometimes used in urban areas alongside conventional parallel railed metro systems. Mumbai Monorail serves alongside Mumbai Metro , while monorail lines are integrated with conventional rail rapid transit lines in Bangkok's MRT network. Unlike some trams and light rail systems, modern monorails are always separated from other traffic and pedestrians due to

São Paulo , Brazil, is building two high-capacity monorail lines as part of its public transportation network. Line 15 was partially opened in 2014, will be 27 km (17 mi) long when completed in 2022 and has a capacity of 40,000 pphpd using Bombardier Innovia Monorail trains. Line 17 will be 17.7 km (11.0 mi) long and

The supervisors voted down the proposal, mostly due to political pressures from Standard Oil of California and General Motors , which were strong advocates for automobile dependency . This move was greatly resented by famed author Ray Bradbury who supported the monorail project and resented the later move to build

2961-584: The first monorail locomotive was a 0-3-0 steam locomotive on this line. A high-speed monorail using the Lartigue system was proposed in 1901 between Liverpool and Manchester. The Boynton Bicycle Railroad was a steam-powered monorail in Brooklyn on Long Island , New York . It ran on a single load-bearing rail at ground level, but with a wooden overhead stabilising rail engaged by a pair of horizontally opposed wheels. The railway operated for only two years beginning in 1890. The Hotchkiss Bicycle Railroad

3024-483: The first systems put into practical use was that of French engineer Charles Lartigue, who built a line between Ballybunion and Listowel in Ireland, opened in 1888 and lasting 36 years, being closed in 1924 (due to damage from Ireland's Civil War). It used a load-bearing single rail and two lower, external rails for balance, the three carried on triangular supports. It was cheap to construct but tricky to operate. Possibly

3087-574: The geometry of the rail. They are both guided and supported via interaction with the same single beam, in contrast to other guided systems like rubber-tyred metros , such as the Sapporo Municipal Subway ; or guided buses or trams, such as Translohr . Monorails can also use pantographs . As with other grade-separated transit systems, monorails avoid red lights, intersection turns, and traffic jams. Surface-level trains, buses, automobiles, and pedestrians can collide each one with

3150-519: The guideway superstructure is a steel framework construction and do not have a solid track base, platform screen doors are used at stations on the system. The trains are bidirectional. The car is a self-supporting lightweight design with extruded aluminium box-type profile sections. The integral monocoque structure is bolted and riveted and joint connections are aluminium castings. The aluminium sections are made of high-grade, corrosion-resistant alloy . The undercarriage supports are integrated into

3213-662: The hand-operated monorails gradually disappeared and were replaced by narrow-gauge railways with steam locomotives as forest utilization changed. In the 1920s the Port of Hamburg used a petrol powered, suspended monorail to transport luggage and freight from ocean-going vessels to a passenger depot. Cable Liner The Cable Liner is a range of automated people mover products designed by Doppelmayr Cable Car for use at airports , in city centers , intermodal passenger transport connections, park and ride facilities, campuses, resorts and amusement parks . The design superseded

3276-534: The later proposed subway system faced criticism by famed author Ray Bradbury as it had yet to reach the scale of the proposed monorail. Several monorails initially conceived as transport systems survive on revenues generated from tourism , benefiting from the unique views offered from the largely elevated installations. Monorails have been used for number of applications other than passenger transportation. Small suspended monorail are also widely used in factories either as part of moveable assembly lines. Inspired by

3339-497: The legacy systems in use today. However, monorails gained little foothold compared to conventional transport systems. In March 1972, Alejandro Goicoechea-Omar had patent DE1755198 published, on a 'Vertebrate Train', build as experimental track in Las Palmas de Gran Canaria, Spain. Niche private enterprise uses for monorails emerged, with the emergence of air travel and shopping malls , with shuttle-type systems being built. From

3402-460: The length of the system, and the number of intermediate stations. The passenger capacity additionally depends on the capacity of the train. In this system, only one guideway enters each end station, but movable switches direct trains onto dual tracks between stations so they can pass one another en route. The bypass must be located approximately in the middle of two terminal end stations, and can form part of an intermediate station. This configuration

3465-409: The main line. The now-closed Sydney Monorail had a traverser at the depot, which allowed a train on the main line to be exchanged with another from the depot. There were about six lines in the depot, including one for maintenance. Rubber-tired monorails are typically designed to cope with a 6% grade . Rubber-tired light rail or metro lines can cope with similar or greater grades – for example,

3528-596: The monorail car. A surviving suspended version is the oldest still in service system: the Wuppertal monorail in Germany. Also in the early 1900s, Gyro monorails with cars gyroscopically balanced on top of a single rail were tested, but never developed beyond the prototype stage. The Ewing System , used in the Patiala State Monorail Trainways in Punjab, India , relies on a hybrid model with

3591-488: The other, while vehicles on dedicated, grade-separated rights-of-way such as monorails can collide only with other vehicles on the same system, with much fewer opportunities for collision. As with other elevated transit systems, monorail passengers receive sunlight and views. Monorails can be quieter than diesel buses and trains. They obtain electricity from the track structure, whereas other modes of transit may use either third rail or overhead power lines and poles. Compared to

3654-625: The previous year. The Alweg name is an acronym derived from Dr. Wenner-Gren's full name. Alweg is best remembered for their role in building the original Disneyland Monorail System at Disneyland , which opened in 1959, and the Seattle Center Monorail , which opened for the 1962 Century 21 Exposition . Both systems remain operational, with the Seattle Center Monorail still using the original Alweg trains which have traveled over one million miles. A third system, built in Turin for

3717-460: The stations. Every haul rope loop is supplied with its own drive and return machinery. In every station each vehicle of the train has to be disconnected from the current haul rope to the next haul rope in order to continue the circular and synchronized train flow. The haul rope loop change may occur only when all the trains are positioned at the standard stop position in the stations and are standstill and will be carried out during boarding/alighting of

3780-743: The two largest monorail manufacturers, Hitachi Monorail and Bombardier . In 1956, the first monorail to operate in the US began test operations in Houston, Texas. Disneyland in Anaheim, California , opened the United States' first daily operating monorail system in 1959. Later during this period, additional monorails were installed at Walt Disney World in Florida , Seattle , and in Japan . Monorails were promoted as futuristic technology with exhibition installations and amusement park purchases, as seen by

3843-482: Was a monorail on which a matching pedal bicycle could be ridden. The first example was built between Smithville and Mount Holly , New Jersey, in 1892. It closed in 1897. Other examples were built in Norfolk from 1895 to 1909, Great Yarmouth , and Blackpool , UK from 1896. Early designs used a double- flanged single metal rail alternative to the double rail of conventional railways, both guiding and supporting
