ROMAG
ROMAG was a personal rapid transit (PRT) system produced by the American company Rohr, Inc. It featured a linear induction motor that was arranged to provide both traction and suspension in a magnetic levitation system. ROMAG was developed from a wheeled system known as Monocab, originally designed by Edward Haltom and built to the extent of a test track by Vero Inc. in 1969. Rohr bought the design from Vero and converted it to the ROMAG, opening their own test track at their Chula Vista, California, plants in 1971. The Vero test system was later used as a display unit at Transpo '72. ROMAG was considered for use in Toronto's GO-Urban project, but lost to the very similar Krauss-Maffei Transurban. It was then selected for a deployment in Las Vegas, but funding fell through and planning stopped. Rohr abandoned development after the 1973–1974 stock market crash erased half of their corporate value and they returned to their core aviation interests. Boeing Vertol purchased the ...

Personal Rapid Transit
Personal rapid transit (PRT), also referred to as podcars or guided/railed taxis, is a public transport mode featuring a network of specially built guideways on which ride small automated vehicles that carry few (generally less than 6) passengers per vehicle. PRT is a type of automated guideway transit (AGT), a class of system which also includes larger vehicles all the way to small subway systems. In terms of routing, it tends towards personal public transport systems. PRT vehicles are sized for individual or small group travel, typically carrying no more than three to six passengers per vehicle. Guideways are arranged in a network topology, with all stations located on sidings, and with frequent merge/diverge points. This allows for nonstop, point-to-point travel, bypassing all intermediate stations. The point-to-point service has been compared to a taxi or a horizontal lift (elevator). Numerous PRT systems have been proposed but most have not been implemented. , only a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krauss-Maffei Transurban
Krauss-Maffei's Transurban was a 12-passenger automated guideway transit (AGT) mass transit system based on a maglev guideway. Development started in 1970 as one of the many AGT and PRT projects that followed in the wake of the HUD reports of 1968. Its selection as the basis of the GO-Urban system in Toronto in 1973 made it well known in the industry; it would have been the basis of the first large-area AGT mass transit network in the world. Technical problems cropped up during the construction of the test track, and the sudden removal of funding by the West German government led to the project's cancellation in late 1974. The Ontario government completed development and installation of a non-maglev version, today known as the Bombardier Advanced Rapid Transit. History AGT development The publication of the HUD reports in the US in 1968 led to a wave of developments in the mass transit world. Dozens of companies around the world started development of AGT systems from large t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transpo '72
U.S. International Transportation Exposition, better known as Transpo '72, was a trade show held on of land at Dulles International Airport outside Washington, D.C., for nine days from May 27 to June 4, 1972. The $10 million event, sponsored by the U.S. Department of Transportation, was a showcase for all sorts of transportation-related technologies. Over a million visitors flocked to the show from all over the world. According to the ''Wall Street Journal'', it was "the biggest show the government has put on since World War II."Rothschild 1972 Transpo hosted the world's largest air show, all of the new widebody airliners, high-speed trains and demonstrations of the latest automated guideway transit systems. In addition to featuring futuristic technology "Flying trains, square dancing helicopters and the fantasy of a wonderland," according to a news release, Transpo '72 covered all current modes of transportation as well. General Manager William J. Bird explained, "We want to emph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HUD Reports
The HUD Reports were a series of studies in mass transit systems, funded by the Urban Mass Transportation Administration (UMTA) department of the United States Department of Housing and Urban Development (HUD). The HUD reports were extremely influential in the development of the personal rapid transit (PRT) concept, small pod-like vehicles that automatically travel from point-to-point in extended networks. Their publication in early 1968 sparked off PRT development projects at dozens of companies around the world. In spite of intense interest in the early 1970s, political winds shifted and today there is only one HUD-inspired PRT system in commercial operation, the Morgantown PRT in West Virginia. History UMTA By the late 1950s it was becoming clear to urban planners that something was seriously wrong with the major cities in the U.S. The rapid increase in automobile ownership in the post-war period was providing citizens with unprecedented mobility, allowing them to leave the citi ...

Vietnam War
The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset.

Linear Induction Motor
A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects, whereas a conventional induction motor is arranged in an endless loop. Despite their name, not all linear induction motors produce linear motion; some linear induction motors are employed for generating rotations of large diameters where the use of a continuous primary would be very expensive. As with rotary motors, linear motors frequently run on a three-phase power supply and can support very high speeds. However, there are end-effects that reduce the motor's force, and it is often not possible to fit a gearbox to trade off force and speed. Linear induction motors are thus frequently less energy efficient than normal rotary motors for an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
