[6] Monorail

More used as a transportation system in industry than in cities, a monorail is a type of electric railway train that runs either above or below a single track. In factories monorails are used for moving equipment or materials from one part of a plant to another. In public transportation systems they have thus far been used only for hauling people for short distances.

One of the first monorail systems constructed was the Schwebebahn (suspension railway*) in Wuppertal, Germany. Completed in 1901, it consists of two-car trains hung from an elevated structure**. Much of the route operates over the Wupper River. The distance covered is 9.3 miles (15 kilometers).

This system, though it has proved safe and efficient, has not had many imitators. There are today only about three dozen monorails in the world, and none operates for a distance longer than 10 miles (16 kilometers). There is an 8.2-mile (13-kilometer) monorail in Japan running from Tokyo to the airport. It was constructed in 1964 on the occasion of the Summer Olympic Games. Although much newer in appearance than the one in Wuppertal, it also is suspended from an overhead beam***. A shorter line was built at Osaka for the World's Fair called Expo '70. There is a 1-mile (1.6-kilometer) monorail in Seattle, Wash., that was built for the 1962 World's Fair. Disneyland in Anaheim, Calif., and Walt Disney World near Orlando, Fla., both have monorail trains operating within their grounds. The systems connect the various parts of the parks with hotels and parking lots.

The Disney and Seattle monorails ride above a beam. This system was designed in the 1950s in Sweden by Axel L. Wenner-Gren. The trains pick up an electric current from a rail attached to the side of the beam.

Although they provide swift and quiet transportation, monorails have not yet been accepted anywhere for long-distance travel. In England the Greater London Council studied the monorail as an option for urban transport. It concluded that such a system offered no advantages over existing surface and underground lines. Among the objections to monorail systems cited by critics are the huge cost of constructing a system, its unsightliness in a city, and passenger inconvenience. Such a system in any city would have the high visibility that elevated trains now have in parts of New York City, Boston, Chicago, and other urban centers.

One of the few places in the world to invest in a monorail system in the late 1980s was Malaysia. The city of Kuala Lumpur approved a project to construct a 12-mile (20-kilometer) line.
