MAGLEV-COBRA: AN URBAN TRANSPORTATION SYSTEM FOR HIGHLY POPULATED CITYES


Abstract: This paper describes the construction and operation of a superconducting magnetically levitated vehicle applied to urban transportation. The technology was tested with a full-scale prototype named MagLev-Cobra. Comparisons with wheel and rail technology, high speed MagLev and other MagLev technologies are presented and application niches identified. The steps for commercialization will also be addressed.
Keywords: Magnetic Levitation, Superconductivity, Linear Traction, MagLev-Cobra, Urban Transportation.
Introduction
The need of high speed non-polluting transportation systems has drawn the world attention to MagLev trains that can travel at speeds of 600 km/h and use electricity as power supply. For connections up to 1000 km, high speed trains can offer advantages in terms of reliability, time, comfort and cost in comparison with airplanes and other transportation means <1>.
On the other hand, the need of efficient public urban transportation, non-polluting and with competitive construction cost is one of the priorities of the modern world, where great part of the population live in big cities. The MagLev technology also offers construction and operational advantages in this case <2>.
Research projects, prototypes and commercial applications are scattered worldwide. This paper presents an overview of the basic principles and applications of MagLev trains, focusing special attention on the MagLev-Cobra project. A prototype was tested in a full-scale 200 meters long line. Comparisons with other MagLev technologies are presented and application niches identified. The steps for commercialization will also be addressed in this paper.
