Electromagnetic levitated and guided system is commonly used in the field of people transport, tool machines frictionless bearing and conveyor system. In the case of low speed people transport vehicles, the electromagnetic levitation offers the advantage of a very salient motion and of a reduced maintenance of the rail.In this work FEM based analysis and design of different structure of rail (g...

The rapid growth of transport requirements in China will incur increasing transport energy demands and associated environmental pressures. In this paper, we employ a generalized data envelopment analysis (DEA) to evaluate the relative energy efficiency of rail, road, aviation and water transport from 1971 to 2011 by considering the energy input and passenger-kilometers (PKM) and freight ton-kil...

Railroads play a key role in the transportation of hazardous materials in North America. Rail transport differs from highway transport in several aspects, an important one being that rail transport involves trains in which many railcars carrying hazardous materials travel together. By contrast to truck accidents, it is possible that a train accident may involve multiple hazardous materials cars...

Basically more than half of these accidents occur at public crossings, where active warning devices are in place and functioning properly. In most cases, accidents occurred when road users ignored the gates and passed through them or if they stopped on the tracks before the g...
