Maglev question

[VeritechCEO]

Given the technology behind this transrapid technology, what kind of grades have maglev trains been tested on? I'm curious to know how steep a grade this kind of train can handle.

It's a good question, i dont think they have tested yet although they wouldnt need to be too steep due to the elivated nature of the rail, so i'd keep to regular rail grades to be on the safe side

Due to the technology a maglev can't slip back down a grade (the opposing magnet behind the train pushing the train forward would prevent this) so theoretically maglev can travel up any grade. Nasa have a space elevator on the drawing board that uses maglev technology this would be pracitly vertical and also are thinking about a maglev powered space shuttle launch system for this to work the track would have to be slanted to at least 30 - 40 degrees.

Here's a link for launch systems

Just to add, as a fundamental force gravity is far, far weaker than magnetism. A small magnet placed upside down can make a small metalic objext repell the force of gravity. (I knew my physics A level would come in handy sameday)
