[USMA:24763] Fwd: Re: AW: Gauge Width : Maglev

[John Nichols]

Civil Engineers usually measure in per cent slope as it makes the maths easy and the number neat
so a 3% crossfall is easy a .0000456 radians crossfall is horrible.

Gauge is measured as the distance between rails.  Pitch is an angle or slope
of the two tracks from the horizontal.

If pitch is an angle or slope it should be measured in degrees, gons or radians, not in metres. I apologize for being so uncomprehending.
