Mag-lev carriage

A mag-lev carriage was a type of vehicle used to carry passengers and cargo along an orbital tether. It used magnetic levitation to propel itself into orbit.

In 2373, Tuvok, Neelix, and several Nezu used a mag-lev carriage called Alixia to rise above the ionosphere of a Nezu colony planet under surreptitious attack by the Etanians, so as to contact USS Voyager for rescue.
