‘Hyperloop’

Hyperloop is a new mode of passenger and freight transportation that propels a pod-like vehicle through a near-vacuum tube at airline speeds. The pods accelerate to cruising speed gradually using a linear electric motor and glide above their track using passive magnetic levitation or air bearings. The tubes can go above ground on columns or underground, eliminating the dangers of grade crossings. It is hoped that the system will be highly energy-efficient, quiet and autonomous. Wikipedia
