Vactrain - Wikipedia

A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. Reduced air resistance could permit vactrains to travel at very high ( hypersonic ) speeds with relatively little power—up to 6,400–8,000 km/h (4,000–5,000 mph).
