真空チューブ列車
1. vactrain; vacuum tube train
2. VactrainA vactrain (or vacuum tube train) is a proposed, as-yet-unbuilt design for future high-speed railroad transportation. It is a maglev line run through evacuated (air-less) or partly evacuated tubes or tunnels. The lack of air resistance could permit vactrains to use little power and to move at extremely high speeds, up to 4000–5000 mph (6400–8000 km/h), or 5–6 times the speed of sound at sea level and standard conditions.
