Vactrain

A vactrain (short for vacuum tube train) is a proposed type of high-speed transport system where vehicles travel through partially evacuated tubes or tunnels. By operating in a partial vacuum, air resistance is drastically reduced, allowing for higher speeds than conventional ground transportation, theoretically up to 4,000 km/h (2,500 mph).
