Mag Tubes

Mag Tube (aka magnetic tube, shooter, Transplanet Tubes or vac trains) [1] are magnetic induction based e levator and tube transport systems designed for very-high-speed transportation. This technology was first published in a 1962 science fiction short story "Mercenary" by Mack Reynolds, where he mentions Vacuum Tube Transport in passing.

Using partly evacuated tubes and tunnels, Mag tube carriages travel at up to 6500 km/h. The carriages are held up against gravity by a magnetic levitation system. They are propelled by a pulse traveling just ahead of the carriage, effectively "pulling" it along. At distances of less than 1000 km, speed is held to 750 km/h; at less than 250 km, speed is held to 50 km/h. Mag tube technology is used for short distances in some shooter/verti shooters.

The largest networked Mag Tube System is found on Pluribus
