skyTran

The early magnetic levitation system, Inductrack, which SkyTran has replaced with a similar proprietary design, has been tested by General Atomics with a full-scale model.

[7] In this first version, the passive maglev coils are enclosed and supported by a light shell called a guideway that also captures the vehicles mechanically to prevent derailment.

Malewicki proposes a 3D grid design that avoids accident-prone intersections by grade separation, with guideways and their exit and entry ramps crossing above or below each other.

[9] The paper is a thorough description of the concept at that point, although some important features of the current skyTran design are only discussed as options, including magnetic levitation rather than wheels and hanging below the guideway instead of riding above it.

[10][11] It also described how a very light vehicle that can squeeze both surfaces of a track simultaneously could reliably achieve a 6-G deceleration, allowing it to brake safely to a stop from 100 miles per hour (161 km/h) in just 55 feet (16.76 m).

Unimodal has tested prototype vehicles on short guideway sections at NASA's Ames Research Center, in Mountain View, California.

[17] In June 2016, skyTran signed a memorandum of understanding in the United Arab Emirates for the study and implementation of a personal rapid transit system in Yas Island.

[20] In June 2019 a memorandum of understanding was signed between skyTran and the Roads and Transport Authority (RTA) of Dubai in the United Arab Emirates to develop a Sky Pod suspended transit system.

In September 2023, skyTran was shuttered and filed for bankruptcy due to no additional funding from Reliance Industries; even though a full-scale in-door prototype was within 6 to 9 months.
