Skytran (stylized as skyTran) is a personal rapid transit system concept. It was first proposed by the inventor Douglas Malewicki in 1990 and was under development by Unimodal Inc. A prototype of the skyTran vehicle and a section of track have been constructed. 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. In 2010, Unimodal signed an agreement with NASA to test and develop skyTran. skyTran had proposed additional projects in France, Germany, India, Indonesia, Malaysia, the United Kingdom, and the United States.
