There is a crisis in ground transportation arising out of the increasing mobility of a growing population, heightened by the increasing mobility and consequent resource depletion of the world at large. Rohr Industries is committed to developing multiple ground technologies to satisfy transportation's varied needs. This paper discusses the company's diversification from aerospace into ground transportation, starting with rapid transit systems and leading to advanced transportation systems. The two most promising advanced transportation developments include an aerotrain, a tracked air cushion vehicle, and the Romag, a magnetically levitated and propelled vehicle. This paper reviews these events and describes in detail the two new developments.
