Abstract
A rail-transportation system had a longitudinally elongated rail assembly along which extends a longitudinally moving traction element connected to a plurality of longitudinally spaced cars riding on the assembly. The rail assembly consists of upper and lower longitudinally extending rails interconnected by struts and normally formed thereby into a rigid framework or box-beam construction. The car has a car body to one transverse side of the rails, an upper wheel to the other transverse side of the rails and riding on the upper rail, and a lower wheel to the one side of the rails and bearing on the lower rail in a transverse direction opposite that of the upper wheel. The car may have inner and outer frames connected together by a parallelogrammatic linkage connected to a guide rail between the upper and lower rails to maintain a load-carrying platform of the car horizontal even when the various rails are all inclined to the horizontal.
