• Implementation of the proposed truss track structure and its rail for the Unitsky high-speed transport system in accordance with the above method of its manufacture provides: reduction in the complexity of mounting the truss track structure; improving the reliability of the connection of the elements of the power structure of rail threads in a rigid spatial structure; unification of the elemental base of the whole construction; stabilization of operational and technical parameters throughout the transport system; stability (solidity) of the truss track structure; reliability and evenness of its rail threads; the smoothness and softness of the movement of the vehicle (not shown in the figure) for each farm span and throughout the transport system.
