  • Patent number: 8066200
    Abstract: The invention is hollow structural members, a rail system based thereon and method of manufacturing such hollow structural members. Embodiments of the structural members may be hollow triangular prism-shaped with a cross-section that is triangular, isosceles, hexagonal or otherwise. Embodiments of rail systems based on hollow structural members are also disclosed. Embodiments of the rail systems disclosed herein may also include reaction assemblies for local dissipation of stresses due to thermal expansion of track materials.
