    摘要: The invention relates to a manganese steel insert to a railroad track switch point of the type designed to have a planar coupling system within both the web of the rail and the switch point of the insert, instead of the conventional curved coupling surface in use at the present. This is achieved by means of an attachment of the same material as the insert (or other steel) on the insert contact surfaces, thus achieving precision plane surfaces during the machining phase.

    摘要: In a rail switch arrangement in which an elongated rail is fixedly mounted on supporting structure and an elongated rail blade is moved on the supporting structure toward and away from a position contiguously adjacent the fixedly mounted rail, a sheet member of synthetic resin composition is fixedly secured to a bottom face of the rail blade and slidingly engages the approximately horizontal top face of the supporting structure during the movement of the rail blade.
