  • Patent number: 6266866
    Abstract: An improved cast insert for a railway frog has two extensions extending in substantially the same direction away from the body portion of the casting and the end of each of the extensions has a cross sectional profile corresponding to the profile of the head and web of a rail but including only one side of what would normally be the base of a rail. A frog assembly is made by providing such an insert, machining each of two rails to also remove one side of the base near the end of the rail and attaching the machined end of each of the two rails to the end of one of said extensions such that the sides of the rails from which the base has been machined away face one another.

  • Patent number: 6158698
    Abstract: A hollow tie assembly for rodding associated with moveable trackwork (such as in a switch or a moveable point frog) serves the function of a tie, houses and protects throw rods, lock rods and detector rods, is adapted to accommodate North American switch machines, and does not interfere with mechanical tampers. The rodding is housed within two elongated and spaced channels which are held in predetermined spaced relationship. Switch plates straddle the flanges of each channel and the moveable rails or points are mounted on the switch plates. Rod adapters and switch clip provide a sliding connection to the moveable rails or points. The rods are made of insulating material and the switch plates and associated components include insulation to avoid cross conduction between the rails.
