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.
