  • Wayside signal apparatus with adjustable signal position
    Patent number: 7780121
    Abstract: A railroad wayside signal cantilever (10) including an arm (22) with a signal mounting apparatus (28) that provides a degree of horizontal movement of the signal (26) relative to the cantilever mast (12). The available range of locations for securing the signal on the arm is sufficiently broad to allow a single cantilever design to be used for a wide range of site-specific locations.
