  • Patent number: 8882050
    Abstract: A railway track barrier system that includes a barrier extending along a rail adjacent a switch having an upper edge adjacent a rail head disposed within a wash zone thereof formed of deflector elements movable relative to one another permitting railway vehicle wheel and wash contact during train passage without barrier dislodgement or damage. The barrier is formed of a deflector acutely inclined toward the head and a downwardly extending skirt that conforms to uneven railway bed and tie surfaces. A preferred barrier is formed of oppositely extending brushes removably attached to a mounting bracket. The bracket can be attached to a hinge assembly that releasably latches the barrier in an operating position and that can be unlatched permitting the barrier to be swung away from the rail to an inspection position. A hinge pin with a manually graspable handle can be removed to detach the barrier for storage.
