ABSTRACT:
Disclosed is a method for forming electrical interconnections between railroad track components and signal conductors/lines. In one arrangement, an electrically conductive adhesive is utilized to electrically interconnect a signal conductor to a railroad track component. In another arrangement, a clamp is utilized in conjunction with the electrically conductive adhesive that forms the electrical interconnection. The clamp maintains the signal conductor in direct contact with the surface of the railroad track component while the electrically conductive adhesive cures. In these arrangements, the use of the electrically conductive adhesive allows for making an electrical connection with a railroad component without penetrating the structure of that component. In a further arrangement, a hollow tubular connector is utilized to electrically connect two signal conductors associated with railroad track components. An interior of the tubular connector is at least partially filled with an electrically conductive adhesive prior to inserting the ends of the signal conductors therein.
