Abstract
A system is provided for sensing misalignment of a railroad signaling system. The railroad signaling system includes at least one railroad signal coupled to at least one elongated member adjacent to a railroad. The system includes at least one transmitter positioned within at least one elongated member, and at least one receiver positioned from each of said at least one transmitter within at least one adjacent elongated member to the at least one elongated member. More particularly, the system includes at least one electronic device coupled to each of a transmitter and each of at least one receiver, to sense detection of each transmitter by at least one receiver of at least one receiver indicative of misalignment of the railroad signaling system.
