Abstract: An apparatus for electrically insulating a pair of adjacent rail sections that form separate electrical signal circuits includes a pair of electrically insulating end posts positioned in a space provided between the adjacent rail sections. A metallic separator is disposed between the pair of electrically insulating end posts. Both the electrically insulating end posts and the metallic separator have a cross sectional configuration substantially the same as the cross sectional configuration of the adjacent rail sections. The adjacent rail sections are mechanically connected by a pair of connecting bars that are electrically insulated from and adhesively bonded to the adjacent rail sections. In another embodiment guard rail sections are insulated from each other by a pair of electrically insulating end posts positioned in a space provided between the individual guard rail sections.
