초록

The present invention generally relates to a railway or railroad track joint, and more particularly, to an improved electrically insulated bonded rail joint incorporating a non-conductive spacer in or associated with a rail bonding adhesive. The present invention also relates to a method for bonding such electrically insulated rail joints. The present invention provides more control over the spacing of the adhesive layer to achieve a stronger joint and more predictable and stable electrical insulation of a track circuit with improved bonding.
