A system for securing a rail to a concrete railroad tie employing an improved insulator spacer that improves the resistance of the insulator spacer to the crushing deterioration induced by laterally-directed compressive forces during service. The improved insulator spacer has at least one composite insert Located in an area that is subjected to high compressive loads in service. The composite insert or inserts are sufficiently electrically insulating to operably electrically insulate the rail the improved insulator spacer is in contact with from the shoulder insert the improved insulator spacer is also in contact with.
