ABSTRACT:
The present invention provides an isolator particularly adapted for use with a rail anchor utilized in an application where railroad rail is installed on concrete ties. The isolator protects the concrete tie from contact with the rail anchor caused by longitudinal movement of the rail due to train acceleration of deceleration or expansion and contraction due to temperature changes. In one embodiment, the isolator is comprised of a structural plastic material and includes a front face section and a rear face section. The front face section and rear face section each comprise a generally rectangular structure, having a top edge, bottom edge, and side edges. A center section joins the front face section and rear face section and forms part of the top of the isolator. In another embodiment, the front face section includes a top section and bottom section, with the top section having a lower edge projecting laterally at an acute angle from the bottom section. Similarly, the rear face section includes a top section and a bottom section, with the top section having a lower edge projecting laterally at an acute angle from the bottom section.
