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. Ribs extending from the front face and the rear face to aid in positioning the isolator. In another embodiment, the front face section and the rear face section each include positioning tabs projecting therefrom to aid in positioning the isolator.
