A rail clip to be used to fasten rail seals or flangeway fillers to a rail. The rail clip includes a generally U-shaped hinged clip with one or more hinges formed by two curved arms of the same or different curvatures and an elongated back. The elongated back is designed to fit between the foot of the rail and the ballast. One or more of the arms may be rotatable such that it is perpendicular to the elongated arm and the other arm, allowing the clip to be put in place. Once the clip is in place, the arm is rotated to the desired position and locked into place, holding each rail seal against the rail.
