PROBLEM TO BE SOLVED: To economically execute the height adaptation of a railroad rail fastener assembly.SOLUTION: Adaptation means to be used in the case of adapting a railroad rail fastener assembly to a change in the height of a rail clip bearing surface (1A) of a railroad rail above a rail foundation (2) on which a railroad rail (1) is mounted includes a fastening device extension component (700) configured to provide an extension yield strength surface (701a) for transmitting a load from the foot part of the rail (1) to a fastening device (4A), and the extension component is provided with positioning means (701b) for removably positioning this on the fastening device, and the adaptation means further includes a side post insulator (500A) for exchange having an electric insulating yield strength face, and the adaptation means further includes a toe insulator (600A) for exchange being a body separate from the side post insulator, and the toe insulator for exchange provides an electric insulating member which can be arranged on the rail clip bearing surface of the rail foot part.SELECTED DRAWING: Figure 2A |
