Track rail joint assemblies with nut and bolt fasteners are disclosed in which a nut restraining plate is interposed on the bolt between the nut and the joint bar. The plate is provided with one or more bendable tabs adjacent the bolt of hole which are bent away from the joint bar against the nut after the nut has been tightened down to effectively lock the nut into position and prevent loosening rotation tended to be caused by vibrational forces of railroad equipment passing over the joint. The plate is formed with the tabs slightly bent to permit bending tools to be slipped over the tabs when the plate is in position under the tightened down nut.
