    Abstract: The temporary rail bridge (20) of the illustrated embodiment includes a bridge number (20) that is coupled to a track rail (16) by screw clamps (24). Each of the screw clamps (24) includes an internal tensioning component such as a spring (58) that allows for fast installation of the rail bridge (20) and maintains continuous pressure engagement in operation.
