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. The rail bridge (20) reduces track closure time due to rail damage and associated costs and inconvenience.
