ABSTRACT:
A portable derail for installation on railway track to prevent a railcar or locomotive from passing beyond a fixed point, thereby protecting workmen and equipment against accidents, the derail being lightweight and portable so a workman can carry it from one location to another, and yet being designed to function effectively under severe loading conditions and resist any tendency to slide along the rail when subjected to impact.
