Abstract: A guardrail assembly for securing to a rail of a track has a plurality of post forming means and one or more rail means supported by the plurality of post forming means, each post forming means including locking means slidably insertable under the rail, clamping means adapted to engage against a first side portion of the rail and to be moved between a first position, where the locking means is slidably removable from under the rail, and a second position, where the locking means locks the clamping means to the rail, upright post means, and spacing means connected between the clamping means and the upright post means for locating the upright post means sufficiently remote of the rail to prevent a rail worker encroaching dangerously close to the rail.
