Safety barrier for a railway track

A guardrail assembly for a railway track, comprising:

• (a) a plurality of post forming means, each post forming means including an upright post means, and
• (b) one or more rail means supported by the upright post means, each post forming means further including:
• (i) locking means slidably insertable under a rail of the track,
• (ii) 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, and
• (iii) 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,
• wherein one or more bracket clip is connected to a side of the upright post means furthest from the railway track and is adapted to support the rail means, the bracket clip comprising flexible jaws for snap-on engagement and snap-off disengagement of the rail means, and wherein the spacing means comprises telescopically engaging spacer portions connected together by a spring clip having a protruding head that is adapted to pass through overlapping apertures formed in the telescopically engaging spacer portions, and wherein a bracket clamp is connected to an end of the spacing means and is adapted to slidably engage the upright post means, the bracket clamp comprising a pivotal lock that, when in a first position, forces a pair of free ends of the bracket clamp toward each other for locking the position of the upright post means relative to the spacing means, and, when in a second position, releases that force and allows relative movement between the upright post means and the spacing means.
