A road safety rail system as claimed in claim 1 wherein one or more of the posts supporting the STE rails are adapted to fold. A road safety rail system as claimed in claim 1 wherein the twist in the FTE rail(s) occurs whilst maintaining a horizontal axis substantially at, or near, the same set height above ground leve A road safety rail system as claimed in claim 1 wherein the moving energy absorbing component further includes a brace element which diagonally extends at a predetermined non- orthogonal angle from the base of the impact head from a point adjacent the top of the entry point of the axial orifice to the at least one beam. A road safety rail system as claimed in claim 1 wherein there is provided two curved beams which connect the upright to the post detacher element the curved beams being positioned on either side of the impact and post detacher element. A road safety rail system as claimed in claim 1 or claim 5 wherein the impact head and associated beam(s) and post detacher element travel together as a unit along the rails of the system when a vehicle has a head on impact with the upstand of the impact head. A road safety rail system as claimed in claim 5 wherein following a head on impact from an errant vehicle the travel of the impact head along the rails, causes the STE rails to twist and bend in substantial conformance with the twist and bends of the FTE rails of the TES. A road safety rail system as claimed in claim 4 wherein the bracing element is attached to the impact head to stabilise the curved beam(s) and assist with guiding the FTE rail(s) and STE rails into the axial orifice of the impact head. A road safety rail system as claimed in claim 1 wherein the axial orifice includes a portion thereof with a profile which decreases in size from the rail entry point.
