<p>A rail track arrangement has a rail (20), a sheath or shell (22) which receives the rail (20) and a resilient layer (26) between the sheath (22) and the rail (20). The sheath (22) has mounting points (30) at an upper surface of each side (22a, 22b) of the sheath (22), and upper side portions (32) of the resilient layer (26) extends laterally over the mounting points (30) at each side of the sheath (22) and engage with the mounting points (30). The upper surface mounting points (30) for the sheath (22) can be used for positioning of the sheath, and enable the sheath to be grouted into position in a one stage process. The mounting points (30) enable the sheath (22) to be installed without the rail, with high accuracy.</p> |
