Abstract: A system for embedding a pair of rails of a railway track comprises a pair of field panels adapted for positioning opposite each other at outer sides of the rails and a gauge panel adapted for positioning between the rails. Each field panel has a side surface adapted to face its corresponding rail outer side and the gauge panel has opposite side surfaces adapted to face the inner sides of the rails. A first filler strip is associated with each of the field panels and a pair of second filler strips are associated with the gauge panel. Each of the first and second filler strips include a sealing portion that is adapted to contact one of the inner and outer rail sides and a mounting portion for connecting the filler strip to its respective panel. A U-shaped reinforcing member extends along a length of each filler strip mounting portion such that each filler strip is sandwiched between its respective reinforcing member and panel side surface.
