摘要：
A railway or tramway rail fastening system includes a shell (2) and a resilient fill (4) within the shell for holding a rail (1), the shell having an inner profile open channel form to receive the rail, the inner profile being shaped to hold firmly, through the fill (4), the head and base region and/or an intermediate portion of the rail. The arrangement is such that pinch points are produced which hold the rail in place.
