Railway or tramway rail fastening system and method of laying such railway or tramway rail

摘要

In the present invention, there is disclosed a railway or tramway rail (1) fastening system, comprising a shell (2) and a resilient fill (4) within the shell (2) for holding a railway or tramway rail (1) having a head (1A), a web (1C) and a base region (1B). Said shell (2) having an inner profile of open channel form to receive the rail (1), wherein said inner profile of the shell (2) at its upper, open side and at its lower, base side is shaped to hold firmly, through the resilient fill (4) the head (1A) and the base region (1B), of the rail (1). The inner profile of the shell (2) between its base and the open side is narrowed so as to form a detent or pinch point through which the base region (1B) of the rail (1) has to be passed upon insertion of the rail (1) into the shell (2)¿to retain the rail (1). Disclosed is also a method of laying such a railway or tramway rail (1) using the shell (2) with resilient fill (4) causing the rail (1) to be firmly held therein, the rail (1) being held securely in position by the combination of resilient fill (4) and the shell (2).
