摘要：
A rail anchorage has a housing in which is received resilient material for bearing on the flange of a rail that the anchorage is to secure. The housing is formed to exert a wedging action on the resilient material when the material bears on the flange, and preferably also when the material is otherwise unloaded. In use the wedging action increases as the force placed on the resilient member increases.
