The basic R.N. (Ressorts du Nord) clip and its modifications for use with insulated and welded rail and all types of cross ties are described. The clip consists of a heat-treated, manganese-chrome, spring-steel blade which is doubled back on itself and drop-forged so as to form an upper and lower leaf connected by a rounded portion in the shape of a spring "eye". The R.N. clamp for wooden sleepers differs from the clip already described in having a longer blade, so as to be less stiff and prevent fatigue of the coach-screw. The combination of rubber soleplates and R.N. fixings has been proved to afford a very strong and secure anchorage of the rail on sleepers of all kinds, resistant to the vibrations of express traffic.
