ABSTRACT:
A process for producing a crossing frog with moving point (1) for very long railway switches incorporated in long welded rails. The frog also comprises a cradle (2) in two elements (3 and 4), one molded and the other not molded. The method comprises welding, on a point side of the frog, the molded element (3) of the cradle (2) to the rolling rails (7) of an intermediate track of a branch, fixing parts (5 and 5') to the moving point (1) so as to form the non-molded element (4) of the cradle (2); rigidifying the non-molded element (4); interconnecting, by means of a non-welded joint, the subassembly formed by the molded element (3) welded to the rolling rails (7) and the subassembly formed by the non-molded element (4) formed by the parts (5 and 5') and the moving point (1), and finally, welding the moving point (1) to the rolling rails (9) on a heel side of the frog.
