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 element (3) is of molded steel, of which at least the two ends (3A and 3B) on the point side and the two ends (3C and 3D) on the heel side are shaped as a rail profile, but only the rail profile of the two ends (3A and 3B) effectively serves for rolling. The non-molded element (4) is mainly made up of parts (5 and 5') produced integrally as rails and connected to the two ends (3C and 3D) on the heel side of the molded part (3). Neither the rail profile of the two ends (3C and 3D) nor the rail profile of the parts (5 and 5') effectively serves as rolling surface. The moving point (1) is produced integrally as rails of which all the upper faces effectively serve as rolling surface.
