The frog has two wing rails (1, 2) and a frog point (5) arranged between the rails, where each rail exhibits a break (26) in their longitudinal direction. A migration preventing unit (16) is arranged on both sides of the break of the rails. The migration preventing unit is screwed with bases of both rails and welded with the frog point.
