Abstract (en)
[origin: CA3206574A1] The invention relates to a frog (10) and to a method for producing such a frog, comprising wing rails (16, 18) each having at least one railhead (62, 64) and one rail web (66, 68), and comprising a frog point (12) arranged movably between the wing rails, wherein, in the region of the frog point, a wheel transfer zone extends between the frog point and the wing rail with which the frog point is in contact. Separately from the frog point (12), each wing rail (16, 18) has a portion (20, 22) which extends at least over the length of the wheel transfer zone and which is made from a forged block.
