Abstract:
In a switch including a switch frog (1) with a movable frog point (2) and wing rails (5, 6), wherein the wing rails (5, 6) in the region of the frog point (2) each have a rail profile which is lower than that of a standard rail, the wing rails (5, 6) are designed as Vignol rails whose region configured with a lower rail profile is produced by metal-forming departing from the Vignol rail profile.
