Abstract

A cross frog of a grooved rail junction plate having a cross frog tip movably arranged on a sliding plate, wing rails running along the same, as well as auxiliary rails that transition into connecting bars, which delimit a respective groove with an allocated section of wing rail. In order to adjust the cross frog tip within the desired range and to make possible a problem-free exchange in the case of a repair or upgrade with a simple design, it is proposed that the cross frog tip transition without connection into the auxiliary rails.
