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.

The invention relates to a points or crossing component (200), comprising a basic component (202), an exchangeable component (206), at least one releasable connection (216, 218, 220) by means of which the exchangeable component (206) can be connected to the basic component (202) and at least one sensor (244) for monitoring the quality of the releasable connection, wherein, in the sensor (244), when a rail vehicle travels over the points or crossing component (200), a signal is generated that is representative of the quality of the releasable connection. For reliably detecting a connection that is in the process of becoming released, the invention proposes that the sensor (244) is arranged in the basic component (202) and is fixedly connected thereto.

Abrégé

The invention relates to an arrangement for holding down a rail (14) having a rail foot (20), such as a stock rail, comprising a base (18), such as a slide chair plate, tongue roller plate or wheel guide plate, a plate element (16), such as a slide chair or counter bearing, detachably arranged on the base, a spring element (10) holding the plate element on the base, and a first and a second abutment for tensioning the spring element. To enable the rail to be held down with structurally simple measures and at the same time to achieve ease of maintenance and servicing, it is provided that the first abutment is a section (78) of the plate element (16) or extends therefrom, running in the region remote from the rail foot, in that the second abutment is an eccentric element (12) which preferably extends in the longitudinal direction of the rail (14) and is arranged rotatably in a receptacle (46) arranged between the rail foot (20) and the first abutment and starting from the base (18), and in that the spring element is designed to be supported on the rail foot (20).
