A grooved rail core piece including a core piece intersection area formed by intersecting grooves as an overflow area. The core piece has two construction profiles with interconnected outer fishing surfaces (22,24) extending in a longitudinal direction. In order to enable the intersection area of the core piece to be renewed in a simple manner, the intersection-point area of the core piece includes an interchangeable insert (36) which is arranged in a recess in an at least positive fit, the recess being defined by the sections of the construction profiles and by the sections of the lining parts (30,32) disposed in the outer fishing surfaces (22, 24), and the insert is fixed by means of at least two wedge elements (38, 40) which can be clamped in the lining parts. The lining parts and the construction profiles are connected by means of at least one clamping element protruding there through in a non-positive fit.
Grooved rail frog (10) including a frog intersection region (16) formed by intersecting grooves (12, 14) as an overrun region as well as two construction profiles (18, 20), extending in the longitudinal direction of the frog and being connected with each other, with outer fishplate chambers (22, 24) with lining pieces (30, 32) arranged in the chambers, the lining pieces being connected non-positively with the construction profiles by means of at least one tightening element (34) penetrating the lining pieces and the construction profiles, wherein the frog intersection point region comprises an interchangeable insert (36), which is arranged non-positively in a recess, wherein the recess accommodating the insert (36) is delimited by segments of the lining pieces (30, 32) arranged in the outer fishplate chambers (22, 24) of the construction profiles (18, 20), and wherein the insert is fixed in place in relation to the lining pieces.
