Abstract
The mold, for casting an intermediate rail section, has risers (25) for the head sides with the under side cross section surfaces at the lower edges of the head flanks of the rail head (8). The risers extend upwards from the edges to give an entry cross section at the risers into the molding zone, according to the thickness of the rail web (7), to meet the expression 0.6 hL ≤ A ≤ 3.75 hL, where h is the height of the rail head, L the width of the welded joint and A the surface of the entry opening cross section.
