Abstract (en)
[origin: EP0343150A2] In a switch (1) having a frog comprising a principal and a secondary moving tongue (3, 4), the principal and secondary tongues (3, 4) are formed using thick-web standard rail sections and shallower asymmetric blade sections are arranged as outer wing rails (5, 6) opposite the thick-web standard rail sections. <??>Preferably, the height of the shallower asymmetric blade sections (5, 6) is at the same time less than the height of the thick-web standard rail sections of the frog point (3, 4) by at least the height of the rail foot (9, 18) of the thick-web standard rail sections of the frog point (3, 4). <IMAGE>
