Abstract

A railway track crossing frog assembled to the rails by welding has end portions formed with sole pieces 4 to support the base flanges of the rails and lugs 5-8 to hold the rails in alignment with the runways 2, 3 of the crossing. The lugs 5, 6 and 7, 8 are spaced to engage the rail web and may be supported by transverse webs 19, 20.
