A railway frog insert assembly comprises a casting defining the heel and toe sections of a frog. The portion of the casting intermediate the heel and toe sections consists of an integral spine extending between the heel and toe sections. The height of the spine is below the level of the flangeways in the vicinity of the point. An intermediate point section, the base of which is hollowed out, is removably seated over the spine. The top surface of the intermediate section defines the point, a small portion to the toe side of the point, a small portion to the heel side of the point, and the flangeways in the vicinity of the point.
