Patent

CA 2314481

An improved cast insert for a railway frog has two extensions extending in substantially the same direction away from the body portion of the casting and the end of each of the extensions has a cross sectional profile corresponding to the profile of the head and web of a rail but including only one side of what would normally be the base of a rail. A frog assembly is made by providing such an insert, machining each of two rails to also remove one side of the base near the end of the rail and attaching the machined end of each of the two rails to the end of one of said extensions such that the sides of the rails from which the base has been machined away face one another.
