ABSTRACT:
In a railway trailer hitch, a wear resistant and crack resistant insert is removably attached to a fixed portion of the head which is subject to wear or cracking in service. The insert is made of a material which reduces or avoids wear and cracking of the fixed portion. If wear or cracking does occur, it tends to take place in the insert. An old insert can be easily and quickly removed and a new insert inserted into the head so that the hitch is not taken out of service to repair or replace the top plate.
