ABSTRACT:
A tie replacing system is adapted to replace worn ties in a railroad track of the type including longitudinally extending metal rails supported on wooden cross ties by metal tie plates and a gravel ballast roadbed supporting and at least partially enclosing the ties. The system includes a tie biter-tie plate holder assembly comprising a pair of opposed jaws each including a plurality of teeth positioned at spaced intervals across the entire width of a worn tie. Upon closure of the jaws, the teeth function to remove any portion of the worn tie which projects above the under surfaces of the tie plates. The jaws also include tie plate gripping members which engage the tie plates corresponding to the worn tie and thereby retain the tie plates in engagement with the under surfaces of the rails.
