Abstract
A railway tie bed scarifier mounts on a tie remover/inserter machine. The tie bed scarifier is dimensioned and configured to widen the pre-existing channels left in the ballast through the removal of old ties. The tie bed scarifier includes a carriage moving between a raised travel position and a lowered work position, and a pair of tines reciprocating between a retracted position wherein they fit between the rails, and an extended position wherein they extend towards the sides of the ballast. A method of inserting a railway tie is also provided.
