Abstract

A vehicle for replacing selective ties in a road bed uses a conveyor system whereby ties may be picked up from on top of the rails. If the ties are to be used by the particular vehicle, they may be held by that vehicle. On the other hand, the conveyor system allows ties to pass over top of the vehicle such that the ties will be again disposed on top of the rails such that a following tie replacement vehicle may use the ties. By use of a tie replacement or inserter head having two tie clamps, one can more quickly remove an old tie from underneath the rails and replace the old tie with a new tie which has been picked up from on top of the vehicle. Electromagnets are used to hold the tie plates against the rails during the selective replacement of particular ties such that replacement of the tie plates is not usually necessary.
