Abstract
A tie replacement vehicle uses a tie feed arm to turn ties upon the main frame of the vehicle upside down such that they may be gripped by a tie inserter having a boom mounted below the main frame of the vehicle. The tie inserter has a tie clamp which may be shifted in the lengthwise direction of the vehicle in order to shift old ties out of the way. A tie pickup is mounted at each end of the vehicle for moving ties from the main frame of the vehicle to the rails. A conveyor system on the vehicle allows ties to be moved under the operator cab and engine.
