Abstract
A device and method for the replacement of railroad ties is disclosed. The tie extends laterally under two rails and is attached to the rails via tie plates. An example rail changing machine includes a tie changing boom moveable to one side of the two rails. The tie changing boom including a gripping assembly for clamping the railroad tie. The tie changing boom is moveable between a proximate position and a distal position from the one side of the two rails to grip the tie and remove the tie from under the rails. A kicker is located on the opposite side of the rails from the tie changing boom and contacts one end of the tie to move the tie toward the tie changing boom. A pair of tie plate clamps to hold the tie plates in place when the kicker moves the tie.
