The travelling nut engages a ball screw. The travelling nut includes a slot. The travelling nut rotates with the ball screw when the body is in the first position. The key engages the slot when the body is in the second position. The travelling nut and the latch adjust a height of the deck in the auto rack car when the body is in the second position and when the ball screw is turned.
