An employee had just driven a vehicle into a rail car and was going to start a new deck. He was moving a bridge plate fixture that enables them to drive from one rail car to another when the weight of the plate pulled him off the deck. He fell and struck his head on the ground. He also struck the piece that secures cars together and sustained a wound to a cheek, two back fractures, ruptures to the kidney and spleen, internal bleeding, and severe bruising to the right arm and side.
