The injured employee and a co-worker were moving a tank car loaded with molasses from the loading station to the designated side of the facility using a wheel loader to pull the rail car. The employees reached an incline and applied the handbrake. While they repositioned the wheel loader to push the rail car the remaining distance to their destination, the rail car started to move backward. The injured employee climbed onto the rear platform of the car to tighten the brake, but the rail car collided with the loader bucket and the employee suffered fractures to their right femur and tibia.
