Why does Big Boy 4014 have a diesel engine?

If the diesel engine referenced is the modern diesel electric locomotive that has been accompanying 4014 in its travels, my understanding is that Union Pacific utilizes it to assist with overall fuel efficiency and to provide regenerative braking. This helps with operating costs and provides a better level of safety.
