No...that would be Pull - Pull mode. There is no "pushing" going on when handling a passenger train with locomotives on both ends.
Push - Pull is when you have a locomotive on one end of the train and a control cab on the other.

All I know is that Dr. Dolittle is the engineer.
Sorry, I just couldn't resist.
