Since all five MM&A engines were running when the train arrived at Nantes, any one of the five could have been left running when the other four were shut down.  The engine with the failed turbo was the lead and controlling unit, and that is the one they left running to keep the air pumped up.  Here is my question:  If they had shut down that controlling engine plus three others, and left the second engine running, would that be all the change required to have that second engine assume the role of pumping air?  Or, would control changes be necessary in order to switch the air pumping function from the first engine to the second?  If so, what would those control changes be, and how much time would they take?
