If locomotive does not have a standby hotstart, its not a good idea to shut them down. When you restart an engine that big if it has cooled down you need to wait quite a while before you can put it under full loading again. All of the genesis has autostart, but even with auto start when the engine is shut down the cars wont have lighting or HVAC. That is where you need ground power, if the layover facility does not have wayside power then again, you wont be shutting the train down. In order for it to be cleaned and inspected for the next trip.
They probably only have one coach cleaner for the entire train, to save on costs. This probably takes a while. Even in the high speed rail building in NY amtrak employs one coach cleaner per car which takes about an hour to clean top to bottom at the least. On a turnaround clean like in DC takes about 20 minutes to garbage a set, freshen restrooms and turn seats. I am not sure whats involved and how anything works out west there as i have never been there before.

No good deed goes unpunished.
