Fuel costs can be controlled through hedging. But when you take out the highs, you are also taking out the lows. So it won’t lower fuel costs, but it will control them and make them knowable.
Breakdowns can also be controlled and made knowable. With proper data management, and knowledge of maintenance levels, there shouldn’t be any surprises.
So there’s someone that can see in the future when a locomotive craps out, causing the train sit on a track, blocking crossing for hours or days?
I must have missed that training when I was working for one of the railroads.
