From your link, Blondie:

He would be the third local train-derailment operator in a little more than three years to be diagnosed with apnea, which involves poor breathing during sleep at night that can lead to “excessive daytime sleepiness,” according to the National Heart, Lung and Blood Institute.

I remembered that this was suggested as the cause of the Hoboken crash. I wonder if train and subway operators are required to pass a physical. If so, maybe they need to require more thorough physicals. This could be a life-saver not only for passengers, but for the operators by uncovering a silent disease.
