Unless something miraculously caused the brakes to fall off from all the axles of the train, it will be generally very hard to blame it on the brakes. They should be tested as part of the thorough investigation, but I would not say it is such a "hot spot" to look for when listing possible causes of mechanical failure.
When was the last time there was an actual brake failure, either in freight or passenger service?

Excluding the runaway in Canada, which was human-caused, it's a very very very rare event.

I was there about a week and a half ago and they still were...quite fun since they were playing musical tracks with the train I was catching between 4 & 7 -_-

Undiagnosed sleep apnea.

Google the sleep apnea.

It takes at least an over night sleep with sensors on the body and maybe even a camera. I am a Vet and the VA put a digital device on me with all kinds of sensors. I have a slight case of it. Stepson has it. A former boss had it. He could easily fall asleep in his office chair. Couple times I passed his house on way home from work and would see his car front up against the garage door and his brake lights on. Still in the car asleep. He mentioned to us it surprised him.

News on Google USA. Hate posting news articles anymore. Too much garbage.

I am not surprised that this could have been a possibility. Not at all.
The engineer of a commuter train that slammed into a station going double the 10 mph speed limit, killing a woman, suffered from undiagnosed sleep apnea, his lawyer said Wednesday, and a U.S. official told The Associated Press that investigators are looking at it as a potential cause.

Well that's the default answer to everything. And claimed only by his lawyer, not any actual fact from an actual investigation. It isn't a conclusion and hasn't been determined to be a cause. As such, I don't even believe it as a factor.

Plus the lawyer, with his case of premature oral ejaculation, has now probably been excluded from anymore NTSB meetings regarding his client.

Should they? Where do you draw the line? They don't screen pilots or any other profession I'm aware of. Many of which work way worse hours.

Wasn't implying that they should or shouldn't...merely inquiring. I believe people who were designated to be at risk with a certain neck circumference (as those who are overweight are more at risk to suffer from it) were screened at MN and NYCT...though people who actually work there can correct me if I heard wrong...wasn't sure if that ended up being an agency crackdown/CYA measure or a regional thing.

I.E. is the NTSB/FRA/ some other agency going to come back at NJT and say "Well Metro-North had an accident caused by previously undiagnosed sleep apnea, why did you not react to the findings and screen your engineers for the same?"

Exactly my point as this seemed to keep surfacing as time went by.

I think it was added only a couple or three years ago.

meanwhile in Canada they are finally reducing hours of service from 18 hours per day to 12 ?? go figure.
