That commute might get a little harder...

When the commuter train crashed in California didn't the ntsb say it was fatigue even though the engineer was sending text messages up until seconds before the crash, and the first thing they did was drop the duty time for train crews?

The answer was 'yes'. As the NTSB pointed out too, many people use conversation to stay awake in cars, and pilots should consider it as well as a fatigue mitigation strategy, provided it doesn't detract from their duties. However, as I write this, NASA is testifying that 'conversation usually requires attention, thus detracting from situational awareness'. So, consider talk to reduce fatigue, but not enough to detract from situational awareness.
It should be noted that the direct physical events that caused this accident (retardation of the throttle, flap extension, gear extension, prop pitch change, shaker, control column movement, partial throttle increase, pusher, rudder pedal movement, flap retraction) did not occur in the midst of conversation.
Lets see, wake up at 4am, 2am on my body clock. Not uncommon at the "regionals" these days whose flying consists of flying in the region of the entire United States. Anyway, wake up at 4 am, fly 2 hours, sit for four hours after flying that 2, then fly 3 hours, sit 2 hours, then fly 1 hour to an 8 1/2 hour sit (overnight) at a hotel, repeat.
I'm not talking about day 1 of a trip with a commute in on that day, I'm talking about days 2 and 3 of many "regional" type 4 day trips.

Her schedule was likely more fatiguing than any regional schedule (even the worst ones are not a 36 hour duty day).
The problem is the public doesn't hear about the majority of commuters, but only about this one, which was abnormal. The public only knows the most sensational aspects of reality.

I would opine the problem is much more broad in nature. All these events are merely symptoms of the problem. In short, the airline business model is broke - plain and simple. The companies simply cannot make money on a long-term sustained basis unless of course you are a fuel-hedge brokering airline and that is more of a credit to fuel hedging not the airline model. As a result airline management (notice I didn't write leadership) does everything it can to bust into labor which in many cases ultimately includes safety whether they want to admit it or not. Meanwhile, same management has no problem robbing the corporate coffers to ingratiate themselves and their grandchildren. So what is the solution? Re-regulate the airlines. They are nothing more than a utility anyway with one exception -- utilities make money.

Yes, but the accident FO awoke in the morning in SEA, then started her commute that evening (or that was my understanding from the testimony in front of the NTSB hearing yesterday). The NTSB and FAA believe she had over 36 hours since her last full sleep. She slept on her SEA-MEM leg, as well as in MEM. How well was she rested @ the time of the accident? We'll never know for sure.
I don't consider that "full".

You missed the point. Lots of pilots go a FULL 4 day trip without getting a "full" sleep cycle. Regardless of whether they commuted in or not. I know on nights 1 and 2, or 2 and 3, or whatever combination, I've had less then 6 hours of sleep on BOTH nights. I don't know what you consider a "full" sleep cycle.
