Hmm… the train was apparently going about 70 mph 65 seconds before the turn, then accelerated to 106/107…
The engineer stated he tried to slow the train down for the turn… (what was he asleep?), then something about searching his bag afterwards to call 911.
Now he has no memory of the accident at all, because he had a concussion… (and a lawyer, is that related?).
Oh well…
News reports say that he has been tweeting about Engineer schedules and crew fatigue. If he did fall asleep, what was his sked like for the past two weeks?
Naval Air Training and Operating Procedures Standardization (NATOPS), the Navy Instruction that gives guidance for all things flight related says this:
88.3.2.1.1
CCrew Rest for Flight Crew and Flight Support Personnel
Crew rest is the non-duty time before a flight duty period begins. Crew rest
includes free time for meals, transportation and rest and must include an
opportunity for 8 hours of uninterrupted sleep time for every 24-hour period.
Crew rest does not begin until after termination of official duties and is
required prior to reporting for preflight preparations. Flight crew should
not be scheduled for continuous alert and/or flight duty (required awake) in
excess of 18 hours. If it becomes necessary to exceed the 18-hour rule, 15
hours of continuous off-duty time shall be provided prior to scheduling the
member for any flight duties. Flight and ground support personnel schedules
shall be made with due consideration for watch standing, collateral duties,
training, and off-duty activities. Crew rest can be reduced to less than 12
hours in order to maintain a 24-hour work/rest schedule, but a shortened crew
rest period (for example to maintain circadian rhythm) must always include an
opportunity for 8-hours of uninterrupted sleep.
NATOPS goes on to say in a Note:
As the time continuously awake duty time exceeds 16
hours, performance efficiency begins to drop. After
18 hours, performance efficiency rapidly declines to
75 percent of effectiveness or less. The loss of
effectiveness is manifested by lapses in attention,
increased reaction time, slowed information
processing, decreased vigilance, and increased error
frequency. Accident rates for just about every type
of human activity increase after 18 hours of
wakefulness, particularly during the night
“circadian trough” when sleep would normally occur.
Railroads would be well advised to review and adopt this section.
