Hence the different protocols needed for a 10 minute outage and a 3 hour outage.
You can't tell at the 10 minute mark whether or not power will be back in 10 more minutes, or in 3 hours.
In software incident management the rule of thumb is that at the n minute mark, in general, expected outage duration is 2n minutes.
But you can tell when 3 hours have passed and decide upfront - as a matter of policy - where to draw a line.
And at the 4 hour mark, the passengers were rescued. It would be ironic, of course, if the rescue train hit any one of the geniuses that smashed windows and started walking the tracks.
And where would you draw the line?
Once you detect that electricity supply is damaged and that it’s over 10 miles and you know how many trains have stopped moving … you know it won’t be 10 minutes. It can’t take long to figure out what trains have stopped moving and where electricity has been cut.
yes, because what if one of those people is touching the power rail? What do we know about the demographics of the people walking? How do we know they all made it out, or is someone lying down somewhere on the track?
That seems slanderous by the Union. They are suggesting that (likely a senior instructor) caused the collision and one of their members would have avoided it.
