That's never a good thing.

Anyone? Could have active Positive Train Control avoided this incident?

No. PTC only enforces speed limits and stopping. No technology exists to scan the track ahead for obstructions in front of a train, though in the UK (probably elsewhere too) there is technology to automatically radar scan grade crossings to ensure they are clear. That wouldn't have helped here though.

Mind you, there are rock slide fences (in the US) which automatically drop a signal or light some other indication trackside that a slide has been detected. But they're only installed in vulnerable areas due to cost.

Initial reports were saying this was a "freak accident".

IIRC there are rock fences with alerters. If the fence gets broken, a short circuit causes a forced RED several blocks back, and in CTC territory alerts dispatchers.

I think Mr. Norman posted that with his tongue planted firmly against his cheek. Might be interesting, though, to see which congress critters and other Amtrak bashers use this accident to fault Amtrak for not having PTC installed up there in the woods of the Green Mountain state.

I really didn't; Mike. I just wanted to put this incident into either of these groups:

Casselton
Galena
Lynchburg
Maryville
Northfield (apparently)
Trinity

or this:

Chatsworth
Goodwell
Red Oak
Frankford Jc.

But Mike's point is well taken regarding the reaction that some "critter" will soon trumpet.

Impossible to state with any certainty at this point which group that would fall into - if any. You have the extreme possibilities of (a) huge boulder falls onto track a second before the train comes (neither group); (z) routine trackside inspections that could have foreseen it canceled so the danger was missed (2nd group). And everything in between.

I hadn't realised just how bad this derailment was.
