Bump - Still looking for a guestimate on what it would take, time- and speed-wise, to do that kind of damage...

Yes.

Am I interpreting that last picture right? It looks to me like the rails were softened by the intense heat, and the sheer weight of the locomotive pressed into them, as opposed to the original post where spinning wheels burned into them.

This is the one, but the wheels weren't turning. Plastic (composite) ties contributed to the fire.
tree68 This does beg the question: How long would it take for such damage to occur? What kind of speed of rotation?

I may be mistaken, but I remember this one,or a similar photo taken in the aftermath of a very sad event in South Alabama some years back.
It was on the NS B'ham to Mobile line, and invoved the death of at least one crewman and at the time the serious injury by burn of the second crewman? I can't remember all the details, but it was a multi-engine power set and a burning trestle.

Continous Welded Rail, too - lots of fun to cut out the damaged pieces opposite each other and field-weld in replacement 'patches', including the necessary thermal adjustments - especially if in a hot or cold season . . .

Thanks Balt. That sounds plausible.
Euclid What was the actual cause for this wheel slip damage shown in the photo? If the actual cause is not known, what would be possible causes?

My guess -
Relatively large multiple unit consist (5 or more units) - a mix of working and shop bound units - a unit 'back in the consist' doesn't respond to the engineers controls when stopped for a period of time (most likely at a Stop signal) where inspection of the train isn't necessary. A lone unit continues to operate in a 'run' position with the rest of the train stopped; most likely some kind of defect in the MU cable or MU connections with that particular unit.

So this is that Positive Train Control I've been reading so much about.

A few passes with the rail grinder and it will be as good as new.

I thought maybe it was a new signal system...

I've seen similar images, usually involving a Diesel that wasn't properly secured and spun itself into a mess whilst unattended.
I've been over track on a grade that has had similar, but far less deep burns. Rather like rumble strips...
No, three-phase electric power, and the train stalled at night so the engine crew did not realize that the train was not moving (as in the GN's first Cascade Tunnel).

Rumble strips to wake up drowsy head-end crews?
First - concrete ties. Now "flared" rails. What will they think of next?

Well Hello Mr. Lion. Long time no roar. Seen that done before. Driver didn't put it in park. Does not make track gang happy.
