So we cannot yet conclude that the rail that was bent by the truck in Kansas was the same bent rail that derailed the Amtrak train.
I would like to hear a little more about the truck driver, how he bent the rail, and what he did next.
Yes, how do you manage to bend a rail when driving a truck?

Take a look at the front bumper - hitting something like track structure at 30-40 MPH or more could easily shift the track.

I suspect that we have our answer.Johnny, I've watched section men straighten out track segments with the bucket end of a Speed-swing just by pushing against them. It would be no problem for a truck bumper like that, whacking either the ties or the rail, to cause the damage needed to derail the train.

Thanks to Chris / CopCarSS for my avatar.
Murphy Siding Deggesty Yes, how do you manage to bend a rail when driving a truck? Bend a rail, or simply push the track and ties over enough to cause problems?

I would make a somewhat 'educated guess" (?)
Most of the OTR truck bumpers are generally stamped from lighter gauges of steel.
Out here, you see large numbers of OTR units, on which have been installed what is sometimes locally referred to as "Bambie Bumpers". {Items made of steel and tubing]. Obviously, they are in-place to stop damage to a trucks front cap (Hood assembly), which is generally, moulded out of fiberglass. The repair or replacement of which, can run into numbers in excess of $1,500+ K.
Generally, trucks that get hung on crossings are due to an extremes of elevation between road/driving surface, and the elevation of the track(s). Landing gear 'feet/pads' are a usual culprite. Some drivers fail to retract them up as far as possible. The next is the low-riding trailer's frame rails- Low Boy- style are massive constructs, and with a little speed can really make' a hit' on a track structure. The 'possum bellys'[Van-style \-Moving vans, Drop frames,etc.] are another, but much lighter construction, except in their landing gear. The crossing with a raised elevation can cause these to get 'high centered', and may require a wrecker to move them off the offending crossing--or an approaching locomotive !

Two things - from the opposing highway traffic, there are a lot of 18 wheel stock trucks as the normal traffic. At the time the video was made the railroad was prepared for a tie & surfacing gang to begin working in the not too distant future as there are ties laid out along the right of way.
It is a painful process for this story to unfold. In some of the description, it sounds like a truck crossed the tracks without there being any crossing in place. It implies that the truck was some sort of monster off-road Ag truck that simply damage the rails by driving over them.
But the photo in the link does not show an unsually large, off-road truck. It shows a relatively small, single axle highway truck with a feed box. The only way I could see that moving the track would be if it snagged the rail at some speed of say 10-20 mph. I wonder what circumstances would have produced that scenario. Even with that strong bumper, I would expect an imact collision to produce some damage to the truck.

Track, subjected to side pressure, can be move out of alignment without massive pressures. The 'old time' section gang of 8-10 men with lining bars working together could move track without problems.
Here a coal truck has moved track for the NS - somewhat more energetically than the feed truck in Kansas.

Note Balt's post and image - that truck was empty, and had detached one rail from the ties before pushing the track out of alignment.
There is definitely damage to that after-market bumper. With the usual profile of track structure, the ties would easily be at bumper level (note the video of the line from a couple of years ago).
It's not a reach to conclude that said truck could have jogged the track out of alignment. At normal Amtrak speeds, a couple of feet of misalignment (again, look at Balt's image) could be pretty dangerous, especially with the high center of gravity of the cars.

Euclid, The truck in the photo does have damage to the heavy front bumper. You can see it is bent in at the bottom with verticle posts on the ends tilting out. That bumper is a heavy steel one not the typical thin ones that come on new trucks. I got tired of having drivers wreck the bumpers on our trucks and put heavy 'C' channel on instead back in the mid 80's. Didn't have anymore wrecked bumpers but they destroyed the pit railing instead. And the corner of a building.

Tree - truck was only empty as photographed - the sudden stop threw the contents ahead of the truck and over the other tracks.

Aha! Bit of speed involved there... Wasn't looking at the coal on the roadbed...
Given the damage to the cab of the truck, I wouldn't be surprised at serious injury or death for the driver.
The damage to the truck in the Kansas incident doesn't spell serious injury to the driver, especially if he was belted in. To his pocketbook, maybe, for leaving the scene of a property damage accident...

Actually, he wasn't hurt bad at all. Said his brakes failed coming down a hill - happened in Summerhill, PA.

In the second video of wanswheel's post above, the Amtrak power consist was AMK 153 and 152. If the power roams everywhere that was quite a coincidence sequential units were involved!

On Wednesday 903/16/2016) The Wichita Eagle (by Oliver Morrison) carried a rather lentghty article referencing the SW Chief's recent derailment and the envolvement of the 'grain feed truck', near Cimarron,Ks.
The article references a statement by NTSB member Earl Weener; stating that "...the' train derailed within 25 feet of the point of impact...", The article further stated; "...'investigators had found that the tracks had shifted 12 to 14 inches to the South..." ( infrormation from the video from the forward facing camera within the lead engine). Another statement from the article states;"... that the derailment had not occurred near a graded rail crossing, where a road is designed to to carry vehicles over the tracks..."
Additional details from the article indicate that the Cimarron Crossing Feeders,LLC. facility {a feed lot feeding approx 20,000 cattle} is adjacent to the location of the derailment, a sign for the entrance to the facility is visible from the area of the derailment, and the article further mentions Mr, Weener's coments "... that no report of any trucks crossing the tracks had been made to the local authorities or to the railroad,,,"[ie: BNSF]. It was further commented that an Official Report [from NTSB] of the accident could take approximated a year(?)
There was a statement included in the article referencing the speed of the train (@60 mph) but it was also mentioned that it took "... the Conductor had put the brakes on near the scene of the derailment, it took 18 seconds for the train to come to a complete stop and it had traveled 919 feet in that time..."
I am guessing that that was a reference to the Conductor pulling an emergency cord running within the train?
IIRC I thought the NTSB reported the locomotive engineer had applied the emergency brakes before the derailment.
samfp1943I am guessing that that was a reference to the Conductor pulling an emergency cord running within the train?
Conductor, engineer. Is there any difference? Based on the sheer volume of news reporters that don't seem to know the difference...
We do, of course, and the initial reports were that the engineer dumped the train when he saw the "track anomaly." The conductor, back on the train itself, would only be prompted to pull the brake if s/he knew something was wrong that the engineer hadn't otherwise recognized.
Looking at the area in Google Earth street view shows the feedlot is uphill from US 50 and the tracks. That makes me wonder if the truck was in the feedlot and the driver forgot to set the brakes and the truck ran away without the driver. Could the hill give the truck enough momentum to cross the road and impact the tracks. Just tossing out a possibility. A gap in the fence was mentioned but there was no indication whether it was existing or the truck made that.
More information from NTSB would be welcome.
Norm
Norm,
A runaway like that seems plausible. Suppose the truck ran down the hill, hit the railroad fill, ran up, jumped a bit, and landed about halfway across the track.
At some point, it was discovered, if not right when it happened. Then in a panic to drive it off the track, they discovered that the truck was hung up with its frame snagged on the track. Then what?
Call the tow truck and start a nice steady pull with a big winch. As the truck moved, so did the track. That would explain the ability to move the track with no particular damage to the truck. That is my guess.
There was no damge to the truck because there was no impact.
EuclidThere was no damge to the truck because there was no impact.
As noted by Bob Withorn, there is damage to the truck, specifically the front bumper.
And as I noted, with the usual profile of the ballast, etc, the ties and rails would be right about bumper level.
If I'm looking at the right feedlot, a runaway down county road 16 would have gone across Route 50 and over a crossing. No crossing has been mentioned as being involved, from what I recall.
I am not sure about the runaway part. It could have been a loss of control on the highway. I see the bent bumper sort of. I don't see it as being a particularly obvious irregularity in the photo. There is some distortion from the wide angle lens of the camera.
But even if the bumper is damaged, I don't believe it is from impact as the truck collided with the track. To get the energy to move the track at the speed of a collision would have done more damage. But to get the force at a slow, even pull of a winch, it would have been much easier to move the track without causing damage to the corresponding part of the truck.
As I mention the most likely way to get a firm connection between the truck and track would be the frame or axles. That would also have been possible with the bumper, but frame or axle on top of the track seems like a more likely way to get a solid lock on the rail. So I am betting that a tow truck moved the rail as it pulled on the snagged grain truck.
EuclidSo I am betting that a tow truck moved the rail as it pulled on the snagged grain truck.
1. Look at Balt's picture of the coal truck again. That truck dislodged two rails and moved the track structure on the center track. No tow truck involved.
2. Any incident involving a commercial tow vehicle removing a truck from the tracks would have also involved law enforcement.

Oh, I have no problem believing that the truck would be capable of moving the track with no tow truck. The picture of the coal truck, besides moving the track considerably, also shows massive damage to the truck.
I suppose the truck in this case could have moved the tracks by impacting them, and not suffered much damage. But it seems like that would require a perpendicular hit in order to direct the force into the track without producing a glancing manner of deflection. And yet that kind of oblique or glancing angle strike is what I would expect in the case of a vehicle losing control and leaving the roadway at speed.
I just sense that there is more to this story than what meets the eye. The way the NTSB is dancing around the truck involvement strikes me as odd. How long does it take to get to the truck driver and ask him what happened, assuming that the truck owner is cooperating as they say?
Maybe someone was in the habit of carefully driving over the tracks without the aid of a crossing to get access to fields when necessary. And maybe they were not so careful this time.
I see that there is a gravel road alonside of the track, quite close, on the side opposite of Hwy. 50. I have not heard of which road the truck may have approached from.

Ya know, I simply threw out the possibility of the truck rolling down the hill. Without more information from the NTSB there is no need to disect it.

I just threw out some possibilities too. Others may read them if they want to, and they may choose to respond. Here is an interesting video that seems to fit the general theme of this derailment, although this one was lucky:
