High-centered vs truck frame not clearing crossing. Is there a real difference or is this just some jargon?
charlie hebdo High-centered vs truck frame not clearing crossing. Is there a real difference or is this just some jargon?
I think certain people are dancing with semantics in the absence of knowledge again.
"High-centering" can mean either that the frame has come in contact and the wheels cannot push it further, or that the frame is holding part or all of the drive wheels clear of the surface.
When I see 'undercarriage' I think of tag axle before I think frame contact on that type of truck. Again, it remains to be seen whether that particular truck had a frame section between the steers and the tag that would have physically come in contact. Frankly I can see that with a beer truck chassis, but not a heavy dump truck.
Wait for the (inevitable) accident reconstruction videos.

I have not seen a definition of clearance. High-Center implies physical contact whereas improper clearance could just be a few 1/10s of an inch below the legal limit.
It looks like the lawyers threw in as much as possible.

BackshopOn a truck like the dump truck in question with several axles, it isn't possible.
Do we know with any certitude what this dump truck looked like? Around here they are all tractor trailer rigs.
The other consequence is that the vehicle is inspected by police and found to be out of compliance with the ground clearance laws; when no actual frame-to-road contact has occurred because the vehicle has not yet passed over any ground clearance conditions capable of being struck by the out of compliance vehicle.
A not likely speculation. What if the truck could not carry a full load due to delivery locations? Then truck was loaded in rear of truck bed --- or the steep approach to the tracks caused the load to shift to the rear. If so what could that to the balance of truck ? tail heavy ?
Euclid I think the main question pertains to what is meant by the item in the list of legal charges against the truck driver released by BNSF and Amtrak. Their statement appears to be poorly written, or contains incorrect information. This is that statement: “Operating the Dump truck through the railroad crossing without sufficient undercarriage clearance necessary to prevent the undercarriage of the vehicle from contacting the railroad crossing in violation of § 304.035.4 RSMo;” All this says it that the driver was operating a truck with insufficient ground clearance. It does not say that the truck did or did not high center. It also does not say that the truck contacted the crossing due to having insufficient ground clearance. However: The statement by BNSF and Amtrak does say the insufficient ground clearance was such that the truck frame would have contacted the crossing if it passed “through” the crossing. If that means the truck passing entirely through the crossing: We know that the truck had to have contacted the crossing with the lowest part of its underframe. This is the only conclusion that can be confirmed by the BNSF/Amtrak statement. However, even that is dependent on whether the truck passed entirely through the crossing. And that would have been impossible because the truck was struck while on the crossing and was immediately thrown off of the crossing by the impact. Therefore, the truck could not have passed completely “through the crossing.” Based on these details, I suspect that BNSF and Amtrak have no evidence that the truck contacted the crossing. Any direct evidence on the crossing would be in the form of damage, but it may have been as minor as a scratch that was indistinguishable from any other signs of general wear and tear on the crossing from normal use. So, I believe the most plausible explanation for the language in the statement by BNF and Amtrak is that they only measured some features on the wrecked truck and determined that it had insufficient ground clearance. So the only crime would have been operating a truck with insufficient ground clearance. I also think it is highly probable that the measurements were taken hastily with little care for accurate confirmation, and thus could have been easily mistaken in the dimensions they determined. In any case, the statement does not provide any evidence of there actually having been insufficient ground clearance. So I conclude the following regarding the charge of operating a truck with insufficient ground clearance: If there was insufficient ground clearance, it did not play any part in this collision. I see no evidence for there having been insufficient ground clearance. Overall, I see no evidence for the charge of driving a truck with insufficient ground clearance.

I had to read this a couple times to get the entire effect. I kept expecting a quote from Alice in Wonderland to be thrown in for good measure, just to see if anybody caught it. I can't conclude anything because I wasn't there. Neither were you. What I can see, is that your theory has some holes in it. Suppose, that the locomotive had a camera on it. Now suppose that camera recorded video showing the truck not having enough clearance to get through the crossing and that the truck then got hit by the train. Suppose that information hasn't been shared yet. Suppose that leaves your conclusion full of holes.

The post by Euclid exposes the hazards in deductive reasoning as well as semantic quibbling. Far too many conclusions on far too little evidence yields abmaybe at best, a big zero at worst.
Wow! You just wrote 12 paragraphs to explain your previous 11 paragraph post. And yet, it still looks like a lot of conjecture on your part as you try to make the known elements of this event mean what you want them to mean in order to prove the conclusoon you jumped to. You honestly want us to believe that someone measured the frame of twisted wreck to ascertain that the truck frame was too low to the track!

Here are photos of both a tri and a quad axle dump truck. Would anyone care to explain how the frame could come anywhere near the ground? The truck in the accident would've been very similar to one or the other.

As I understand it, the center axles shown raised on the photos (pusher axles?) are unpowered. If those axles were lowered and the truck encountered a short hump, like a raised grade crossing, could those axles cause the powered axles to lose contract with the surface? Or are there elements designed into the suspension that would allow them to give enough to keep the powered axles on the ground?
And out of curiosity, do those extra axles have some sort of steering capability, or do they just get dragged across the surface when the truck turns?
No steering capability. That's why they are normally raised during sharp turns. Less sideways scrub and friction on the tires. They have airbag suspension so they have quite a bit of vertical travel. Remember, dump trucks are designed to drive in gravel pits, landfills, etc.

Euclid BNSF/AMTRAK quote from legal filing: “Operating the Dump truck through the railroad crossing without sufficient undercarriage clearance necessary to prevent the undercarriage of the vehicle from contacting the railroad crossing in violation of § 304.035.4 RSMo;” Actually, I find that the issue was not that the truck was driven on the roads while it had insufficient ground clearance according to a law. Apparently the issue was only that the truck was driven through the crossing where the collision occurred while the truck had insufficient ground clearance for the truck to pass through the crossing without contacted it. So how could that have happened with a truck such as the one in this collision, which appears to have maybe a couple feet of ground clearance? Of course, I will not conclude whether the truck frame contacted the crossing because I was not a witness to that. But I must conclude that the language of the blue paragraph has to mean that the truck frame contacted the crossing.

Most of the truck was still on the NW track.The loco shows only damage on the NW side. Where on the truck the loco hit the truck may say a lot? "IF" the idler wheel were down could the steering tires not be contacting the road where the grade falls off just beyond end of ties? Not likely but before crash maybe truck was yawing to the right?
No, they wouldn't lift the steering axle off the ground.
