That was close. The railfaner says the train saw the truck in time due having about 1 mile of view ahead the rail cross; but that's enough to stop one of those? It seems more likely it was advised on advance and was already slowing when reached that straight sector of rail.

And the comments section of the video is full of people talking about if the trucker had to do this or that.... I just wondered why not to raise rear suspension. Is it common on that model of truck to have it without rear air suspension?

@Some newbie driver

it has rear suspension (that truck model yes) but it is already RAISED by default.

The only thing you can do with that air suspension is to DEFLATE the air bags so that the truck lowers.

So no, you can't raise more than the default setting which he was already at since the beginning. You can only deflate not inflate more.

Depend a lot on the load behind, the shorter and lighter the train is, the faster it will stop

@gt379 thanks for the answer, but it opened more doubts even. Seems a lot weird to me that the suspension it's at maximum height at ride level; when one of the big benefits of those suspensions is that, by allowing to be raised over normal ride level, scenarios like this could be easily, rapidly and safely avoided. Specially when the truck is being use to haul very low floor trailers (would it had been hauling regular trailers, I suppose such a "feature" would be mostly pointless) Seems to cheap out the engineering of the suspension IMHO to allow only to go lower. But just my point of view "from outside".

@rookie_one yeah, of course, it's always weight after all. But I'm so used to those massive and infinitely long trains you had on there that "just" 1 mile to stop seems very low distance. In the same video, on a very nearby railway, another train passed and really it would had been impressing to stop it at such speed on 1 mile when the train could easily be 1/3 of that distance in length or more. The one that stopped seems to have 3 locomotives, so if not a heavy one, just by miracle that it was going to take some load because it was meant for sure to be a fat one.

Locking the diffs could help as well, but all trucks don't have that option. The best way to prevent this kind of thing is better route planning, crossing a raised point slowly, and raising the trailer ride height if possible.

With a hydraulic lowboy you can raise the deck, but this might be a mechanical.

It's clearly seen several time how both rear wheels burn when trying to push, so they already tried diffs. That of course isn't going to help so much because it was not a problem of the tractor loosing traction due bad axle contact. it was the trailer that landed on ground and once there the truck could do nothing by itself.

And seemed the gooseneck is hydraulic too, because at some point they were trying to connect the battery of a pick-up on a compartment in the trailer nose; so probably trying to start an engine on the trailer that powers the hydraulics.

So, they really had all the bad cards in their hand that day. At least, they used all the remaining luck to avoid being rammed by the train.
