This train blew the fuck out of its turbo and was probably running away, since it might have been sucking in the turbo's oil supply.
(runaway diesels happen when it gets too much or an unmetered amount of fuel and it revs out of control. a good chunk of the engines, such as the one in the vid, are total losses when it happens.)
I laughed really hard at the thread name.
Choo choo motherfucker
Must be the train from that Hey Arnold! episode

It hurts to watch a big expensive engine basically tear itself apart.
Looks like Doc Brown is at it again
From your description I was expecting the train to shoot down the tracks with enormous amounts of speed. Luckily for the crew and not my viewing experience that didn't happen.
The flames were pretty cool though I guess.
Holy fuck that screeching noise it made
Metal as fuck.

in the case of a run away i'm pretty sure there's a disconnect between the generator and the traction motors so that doesn't happen.
Runaways are the most scary things to happen to a diesel engine, especially with more modern turbo diesels in cars. It's near impossible to figure out how to kill unless you know exactly where the cutoffs are and most of the time they ain't obvious, never mind the issues with drive by wire systems which can completely fuck up fuel control and again cause a runaway.
I've seen someone have to resort to cutting the fuel line to stop theirs once because he couldn't find the air or fuel cut off valves, and the turbo would have attempted to eat anything you shoved over the intake.
the new series of Thomas the Tank Engine looks pretty damn metal.
It's like the train version of ghost rider
turbo makes me moist

Here's a runaway. Like I said in the op, they just rev out of control. This one had a locked injector. The engine was scrap. It was only killed by shoving something into the intake which, in the video below, might not even be enough (it begins sucking air through the exhaust):

Really old engines and far less likely to happen with modern diesels but still, super scary to have such a big piece of machinery out of control.

holy shit, that's a brand new truck. How did that happen? just shear shit luck?

Likely fuel controller as its electric in that model, would have got flooded and by the time they killed the ignition it'd be burning on oil. Kept going until it ran out and what you saw at the end was the radiator exploding.

Diesels are scary yo.
So was this the result of a mechanical malfunction or human error?

those guys in the second video look like the gnarliest motherfuckers ever. I'd be scared shitless to have that job, let alone hold on to a diesel going ham like that.
Looks like Thomas has his emo phase.
Or its the train to the gates of hell
I feel like instead of covering the intake, why not have a fire extinguisher handy in case of a runaway? I imagine if you spray co2 down the throat of an engine it cant combust anything, although I dont know if you can spray long enough for the engine to coast to a halt.

They're covering the intake, not the exhaust. It's the same idea.

Fixed, meant to say intake.
Yeah I had a friend who had his truck runaway on him, it's surprising how many diesel owners don't know about it. He went to go start it outside of the cab and it went off, causing him to panic and runaway himself haha. He called me because he had no clue what was going on and I could hear it in the background buzzing away. I told him to get a rag and shove it into the intake and he preceded to and it did stop but it had already ruined the engine by that point. We ended up just doing an engine swap and after pulling out the old engine and inspecting it it had spun the crank bearings, roasted the piston rings and scored most of the pistons and their cylinders.
It was a mess, and had he known what to do he could have saved the engine. Some cars are equipped with a valve that will stop the engine from sucking in air but on a lot of cars you have to shove a fire extinguisher in the intake to starve it of oxygen or grab a board or rag and stuff it in there kind of like this guy below.

He seemed kind of prepared for it to happen and while the turbo was destroyed he saved the engine.

Best things are to damage something non-vital if it means stopping it, replacing a turbo is easier and cheaper than a full engine rebuild or swap.
Something else you can do when a diesel does a runaway while you're actually moving is to put it into high gear and ride the brakes, put as much stress as you can on the engine and it'll eventually stall its self under the stress. Sure you might have a fucked flywheel, brakes or gearbox in the end but better than the engine going if you ask me.
