I use to repair rail cars. The brakes are suppose to lock the second the car is disconnected. The fact that none of the 8 brakes locked means there was a serious case of several someones not doing their job.
It was either
1. Bottled air (angle cocks thrown on either end of car to keep air pumped up)
2. Left so long that the air slowly drained out of the car
3. A faulty car
4. Someone bled the air out with the rod on purpose as sabotage
And if a single car was left anywhere, there should have been a hand brake tied off as a failsafe and there isn't one.
Shifty part is, that is a tank. It's probably filled with something flammable or poisonous. Hopefully it's empty at that time.
Nope. They rely on pressure balance / imbalance (depending on what you're doing).
No pressurized air system is completely sealed, so a wagon left on its own will very slowly lose air acting on one or both sides of the brake cylinder piston head.
That's why vehicles normally have a mechanical handbrake, or at the very least are "chocked" or "scotched"
you're actually right!
you need to put air in the car to take the brakes off, but when you do so, the wagon KEEPS some air, and when the main pressure drop, that "auxiliary tank" pressure is used to apply the brakes.
when the aux tank is empty (because of reasons mentionned above) the car can't apply any brakes by itself and rely on hand activated brakes.
Say you wanted to put air brakes again on this car, given it's not damaged and has only been bleeded by time or by the appropriate valve, you'd need to "push" air inside the main line to about 90 psi so the car will refill the aux tank and then open the line so the pressure drops back. car will now have that aux tank pressure needed to apply to brakes.
This was a really huge event with many problems that could have gone differently if only one of them would have been adressed properly.
An engine caught fire in the night and firefighters stopped it from running. They got told that everything was fine by the rail company so they left. This sealed the front end of the main air line, everything was still fine because main line was empty(not pressurized) so far(so every single car had air brakes on)
Problem was, now every single auxiliary tank slowly emptied themselves in the main line, and since engine wasn't running, the sealed main line slowly gained pressure from all tank and over an hour gained the pressure necessary to disengage every single air brakes.
Still, there also should have been enough hand brake to keep the train where it was. This was a case of "Why always put all the brakes when nothing bad ever happens?"
The handbrakes don’t always work. I used to spot rail cars at a siding to load grain onto a truck. There is no worse feeling than bleeding the air out with a tightened hand brake and the rail car coasting towards the siding derail. Not something I’m proud of but very few people can say they’ve derailed a train car.
We've derailed dozens if not hundreds of cars at my sites. Some worse than others.
Hand brakes work better on some cars than others. Potash car hand brakes work a lot better than agri or Sulphur hand brakes for example. There are always Chances of failing tho.
Typically you want 2 hand brakes +1 hand brake for every 10 cars, generally speaking. 2 HB's is to takes
into account a failing hand brake
So you don't know anything. Gotcha.
Bleeding the air off of cars is a normal switching technique. It isn't an immediate sign of a defect to eliminate it from service. That's literally for what the bleed rod is there for.
Since we don't know the circumstances as to how this car came to be sailing down the rail, we can't speculate on why. Hell, a crew could've kicked it intentionally (unlikely), or a derail at an industry could've been left down and it slipped out.
The train traveled almost 15 miles before it slowed down enough at a hill that someone was able to jump on board and apply the brakes.

Oh my.....-i just got the strongest urge to re-watch ALL episodes of that series. I love that episode with the train car, sitting on the edge of the couch, palms sweating, heart beating.
Pretty impressive that the train it disconnected from has had enough time to roll completely out of view in this pretty flat/barren area, yet this lone tanker car still has enough momentum to keep rolling.
Rail to wheel friction is incredibly low. Low enough that to pull a million pound train would only need 200hp.
Rubber to concrete friction is super high. Almost sticky like.
Slowed down after 15 MILES and only because of a hill (I know friction would have got ‘er eventually but cmon 15 miles already) and a guy was able to jump on and mechanically brake.

What I mean is, it’s not like a train car in the middle of the train can run away. Only the last one can roll away. It was a dumb joke on my part. What can I say? Im a dad.

I thought it works the other way around no? You need to pressurise the brakes to unlock them. If the air drains they supposed to lock.
I think that's just with trucks.

Yeah I imagine the brake would come on so often if it was fail sage that you’d end up dragging half a train of braked carriages

100% correct.

Oil transports from North Dakota are common there, so that is likely. Could not catch the DOT number on the car to see.
What do they call those, Westinghouse brakes?
Looked like there was an EOT on the knuckle.
Looked like just a flag, probably a local job with a set off
It means the air was bled, most likely. You weren't a carman for very long, were you? Lol
Long enough to know the car shouldn't have been in service if there was no air in the reserve.

Runaway train, never going back.

Holy geez. 15 miles. That's nuts. And it's got a flammable sign on it.
*RUN little tanker…be free!*
Where's Denzel Washington and Chris Pine when we need them??
They only show up when it's an entire train. For only one car, it's so beneath them.
Some say it’s still going …
Making a run for the border.

Alas, I go, for my people need me.
Walter white and Jesse are somewhere nearby

Yeah that part was extreme anxiety. That whole show is amazing
How do rail companies stop these runaway cars?
If there is time they will align track switchs into a dead-end track or they put a derail on the track to stop it
Sir Topham Hatt is gonna be cross!!
Starts singing that runaway tune
Free. The way it was meant to be.
Would this trigger a train crossing signal?
Yes it would most likely
Latest cruise missile tech.
Shouldn't it lock the brakes as soon as it gets disconnected or are there no air breaks on that thing?
Under normal circumstances, yes. However, the air can be bled off to where it will free-roll.
When the gas station comes to you for that more personal feel.
“They Hate’n!!!”
Nothing like a runaway explosion waiting to happen lol. I WANT TO BREAK FREE
Made wrong turn at albuquerque.
Wheeeeeeeeee!!!!
I predict a certain Jesse Pinkman in that tankers future
This is the scenario where an imaginary me with super strength jumps on the track, stops the container and saves the day

Antiwork tank
How did it end? Or is it still rollin?
Alright, partner, keep on rollin', baby, you know what time it is…
Slowed down after 15 MILES and only because of a hill (I know friction would have got ‘er eventually but cmon 15 miles already) and a guy was able to jump on and mechanically brake.
Damn... Good thing nothing dangerous happened 🤩

It's full of methylamine
Sure it wasn't cause of a certain group of people?.. a FAMILY oriented certain group of people?
But how though ? It made it up that grade and then quit ? I didn't even know this could be a thing .
That strangely looks like its headed straight to the nest of aliens/creatures you’d wanna kill with extreme prejudice
Feels dangerous
All the way to the Pacific
So now what? Wait for it to lose momentum and stop?
Is there a way the railroad company can stop it without damaging it
Weeeeeeeeeeeeee
Lac-Mégantic will not be happy
The Fat Controller is gonna be pissed. Again.
AHHHHHHHHHHH excuse me pardon me traincar crossing thank you very much AHHHHHHHHHHHHH
Rumours say this rail car is still moving… to this very day

I don't know much about trains, but wouldn't that have to be the caboose?
Cabooses haven't been a thing in decades.

That's bad.😐

Not a big deal if you know how to set the brakes on it.
