Check out this very short video of a guy chasing a train at speed with a hopper car having issues.

Pneumatic brake failure, by the looks of it. I’ve seen this before in person while chasing and was able to get the train stopped. What happened was that the piston that applies the brakes was stuck shut so the brakes were still applied even though the air had been let off. Other possible (but less likely) culprit is that the manual brake wheel had been applied and never taken off.
This causes wheels to flat-spot, which is why sometimes you’ll hear a car make a loud repetitive “tha-THUMP” noise as the flat spots hit the rails. Something this bad though could cause a derail, so they would set the car on a siding to either be towed away or repaired in place.

The one I caught I stayed with until they stopped it and stuck around to watch them try and fix it. The amount of slag from where the wheels had ground along the rails and gathered up behind the wheel was incredible. When they stopped the train and slacked it off, the wheels actually rolled back onto the slag and the conductor didn’t want to move the train again for fear of it coming down off the slag and derailing.
After a few hours I ended up leaving because they had a welder come out and knock the slag off, and upon request he gave me a piece “so I could dispose of it for him”

This was as good of a picture as I could get at the time of the wheel sitting on the slag.
While we were waiting for the welder, another train was about to pass by but they stopped to get out and look. The engineer, who was apparently a veteran for NS, commended me saying that I could have prevented a derailment that night, said that I could probably get a job with NS if I told them that.

Damn impressive piece of memorabilia!
So did the welder just take a blowtorch to the rail or was it a more involved procedure?

Whenever you're cutting rail to replace a chunk, you use a big abrassive saw blade. Think of those little black things for dremels, but way bigger. You torch cut to get rail to an approximate size, but use the saw for finishing to final size.

While what you say is true… this one looks like a truck failure as the side frame is on the ground while the axle is still on the rail. You can see how low the knuckle is on the damaged car.

They didn’t replace the rail, I think he literally just cut it off the head of the rail. Honestly I don’t remember as it’s been several years
