- A CSX train traveling on Buffalo's Belt line approaching CP-437 has a slight incident on the curve, derailing a few autoracks. Winter's Rigging comes in with there large equipment to clean up this mess. They work through the night hours and have it cleaned up before morning.

This is a perfect example of "string lining."
The flanges on the wheels "steer" the car for a lack of better description, but it is gravity that keeps the cars on top of the rail. This is a function of the ratio L/V, where L is the lateral force and V is the vertical force. Any time lateral force is larger than vertical force one of two things happen to end with a derailment.
If the slack is bunched up, ie compressed, like when working dynamic brake on a descending grade, if the forces are too high the car(s) will leave the track, punched out on the high side (outside) of a curve due to the phenomenon known as jack-knifing. Conversely, when in draft working power with slack stretched if L is greater than V the cars will be pulled off the inside of a curve, just like in this video.
You can replicate this at home. Find a few pieces of HO track if you can, or anything curved with a channel. Now cut a length of string two or three feet long. Guide the string with your thumb and forefinger down the middle of the track. You’ll find that the string will follow the rail’s track. Now repeat the experiment but after you reach the other end of the track with your string, put your other thumb on the end of the string. It will straighten out and bingo! String lining right before your eyes.
In the real world this could be due to too much trailing tonnage, a derailed car further back in the train or a UDE (Undesired Emergency Brake Application) that has anchored the end of the train. The track in the video looks to be in good shape so I would guess the inside rail didn’t turn over, making me think string lining came to call.
But there is a good lesson here. Train moving at slow speed. No indication of anything out of the ordinary. But, if you were standing there when these cars turned over you’d be a greasy spot under one of these cars. I’ve said it many times before. If you are in close proximity to any train that is underway, you are in mortal danger. Whether a motorist, hiker, pedestrian, train enthusiast or photographer, keep a minimum distance of 50 feet away. A train doesn’t have to be clipping along at high speed to be dangerous.
Treat trains like they were a rattlesnake.
To be honest, it looks like it could be that or a broken rail section. I've seen a similar wreck involving DOT-117 tank cars. The wreck was a cross between a stringline and a broken rail incident. The footage of this wreck looks very similar to the DOT-117 wreck, with the only exception being the car type.
Yes, it is a good idea to give a train wide berth, but what about roads that run parallel to the tracks?
@@thomaskerley1388 I never knew what those were for. I guess it's for maintenance of signals or points.

Thanks for the contact. I've wondered if anyone was reading this stuff. And you have a good point, but it isn't a typical scenario of grave importance.
The carriers usually own or have a long term lease on the land on which the tracks are laid and on both sides, as a rule. This dates back to the Pacific Railway Acts signed in to law by president Lincoln in 1862. During construction, the UP and the CP were granted one square mile (640 acres) every mile alternating side to side. It was a huge incentive.
As a result, in most instances the rails are more than 50' distance from the public roadway. Those roads that are right next to the track are usually company property and it is illegal to trespass on them. I am sure there are exceptions.
As for those areas where the roadway actually has tracks running down the middle of them, all you can do is try to stay as distant as possible. They too travel at low speed, but we know cars can derail at any time, anywhere and at any speed, and by numerous causes of derailments, like too much tonnage, L/V ratio exceeded, failed draft gear, broken rail, defect in the roadbed, thin flange, collision with a roadway vehicle, cradle effect, broken rail or excessive speed.
Ultimately the responsibility lies with the individual to exercise a little common sense. Trains don’t hunt people down. People put themselves in harm’s way. Thanks for the opportunity to bang on the safety drum yet again.
Stay safe.

Rerailing is an art form.
high center empty cars. Horseshoecurve sends its regards XD
HAHAHAHAHA! They just can't keep 'em on the track, can they? 😆
Hey, they was tired and wanted to lay down!😂
Fell over at 0:20
What do they do with derailed cars that are so damaged they can't get them back on the tracks?
These ones they were able to rerail and push into the yard for bad order. Ones that are really destroyed usually get picked up and put on flat cars or cut up for scrap.
A derailment can cause a cascade of consequences, especially in a heavily traveled freight corridor. So the operators and carriers aren’t too concerned about the loss of a few cars. So most of the time they bring in big CAT D-9’s and push derailed cars out of the way so track panels (pre-built ready to install track, just like a piece of model railroad track) can be quickly laid and the line reopened asap.
Cars that are totaled, as result of the derailment or heavy handed treatment from those big bulldozers, meet up with a guy with a torch. Once in pieces a work train comes along with gondolas and a burro crane with an electromagnet and the chunks are loaded into the gondolas and head for the scrap yard. But freight cars hold up fairly well. As long as the frame isn’t bent they are relatively easily salvaged and returned to service in most cases.
Terrain plays a part as well. Where inaccessible the cars are emptied and left to rust.
Good question. Thanks for asking.
Oh boy, did they have cars in them?
As fas as I know these were empties.
Cool Video!
That all 2 B C falls
Camera run out if memory after 3:07?
Safety was not worried about here.
Bruh how did it tipped over like that? (It was like alright done, no more lol -falls over-
More like a video of a TV showing a video of somebody's model train falling over.
Sounded like a broken rail
Exactly !!
I belive thats the banging sound heard b4 derailment. .
Hopefully they had electric cars on there
I wonder what caused this crash.
Looks suspiciously like a stringline derailment.
Hi. I just posted a comment that will answer tour question.
Bonk!
How did the train derailed I have is not something very important
String line derailment
This is some shit you would see on a layout 😂
You work in that yard haha?
I work at the building adjacent to the tracks.
Woah another derailment dam
Pet peeves. People who take video of a video playing on a monitor. Just transfer the footage onto a USB Flash Drive.
Maybe it was recorded in .avi format and YT takes to long to upload that format. Maybe the uploader did not have a video editor.
