This is probably a situation where emergency braking isn't ideal. Lucky for the crew that the broken couplers weren't closer to them when they went into emergency.
interesting thought. I wonder what would have happened if he's just kept going and if there's any indicators that can point to the decision to just keep going to avoid what happened.
@@qweqqweq2090 Engineers are allowed to bring the locomotive to a safe distance in the event of a combustion. I'm guessing they weren't too worried given they distance had, and decided it was better to stop and inspect the remaining part of the train for any possible fires.
If the break in the rails is severe enough to cause a "bump" effect the couplers will break due to vertical pressure rather than horizontal then as they begin to slow the weight and momentum of the following cars cause the concertina effect that forces them off the tracks.
Looks like that creek bridge had tilted some, in the video you watch the lights kind of bounce after crossing the creek bridge when hitting land again. That seems to have caused something weak to break.
waterways really suck. they can cause the ground all around it to sink over time due to softening the soil under the immense weight and pressure. if there's any salt or pH imbalance the track can also rust and fall apart faster than normal. there's uncommon combinations that can occur in such cases where one slightly inferior issue with a track that would normally never be a problem combines with the accelerated decay and causes a derail.

Thanks again for clearing up that mystery. Rail On.
Due to poor maintenance and upkeep, a rail broke and caused the cars to derail on the bridge, which in turn caused it to tumble off the narrow bridge and into the creek, followed by the other cars.
Dammed You Tube ,all these disaster vids available watch one get a dozen others available to also watch , makes us more aware of how frequent these types of disasters really are and just how fast ones day could go horrifically wrong
The derailment was caused by inadequate track maintenance. Google "RAR1802" to see the full report. The investigation found that UP did not adequately maintain the crossties, which led to one of the rails being overstressed as it was lacking enough support from underneath. The rail broke because of that, as the train was passing over, and the train cars then derailed. A quote from the report: "None of the following were factors in this accident: (1) the mechanical condition of the train to include the train’s braking system, (2) the performance of the train crew, (3) cell phone use by the train crew, (4) alcohol or other drugs by the train crew, and (5) the emergency response."
I was just thinking about how Super 8 looked exactly like this. A minute and a half of train cars flying through the air, chasing after the protagonists.
Interesting thathe locomotives traveled over the rail problem but a lighter-weightank car derailed. How much weight did the locomotives impose on the rail? How much the tank cars?
Metal fatigue can cause the rails to break and most likely that happens over a period of time and is just a matter of when it would let go, rather than because of a specific weight on it. My grandpa was a railwayman and he talked about seeing frozen rails "snap like twigs" due to the extreme cold but others can be like a stress fracture in a bone. The crack starts out very insignificantly but gradually gets to the point where it can't support the weight it is meant to bear and unfortunately for train crews, rails can't start complaining about "pain" like we would do about early stage stress fractures in our bones. 😊 The other issue (and what I believe happened here) is that poor maintenance can see the track bed settle and cause the rails and ties to "bounce" slightly as trains pass over them. Over time if they don't see maintenance the bounce gets worse and can cause the rails to snap or simply come loose from the ties.
There are brakes on every carriage, right? The aft section detaching and derailing is less mass/momentum pushing the lead locomotive, but also less brakes, so would that have a significant impact on how fast it can slow down before the rail crossing?
I believe since there are brakes on every carriage, braking is about equally effective regardless of how many carriages are attached. The less mass should about cancel out the less brakes. (This is assuming all the carriages have a similar ratio of mass to braking power.)
(I have little knowledge about these operations, but this is about physics:) A long train must have around the same braking force distributed over its length (i.e. all carriages) in order to not derail due to distortions by the braking itself. Thus, for a brake system operated solely with compressed air, the brakes have to activate slowly, even in any emergency braking. Engineers at any position in the train can expedite this a little by opening additional valves. Also, goods carriages appear to have rather weak brakes to avoid sliding of the wheels. Passenger trains have more and better braking systems, especially multiple-units consists.
Each car has brakes, but the locomotive brakes are more effective than the freight car brakes. When the train separates, the brake line is broken and that reduces the air pressure in the train line, which triggers the triple valve on each railcar and locomotive to release air from each car's air reservoir into the brake cylinder on each car, applying the brakes. The air reservoir is split into two sections, the service portion is only used for a slight reduction in brake pipe pressure for normal train stopping, both the service and emergency portions are dumped into the brake cylinder if the drop in train line pressure is significant enough - indicating a break in the train line.
If you read the description, it says the speed for the rear of the train is from the locomotive at the rear, so there was also that locomotive's braking contributing to the rear of the train stopping.
Nate Halstead - Exactly those factors... Proper maintenance costs money... Money these corporate slugs don't want to spend thanks to added pressure from investors! Everyone's in it strictly for gain, and they pull out at the first sign of monetary inconvenience!
Especially on this specific line. There isn't enough train traffic across this line for then to profit by keeping this maintained unfortunately. There's a daily manifest train and an occasional unit train, but it's more or less a spur line
Listen, I'm here 7 months too Late, but according to many other reply sections, it's because UP Didn't look after their Ties when inspecting the Line. Therefore, one of the ties gave way, the Rail fell out of Place, and the Train Derailed. Not because the Bridge Gave Way.
Tankers are to dangerous with chemicals tho, I don't think tankers should be loaded with chemicals, what if the train derails that's to deadly and could kill a lot of people (this is my opinion its not based on the video)
So what other inland transport method do you suggest which is safer. By rail is by far the most efficient and safest IF everything is well maintained. I would say the trains should be shorter in length, limiting the size of potential accidents.
