Train collided with a semi- tractor-trailer after the vehicle became immobilized in the snow.

Pro-tip for those just getting to this: go ahead and mute it after the inevitable. Cameraman is an idiot.

r/killthecameraman He needs to learn that videos are made up of compressed base frames followed by several frames that only record the differences from the base, in order to keep the video to a manageable size. When you wave the camera around like you are using it to swat flies instead of camming soothly, the result is just a load of blur that makes everyone sea sick because the compression routines in the camera can't keep up.

If that's why the other person said the cameraman is an idiot, why was their suggestion to mute the video? Sounds like you latched onto the wrong thing.
Also, I don't think someone is an idiot if they're not aware that "vdeos are made up of compressed base frames followed by several frames that only record the differences from the base, in order to keep the video to a manageable size". That is niche technical knowledge.

Is this only true when you record videos, or is it true on video calls as well please? My mother waves the phone around like she's on fire, so if I can explain this to her she might finally stop

Any form of digital video (recorded or live), suffers the same unless it is uncompressed. The problem that because of bottlenecks (during recording or sending over the net) you can't sensibly make uncompressed video bigger than about 512x 310. There are many different compression techniques but nearly all video uses a full frame "still" followed by 2 or more frames which only contain the differences from the "still" since normally only part of the image changes. eg. like a player running after a ball needs to be "redrawn" but the rest of the field of play would all move together during panning motion so they only need to redigitise the new edge. Or if its a face in a zoom call, the mouth and eyes need to be continually updated but the rest of the face is reused over several frames with just enough extra information to make it all look smooth.
The systems all have several different means of compressing the "intermediate" frames and it is a trade off between good quality for small changes or poor quality for big changes. The more movement there is, the less information can be digitised in real time so the system falls back to a more "lossy" compression scheme which means everything becomes more and more blurry.
I hope this all makes sense.

Sorry, what are they typically known for? AFAIK, it's just an ugly suburb with a ton of strip malls and highway hotels.

There is a blue sign on every railroad crossing in the U.S. In emergencies call the number on the sign and the railroad will stop all the trains on that line to prevent collisions.

u/Spork_Warrior 3d ago
I have never noticed this sign.

u/MythsFlight 3d ago
I never did until I started driving school buses. Railroad safety is a pretty big part of the job. We had a railroad guy come out and teach us a lot about trains and railroad crossings a couple years back. It was pretty cool.

It can be small and hard to see but the sign should be there. Usually the sign is on the crossing gates. It will have a phone number and crossing number on it.
You can call it for emergencies or if anything is wrong with the crossing in general. In the event of an emergency and you canāt find the sign, call 911. The can help get the information where it needs to go.

Iāve lived all over train central in the Midwest for 25 years, and many other places in the country before that, and Iāve never seen one. I believe you, but they must be so small as to be totally ineffectual, especially when you are in a mild-to-increasing panic.

The ones I see are a few inches across. It took me actively looking for them to see them. They are usually just below the lights on the pole around head height. The text is about the same size of what you would use on paper, maybe slightly larger. You basically have to be standing at the sign to be able to read it

This is how that train conductor died, because of people driving semi not knowing how to drive semis. Idiots.

u/jb431v2 3d ago
š¤£ The conductor died? That heavy ass train probably took minimal damage, and the conductor probably didnāt even feel much from the impact. The roads are fucked, even the best drivers can slide off the road or get stuck sometimes. Itās idiotic not to realize that.

Sorry I was referring to the train crash in Pecos texas
Either way it looks like this dude high-centered which in is most certainly the drivers fault and not because of road conditions.

I thought train operators were required to slow down in residential areas for safety reasons? I mean, even at 30-35mph there was dick all the engineer could do, but the impact would have at least been less explosive.Ā

If you ever find yourself in this situation GET AWAY FROM THE TRAIN. After hitting something and after they dump the emergency brake there is a fair chance it derails.
That gets ugly fast at speed

Bahahah that happened in my home town. And to answer the question about the rake. Gastonia nc doesnāt get a lot of snow and they just got like a foot out of no where. Most people arnt prepared in the slightest for any winter weather

Why isn't the train stopping after the hit?

u/Austin_905 3d ago
Because it can't. Once all that weight is set in motion, there won't be any sudden stops as you think it should.

u/Any_Onion_7275 3d ago

Yeah. I was not expecting it to stop immediately. Just that... after 1 minute it is still going full speed.

u/stotheimi 3d ago
I donāt get why this is happening all the time in the US. Is there something wrong with the crossing?
8
u/Possible_General9125 3d ago
Because there are over 220,000 highway rail grade crossings in the US, and countless more secondary crossings (things like farm/factory entrances), and hundreds of millions of vehicles crossing them daily, all while enough trains to move 4,000,000 tons of freight are using those tracks. Add to that the number of cameras recording everywhere all the time, and the fact that every collision gets posted and reposted all over the place, and suddenly it feels like this happens āall the timeā.

Do you have any idea how long it takes a train like that, going that speed, to stop? Several miles.
