@@worlds_okayest_pilot_421 stating a fact like that in this context isnt really a "know it all" move. And it was just a little phonetic slip up, it happens. Im sure he usually spells "brakes" correctly.
You have probably learned about this in the meantime ... train brakes are kept open by pressurized air. As soon as the air hose breaks anywhere on the train, the air will get out and every car will automatically engage the brakes. The crew then has to walk along the train and find the damaged hose to repair it.
Probably a hose blew. It's the most common cause. That's why they carry spare parts and tools. Quick repairs are time savers. Or there could have been something happened a few miles in front and had to get stopped in a hurry.
Excellent video!! Whenever I hear a train goes into the emergency it makes that irritating squeaky noise! But it's rare when train goes into emergency!
FYI when a train goes into emergency automatically, it comes to a quick stop. The brakes cannot be released and the train's brake pipe recharged until the cause, a broken air hose, uncoupling, a derailment or collision is inspected and corrected. Then the train line is recharged and the train can then proceed. The emergency brake can be applied manually by either the Engineer or the Conductor as well.
I enjoyed the video. For an emergency stop it was relatively smooth. Back in 1972 I was on Amtraks train the Super Chief. We were outside Pasadena, CA , going about 90 mph when we hit a truck at a grade crossing. The engineer put the train brakes into emergency. The car I was in was near the end of the train that was 20 cars long. I tell you it was a very violent stop. I felt those brakes go on hard and there was a tremendous bang and jolt as the coupler slack ran in.Was very exciting!!!!
Most likely a broken air hose, or possibly PTC activation if the train was speeding. Or a PTC malfunction causing an unexpected e-brake application. It happens from time to time.
@@JimLiElevators Air hoses are what connect the train's brake lines between the cars. Air compressors in the locomotive provide air pressure that charges the "train line" in the entire train, and also pressurize three reservoirs on each car. Air pressure in the train line keeps the brakes released. When the air pressure in the train [air] line is reduced by a certain number of pounds per square inch (by the engineer making a reduction on his brake valve), the brake reservoir on each car releases the same amount of air pressure into the brake cylinder and applies the brakes. When the engineer makes an emergency application of the brakes, instead of the usual 10-20psi "service reduction", the entire 70-90psi (depending on whether it is freight or passenger) is released. A device called A "triple valve" on each car senses any reduction in train line pressure, and releases that pressure to the atmosphere while permitting an equal amount of air into the brake cylinder. When there is an emergency application, ALL the train line's air is instantly released to the atmosphere. Under normal circumstances, this is the result of the engineer throwing the train into emergency, but if one of the two air hoses between two cars breaks/ruptures, it will also cause an emergency application of the brakes since all of the train line's air pressure is suddenly released. This is a safety device; if a coupler breaks and the train physically separates, the instant the air hoses separate both halves of the train will go into emergency. When an air hose breaks, the conductor has to walk the entire length of the train until he finds the broken air hose, at which time he can replace it. Every locomotive carries several spare air hoses for this reason.
@@JimLiElevators it is a hose that runs from car to car that support the brakes.when the trains need to slow down it will activate some brakes.but in this case the E-brake activated all brakes.The cause was as others said,a PTC error,or a air hose hanging too low.
@@JimLiElevators train brakes need air pressure to remain off. That air is carried from car to car in an air hose. If the hose breaks then there’s no not air pressure and all the brakes get applied because of the lack of air pressure.
They can happen for many reasons. Popped air hose, cars accidentally uncoupling (which would pop the air hose), sensitive brake systems, train brake applied too quickly. There’s so many different reasons
I'm a retired engineer with the UPRR and sometimes when u set an air appl u might have a car with a 'hairtrigger' brake valve (what we call a dynamiter) which puts u in emergancy.....finding that car can be a pain!
Hey question. I wanted to join the railroad but I was worried from what I saw not into able to really have a social life. Am I able to still visit my friends often while being an engineer or will I rarely get to see them?
I'll never forget that sound. In our small town, we have a festival every year, celebrating the local agricultural product. There was also a rather high speed section of UP track that ran parallel to the highway on the other side of the city park. One of the developmentally handicapped residents in the home that bordered the park had somehow gotten away from the facility and disappeared into the crowd at the festival. She had made her way to the train tracks, as she loved to wave at the trains as they went by. Most of the UP Engineers knew of her and gave her a blast of the air horns as she waved to them. I remember this time he laid on the horns, a long solid note about a mile out. People began to watch the train. And there she was. Right dead center between the rails, waiving at the train. About a half mile out, he applied emergency braking, but it was too late. It was a heavy consist of Canadian wheat, headed for the mills to the south...
I was on Amtrak once and we had hit a bunch of deer! the 203 OLS was leading off which is kinda ironic, anyways, we got thrown into emergency and man It was a hard stop.
Also fun fact i live near Sugar Land. And trains Mainly UP tend to just stop for no apparent, reason but it seems like the air hose broke somewhere on the train.
Recently I saw a train go into emergency braking when an air hose coupling drooped too low between the cars. When it got to a certain road crossing, and the gap the normally is between the tracks is suddently replaced by a pavement section, it smacked the droopy coupling and ripped it apart. This stuff happens every so often. Don't get too excited by it.
Well seeing that no accident occured it could have either a coupler broke, an air hose disconnected.... Or PTC caused the emergency stop. Seeing that the train already passed a signal at a high speed a PTC caused emergency stop is possible. PTC sometimes acts up
I recently caught Norfolk Southern 350 go into emergency while railfanning Raleigh on Veterans Day, must have not prepared a switch to go to track 2 which is supposed to do that. There was no damages when I chased it east and didn't record there, the reason I thought the train went to emergency was I thought there were multiple wheel bearing issues that might derail the train, but it wasn't. It moved like a minute ago and it finished crossing through.
Air hose , valve bodies , accidental , etd problems . So many issues . Get out and start walking . This is my route to Temple Tx or back to Galveston Tx
Ive only been recording trains since about august and ive seen one, Im now suprised how early into my recording of trains career i got to see a train go into emergency,
Any number of things could've caused them to go into emergency stop. A knuckle arm could snap causing one of the cars to uncouple the trains onboard computer could've detected a hydraulic leak coolant problems in the engine it could've been a number of any item that could cause an emergency stop
The same thing happened in malaysia too, after getting off an ktmb class 93 at senawang station, i went up the stairs as the train departed but then suddenly heard a loud hiss that scared the crap outta me, and the next second i saw the train stop, the train took a while to get moving again
Yeah - the train brake hose (charged at 90 psi) uncoupled between 2 cars - the hissing sound - and the train brake is automatically applied full hard! Train probably did not hit anything/anybody!
Imagine if the railroad crossings were so far apart from each other when the freight train goes into emergency stop. There would be a major detour if that happened.
So good. I like this video very much because it's very interesting. Thank you. You are very confident. Very interesting experience. Always beautiful and beautiful. I like too.,.,’

That loud hiss was an air line breaking when that happens each car is designed to automatically apply breaks including the engines.
Such a know-it-all, yet doesn’t know the difference between “brakes” and “breaks”

Or autocorrect error
@@ryans413 That loud air hisssing was actually the air being dumped, applying the brakes in full emergency

On freights Emergency braking is an experience. especially if you pull a knuckle
Most likely a broken air hose, or possibly PTC activation if the train was speeding. Or a PTC malfunction causing an unexpected e-brake application. It happens from time to time.
You don’t mind telling me what an air hose is? Someone was asking me about that and I don’t know what it is at all to be honest.

We call it a kicker in Canada
We call them kickers at our railroad. Only had one so far

it could be anything from a signal suddenly changing to red and you have to just dump the brakes
I know nothing about signals, but the brakes can apply if the signal changes after the train passes it? How does that work?

Sounded like a air hose came loose.

Nice catch of BNSF 7678, the leader. The H2 ES44DC is becoming an increasingly rare sight on BNSF
3:50 more than a second lol.

Don't get too excited by it.
Its was actually airhose breaking or coming loose
If the air hose was broken the emergency brakes would be one and that will stop the train

Broken coupler? I didn't see any railcars separate at all after driving through the entire train.
@@JimLiElevators Oh... Well then it was most probably a PTC related emergency stop.
Sometimes the uncoupled half still has enough momentum to slam into the first half.....scariest thing ever
Probably not a PTC issue, PTC is usually a penalty application at a service rate.

I wonder what he had to Pull the emergency brake
I thought the train cars separated
No, I didn’t see any railcars separated.
That train stopped pretty fast. I'm seeing comments talk about PTC. Idk much about trains but what is a PTC?
PTC is positive train control.
I had a card that sounded like that when I put on the brakes lol
Right time, right place
Air hose , valve bodies , accidental , etd problems . So many issues . Get out and start walking . This is my route to Temple Tx or back to Galveston Tx
You were on this train?
I just notice railfan on the left corner of your screen on the next crossing, by the the stop sign
What timestamp was it? I didn't see any.
@@JimLiElevators 1:06
I had this happen before with 4x3x0 mixed freight train. Mostly the defect went off
Most likely a broken air hose somewhere throws it into Emergency or PTC
First time seeing a train go into emergency I take it? Lol
Glad everyone safe
I'm surprised he was going that fast. Sugarland has a dense population
An air hose probably bursted. Its really common to happen.
Cool video :) and thank god no one was injured (including the train’s crew)
That’s strange,I haven’t seen that happen before when I was in sugar land, that’s super weird
I’ve never seen that coming. But I’m glad everything is okay.
I always love how people's imaginations run wild when something odd happens.
Once a freight train hit a car when I was railfanning and it went into emergency
I saw heard that exact sound on a csx recently and the train also went into a immediate stop
Ive only been recording trains since about august and ive seen one, Im now suprised how early into my recording of trains career i got to see a train go into emergency,
Whoa That Was Uncalled for
Any number of things could've caused them to go into emergency stop. A knuckle arm could snap causing one of the cars to uncouple the trains onboard computer could've detected a hydraulic leak coolant problems in the engine it could've been a number of any item that could cause an emergency stop
Hydraulic leak?? Coolant problems. No man. No
Apt description of long train snaking down a railway while hissing from a leaking hose. Scarry and enough to get your attention.
It took 53 seconds for the train to stop 😲
I'm sure we all know that.
No it did not it took 58 seconds
The same thing happened in malaysia too, after getting off an ktmb class 93 at senawang station, i went up the stairs as the train departed but then suddenly heard a loud hiss that scared the crap outta me, and the next second i saw the train stop, the train took a while to get moving again
And no where close to a mile, lol
@@rob7047 took over 1/3 based on the number of cars that went past after brakes were pulled, but it was still less than half a mile I'm sure
Yeah - the train brake hose (charged at 90 psi) uncoupled between 2 cars - the hissing sound - and the train brake is automatically applied full hard! Train probably did not hit anything/anybody!
Awesome video
Yea reminds me too when I was on my regular day of railfan unitill a CSX train going into something like this but by a knuckle break
Imagine if the railroad crossings were so far apart from each other when the freight train goes into emergency stop. There would be a major detour if that happened.
The train got knuckle breaks
Oh that not good
Right
Pretty decent stop. Only took 27 cars to do it.
I live not too far from a BNSF line.
Pretty wild
The definition of Fail-Safe, it failed but It was safe
You never seen a train stop before
I bet something snapped on one of the train cars
More than likely a kicker…
It has blown an some airhose
Seriously bro, your reaction to the train coming to a stop is laughably embarrassing. You're acting like the train overturned and exploded.
