What is really amazing about this video is someone held the camera horizontal not vertical, didn't say stupid things the entire time, and held the camera steady the entire time. A real rarity!
that's the entire train's air dump to go into emergency. air pressure is applied to remove the brakes. that's how air brakes work. lack of air = brakes are on. it's a fail safe condition. when it goes into emergency all of the air is dumped simultaneously from every car. you're talking 90 pounds of pressure being released on every car, in an instant. yes it's going to sound like an air hose blowing, because that's what it basically is. i wonder what happened. poor conductor has to walk the entire train then until he finds the issue.
@@JJGeneral1 well, sort of. It’s how TRAIN air brakes work, mostly. It’s air that applies the brakes too. With truly no air, there are no brakes, unlike the air brakes on trucks. When there’s truly no air on a truck, a spring applies the brakes. Hence the inherent flaw with train brakes. Once the reservoirs on each car leak down, the brakes release. This is what caused the Lac-Megantic tanker incident.
I believe Perry is right, an air hose must have blown. I drove to the locomotives and there was no collision. I originally thought they may have collided with a vehicle and one of several Brockville level crossings but that was not the case. I was surprised the freight was also moving from the right track to the left track at substantial speed about 500 m from the filming location. This may have contributed to the hose failure.
Lucas plays 6901 nope, sorry Lucas. A broken air hose is independent of the coupler. I don’t think a coupler broke and there was no evidence of a separation but it was a very long train. If an air hose cracks or breaks and all air pressure is lost, the train will go into emergency with all wheels braking which you could see.
If you watch the engine going over that intersection, you can see how much it bounces. I assume one of the lines was loose enough that the bouncing made it pop off.
1:18 The reason why the brakes on these railcars sound so low pitched is because there's an old "GOLDEN WEST SERVICE" railcar which is pretty rare to see, and there's alot of loaded centerbeams, so the loads on the centerbeams make it more heavy, which adds pressure to the axles. So that makes it more low pitched.
Nope, conductor has to walk the train to find the issue. If you have a DP in the middle of the train, you can kinda narrow down where the separation happened based on the flow rate, but besides that, nope there's no way to tell where it happened except by physically walking the train

THE TRAIN HAS TO STOP 🛑 CN RST709 TRAIN
So your saying that my video sucks?
IKR?
Sounds like they blew an air hose at 0:45 in the video.
It will always sound like it blows an air line, whether or not it actually does.

Fantastic train video! I'm a tram and I approve this video! Ding ding!!!
27 cars for emercency, so catastrophic.
Kenny Walls with the 67s game! Love it
What happened? Why did it go into emergency? Did it separate? Did it hit a vehicle or anything? Was the engine broken? Did it stop at a mountain?

@@Canadsergiop wait... if you said it broke a airhose then it means... IT SEPARATED!

@@Canadsergiop oh
@@Canadsergiop youre not going to lose all air pressure no matter where a hose breaks
you can just see the blue smoke coming off a couple of tanks cars when she just starts going into emergency at 1:02
Bubs031 not as much as you could smell it :). I initially thought there was wheel fire but clearly the air was dumped prior.
also known as a hotbox
@@brennenseibert6708 A hotbox is an overheated axle bearing. Has nothing to do with a really hot composite brake shoe. Both are pretty smelly, though.
@@bw4t i know
I'm sure that train had a DPU on it with it being that long with only one engine up in the front.
Chilling when that happens. Especially the dead silence once it stops.
Did you find out he reason why? Always impressed with just how fast that tonnage actually stops.
They are starting to climb a hill too.

I think it was definitely a popped air line. The instant there's that loud hiss pop, it screams into emergency
@Jordan Tyler Unless the rolling stock is extremely old, there will always be a venting of the train line in emergency.
0:44 is what you want to start
I like that hiss when it dumps the air.
Always cool hearing the horn to start off... Impressive how fast that massive momentum came to an abrupt halt👍🇨🇦
Those cars look fully loaded surprised one locomotive at the front
Nice catch, your at the right at the exact correct timing, it happened before your very eyes, nice .👍
what was that dialogue in the background

Great shot, nice clip! Thumbs Up & subscribe
Blew the airline you can hear it
I’ve wondered is there a way for the conductors to know where exactly the hose blew? Either by loss of pressure or some sort of electronic connection.
Nope, conductor has to walk the train to find the issue. If you have a DP in the middle of the train, you can kinda narrow down where the separation happened based on the flow rate, but besides that, nope there's no way to tell where it happened except by physically walking the train
I wonder why the train stopped. Did it hit a car that was going around the gates at a railroad crossing or something?
Sounds like they blew out a brake hose
The engineer's don't wave from the trains anymore, not like they did back in 1954 trackside sees them engineers waving sometimes.
Yea they do lol. Literally daily
@@infonitemusic9841 I hope they do, BUT NOT TO THEM DAM'N CELLPHONES!
my ears!
Someone had to pee! 😳
