Train dispatcher/engineer

Ysa

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

Yea they do lol. Literally daily

@@infonitemusic9841 I hope they do, BUT NOT TO THEM DAM'N CELLPHONES!

Sounds like they blew out a brake hose

I like that hiss when it dumps the air.

I'm positive there's another locomotive in the middle or rear

THE TRAIN HAS TO STOP 🛑 CN RST709 TRAIN

So your saying that my video sucks?

IKR?

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.

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

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.

@@Canadsergiop oh

@@Canadsergiop youre not going to lose all air pressure no matter where a hose breaks

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

It will always sound like it blows an air line, whether or not it actually does.

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.

They are starting to climb a hill too.

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.

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.
