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!
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.
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.
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 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.
