Congratulations to Mr. George Westinghouse on yet another safe emergency stop. There have been improvements to compressor power and valve speeds, but the basic design from 1869 is still in use today.
@@taijuan5087 To be sure, there was trial and error involved. His first idea used air pressure in the train line to apply the brakes. This wasn't fail-safe, so he added car reservoirs to activate the brakes when pipe pressure was reduced or lost completely.
@@taijuan5087 A reduction in brake pipe pressure causes the automatic control valve on the car to release air from the reservoir into the brake cylinders. The force of the air is multiplied in the cylinder to apply the brakes. There are no springs involved in a brake application. A sudden loss of brake pipe pressure will dump all of the reservoir air into the brake cylinder for an emergency application. That's the short course. Every car has its own reservoir, control (triple) valve, and brake cylinder.
Long trains are a beautiful sight, especially manifest trains, and in principle create economies of scales. However, in reality, one has to recognize the physical limits of materials, such as couplers, drawbars, receiving track lengths, etc... And when things go wrong, things really do go badly wrong and a crippled train can tie up the Main for long periods of time, especially if a crew has to walk knee-deep in snow in Northern Ontario at night - which is basically single-track territory. In this case the economic advantage of long trains are lost. This incident fortunately happened in the vicinity of a yard where other crews were available to assist. 2017/04/16.
A most enjoyable video . Love those CN colours . One of the classiest on the high iron . ( wouldn't hurt to run them through the wash rack now & then ) That crew had enough lumber in that consist to build a small city . Nice work on this video 👍
I was also wondering about that train stopping so fast and in a so short distance: this is what DPU's and pusher units do best when a train goes into emergency. Brakes are applied from two different ends at the very same time.
Great catch
I am surprised how quickly it came to a complete stop
You'd be surprised how quickly trains can stop.
... and how far they still move doing that.
One now has to check the wheels for flat spots. 2017/04/16.
Paul, you don't have to check the wheels in Canada. You just pull.
No. One does not have to do that

Amazing development for 1869, with no microchip to program. Maybe Westinghouse had help from extraterrestrial technology?

@@B-and-O-Operator-Fairmont So how does reducing or losing the pipe pressure apply the brakes? Springs?

@@B-and-O-Operator-Fairmont Wow! I'm even more convinced that Geo. Westinghouse had technological help from extraterrestrials.
Some pretty wild train forces there.

Man you can sure tell the accents and I'm from Saskatchewan lol. Never encountered a broken knuckle yet (knock on wood).
Nice radio chatter. He stopped fast! Nice video. :)
Braking starts at 3:34 ;)
Jonah Beale Try 3:37 champ. You hear the air go. Hence emergency brake.
Spoiler alert! Lmao
@@aodhancoultis6550 Actually 3:36, but who's counting? ;)

Oh Yeah , forgot to thank you for showing the signals . We really like to see the signals just as the crew sees them in passing .
It sounds like it blew air hose great video thanks for posting
robert Jackson that was the emergency valves on the cars dumping brake pipe pressure to 0 psi to apply the brakes
Broken knuckle

Probably mostly or all empties. Or the train is on an upgrade. Or both.
@@taijuan5087did you even watch the video?! It's like almost entirely loads on this train.
Great catch just subscribed I see 4 CN SD70M-2 units on iron ore trains where I live
Nice catch! It sure stopped quickly
2 broken knuckles!!!!! wow!!!!
6:15 the voice did a whoopsies
This video is cool those accents are neat keep it up and have a nice day
Sounds like the conductor is a British lad.
With that much lumber it's probably a bugger to stop
Wow what a sighting. How busy is this line?
Good luck with your video
I really like your train video. Joe
Can you repeat that, over..eh!
Great Video!
Awesome!! New subscriber!
About 2.5k to come to a grinding halt
I like train videos on RUclips 😁
6 people who were trespassed because of walking on the tracks disliked this video😂😂
2 breaks at the same time? How often does that happen?
Once a train goes into emergency, it places all sorts of strain on the couplers. Multiple breaks happen now and then.
great video mate very big like and sub.
Nice catch it is 371 not X371 !
X means it's an extra. Q is a regular train.
t uckerton Actually for CN, M is for regular freights (300's), X is for extras, & Q is for the Intermodals (100's).
Oh CN. You're right. My bad!
And L means local
CN has a ton of symbols for trains..
A, B, C, E, F (for reroutes), G, H (for foreign traffic) K, L, M, O, P, Q, S, U, W, X, Z
:)
X371 with broken knuckle
3:57 godzilla roar like
Dispatch sounds impaired . . Geesh.
How come that conductor (532) sounds Australian or British?
200nick2 it’s actually a Quebec French accent
@@easternontariorailfan8132 oh yeah that would make sense. Thanks for the explanation!
@Brockville Railfan that’s definitely not a French Canadian accent.
Laissez le bon temps roulez!
3:35 brakes applied
And the government wants RRs to go to one person crews because of PTC yeah ok atlease in the U.S not sure about Canada.
Lots of liquid containers.
Lots of lumber.
it wood be nice if they tap it
