Train Emergency Brake Activation At 40 MPH 

The sudden lack of sound when it stops is pretty amazing.

Conductor about to have a nice long walk

2:02 Classic sign of emergency brakes being applied. That loud whoosh is the sound of the air being dumped which applies the brakes to the train. Train brakes work by reducing air pressure, not increasing. This is because of safety reasons. If the brakes were applied with air pressure, and you couldn’t build up air pressure, then you wouldn’t be able to brake. It’s also important if an air hose is broken or inoperable, like in the case of a knuckle failing. You wouldn’t want for the train to lose its braking in the middle of an emergency and having the load of the train that broke off to continue on without stopping, until inevitably rolling a few miles and hitting someone or something.

Only a train can stop a train. Since that emergency braking the earth is spinning slower.

Thats WERY impressive that train can get a full stop in 40 seconds

2:00 - Just after you can hear the air dump from the lines. That's the point when it's emergency brakes are applied.

Love the sound of a train braking all the cars braking the noise and creaking of all the cars.

0:45 amazing doppler effect

2:02 40 mph to 0 mph in 41 sec

Must be a real joy to find the faulty connection on a train with THIS length..

I can see what you mean when you say it is eerie after. It goes from all the normal noise of a train to dead silence.

I worked as a switchman for almost 10 years back in the late 70 ' s and late 80 ' s . Each car, hopper, tank, gondola, container, engine has their own pressure tank that is pressurized from the engine air compressor pumps . There is a diaphragm in the middle of the tank, with equal pressure on both sides the brakes are released . So, at full pressure and at 0 pressure on both sides, the brakes are released . Once all of them are pressurized the brakes are released and the train can travel . If the engine wants to apply brakes, they slowly release some of the pressure in the air line and it releases pressure on one side of the diaphragm in all the car air tanks . The pressure on the other side of the diaphragm pushes the brake levers on the cars and applies the breaks as the engineer releases the pressure more and more . When the engineer stops releasing pressure, the pumps pressurize the tanks on all the cars to push the diaphragm back to center and the brakes are released . When a hose disconnects or the engineer ' shoots the air ' - ( quick rapid release of air ) then the sudden drop in pressure triggers all the tanks on all the cars to shoot the air in that tank and you have emergency braking . You can hear the individual tanks shooting one after the other down the line . When the engine of a train disconnects from the train and causes the brakes to shoot on all the cars, those cars will only stay pressurized with brakes applied for a few to several hours because the pressure slowly bleeds off . Hand brakes must be applied to those cars on the downhill end . Also, on each car is a bleed lever ( usually in the middle of the car - sometimes on the end ) . When a crew then wants to move those cars, they either have to connect the air hose and apply air pressure, or someone has to walk the entire distance of that train and bleed every tank on every car and remove the hand brakes .

Actually, surprisingly fast (40 seconds), considering all the fast-moving weight!

2:43 My mind was so convinced that it was starting to slowly roll backwards, though visually I felt like it was, I kept looking at that white speck on the wheel of that first PROCOR tanker.

one thing I'm impressed by: as those trains are up to several miles long - that's quite a lot of air in the system - and it takes quite some time for the pressure to equalize to the end after then break valve is operated by the conductor - so the loco and first few cars are already fully breaking while the last car still hasn't applied any breaking force - stresses the breaks of the cars near the loco even more as the whole train is still pushing from behind

Easily over 100 cars too! Impressive!

all that momentum... imagine it was a passenger train, flying coffees !!!

That sound at the end was really cool!

3 nites ago, I saw a lady struck by a CPRail train travelling at 40mph. It was an accident. She was on her hands and knees looking under a passing train, looking for her friends. She didn't hear the train coming on track 2. PLEASE be aware of your surroundings around train tracks.

It took the train about 40 seconds to stop which is probably very good as it looked like a heavy train. Figure at 40 mph that is one mile. If it was a 2 man crew the conductor usually is the one to walk back to connect the air hose. Probably a low hanging air hose struck some debris on the track causing the air hose to in- couple. Thanks for sharing.

Geez, that’s one frickin’ long train!!!

Good job, Mr. Westinghouse!

2:42 is super satisfying

The echo once the train fully stops is incredible.

that was quicker than i thought. FYI the engineer is not going back to fix the air hose, that is the conductor.

Something tells me that the Engineer didn't fix anything besides lunch, in the AC, while waiting for the conductor to fix it and walk back to the engine

The whine of the train tracks as it stopped and echoed through the forest seems almost like an movie

Long squeak and then....Silence. If trains made music that was a beautiful ending to its song 🔥

That creaking sound from the breaks, that keeps me up at night. I live right next to a shunting yard. So I just here that and the CUCHUCKUNCUKCUNCHUUUUCK sound, which is calming, but sometimes when a big load is coming in you hear that eeeeeeeek sound, and then you are not calm because its like nails on a chalkboard. Still fun to watch tho.

i'm glad i had headphones on. at the end you can hear a few loud pops. I think that's from one of those tanks. there's probably one that's only half full and it's the sound of slosh! that's really neat! these cars are just big open voids, so that's the sound of the fluid dissipating the remaining energy, and every time it gets to the opposite wall it pings

The trains breaking sounds like my sleep paralysis 2:28

More than 100 train cars and rail tankers pulled by the loco. What a tractive effort and braking so to acceleration calculated to run the loco. 🤟🤟🤟

Not to bad for 40mph must have had a lot of empties

There is a great force behind it. Great catch. Joe

the laws of physics trumps a driver's need to cross the tracks

23 cars passed before it stopped. Maybe it was a light train.

They have to add Railhead miles behind the train because the braking wheels pull the rail forward. This was probably about 100' of rail.

23 1/2 car lengths to stop, accounting for the variables in car length and using the railroad average of 50 feet to a car length, it stopped in 1175 feet. Not too shabby all things considered

First car on that train is an ex-MN&S (Minneapolis Northfield & Southern) hopper. Don't see those often.

Not the engineer, THE CONDUCTOR!

It did pretty well for a train that long

I'm actually surprised at how quick it stopped!

George Westinghouse would be proud.

The fun starts at 2:05. You're welcome.

I can't help but think of the episode of Jame's first crash in TTTE when I watch this

Emergency Brakes: Brakes at the front | therefore, FLYING ESSENTIALS!

Great catch of my favorite CSX GE unit trailing second behind the CP AC4400CW.

I can feel the brakes grinding through my phone 😳😳😳😳

CSX needs a new paint job for that locomotive

Word came in that the Conductor was a new employee, it was a "training exercise" 😁

Bobby Bacala approves this

Nice! When was this?

WHO IN THE BLAZES APPLIED THAT EMERGENCY BRAKE?!?

Yep. That was a full emergency stop. Train must be inspected to see why.

impressive, considering how much weight is involved.

The quiet after the train stops is kind of eerie

Crude oil in lumber it does weigh a lot it changes the earth rotation?

A train going that fast takes over a mile to stop.

Very cool to see!

The place is similar to our country Indonesia. Greetings from Indonesia.

WoW that is impressive and in good timing!!

I've got a picture of the CSX 600 il engine in this train consist from 2000 in NYC with Twin Towers in the background!!!

Break Applied at 2:01 Stopped at 2:44 ( At 2:01 can hear Air Pressure Release Noise)

He did pretty good ... stopped fairly quickly I thought

America, you really don't do things in half! Haha freight trains In the UK (the most I counted) was only about 20

Only train ive ever seen with 0 graffiti 😂

I've always heard these sounds living next to a railroad in my back yard growing up but never knew what the cause was for these sounds. Even today I can still sleep by a passing train. I guess this is also how NYC people are able to sleep through so many sirens and noises at night?? 😜

You know why it went into emergency? Broken knuckle? Broken air hose or what?

jeder container erzählt eine Geschichte. Es sieht so aus als ob alles einen Sinn hätte. Gute Technologie. Das ist was die Leute fasziniert daran.

Top video greetings from luxemburg europ

WOW GOOD EMERGENCY BRAKES!

That's got to be like trying to stop your pickup truck on an iced over pond.

Okay I had to come check, so these strange noises being heard worldwide are definitely NOT train brakes lol

Very good man. Giant and pretty train. I liked your channel. Have great videos. New fan and friend here. Greetings from Brazil 🇧🇷

I haven't ever seen such a big train.

Dear Khang Lu, Thank you for posting this video! Could I please ask you, would there be a way of using this as a sound effect? Many thanks

Nice braking power

He was just brake-checking the train that follows him

for what they are, trains can stop pretty quickly

Damn that's a shit ton of methylamine

Beautiful horn, I forget what kind.

Marshalling loads behind empties, what a time it would be

This popped up when I searched for the volvo trucks emergency break system which literally stops the truck in a fraction of a second. This is the opposite.

I feel like if you have more than 10 carts you brake faster than 5

Neat catch!

0:45 the Doppler effect

these trains need abs :3

Look at all that methylamine 😂

That was really impressive!

i can smell this video

Nice horn sound

how the engineer could find the actual position of disconnected air hose?

Epic work....Big like & respect

JESUS THAT WAS INTENSE HOLY CRAP BRO WHAT THE FIRCK YOU FCRNACNY MAN

That sounded like a broken knuckle. Either down stream or upstream and out of view.

2:41 Godzilla

Does the emergency braking also put engines to idle? Or does the conductor realize the brakes are activated and he puts them to idle himself?

That is intense

makes you respect crossings a bit more. I'd sure hate to go on a 40 second ride down the tracks in my Ford Escort.

Mr white go go go
