@@chucklewis9217 Meet you half way. The sudden exit of compressed air in the train line causes the triple valve to dump the air from the emergency reservoir into the brake cylinders. We're both right.
@@B-and-O-Operator-Fairmont really? I thought they were like semi brakes, spring loaded and the air pressure only served to compress the springs and release the brakes.
@@SirFloofy001 All rail cars have a two part reservoir: one side for "service" stops and one side for "emergency". The reservoirs have to be fully charged to release the brakes. When the engineer makes a "service" application, a little air is let out of the brake pipe and the triple valve releases the desired amount from the service reservoir into the brake cylinders that push the shoes against the wheels. There are several levers, fulcrums, and rods to maintain equal pressure against all wheels. An emergency brake application or other sudden loss of brake pipe air causes all the stored air in both sides of the reservoir on each car to dump into the brake cylinders. Very forceful, much more so than a spring-loaded system. There are some good YT videos on how train brakes work. George Westinghouse was a genius. Although there have been improvements to compressors and quicker acting valves, it is still the same concept used today as 1869.
This is actually a good demonstration about why you shouldn’t trespass on the railroad or try to beat the train. You hear the air at 0:34 then hear the first squeal of the brakes at 0:43 ish then the train doesn’t come to a full stop until about 1:29. So almost a minute from when the air dumps to when the train is stopped. Just please please watch this video or any train emergency stop video and you’ll see that trains can’t stop on a dime. After watching you’ll not want to trespass nor try to beat the train. This video was a good example of a train taking a while to stop. Also nice catch brotha
I'm late to comment but better late than never. You're right, and there is a cab video on YT from a train which hit a car which crossed the tracks right in front of the fast-moving train. From impact to complete stop takes 32 seconds and I think it was a passenger train. Even so, the train is almost to the next level crossing before it can fully stop. In another video of the same event taken from a security camera which was on a building opposite the track, you can see that the car passed another vehicle which had stopped to let the train go through. I remember reading that there were 5 people in the car and all of them died in that impact. All because the driver was too impatient to just stop and wait 3 minutes for the train to pass.

Even if it were possible to have the wheels to lock up entirely I don't think it would be a good idea. Wheels that can't turn would not only get flat spots on them, the train would most likely derail. All of that stored up energy has to go somewhere.
It's how military units get all their gear out to the National Training Center in the California desert. Every few years, every Army and Marine Corps combat unit loads up all their stuff to go play war games. There's only so much combat training you can do without actually being in combat, and the NTC at Ft Irwin is designed to get as close as possible to the real thing without exchanging live rounds.
actually that was all in all a smooth stop... there are other vids where you can clearly see a rough stop... but with this one the break was right on the head end, i was expecting some decent run in but it didn't happen

I'd be scared shitless to stop that much mass that fast and not end up all over the place. That was a light load though compared to a train full of aggregate, coal, etc plus the fact this train actually wasn't all that long either.
If that train had have been empty, there was a chance it could’ve derailed. Those flatbed cars are lightweight, so the force from the emergency brake application could’ve potentially lifted the cars off of their trucks.

I have seen the track commands and the daily schedules entered into the dispatch computer. The commands are stacked up and they are sent as soon as the train clears A tanker train will be lined to come south and an intermodal will be next to come north The tanker train drops each signal and clears the blocks Once the absolute control point is cleared, even though they still can't come north because the tanker train has 5 more miles to go, the BCP sends the command string for the blocks and switches and signals from that ACP to the yard 17 miles north The MCPs acknowledge the command string, and execute the commands and report each bit change to the BCP Once the tanker train enters the yard the BCP in the yard sends the command string for the ACPs from the yard to the other ACP controlled by the BCP at the next ACP The BCPs will only send maybe 12 actionable command strings over a 24 hour period 1 for each train committed to come through the line. The MCPs will send hundreds of actionable commands during the same 24 hours, as each indication bit changes With the computer running the trains, instead of having a 30 minute delay between each of the 4 trains coming from the north yard to the south yard, from 1 end of the line to the other, They will FLEET the 4 trains and set that bit and set the FLEET direction bit So, what took 4 hours, now the first train will leave, the second train won't have to wait for a Green Signal The second train will leave 1 minute after the EOT passes out of the yard. It will follow 1 mile behind the first train, and the third train will leave 1 minute after the EOT of the 2nd train leaves the yard, and the 4th train will follow 1 mile behind the third train. So the first train arrives in the yard in 30 minutes and slows as it pulls onto a yard track The second , third and 4th train adjust speeds The first train clears the yard switch and the BCP throws the switch to the track for the second train. The second train pulls in 35 minutes after the first train left the north yard The 3rd and 4th trains adjust their speed The 2nd train clears the yard switch and the BCP throws the switch to the track for the 3rd train and it enters the yard 45 minutes after the first train left the north yard The 4th train adjusts it's speed As soon as the 3rd train clears the yard switch the BCP throws the yard switch to the track for the 4th train. And 1 hour after the first train left the north yard, all 4 trains are in the south yard In 1 hour the computer has done what took humans 4 hours to do All through better communication and control This is actually not new The NYC subways use this exact same system to run their trains They could never run the subway without using this tight control and minimal distance between trains. You see the signals every 100 feet, and it had to be like this because they didn't have computer radio controlled trains back then The signals were used as the active feedback to the train Now it is radio packets going from the locomotive to the 220 MHz PTC ground entry points. And that feeding the dispatch computer and the computer sending packets back out to the locomotives and the ground devices using the BCP It will change the way railroads run
Awesome. I used to switch for General Dynamics with flatcars carrying those M1 Abrams tanks at the front of the consist. Heavy mother fuckers for an old GE center cab switcher.
Wood ties work just fine. In some parts of North America railroads are actually converting back to wood from concrete. Some research is showing that North America's heavy tonnage long distance trains are better suited for wood ties. There are many passionate individuals who argue both sides of this one.
cmphighpower - because they didn't KNOW it was hanging down, dimwit! In any case, it doesn't matter where it is in the train; if any of the pipework gets damaged, the brakes go on.
Have you ever seen a bivouac site? It's very hard to spot either in the desert or open fields. Long-range weapons are useless if you can't see the target. Besides, most insurgents drive up close to an AO, launch a few motars then drive off, hoping they hit something critical.

They told us this is a huge problem
Apparently it is a well known way to make illegal calls in America known in most foreign countries
Many people who don't know anything about PBX systems would get these calls and follow the callers instructions and the call seemed to hang up
In fact they had given unlimited access to the company phone lines and the company would get a phone bill for millions of dollars the next month

We used different 2 digit codes to link sites and each site had a phone patch for emergency

And the salesmen were only looking at the nice commission they were going to make off a 500 dollar sale
Cell phones didn't exist. But a small group of people who I imagine had scanners heard us making phone calls and they started illegally using our towers
It became such a problem that we couldn't use our own towers because they would be on there illegally using our towers all the time.
We had special receivers hooked up and crystaled for a frequency we only used in an emergency to shut down the network
We had to turn off the power to the whole network and then we went out to each site and disconnected the phone lines and we would hear the ** many times, and people who used to get the dial tone would be waiting and they would** again and again and finally got the message that we had disconnected all our phone patches
Now, thanks to encrypted DMR and digital trunking people can't get onto most systems
The railroads are supposed to be switching to NXDN for all their Communications by 2025 and they are supposed to have fully computer controlled trains using PTC
The engineer will be there in case of emergency but the trains will drive themselves
It is supposed to be much smoother and faster than humans
The locomotive will know what the signals are and the locations of all the other trains on the lines and the track switch positions
They will be able to run much closer together and they won't have to wait at sidings and signals
The speed will be adjusted so there is only one or two minutes between one train clearing a switch or block and the next one coming through.
I have seen the track commands and the daily schedules entered into the dispatch computer.
The commands are stacked up and they are sent as soon as the train clears
A tanker train will be lined to come south and an intermodal will be next to come north
The tanker train drops each signal and clears the blocks
Once the absolute control point is cleared, even though they still can't come north because the tanker train has 5 more miles to go, the BCP sends the command string for the blocks and switches and signals from that ACP to the yard 17 miles north
The MCPs acknowledge the command string, and execute the commands and report each bit change to the BCP
Once the tanker train enters the yard the BCP in the yard sends the command string for the ACPs from the yard to the other ACP controlled by the BCP at the next ACP
The BCPs will only send maybe 12 actionable command strings over a 24 hour period
1 for each train committed to come through the line.
The MCPs will send hundreds of actionable commands during the same 24 hours, as each indication bit changes
With the computer running the trains, instead of having a 30 minute delay between each of the 4 trains coming from the north yard to the south yard, from 1 end of the line to the other,
They will FLEET the 4 trains and set that bit and set the FLEET direction bit
So, what took 4 hours, now the first train will leave, the second train won't have to wait for a Green Signal
The second train will leave 1 minute after the EOT passes out of the yard.
It will follow 1 mile behind the first train, and the third train will leave 1 minute after the EOT of the 2nd train leaves the yard, and the 4th train will follow 1 mile behind the third train.
So the first train arrives in the yard in 30 minutes and slows as it pulls onto a yard track
The second , third and 4th train adjust speeds
The first train clears the yard switch and the BCP throws the switch to the track for the second train.
The second train pulls in 35 minutes after the first train left the north yard
The 3rd and 4th trains adjust their speed
The 2nd train clears the yard switch and the BCP throws the switch to the track for the 3rd train and it enters the yard 45 minutes after the first train left the north yard
The 4th train adjusts it's speed
As soon as the 3rd train clears the yard switch the BCP throws the yard switch to the track for the 4th train.
And 1 hour after the first train left the north yard, all 4 trains are in the south yard
In 1 hour the computer has done what took humans 4 hours to do
All through better communication and control
This is actually not new
The NYC subways use this exact same system to run their trains
They could never run the subway without using this tight control and minimal distance between trains.
You see the signals every 100 feet, and it had to be like this because they didn't have computer radio controlled trains back then
The signals were used as the active feedback to the train
Now it is radio packets going from the locomotive to the 220 MHz PTC ground entry points. And that feeding the dispatch computer and the computer sending packets back out to the locomotives and the ground devices using the BCP
It will change the way railroads run
I think the banging is comeing from the flat cars but I'm not too shure
Are the wheels still turning in emergency or do they lock up
They still turn. If the brakes lock up for a significant amount of distance, it tends to destroy the wheels.
Lucky it was just the third car down....
Awesome. I used to switch for General Dynamics with flatcars carrying those M1 Abrams tanks at the front of the consist. Heavy mother fuckers for an old GE center cab switcher.
Wood ties tracks? No CWR tracks on concrete tie like russian trains?
Wood ties work just fine. In some parts of North America railroads are actually converting back to wood from concrete. Some research is showing that North America's heavy tonnage long distance trains are better suited for wood ties. There are many passionate individuals who argue both sides of this one.
At least the conductor don’t have to walk too far
Are these all these Abrams, and Humvees, etc. leftovers from Iraq or Afghanistan or something,
Engineer: "Can we do some stretch braking?"
Radio: "eeeeeeeeeeh, no"
Engineer: "....ok...."
lmao
I started doing it anyway
Come on
imagine how much money is riding on that thing.!!!!!!!
Why not just put car 3 to the end? That way you could avoid that from hitting
At least it was a short walk back to the problem
cmphighpower - because they didn't KNOW it was hanging down, dimwit! In any case, it doesn't matter where it is in the train; if any of the pipework gets damaged, the brakes go on.
@@jackx4311 No need to be rude.
@@jackx4311 always seems like the people who put others down are the ones who only care about making themselves feel better

Might miss a tank or two lol
Time to grab a tank.
The military wasted a lot of money painting those vehicles tan. The enemy had no long range weapons or airplanes, so no need to conceal them.
Have you ever seen a bivouac site? It's very hard to spot either in the desert or open fields. Long-range weapons are useless if you can't see the target. Besides, most insurgents drive up close to an AO, launch a few motars then drive off, hoping they hit something critical.
What color would you have painted them? I mean, you have to paint them with some color. Right? So why do you figure the color 'tan' is a waste.
I don't like the markings on those vehicles!
Putin's trains are getting shorter and shorter to where he will only have the engine left
Dude
Flat spot city !
Tanks lmfao
A whole lotta armor there…. Probably gonna sell it off or donate to all the muni police departments that need them for their drug raids.
proof positive that trains can stop in a hurry
It causes flat spots on the wheels tho and can cause even more damage
@@Shadydudeonthecorner flats spots on wheel is nothing compared to loss of life and damage to private property
I remember running the first Rambo train when we had the first conflict with Iraq 🇮🇶 desert 🏜 storm from fort bliss to the port of Beaumont tx n loaded in the ship to go over sea 🌊 that was done on union pacific Lafayette subdivision
