[@sockshandle]

No its Automatic airbrakes that apply automatically however there are brakes that relied on air to turn the brakes on not keep them off

[@hotshothogger]

Yes you are correct. To apply the brakes you discharge from the system. To release the brakes you charge the system by sending the air back. I don't believe the videos creator understands what he is talking about. The cars would not collect air if the were not coupled to a locomotive. Were they cut off before being sufficiently charged to apply the emergency brakes? Perhaps.

Let me just make a few small corrections: 1: Any kind of "light beer" is not actual beer. It's water that wants to be beer. 2: This is American beer we're talking about, so at best it's beer flavored water and thus will not be missed. Shame about the engines that got wrecked though.

[@LavenderSystem69]

Leave the small-time microbrews out of this. We got some pretty good beers that're made here in the States... I will agree that Budweiser is NOT one of them, though

[@woodhonky3890]

My understanding is that air pressure releases the brakes on trains, lack of pressure applies them. It is a safety feature that has been in use for many years.

[@SportyMabamba]

Modern air brakes detect change of air pressure in the train line and apply the brake shoes using air stored in the auxiliary reservoir on each car. The AuxRes is recharged from the train line. Repeated applications of the brake will eventually empty the AuxRes without an air supply to refill it. Over time the Aux Res will also leak pressure so that eventually the air brakes become ineffective. This is why applying the correct # of handbrakes on a rake of cars is essential to prevent runaways.

[@Amigafur]

I've lived in several Denver suburbs since I was two. I've never heard of this wreck! Also, when you said "tank cars" I feared they had oil... thankful it was beer, lol.

[@kw900lkevin]

Collecting Air ? how does it collect air and what does that cause ?

[@daniellibich1376]

When those wonder how air brakes work when ignorance on behalf of another switching crew up the tracks from BNSF's 31st yard let about three dozen tanker cars filled with specifically Coors light beer after switching at the beer maker's plant when ignorance on behalf of the switching crew allowed the tanker cars to collect air as the hand brakes weren't set as like the Lac Megantic disaster train crews had said they didn't set the hand brakes on nearly enough rail cars to prevent the train from rolling. While in BNSF's 31st yard the crew of BNSF 2505 and 1535 get an emergency radio message stating the runaway tanker cars were heading towards them when they bail out when a moment too soon the tanker cars slam into the locomotives doing over 40 MPH shearing the body off the frame of 2505 and damaging the long hood of 1535 as 2505 was to be scrapped on the spot and 1535 was moved to the locomotive shops before the damage from the collision was repaired and another long hood was found before 1535 had emerged from the locomotive shops wearing the H4 paint scheme.

[@oron61]

I don't get it. If the air brakes are disconnected, they should be hard on. Letting air into the pipes should put the brakes on, while a vacuum from the locomotive should be what lets the train roll.

[@MrCatalina31768]

oron61 that’s what I was thinking too

[@raoulcruz4404]

oron61 Same thing happened in Commerce City,CA. Runaway cars on a 2% grade. Failed to set the hand brakes. It’s in the ntsb files. May be an explanation there.

[@brownpcsuncedu]

@oron61, you're describing a vacuum brake. That's the way European train brakes (used to) work. North American air brakes release by pumping a lot of air *into* the system. A reduction in pressure (towards atmospheric pressure) applies the brakes, using air that was built up in the car's air reservoir when the brakes were released. The downside of the American system is that air slowly bleeds off from the reservoir, leaving an unattended car (after a couple of days max) with no air brakes at all. (You can also dump the air all at once, allowing switching without hooking up the air brakes.) That appears to have happened here. The upside of the American system is that you've got something like six atmospheres (~90 psi) of pressure to work with instead of one atmosphere, so your brake cylinders can be a *lot* smaller and still provide enough force to stop the train. North American railroad cars are really too heavy to stop with vacuum brakes, if the cylinders are going to be small enough to fit practically on the car.

[@oron61]

I guess there's not a system where standard atmosphere (whether opposed to a vacuum or a high pressure) would have enough power to brake an American freight anything. I want to imagine a massive spring-loaded lever holding the brake pads against the wheels, which can only be lifted by forcing 90 lbs of air into it, but I don't know if that's even physically possible, let alone worth the cost. I guess a proper parked handbrake would involve inserting a set of set metal teeth into a cog around the wheel, but I'm probably wrong abput that too.

[@brownpcsuncedu]

@@oron61 I've had similar thoughts myself about air brakes :-). I bet a lot of folks have. (Certainly the limitations of the system are clear enough.) But I'm nowhere near enough of an engineering genius (mechanical, not train) to figure out something that really beats the Westinghouse design we have now. As far as I'm aware, hand brakes on North American trains use the same brake shoes as the air brakes--the hand brakes are just a second way to apply the same brake shoes, using a ratchet and chain instead of the air system. (As always, I could be wrong.) I think the idea is that, once you have enough force on the brake shoes to stop the wheel rotating and make it slide on the rail, you're just not going to get any more braking action from a cog, and the brake shoes are already there for the air brakes.

[@jordandorsett3106]

1:37 Reversed James in a Mess

[@shawnerz98]

I'm going to ask a dumb question. I thought that if a locomotive is disconnected from a car, the air pressure in the brake lines drop to 0, and the brakes set. Similar to a tractor trailer. Obviously, I'm wrong or this accident would not have happened. So do railcars need air pressure to set their brakes?

[@Hallettjs7957]

You need to find the video of the covered grain hopper runaway out of Grainton, Nebraska that crashed into 2 parked engines outside of Wallace, Nebraska sometime around 2010.

Maybe someone can explain something for me. Why don't they have the air brake system like we have on trucks? If our air lines between truck and trailer are removed or the air pressure in the tanks on truck or trailer drops too low the parking brakes are automatically applied. How come on trains it's the opposite? Wouldn't it be safer to have the air brakes only release when the system is pressurized?

[@david.irza14]

Usually, with most rail cars these days, they actually have spring mounted brakes. They must have air pressure in order for them to be released. Otherwise, you must manually release the brakes via the hand crank.

[@drippinglass]

Exactly... that’s the way air brakes work, even on over the road trucks. The air releases the brakes, and if the line gets disconnected or punctured, the brakes apply.

[@richardhiskett5422]

Your wrong at least for north American railroad freight cars. Having spring brakes would increase the time required for swithing drastically. In N.A railroad brakes work this way. The locomotive pumps up the brakeline to 90 pi or more. This fills 2 air tanks on each car to the set brakepipe pressure. Tomake a service application the brakepipe pressure is reduced by the engineer causing the brake valves on each car to release air into the brake cylinders until the pressure in the service reservoir equals the brakepipe pressure, applying the brakes. To release the brakes the engineer restores the brakepipe back to full pressure. This causes the brake valve to release the air in the brake cylinder and begin recharging the service reservoir back to full brakepipe pressure. All of this takes time, unlike automotive hydraulic brakes, during which any brake application made until the service reservoir is fully recharged will result in reduced braking effort. A switching job involving a cut of cars of any length would rapidly run the locomotives out of air and would then require them to just sit there until they can get everything pumped back up. An emergency brake application applies the full pressure contained in both the service and emergency reservoirs to the brake cylinder resulting in maximum brake effort. The only springs involved in the brake system of rail freight cars are the ones inside the brake valve and the one inside the brake cylinder that causes the piston to retract back into the released position

[@LavenderSystem69]

I guess I don't understand why train airbrakes don't have a spring-driven backup like we have on tractor-trailers for our airbrakes, as well as a mechanism to automatically fire said spring brakes if the air system depletes too thoroughly. Larger combinations like that have so much more destructive power in the event of crew or mechanical failure; it doesn't make sense for there not to be redundant backups

[@Carter-dv4hz]

Why isn't there just a switch in the coupler where if it comes uncoupled the handbrakes apply?

[@donaldmiller9130]

Basic RR question: I was under the impression that modern "air brakes" depended on positive air pressure (from an engine) to "release" train car air brakes. Without an engine to provide this positive pressure, shouldn't these cars' brakes have been automatically "locked " when they were disconnected, thereby avoiding such a calamity?

[@richardmaurer9002]

Was thinking the same thing myself. Why don’t those things have spring brakes?

[@25mfd]

what you said is true, an increase in air pressure in the train line releases the brakes, a reduction of air in the train line applies the brakes... but the air can slowly bleed off over time, gradually releasing the brakes... that's why the rulebook says to apply "a sufficient number of handbrakes" to cars that are not attached to the engine

34 cars left in emergency should not roll in a short time. Sounds like they were switched without air or with just a few of the head cars on air.

[@wargamz9051]

They could've closed both anglecocks and bottled the air too

[@Nscalestuff]

I've been told by a car inspector that an increase in air pressure of around 3 to 4 psi (of course it only happens when its warm outside) can initiate a release of the brakes, but both angle cocks would have to be closed as well. Air won't increase if one end is open. But, yeah I'd say they were flat switching without air. No way in hell an entire cut of cars would have ineffective brakes when left in emergency

The air was bottled

I occasionally work at Freshpack. Right by this. Had no idea

Ok so I now get HOW you get photos of each locomotive and some consists but WHY are there photos of nearly every one?

... I live in Denver, Colorado, and I *never* knew this was a thing.

Probable Cause & Contributing Factors The switchman helper used improper connection of train line air connections (bottling the air, H008) and the crew failed to apply the derail in the derailing position (H303) are also contributing factors. The FRA found that the accident occurred because the crew of Train No.1 failed to secure the equipment prior to cutting away from cars (H021). The FAST analysis indicates fatigue was a factor for all of the employees involved with this accident and is the primary contributing factor (employee’s physical condition, H199).

Okay. I left that crucial piece of information out, I’m sorry.

[@bottomshot4546]

a novice question for you, at 1:38 he states "after a few minutes of collecting air..." how did the cars gain air without a locomotive attached? I assume the brakepipe still had full pressure to keep the brakes released?

[@conditionzero7195]

They could've been trying to run around them so they closed the angle clock to the cars after they popped them. Even a small change in pressure can cause all the cars to release when both ends are closed.
