Go to the other thread (link posted above) and read the replies. It’s all explained pretty well there.

“Tampered with?” Sounds more like sabotage to me.

Hmmm. I hadn't thought about it, but you're right. Cutting the power should have ENGAGED the brakes.

Here's the story I read.

so firefighters shut off the engine to stop the flames from spreading. That slowly disengaged the air brakes,

That DOES seem wrong, doesn't it?

40 years ago that nearly happened in Denver.
They had a run-away with a tanker full of chemicals which would have killed at least 10k.

Friend at Shell Chemical told me about it.

The brakes are actuated on a reduction in pressure, but the motive force for the application of the brakes comes from an air reservoir aboard each individual rail-car, not from a spring.

Under the Westinghouse system, therefore, brakes are applied by reducing train line pressure and released by increasing train line pressure. The Westinghouse system is thus fail safe—any failure in the train line, including a separation ("break-in-two") of the train, will cause a loss of train line pressure, causing the brakes to be applied and bringing the train to a stop, thus preventing a runaway train.

But that system is not intended to hold the train indefinitely. It is designed to give the train operators time to set each hand brake on each train car.

Exactly. Brian Ross was criminally negligent to have reported what he did. It was reckless and irresponsible for him to do what he did, but that is the hallmark of his career. Other colossally stupid things he has done is to Smuggle Uranium into the USA just to show how easy it was,


and he is also THE PERSON responsible for rigging that Chevrolet truck to explode when it was hit by another vehicle when he worked for NBC.

That little stunt cost him his job at NBC, but ABC stupidly hired the Jack@ss.

The world would be a better place if people like Brian Ross weren't allowed to create "news."

Train brakes APPLY if there is no pressure. Unless someone has manually cranked them to the off position.

So “bleeding off” would of applied the brakes unless they were manually overridden.

Read the other thread (link posted above) it explains how it happened.

Are the cars interconnected, brake-wise?

I would think so.

Can a leak in one place drain the reservoirs of ALL cars?

I don't know.

Seems like the engine should CHARGE all reservoirs, but not be able to DISCHARGE them.

But I'm no train guy (in case that's not obvious).

It’s a real danger, but workable solutions do not lend themselves to this problem.

Pointing out how they can be exploited by terrorists is reckless endangerment in my opinion.

What the BRAIN DEAD STUPID JACK@SS didn't realize ...

I have ceased to give the MSM any benefit of the doubt. Until solidly proven
otherwise I will assume that Brian Ross and ABC intended to assist terrorists.

The main air supply, that pressures up the reserve tank, as well as holds the brakes open, is connected. Loss of this pressure supply line, closes the brakes, depending on each individual car to hold its own brakes for a time sufficient to apply the hand brakes.

Can a leak in one place drain the reservoirs of ALL cars?

They don't need to all be drained, just enough of them to partially relieve enough pressure. Some were still holding; there was reports of screaming wheels and glowing red brakes.

This could have been sabotage by anti-domestic energy liberals who sabotage trucks and equipment in the United States and Canada regularly.

It is extremely common.

The initial fire between Nantes and Lac-Mégantic that was put out before the train rolled away and caused a far worse fire might have been sabotage. But the reasons this became such a huge disaster really looks like incompetence.

I defer to y’all who know way more than I do about the subject.

That implies that the air brakes alone should NOT be used to "park" the train.

If you're going to walk away, you should put on hand brakes on a majority of cars, I would think.

IN which case, there is no need to keep the engine running, is there? Freezing is not a threat in July.

No worries, when they find the guy he will spend a few years in the looney bin and then be let out on good behavior, you know like the bus head chopper off-er....
