Runaway freight train explodes, levels center of Canada town

I don’t know how many brakes were tied, or how long the train sat before it rolled away… Too many factors still are unknown.

The railroad industry is a fairly safe industry, but incidents such as this highlight how dangerous the job is on a daily basis.

My initial reaction is someone (trespasser) either decided it would be fun to pull the pin on the cars, or bottle the air. This happens quite a lot! Not sure if the cars that rolled away were the entire train or only partial.

It could be that the locomotive brakes were enough to hold the train in place per the rules. It would be interesting to find out if the air was bottled, or if the angle cock was open.

do not forget the engineer wasn’t the last man to touch that train and maybe the conductor so

need to wait and see .

Al Pomeroy said: the railroad industry needs to better defign to its T&E folks what percentage of the train needs to be set rather than the language “sufficient”

The language is vague by design :wink:
If the train moves, an insufficient number of brakes were set…their employee is at fault.
If they set a percentage in the rules and the train still moves…their procedures and rules are at fault.
Ralph

Given that situation, the prudent “Rail” would set 100% of the brakes, knowing that the suits did not have his back.

Steve,

Have you tied any brakes? They take a long time. When a train stalls on the hill (Stevens) it takes the conductor anywhere from 3-4 hours to tie the train down in good weather.
You learn the territory after a few months, knowing what will hold a train and what wont.

There’s also a difference between a tight hand brake and a loose hand brake. Both are technically ‘tied’ but one has a much better holding power. So I could tie 10 loose brakes or 5 extra tight ones, both being “sufficient” to hold the train.

Craig

Craig,

I do understand where you are coming from, but here is a difference between what is sufficient to keep the train from moving in each situation, and what is necessary to keep the suits from blaming the crew if something goes wrong. It would only take a few times of setting each brake for the suits to realize that they need to set a standard other than “sufficient.”

We had to do that a few times in the Navy. It worked well, as they are not stupid.

Crude oil does not explode - the tanker cars may have hit something that did - LPG cars spotted in the town, maybe?

Whatever, it is a real catastophe for a little town to bear - my thoughts and prayers go out to them all, especially those awaiting news of their loved ones who do not answer the cell-phone call…

All will no doubt be revealed in TSB report - eventually.

Quebec police: 5 dead in oil train derailment

LAC-MEGANTIC, Quebec (AP) - As firefighters doused still burning oil tanker cars, more bodies were recovered Sunday in this devastated town in eastern Quebec, raising the death toll to five after a runaway train derailed, igniting explosions and fires that destroyed the downtown district. With dozens of people reported missing, authorities feared they could find more bodies once they reached the hardest-hit areas.

Quebec provincial police Lt. Michel Brunet said Sunday that about 40 people have been reported missing, but cautioned that the number could fluctuate up or down.

“We met many people who had reported family members missing. Right now I can tell you about 40,” Brunet said.

Brunet confirmed two more deaths early Sunday afternoon after confirming two people were found dead overnight. One death was confirmed Saturday.

All but one of the 73 cars were filled with oil, which was being transported from North Dakota’s Bakken oil region to a refinery in Saint John, New Brunswick.

The eruptions early Saturday morning sent residents of Lac-Megantic scrambling through the streets under the intense heat of towering fireballs and a red glow that illuminated the night sky.

Local Fire Chief Denis Lauzon likened the charred scene to “a war zone.”

“This is really terrible. Our community is grieving and it is taking its toll on us,” Mayor Colette Roy-Laroche said.

On Sunday afternoon, Prime Minister Stephen Harper toured the town where a large part of the downtown area has been leveled.

“This is an unbelievable disaster,” Harper said. “This is a very big disaster in human terms as the extent of this becomes increasingly obvious.”

Harper said the whole country is worried about the missing and is praying forthe town.

“This is an enormous area, 30 buildings just completely destroyed, for all intents and purposes incinerated,” Harper said. “There isn’t a family that is not affected by this.”

The search forvictims in the charred debris was hampered because two tanker cars were still burning Sunday morning, sparking fears of more potentially fatal blasts.

Lauzon said firefighters are staying 500 feet (150 meters) from the burning tankers, which are being doused with water and foam to keep them from overheating.

The multiple blasts came over a span of several hours in the town of 6,000, which is about 155 miles (250 kilometers) east of Montreal and about 10 miles (16 kilometers) west of the Maine border. It is a picturesque lakeside town in Quebec’s Eastern Townships.

The derailment caused at least five tanker cars to explode in the downtown district, a popular area packed with bars that often bustles on summer weekend nights. Police said the first explosion tore through the town shortly after 1 a.m. local time. The fire then spread to several homes.

Brunet said he couldn’t say where the bodies were found exactly because the families have not been notified. Many feared for the lives of those who were at the Musi-Cafe bar where dozens of people were enjoying themselves in the wee hours of a glorious summer night.

Residents who gathered outside a community shelter Sunday hugged and wiped tears as they braced for bad news about missing loved ones.

Henri-Paul Audette headed there with hope of reuniting with his missing brother. Audette, 69, said his brother’s apartment was next to the railroad tracks, very close to the spot where the train derailed.

“I haven’t heard from him since the accident,” he said. “I had thought … that I would see him.”

Another man who came to the shelter said it’s difficult to explain the impact this incident has had on life in Lac-Megantic. About a third of the community was forced out of their homes. David Vachon said he has one friend whose sister is missing and another who is still searching for his mother.

The cause of the accident was believed to be a runaway train, the railroads operator said.

Edward Burkhardt, the president and CEO of Rail World Inc., the parent company of Montreal, Maine & Atlantic Railway, said the train had been parked uphill of Lac-Megantic because the engineer had finished his run. The tanker cars somehow came loose and sped downhill nearly seven miles into the town before derailing.

“We’ve had a very good safety record for these 10 years,” Burkhardt said of the decade-old railroad. “Well, I think we’ve blown it here.”

Joe McGonigle, Montreal, Maine & Atlantic’s vice president of marketing, said the company believes the brakes were the cause. He said the rail company has been in touch with Canada’s Transportation Safety Board.

“Somehow those brakes were released and that’s what is going to be investigated,” McGonigle said in a telephone interview Sunday. “We’re pretty comfortable saying it is the brakes. The train was parked, it was tied up. The brakes were secured. Somehow it got loose.”

Lauzon, the fire chief, said that firefighters in a nearby community were called to a locomotive blaze on the same train a few hours before the derailment. Lauzon said he could not provide additional details about that fire since it was in another jurisdiction. Nantes Fire Chief Patrick Lambert couldn’t be immediately reached, but McGonigle confirmed the fire department showed up after the first engineer tied up and went to a local hotel and after someone reported a fire.

“We know that one of our employees from our engineering department showed up at the same time to assist the fire department. Exactly what they did is being investigated so the engineer wasn’t the last man to touch that train, we know that, but we’re not sure what happened,” McGonigle said.

McGonigle said there was no reason to suspect any criminal or terror-related activity.

Because of limited pipeline capacity in North Dakota’s Bakken region and in Canada, oil producers are increasingly using railroads to transport much of the oil to refineries on the East, Gulf and West coasts, as well as inland. Harper has called railroad transit “far more environmentally challenging” while trying to persuade the Obama administration to approve the controversial Keystone XL pipeline from Canada to the Gulf Coast.

The proliferation of oil trains has raised concerns of a major derailment like this. McGonigle said it is a safe way to transport oil.

“There’s much more hazardous material that moves by rail than crude oil. We think it is safe. We think we have a safe operation. No matter what mode of transportation you are going to have incidents. That’s been proven,” McGonigle said. “This is an unfortunate incident.”

Myrian Marotte, a spokeswoman for the Canadian Red Cross in Lac-Megantic, said there are about 2,000 evacuees and said 163 stayed at their operations center overnight.

Patrons gathered at a nearby bar were sent running for their lives after the thunderous crash and wall of fire blazed through the early morning sky early Saturday. Bernard Theberge, who was outside on the bar’s patio at the time of the crash, feared for the safety of those inside the popular Musi-Cafe when the first explosion went off.

“People started running and the fire ignited almost instantaneously,” he said.

“It was like a movie,” said Theberge, who considered himself fortunate to escape with only second-degree burns on his right arm. “Explosions as if it were scripted - but this was live.”

According to Montreal Maine & Atlantic’s website, the company owns more than 500 miles (800 kilometers) of track serving Maine, Vermont, Quebec and New Brunswick.

Montreal, Maine and Atlantic carried nearly 3 million barrels of oil across Maine last year. Each tank car holds some 30,000 gallons (113,600 liters) of oil.

Maine state officials were notified regarding concerns about the smoke from the fire but staff meteorologists don’t believe it will have a significant impact, Peter Blanchard of the state Department of Environmental Protection said Sunday.

The Maine environmental agency had previously begun developing protection plans for areas in the state through which the oil trains travel.

But Glen Brand, director of the environmentalist Sierra Club’s Maine chapter, said the Quebec derailment is reason enough to call for an immediate moratorium on the rail transport of oil through the state.

“This tragic accident is part of the larger problem of moving oil through Maine and northern New England,” Brand said. “It reinforces the importance of moving away from dirty fossil fuels that expose the people of northern New England, Maine and Quebec to a host of dangerous risks.”

French President Francois Hollande’s office issued a statement offering condolences to the victims in the predominantly French-speaking Canadian province.

Apologies if you have all seen this article already In any event, Fred and I were talking early this morning when he caught me as I came in from milking the chickens…

This -

Craig, you made the statement: “My initial reaction is someone (trespasser) either decided it would be fun to pull the pin on the cars, or bottle the air”

Would you mind explaining these terms to me ?

Pull the pin = uncouple ?

Bottle the air ?

Dave, the actual “fingers” on the knuckle coupler assembly are held closed by a vertical pin which locks the coupler closed. This pin is the entire miracle of the knuckle coupler. (as any good rail historian can tell you) Pulling the pin, dates back to when the couplers all featured the pin being moved up via a chain from the top. Though most modern couplers actually “push” the pin up, the term sticks. So, yes, it does mean to uncouple, and is also used in other cases on the railroad. When guys have had a particularly difficult week, they will often “pull the pin” or mark off their respective board for a day or two to recharge their batteries.

Bottling the air is a term to mean that the brake pipe is sealed off from any vent source. As long as there is a means to prevent an unwanted buildup in air pressure in the brake pipe, the train is safe. But, when the engines are cut away, we are required to allow the brake pipe to vent to the atmosphere. Instead, some guys will leave the brake pipe sealed to save the air for later. This is bottling the air.

Here in PA, our rules require us to secure the train with the handbrakes on the downhill end, so that if someone tries to “pull the pin”, the handbrakes will prevent a runaway. Our rules require that we apply the hand brakes, and then test the train to ensure that the hand brakes are holding the entire train, including the weight of the engines. They also mandate how long we have to wait in order to ensure that the air brakes have in fact released.

Thanks for the quick reply J.D.

WOW the brain power of the members of this board still amaze me.

A couple of things that have yet to appear in print that are important here. 1) the location of the locomotives relative to the derailment. one photo shows the locomotives still on the rail, which makes me wounder if they were seperated from the train upon tieup. if they were the result of a pin pull why are they still on the rails, generally they would be the first to overturn in a speed/curve situation., 2) no report of the so called earlier fire in the other jurastiction , or from the railroads engineering department that was on site.

One thing that i think will come out of this is that hazmat trains will have to be maned in situations like this until relieved by another crew. and I cannot belive that any railroad is allowed to run with single man crew in any circumstance, that is clear negligence of the railroad managment, and the Canadian goverment.

Al P.

JD,

Thanks for the explanation for Dave! The GCOR rules state the similar thing about checking to make sure the hand brakes hold.

Pulling the pin can also refer to someone retiring as well :wink:

So this gets to the question that Al asks, where are the locomotives?

If the train was on a hill, then the slack was stretched and thus impossible for the pin to be pulled (from between the cars). But when you stop on a hill (I’m referring to mountain grade here) the correct way to stop is the following. Locomotives in throttle, with the train streched, set a min. application. This starts to drag the train down (may even stop a light train). Then as the train comes to a stop, you apply the independent. After the independent is applied you throttle off, and place the locomotive in idle (don’t center the reverser!). This causes all the slack to be pulled tight, even between the locomotive and first car. If you throttle off before applying the independent then a small amount of slack is created between the locomotive and the first car. This would allow someone to pull a pin… But that doesn’t solve the answer of how it began to roll.

Edit: For those who don’t know. GCOR= General Code of Operating Rules. The rulebook for railroads operating West of the Mississippi. East of the Mississippi is a similar set of rules, but has a different name. Slightly different rule numbers, but the rules are the same between the two rulebooks.

Nantes Fire Chief Patrick Lambert told Reuters the crew had switched off the engine as they extinguished a “good-sized” blaze in the engine, probably caused by a fuel or oil line break in the engine.

BRAKES FAILED, SAYS CHAIRMAN

The problem was that the engine had been left on by the train’s engineer to maintain pressure in the air brakes, Ed Burkhardt, chairman of Montreal, Maine & Atlantic Railway (MMA), said in an interview. As the pressure gradually “leaked off,” the air brakes failed and the train began to slide downhill, he said.

http://www.odt.co.nz/news/world/264137/canada-train-toll-13-dozens-still-missing

“Burkhardt said that after the pressure leaked out of the airbrakes, the handbrakes would not have been strong enough to keep the train in place.”

This seems contrary to what others here and elsewhere have stated.
Ralph

If the train was secured properly the hand brakes should have held the train. This statement seems to indicate that the hand brakes were not sufficient to hold the train.

Now the other question was the crew dead on the law waiting for a relief crew, or did they actually tie the train down? If they were waiting but dead, the SOP is just to make a 20lb set, and not tie brakes as the locomotive is manned.

Having the system bled down enough to cause a release seems plausible in my mind after hearing about the fire in the locomotive.

Maybe this diagrams will help explain the mechanics of how the air operates.

When they are talking about the air leaking out of the system what they really mean is the air in the holding valve is leaking off, thus causing the brakes to release.

That’s a great illustration. THX!

At this point in time; everyone is speculating. Some of the speculation comes from people who haven’t a clue…others are just trying to help all of us to understand a bit about train braking.

The best idea is to sit back and wait for the CTSB report, that will take time to be investigated, and written.

Fred,

I agree, you can’t lay blame on anyone or anything until the official reports comes out months later.

Hopefully us ‘rails’ have successfully taught everyone how the brakes work, and what we mean by saying things like ‘pulling the pin’ and bottling the air. :wink:
