Wrecks Hit Tougher Oil Railcars
Sturdier train cars built to carry crude oil have failed to prevent spills in recent derailments

In a string of recent oil train derailments in the U.S. and Canada, new and sturdier railroad tanker cars being built to carry a rising tide of crude oil across the continent have failed to prevent ruptures.
These tank cars, called CPC-1232s, are the new workhorses of the soaring crude-by-rail industry, carrying hundreds of thousands of barrels a day across the two countries.
But the four recent accidents are a sign that the new tanker cars are still prone to rupture in a derailment. The ruptures could increase momentum for rules aimed at further reducing the risk of shipping crude by rail.
In the last month, there have been significant derailments of crude-carrying trains in West Virginia and Illinois, plus two in Ontario, including one Saturday in a remote part of the Canadian province.
Each train was hauling the new tank cars, which weren’t able to prevent the crude from escaping, leaking into one river and exploding into several giant fireballs.

“These new type of cars were supposed to be safer, but it’s obvious these cars are not good enough or safe enough,” said Claude Gravelle, a Canadian lawmaker who represents the northern Ontario area where two recent derailments occurred.
On Sunday, emergency workers were still trying to extinguish fires in multiple tank cars after 30 cars of a 94-car Canadian National Railway Co. train laden with Alberta crude derailed Saturday near Gogoma, Ontario. Five cars landed in a waterway.
The energy industry began using rail to transport oil in 2008 because it was a fast and inexpensive way to move growing volumes largely from the Bakken Shale in North Dakota.
In addition, building new pipelines has been expensive and politically fraught. In February, President Barack Obama vetoed legislation to approve the Keystone XL pipeline, which has been under review by the Obama administration for more than six years.
The robustness of tanker cars has become a major focus of efforts to improve the safety of shipping crude by rail. Such shipments have soared from about 21,200 barrels a day in 2009 to 1.04 million barrels a day by the end of 2014, according to government statistics.
As the U.S. shale boom gathered speed, the safety of growing crude shipments by rail has attracted greater scrutiny in the U.S. and Canada, especially after a 2013 derailment in Lac-Mégantic, Quebec, that claimed 47 lives.
Speed limits have been adopted, and a new rule in North Dakota that will take effect next month requires crude from the state to be treated to make the crude less combustible.
The cars involved in the two Ontario derailments and the incidents in West Virginia and Illinois all met the standards introduced by the rail industry in 2011 as a significant upgrade over older models, and were built with thicker shells and pressure-relief devices

There are about 60,000 of the new CPC-1232 tanker cars in use hauling crude oil across North America, as well as about 100,000 of the older models, says the Association of American Railroads.
Last year, the Transportation Department proposed additional new rules for tank cars carrying crude, presenting three main options. One would stick with the CPC-1232, but the other two would make new cars stronger and retrofit existing cars.
The White House is now reviewing these options and is expected to issue recommendations in May.
Ed Greenberg, a spokesman for the Association of American Railroads, said the railroad-industry trade group “wants all tank cars carrying crude oil, including the CPC-1232, to be upgraded by retrofitting or taken out of service. Railroads share the public’s deep concern regarding the safe movement of crude oil by rail.”
The American Petroleum Institute, the oil industry’s trade group, says it also supports upgrades to the tanker fleet to improve safety.
Cynthia Quarterman, a former director of the Pipeline and Hazardous Materials Safety Administration who stepped down last October, said the recent incidents “confirm that the CPC-1232 just doesn’t cut it.”
Tanker-car improvements alone won’t be enough to reduce overall risk, she added. “The crashworthiness of the tank cars does need to be raised, but that’s not enough. There needs to be a comprehensive solution, including better brakes to help minimize pileups.”
The four recent crashes also highlight some of the other risks of carrying crude by rail that seem to be persistent.
Two of the derailments involved Bakken crude from North Dakota, which contains a high level of gas, making it more volatile than other kinds of crude. In the Mount Carbon, W.Va., accident in February, nearly two dozen tankers full of crude derailed and were engulfed in flames, some exploding into fireballs that rose more than 100 feet in the air.
Tests on the crude showed that its vapor pressure, a measure of volatility, exceeded a new regulatory standard that will go into effect next month.
The recent derailments involved long trains that are essentially mobile pipelines as much as a mile long. The BNSF Railway Co. train that derailed and caught fire in Galena, Ill., 160 miles northwest of Chicago, was roughly a mile long and carrying 103 railcars loaded with crude from North Dakota’s Bakken Shale. BNSF is a unit of Berkshire Hathaway Inc.
“We certainly believe that a stronger tank car is necessary and appropriate,” said Mike Treviño, a BNSF spokesman. A Canadian National spokesman said the company is in favor of stronger tank-car design standards.
Sarah Feinberg, the acting Federal Railroad Administrator, said improving the safety of crude transportation will require a multipronged approach. “This situation calls for an all-of-the-above approach—one that addresses the product itself, the tank car it is being carried in, and the way the train is being operated,” she said.
The train in the Canadian National accident in Ontario over the weekend was 94 cars long, while the West Virginia train had 109 tankers full of North Dakota crude oil.
Canadian Transport Minister Lisa Raitt referred to “very long” unit trains last month when she proposed a new tax on crude shipments by rail aimed at building an insurance fund. “With that increased length of car, there’s an increased risk associated with it,” she said.
The number of derailments on long-haul tracks in the U.S. has declined 21% since 2009, according to the Federal Railroad Administration. But the number of train accidents related to “fire” or “violent rupture” climbed to 38 last year from 20 in 2009.

The volatile gases problem isn't going away, so the railroads / drillers / refiners (and pipelines?) will have to come up with a solution.

Of course, if the Saudi government has its way, the Bakken problem will shut itself out of the game.

Interesting article in TRAINS mag this month about the situation.

It would be interesting to get the perspective of the train crew as to what they experience on head end with 100 plus cars of oil sloshing back and forth, especially with dynamic brake engagement.

I don't believe any of the recent incidents were train handling issues. Really, we try to run these trains "kid glove" style. Very easy out on the throttle, start braking a little earlier than normal, just to give it time to settle. Most good engineers do this with every train, but we all take special care when we've got hazmat cars involved. Nobody needs to remind me what my headpin is connected to--and what the consequences are if I make a mistake. I worry more about the other hazmat cars we carry in mixed freight service. I can kill WWAAAAYYY more people if I derail and puncture just one chlorine or LP gas car in the right location.
Newer cars or not, you can't violently throw/crumple/pierce a tank and not expect the vessel to leak out something-add a spark, and boom goes the dynamite.
We had 3 bad derailments this week, but how many trains made it without incident? Fear and paranoia rule our world now. I've been asked by people outside the railroad (friends and family) why they have to move all this dangerous stuff by rail. I have 2 responses. My first one is "if you only knew how much deadly stuff we haul, you'd be moving to Iceland (they don't have railroads there)." As for the tank trains, I tell them "If you want want cheap gas, this is the price you pay."

Bingo! We have a winner here! But as usual, hysteria, hype, and a biased media prevent the facts from being known.

It is less sexy to quantify the benefits of cheap gasoline. But the boost to every family's bottom line is amazing.

It's a big number. USA Today estimated the savings at about $120 a month for the average US family with one car. Add in some savings due to the drop in natural gas prices or heating oil in some regions for an even bigger bonus to the family.

I have a friend in the railroad industry. Basically there is something called bitumin I think or something like it that can be put in with the gas to keep it less volatile, but the cost at each end to do this is very high. So they don't. Also gas is typically not volatile, it is not being "labeled" the right way so it often is more boom bite then it would be. This is what I have been told on the subject. There are other ways to deal with this coming down the pike with nano tech. Eventually as the train moves with tiny nano tech chips it will relay info on the train, power, cars, track in time to dispatch and hq. If a railroad really wanted to solve the problem they would have a track geo train right out front of every oil train or a highrailer looking for bad track. What the media has said little about is actually how slow each train was going when these 4 derailed.
The media did point out the Metra motor derailment in Chicago area and the Amtrak vs semi in NC. These could have been just as bad if not much worse then the 4 oil train derailments. If I was on that amtrak train and found out the semi had a state police escort I would be getting a lawyer and asking 1 why did the police not make sure the truck could make the turn there and 2 why did they not contact the railroad to let them know they were coming that way?

Bitumen or "dilbit" is thick oil, such as Canadian sands oil and requires a lighter oil mix to thin it out for shipment. One of the leading thinners is condensate, a lightly treated crude oil which is now authorized for limited exports from the US

The feds have concluded that the Bakken oil sometimes contains high levels of hydrogen sulfide and certain oily liquids. The actual amount varies from well to well. One problem has been the oil was not properly measured, and is tendered to the rails and pipes with incorrect lading.

New rules requiring accurate measurements should reduce that part of the problem, and new rules requiring separation of the natural gas liquids should reduce the volatility problem to a more manageable level.
