Why We Need Better Oil-Carrying Train Cars Now

U.S. has seen a 400 percent increase in crude oil transportation. So why don’t we have rail cars that are designed to carry it?

On Monday, a train hauling 100 tankers of crude oil derailed in West Virginia. The violent crash punctured several of the tankers. Eventually 19 were engulfed in flames. Now, more questions are swirling about whether these tankers are safe enough to carry crude.

Old cars, new crude

Initially, the crash had many pointing to a seemingly similar accident in Lac-Mégantic, Quebec in 2013, in which crude oil tankers also ignited following a derailment. In the Quebecois crash, many of the tanker cars involved were DOT-111s—a train car not designed to transport flammable crude oil, but that regularly does so on North American rail lines.

Since 2005, the U.S. has seen a 400 percent increase in crude oil transportation

In 2009, four years before the Quebecois crash, the DOT-111 had been flagged by U.S. National Transportation Safety Board as inadequate to carry ethanol and crude oil, chiefly because of its inability to prevent a puncture in the event of a crash. But the NTSB’s recommendations are not legally binding anywhere in North America. More than 100,000 DOT-111s were transporting crude across American and Canadian rails when the Quebec accident occurred, and still are today.

The CSX Corporation, the railway company that owns Monday’s crashed tankers, was quick to point out that the tankers in use in the West Virginia crash were not DOT-111s, but CPC-1232s. But the fact is that a CPC-1232 tanker is just a reinforced, purportedly tougher version of the DOT-111—a redesign put in place after the NTSB’s 2009 warning. The biggest difference between the DOT-111 and the CPC-1232 is that the head shields (the puncture-prone ends of the cylindrical tankers) are more heavily protected.

Enough shielding?

These CPC-1232s are being increasingly used for crude oil transportation, and are planned to eventually phase out the older DOT-111 models. But as the West Virginia accident is shows, the CPC-1232 is also far from disaster-proof.

America needs a crude oil tanker that will not puncture in a crash

Why? Although the CPC-1232 boasts sturdier head shields, both it and the DOT-111 suffer from a much more basic problem: they simply aren’t thick enough overall. Both train cars have a steel shell that measures 7/16 inch thick. That width falls short of the 9/16 inch steel shell that U.S. regulators say would significantly reduce the likelihood of puncture during a derailment. (Granted, the regulators came to this conclusion in January 2014—long after the CPC-1232 redesign.)

A real crude oil tanker

Rather than relying on insufficiently beefed-up old-style tankers — which, when first created, were not designed for crude oil anyway — America needs a crude oil tanker that will not puncture in a crash. It’s more important now than ever: Since 2005, thanks to a glut of oil production, the U.S. has seen a 400 percent increase in crude oil transportation. And that number looks to be rising.

Derailments are rare, and railroad techs and transporters do an impressive job of almost always avoiding them. But they will never be completely unavoidable.

W.Va. oil train derailment was 1 of 3 with safer tank cars

MOUNT CARBON, W.Va. — The fiery derailment of a train carrying crude oil in West Virginia is one of three in the past year involving tank cars that already meet a higher safety standard than what federal law requires — leading some to suggest even tougher requirements that industry representatives say would be costly.

Hundreds of families were evacuated and nearby water treatment plants were temporarily shut down after cars derailed from a train carrying 3 million gallons of North Dakota crude Monday, shooting fireballs into the sky, leaking oil into a Kanawha River tributary and burning down a house nearby. It was snowing at the time, but it is not yet clear if weather was a factor.

The fire smoldered for a third day Wednesday. State public safety division spokesman Larry Messina said the fire was 85 percent contained.

The train’s tanks were a newer model — the 1232 — designed during safety upgrades voluntarily adopted by the industry four years ago. The same model spilled oil and caught fire in Timmins, Ontario on Saturday, and last year in Lynchburg, Virginia.

A series of ruptures and fires have prompted the administration of President Barack Obama to consider requiring upgrades such as thicker tanks, shields to prevent tankers from crumpling, rollover protections and electronic brakes that could make cars stop simultaneously, rather than slam into each other.

If approved, increased safety requirements now under White House review would phase out tens of thousands of older tank cars being used to carry highly flammable liquids.

“This accident is another reminder of the need to improve the safety of transporting hazardous materials by rail,” said Christopher Hart, acting chairman of the National Transportation Safety Board.

Oil industry officials had been opposed to further upgrading the 1232 cars because of costs. But late last year they changed their position and joined with the railway industry to support some upgrades, although they asked for time to make the improvements.

Oil shipments by rail jumped from 9,500 carloads in 2008 to more than 435,000 in 2013, driven by a boom in the Bakken oil patch of North Dakota and Montana, where pipeline limitations force 70 percent of the crude to move by rail, according to American Fuel and Petrochemical Manufacturers.

The downside: Trains hauling Bakken-region oil have been involved in major accidents in Virginia, North Dakota, Oklahoma, Alabama and Canada, where 47 people were killed by an explosive derailment in 2013 in Lac-Megantic, Quebec.

Reports of leaks and other oil releases from tank cars are up as well, from 12 in 2008 to 186 last year, according to Department of Transportation records reviewed by The Associated Press.

Just Saturday — two days before the West Virginia wreck — 29 cars of a 100-car Canadian National Railway train carrying diluted bitumen crude derailed in a remote area 50 miles south of Timmins, Ontario, spilling oil and catching fire. That train was headed from Alberta to Eastern Canada.

The train Monday was bound for an oil shipping depot in Yorktown, Virginia, along the same route where three tanker cars plunged into the James River in Lynchburg, Virginia, prompting an evacuation last year.

The train derailed near unincorporated Mount Carbon just after passing through Montgomery, a town of 1,946, on a stretch where the rails wind past businesses and homes crowded between the water and the steep, tree-covered hills. All but two of the train’s 109 cars were tank cars, and 26 of them left the tracks.

Fire crews had little choice but to let the tanks burn themselves out. Each carried up to 30,000 gallons of crude.

One person — the owner of the destroyed home — was treated for smoke inhalation, but no other injuries were reported, according to the train company, CSX. The two-person crew, an engineer and conductor, managed to decouple the train’s engines from the wreck behind it and walk away unharmed.

The NTSB said its investigators will compare this wreck to others including Lynchburg and one near Casselton, N.D., when a Bakken crude train created a huge fireball that forced the evacuation of the farming town.

No cause has been determined, said CSX regional vice president Randy Cheetham. He said the tracks had been inspected just three days before the wreck.

“They’ll look at train handling, look at the track, look at the cars. But until they get in there and do their investigation, it’s unwise to do any type of speculation,” he said.

By Tuesday evening, power crews were restoring electricity, water treatment plants were going back online, and most of the local residents were back home. Initial tests showed no crude near water plant intake points, state Environmental Protection spokeswoman Kelley Gillenwater said.

State officials do have some say over rail safety.

Railroads are required by federal order to tell state emergency officials where trains carrying Bakken crude are traveling. CSX and other railroads called this information proprietary, but more than 20 states rejected the industry’s argument, informing the public as well as first-responders about the crude moving through their communities.

West Virginia is among those keeping it secret. State officials responded to an AP Freedom of Information request by releasing documents redacted to remove nearly every detail.

There are no plans to reconsider after this latest derailment, said Melissa Cross, a program manager for the West Virginia Division of Homeland Security and Emergency Management.

(Reuters) – An oil train was still on fire and leaking in West Virginia on Tuesday, a day after it derailed and erupted in flames, according to CSX Corp, which said the train was hauling newer model tank cars, not the older versions widely criticized as prone to puncture.

The train, which was carrying North Dakota crude to an oil depot in Yorktown, Virginia, derailed in a small town 33 miles southeast of Charleston, causing 20 tank cars to catch fire. Several were still leaking oil on Tuesday. All the oil tank cars on the 109-car train were CPC 1232 models, CSX said late Monday.

The CPC 1232 is the newer, supposedly tougher version of the DOT-111 car manufactured before 2011, which was faulted by regulators and operators for a number of years. U.S. and Canadian authorities, under pressure to address a spate of fiery accidents, are seeking to phase out the older models. The U.S. Transportation Department has recommended that even these later models be updated with improved braking systems and thicker hulls.

The fires, which destroyed one house and resulted in the evacuation of two nearby towns, were left to burn out on Tuesday, CSX said in a statement. No serious injuries were reported.

CSX said the cleanup of oil will begin when it can safely reach the site. In the meantime, delays are expected on the line.

None of the 25 tank cars that derailed fell into the nearby Kanawha River, CSX said. On Monday, officials said at least one car had entered the river.

Water tests along the Kanawha River have so far come up negative for traces of oil, according to a spokeswoman at the West Virginia Department of Environmental Protection. A nearby water treatment plant has been closed, she said.

This accident followed the Feb. 14 derailment in Ontario of a Canadian National Railways train from Alberta. It was also the second derailment in a year along this CSX line. A similar incident in Virginia involved a train also headed to Plains All American Pipelines LP’s oil depot in Yorktown, Virginia.

A boom in oil rail shipments rail across North America has heightened focus on safety. In July 2013, 47 people were killed in the Quebec town of Lac-Mégantic after a train carrying crude oil derailed and exploded.

Derailment in Dubuque–A Reminder of the Hazards of Transporting Oil by Rail

With at least one million gallons of crude oil and ethanol passing through Iowa on a single freight train, derailments like the one last week a few miles from Dubuque are a major concern.

IPR_Dubuque-derailment“As ethanol dilutes into the water, it’s kind of that process that depletes the oxygen from the water,” says Kevin Baskins, spokesperson for the Iowa Department of Natural Resources. “That’s something we’re going to continue to monitor in the near future.”

Baskins says that the cleanup is going well so far, and they are in the process of sparging air, a process that involves evaporating the ethanol into the air rather that letting it dissolve into the water.

Erin Jordan, reporter with The Gazette and KCRG-TV9, says that derailments with DOT-111s can be especially problematic, as they are vulnerable to puncture in a derailment. DOT-111s are a type of train car commonly used to transport crude oil and ethanol, as well as other hazardous materials.

“A Johnson County commodity study showed, in addition to ethanol, there was also battery acid, anhydrous ammonia, pesticides, paint […] and so you can imagine there would be an environmental effect to those,” she says.

Right now, nine Iowa counties have extra large shipments of crude oil traveling through. While area residents are not notified of what materials are being hauled through their communities, Canadian Pacific Railway’s spokesperson Andy Cummings says they will answer specific questions from emergency responders.

“They can contact the railroad, and we will make that information available to them,” says Andy Cummings. “For security reasons, we do not share details of our dangerous goods movements publicly.”

Canadian Pacific Railway and BNSF Railway Co. also report large shipments of Bakken crude oil to Iowa Homeland Security and Emergency Management.

“There has to be more with respect to openness and disclosure of the chemicals that are being transported,” says Baskins. “When a spill happens, it’s immediate that you have to alert the public, you have to have a plan in place to respond, and you can’t do that if you’re trying to figure out what’s in the chemical that actually spilled.”

On this River to River segment, Ben Kieffer talks with Kevin Baskins and Erin Jordan, as well as David Cwiertny, associate faculty research engineer for the IIHR—Hydroscience & Engineering at the University of Iowa, and Andy Cummings, spokesperson for Canadian Pacific Railway.
