Ever lapsed into daydreaming while you sit at a railroad crossing, waiting for a long freight train to go by?

After a fatal oil train explosion in Quebec last summer killed 47 people and flattened a downtown, people aren’t daydreaming anymore. That disaster served as a wake-up call to a lot of communities living close to railroad tracks, who suddenly realized that was crude oil rolling by in tanker. As oil trains have had more accidents, and governments are examining the safety of rail oil shipments, some local residents are applying the brakes on what they see as a dangerous rush to move oil by train.

There are, however, powerful economic reasons why more oil is being shipped by rail, rather than through pipelines.

 

Reporter Sarah Gardner talked with Graham Brisben, CEO and founder, PLG Consulting, about moving oil by train:

Q: How much crude oil are we moving on trains?

A: It’s certainly growing. It’s up to about 400,000 carloads per year today. Although crude by rail gets a lot of attention — it’s a big focus in the media partly because it’s an area of growth for railroads, but also because there have been a number of high profile crude-by-rail accidents — the reality is it’s only 2 to 3 percent of total car loadings for the railroads.

Q: Why are they using trains to move oil to refineries?

A: Initially, when crude by rail got started, it occurred in the Bakken play in North Dakota. The initial idea was to use rail to get crude to market simply to bide the time until pipelines were built out with enough capacity. But once crude oil got going, the commodity traders and the exploration and production companies realized that rail gave them faster transit times, the ability to ramp up more quickly than pipelines, and the ability to take the crude oil to different destinations where a higher price could be received for those barrels.

Q: There’s not just one price?

A: No. Because crude oil trades at different prices at different places according to oil benchmarks (like West Texas Intermediate, Light Louisiana Sweet and Brent).

Q: Won’t crude by rail go away when more pipelines get built?

A: As the pipeline network gets built out in a north-south direction, the flow of crude from the Bakken in North Dakota will have more of a shift from rail back to pipeline. But going east-west, that business will persist. You’re simply not going to see a buildout of pipelines going east-west. It’s simply cost-prohibitive to go over the Rocky Mountains, for example.

Q: What about tar sands oil from Alberta, Canada?

A: That oil is coming to market both by pipeline and now, increasingly, by rail. First, it was the light, sweet crude out of the Bakken. Now, it’s heavy sour Canadian crude going to U.S. refineries.

Q: Who’s making money on all this?

A: Obviously this has been a bright spot for the railroads. And tank car builders and leasers have enjoyed some very flush returns. The other beneficiary has been commodity traders who take advantage of those price spreads. It’s also a good time to be in the refining business because of abundant domestic supply. They’re in a better position than they were five years ago.

Q: Federal regulators are moving to increase safety standards in light of recent accidents. Will those new regulations affect the economics of crude by rail?

A: Crude by rail is economically attractive enough to warrant the hard work it is going to take to improve safety. The measures that can be taken, in reality, aren’t all that difficult. We expect regulations on retrofitting tank cars with crude oil. Also it wouldn’t surprise me if there end up being routing guidelines away from population centers, along with the speed restrictions. And greater scrutiny of terminal operations.

Q: Railroads seem very old-fashioned somehow. Could we live without them?

A: Could we live? Yes. Could our economy survive without railroads? No.

JACKSON, Mississippi (Reuters) – A Canadian National Railway Co train carrying fuel oil and other hazardous materials derailed and was leaking in southeast Mississippi on Friday, forcing the evacuation of nearby residents, officials said.

No one was injured in the incident which involved the derailment of 21 railcars, eight of which have spilled their contents, a Canadian National Railway spokesman said.

Several of the cars were carrying hazardous materials including fertilizer and methanol, but there was no fire, he said.

The accident, the latest in a string of North American train derailments over the past year, occurred in the city limits of New Augusta in Perry County, near a mobile home park, according to the Mississippi Emergency Management Agency.

Emergency services were on the scene and responding to the accident, local officials said.

Local sheriff Jimmy Dale Smith said that fewer than 20 people have had to be evacuated at last count.

“They’ve got these spills pretty much contained and secured, and we’re working on starting the cleanup process at this point,” Smith said from the scene. “Hopefully we can get everything cleaned up this afternoon and get people in their homes tonight.”

Friday’s accident follows a spate of explosive derailments of trains carrying crude oil over the past year that has raised questions about safety, especially of some older tank cars prone to puncture.

Federal regulators have been studying railcar design and other issues after the accidents, including one last month when a 106-car BNSF Railway Co train carrying crude east crashed into a derailed westbound BNSF grain train near Casselton, North Dakota.

Last July, a runaway oil train derailed and exploded in the center of the Quebec town of Lac-Megantic, killing 47 people.

New instrument for tracking rail failures

One Solution To Ending Train Derailments

Wed, 01/22/2014
Joel Hans, Managing Editor, Manufacturing.net

Amid a few newsworthy derailments of trains carrying crude oil, energy companies and the public alike are concerned about the future of the U.S. rail infrastructure and what can be done in the near future to mitigate potentially serious and deadly incidents. With some 140,000 route-miles of track in the U.S. as of 2011, and thousands of bridges spanning rivers or interstates that must be navigated on a daily basis, there are countless points of failure.

Civil engineers have long been aware of the way that seasonal heating and cooling can affect the very structure of the railroad ties via expansion and contraction, particularly near bridges. To mitigate those affects, engineers have been using expansion joints on bridges, but when it comes to the extreme heat that much of the continental U.S. sees on an annual basis, it’s difficult to engineer a system that can withstand as much as four feet of expansion in a mile-long section of rail.

When this happens, the rail can buckle, a phenomenon known in the industry as a “sun kink,” which are leading causes of train derailments. In the winter, extreme bouts of cold can cause enough contraction to crack ties and pull them apart, to the point where they need to be warmed by up using flaming rope or other methods.

Naturally, the companies that manufacture steel tracks are doing more work to pre-stress rails and joints to minimize these affects. But one company, Alliance Sensors Group, argues that while many engineers within railway companies and mass transit agencies are doing good work to instrument bridges for movement, structural problems or track shifting, many of these inspections are visually-based, and not often enough, which leaves routes open to unnoticed flaws.

Instead, the bridges can be instrumented to determine if there are any flaws in the tracks, which means that railway companies could divert trains and repair the issues before an incident, such as a derailment, takes place.

Alliance Sensors Group has developed a linear sensor that can measure bridge movements and create empirical data on the condition of rails and bridges that can be tracked in real-time. They’re able to survive all the elements that leave railways buckling or cracking, such as extreme cold and heat, along with humidity, rain and snow. An IP67 rating guarantees that it won’t succumb to the elements.

In the photo, the company’s LV-45s have been affixed to the pier and to the bridge using ball joint swivel rodends. With this in place, the system can measure positional changes in three axes and track those changes over time, which means engineers can proactively identify potential problems, or, in the worst case, respond faster to potential derailment incidents. And if that means less trains coming off the tracks, we’re completely onboard.

Accidents Surge as Oil Industry Takes the Train

In North Dakota Town, Virtual Pipelines Prompt Concern
Jim Wilson/The New York Times

CASSELTON, N.D. — Kerry’s Kitchen is where Casselton residents gather for gossip and comfort food, especially the caramel rolls baked fresh every morning. But a fiery rail accident last month only a half mile down the tracks, which prompted residents to evacuate the town, has shattered this calm, along with people’s confidence in the crude-oil convoys that rumble past Kerry’s seven times a day.

What was first seen as a stopgap measure in the absence of pipelines has become a fixture in the nation’s energy landscape — about 200 “virtual pipelines” that snake in endless processions across the horizon daily. It can take more than five minutes for a single oil train, made up of about 100 tank cars, to pass by Kerry’s, giving this bedroom community 20 miles west of Fargo a front-row seat to the growing practice of using trains to carry oil.

“I feel a little on edge — actually very edgy — every time one of those trains passes,” said Kerry Radermacher, who owns the coffee shop. “Most people think we should slow the production, and the trains, down.”

Moving More Oil Over Rails

As domestic oil production has increased rapidly in recent years, more and more of it is being transported by rail because of the lack of pipeline capacity. The trains often travel through populated areas, leading to concerns among residents over the hazards they can pose, including spills and fires.

Casselton is near the center of the great oil and gas boom unleashed these last few years. And it has seen up close how trains have increasingly been used to transport the oil from the new fields of Colorado, Wyoming and North Dakota, in part as a result of delays in the approval of the Keystone XL pipeline. About 400,000 carloads of crude oil traveled by rail last year to the nation’s refineries, up from 9,500 in 2008, according to the Association of American Railroads.

But a series of recent accidents — including one in Quebec last July that killed 47 people and another in Alabama last November — have prompted many to question these shipments and have increased the pressure on regulators to take an urgent look at the safety of the oil shipments.

In the race for profits and energy independence, critics say producers took shortcuts to get the oil to market as quickly as possible without weighing the hazards of train shipments. Today about two-thirds of the production in North Dakota’s Bakken shale oil field rides on rails because of a shortage of pipelines. And more than 10 percent of the nation’s total oil production is shipped by rail. Since March there have been no fewer than 10 large crude spills in the United States and Canada because of rail accidents. The number of gallons spilled in the United States last year, federal records show, far outpaced the total amount spilled by railroads from 1975 to 2012.

Railroad executives, meeting with the transportation secretary and federal regulators recently, pledged to look for ways to make oil convoys safer — including slowing down the trains or rerouting them from heavily populated areas. (Trains go up to roughly 35 miles an hour through towns and at higher speeds outside populated areas.) They also agreed to speed up a review of tougher standards for the train cars used for oil. And last Thursday, safety officials urged regulators to quickly improve industry standards.

“This is an industry that has developed overnight, and they have been playing catch-up with the infrastructure,” said Deborah A. P. Hersman, the chairwoman of the National Transportation Safety Board, which is investigating the Casselton accident. “A lot of what we’ve seen could have been a lot worse.”

But given the fragmented nature of the business — different companies produce the oil, own the rail cars, and run the railroads — there is no firm consensus on what to do. And few analysts expect new regulations this year.

“There was no political pressure to address this issue in the past, but there clearly is now,” said Brigham A. McCown, a former administrator of the Pipeline and Hazardous Materials Safety Administration. “Producers need to understand that rail-car safety can become an impediment to production.”

The stakes are high. In five years, domestic oil production has jumped by 50 percent, to reach 7.5 million barrels a day last year.

But with little pipeline infrastructure, energy producers had to scramble for new ways to get their oil to refiners. Rail was the answer.

“The reality is that this came out of nowhere,” said Anthony B. Hatch, a rail transport consultant. “Rail has gone from near-obsolescence to being critical to oil supplies. It’s as if the buggy-whips were back in style.”

Far more toxic products are shipped on trains. But those products, like chlorine, are transported in pressurized vessels designed to survive an accident. Crude oil, on the other hand, is shipped in a type of tank car that entered service in 1964 and that has been traditionally used for nonflammable hazardous liquids like liquid fertilizers.

Safety officials have warned for more than two decades that these cars were unsuited to carry flammable cargo: their shell can puncture and tears up too easily in a crash.

In 2009, a train carrying ethanol derailed and exploded, killing one person in Cherry Valley, Ill. The National Transportation Safety Board said the inadequate design of the tank cars made them “subject to damage and catastrophic loss of hazardous materials.”

After that accident, railroads and car owners agreed in 2011 to beef up new cars with better protections and thicker steel. But they resisted improving safety features on the existing fleet because of cost. They also argued that thousands of new cars were being ordered anyway, so it would be just a matter of time before the fleet was replaced.

But analysts said that time has run out; railroads and car owners can no longer ignore the liabilities associated with oil trains, which could reach $1 billion in the Quebec accident.

“Quebec shocked the industry,” Mr. Hatch said, adding that while rail safety has improved over all, “the consequences of any accident are rising.”

Last November, the Association of American Railroads said it would support requiring that the 92,000 tank cars used to transport flammable liquids, including crude oil, be retrofitted with better safety features or “aggressively phased out.”

Still, other groups have resisted. The Railway Supply Institute, which represents freight car owners, told regulators three weeks before the Casselton accident that existing cars “already provide substantial protection in the event of a derailment” and suggested minor modifications to be phased in over 10 years.

While the safety record of railroads has improved in recent years, the surge in oil transportation has meant a spike in spill rates. From 1975 to 2012, federal records show, railroads spilled 800,000 gallons of crude oil. Last year alone, they spilled more than 1.15 million gallons, according to the Pipeline and Hazardous Materials Safety Administration. And that figure does not include the Casselton spill, estimated at about 400,000 gallons.

The accidents have also created a sense of weariness among elected officials and even staunch oil backers.

North Dakota Gov. Jack Dalrymple, a Republican, insisted that the first priority was improving tank cars. “These exploding tank cars are obviously very powerful and very dangerous,” he said.

The accidents have brought another problem to light. Crude oil produced in the Bakken appears to be a lot more volatile than other grades of oil, something that could explain why the oil trains have had huge explosions.

Here too, the warnings came too late.

Federal regulators started analyzing samples from a few Bakken wells last year to test their flammability. In an alert issued on Jan. 2, P.H.M.S.A. said the crude posed a “significant fire risk” in an accident.

The Federal Railroad Administration also pointed to rising numbers of oil cars that showed a “form of severe corrosion” on the inside of the tanks, covers and valves.

After the recent meeting with regulators, the American Petroleum Institute pledged it would share its own test data about the oil, which they have said is proprietary.

While the tank cars themselves have not caused any accident, they failed to contain their cargo. That happened on the outskirts of Casselton when a 106-car oil train crashed into a soybean train that derailed on a parallel track.

In a preliminary report, the N.T.S.B. said 18 of the 20 oil tank cars that derailed were punctured. Much of the oil spilled was incinerated by the explosions, and some soaked into nearby corn fields.

Aside from evacuating nearby farms, there was little the fire department could do but watch the train burn.

Tim McLean, Casselton’s fire chief, pictured what the town would look like if an oil train derailed. The large propane supply tank would explode “like a bomb” and incinerate two multifamily houses next to it. Five blocks to the west are a lumber yard and two gasoline stations. Oil might accumulate in storm sewers and possibly spread a fire underground.

“There’s virtually no way we could protect these buildings,” he said as he passed the barber shops, drugstore and pizza parlor, all occupying sturdy brick buildings more than a century old. “It would be too hot.”

The terror of what might have happened hit many here immediately.

Adrian Kieffer, the assistant fire chief, rushed to the accident and spent nearly 12 hours there, finishing at 3 a.m. “When I got home that night, my wife said let’s sell our home and move,” he said.
