Safer rail cars gather dust as ethanol trains grow longer

Shippers are slow to upgrade after deadly Quebec derailment

NEW YORK — While crossing a small wooden bridge March 10 near Graettinger in Palo Alto County, about 20 rail tank cars in a milelong train transporting ethanol flew off the tracks, sending fireballs into the sky, while thousands of gallons of the biofuel leaked into the creek below.

No one was injured, in part because the accident happened in a sparsely populated area. A similar derailment in the more dense Lac-Mégantic, Quebec, Canada, in 2013 killed 47 people after a train carrying crude oil crashed and exploded.

But the incident near Graettinger underscores the growing risk of another serious accident along with the increasing volume of the biofuel being moved in unit trains that are milelong with about 100 rail cars — dubbed “rolling pipelines” — to slash freight costs.

That is because ethanol shippers still are primarily using the type of rail cars that were deemed too unsafe to carry crude after the Quebec disaster, even though the biofuel is more explosive than oil.

Thousands of replacement cars meant to better withstand an accident are sitting idle in rail yards around the country because the ethanol industry is not required to use them for another six years and as they cost about three time as much as the older cars, according to industry sources.

The U.S. Pipeline and Hazardous Material Safety Administration gave the ethanol industry until 2023 to employ cars with thicker shells and other safety features. Before the Graettinger incident, the agency said it does not see any safety issues with relying on older cars, known as DOT-111s.

Not everyone agrees.

“We would like to see the shippers accelerate their schedule to get these legacy DOT-111 tank cars out of service when transporting flammable liquids — specifically crude oil and ethanol,” said Robert Sumwalt, member of the National Transportation Safety Board, an independent federal agency, at a news briefing March 11 after the Graettinger accident.


The train in that accident was heading from Green Plains Inc.’s Superior, Iowa, terminal to the Gulf Coast. Green Plains did not comment for this story.

The Renewable Fuels Association, which represents biofuels producers and shippers, said safety is a top priority for the industry and highlighted the rarity of these incidents.

The NTSB has no regulatory authority to change things, Sumwalt said, adding that the power is vested with Congress.


Ethanol production has grown sharply in the past decade, thanks to government rules mandating increased use of the corn-based biofuel to reduce greenhouse gas emissions. Production now is about 1 million barrels per day.

About 650,000 barrels of ethanol is transported by rail daily. A 2015 report by the Federal Railroad Administration estimated about 47 percent of ethanol shipments were by unit trains.

But several sources interviewed, including four shippers, said their use is increasing because of cost efficiencies.

“Unit trains have been an increasing transportation efficiency ... we are encouraged to do more unit trains,” Kelly Davis, director of regulatory affairs at the Renewable Fuels Association, said at an NTSB roundtable last summer.

“Shippers want to use unit trains if they can to save money,” said Tom Williamson, a broker and owner of Sarasota, Fla.-based Transportation Consultants. He said 11 of his 12 clients have switched to unit trains in the past two years.

In the past two years, biofuels makers Archer Daniels Midland, Green Plains and Eco-Energy Global Biofuels as well as terminal operator Kinder Morgan have planned or built new unit train terminals.

Eco-Energy did not respond to requests for comment, while Kinder Morgan declined to comment. ADM, in a statement, said it is committed to making needed investments to meet new rail safety standards.


Federal regulators have warned longer trains hauling hazardous materials increase the risk of disasters, particularly when using DOT-111 cars.

There have been at least 17 significant ethanol or crude derailments since 2006, and nearly all involved DOT-111s.

U.S. regulators gave the ethanol industry more time to shift because getting oil producers to stop using older cars was considered more important. A 2014 Federal Railroad Administration study found ethanol cars are 1.5 times more likely to explode than oil.

As of September, 35,252 tank cars were hauling ethanol, and 84 percent were DOT-111s, according to the Association of American Railroads data. Newer DOT-117s account for only 6 percent of the ethanol fleet.

Based on current lease rates, a shipper using 1,000 of the older cars instead of the new models would save $5.4 million annually.

BNSF Railway has started offering discounts to ethanol shippers next month if they agree to use DOT-117s.


Shippers generally have stuck with older cars because most railcar owners would hit shippers with financial penalties if they break long-term leases.

“While we are having some success in getting ethanol customers to upgrade to DOT-117s when their leases expire, we are not seeing a lot of demand from customers to make this switch,” said Christopher LaHurd, a spokesman with GATX Corp., a leading U.S. leaser of rail cars.

Current lease rates for DOT-111s are about $200 a month, while DOT-117s are about $650 a month, brokers said.

In addition to GATX, Wells Fargo, Bank of America and Greenbrier Cos. are among the U.S. fleet owners.

Spokesmen for Bank of America and Greenbrier declined to comment. A Wells Fargo spokeswoman said the company is working with customers to shift to newer cars.

It would cost billions of dollars to replace all the older cars with 117 model cars, Davis said.

“Owners paid $100,000 for these (current) cars, and you’re going to melt them down like a tin can to make a new one,” Davis said. “That’s a lot of stranded capital.”
