Fewer Oil Trains Ply America’s Rails

Safety concerns, low crude prices depress train traffic

The growth in oil-train shipments fueled by the U.S. energy boom has stalled in recent months, dampened by safety problems and low crude prices.

The number of train cars carrying crude and other petroleum products peaked last fall, according to data from the Association of American Railroads, and began edging down. In March, oil-train traffic was down 7% on a year-over-year basis.

Railroads have been a major beneficiary of the U.S. energy boom, as oil companies turned to trains to move crude to refineries from remote oil fields in North Dakota and other areas not served by pipelines. Rail shipments of oil have expanded from 20 million barrels in 2010 to just under 374 million barrels last year, according to the U.S. Energy Information Administration.

About 1.38 million barrels a day of oil and fuels like gasoline rode the rails in March, versus an average of 1.5 million barrels a day in the same period a year ago, according to a Wall Street Journal analysis of the railroad association’s data.

Oil-train traffic declined 1% in the fourth quarter of 2014 as crude-oil prices started to tumble toward $50 a barrel. More recently, data from the U.S. Energy Department show oil-train movements out of the prolific Bakken Shale in North Dakota have leveled off as drillers there have begun to pump less, though oil-train shipments from the Rocky Mountain region have risen.

The slowdown comes as federal safety experts call for stronger tank cars. On Monday the National Transportation Safety Board recommended an aggressive five-year schedule for phasing out or upgrading older railcars used to haul crude-oil. A string of oil train accidents in recent months have resulted in spills, intense fires and community evacuations. The NTSB said railcars in use today rupture too quickly and aren’t fire-resistant enough.

A few incidents have involved more modern tank cars—the CPC-1232 model. The NTSB also said the new railcar’s design isn’t sturdy enough. “We can’t wait a decade for safer rail cars,” said NTSB Chairman Christopher A. Hart Monday in a letter to federal transportation regulators.

Opponents of a fast phaseout have said that if tougher standards are introduced too quickly it will create a railcar shortage and make some oil train operations unprofitable.

Many refiners, including Philadelphia Energy Solutions, say they are still committed to shipping oil on trains. Chief Executive Phil Rinaldi in December said he likes that railroads don’t require long-term contractual agreements the way pipelines do. That allows his plant managers to buy crude only when it’s needed.

With pipelines, “you have to pay for that transit whether it makes sense or not,” Mr. Rinaldi said. “With rail, that’s not the case.”

Railroad operators have warned investors that their outlook for transporting crude is slightly weaker than it was last year, said David Vernon, a rail analyst at Sanford C. Bernstein & Co.

BNSF Railway Co., which is responsible for about 70% of U.S. oil-train traffic, operated as many as 10 trains a day last year, but is averaging nine a day now, a spokesman said.
