OTTAWA—Canadian investigators said the state of the train tracks in the part of northern Ontario where two oil trains operated by Canadian National Railway Co. derailed recently in separate incidents may have played a part in the accidents.

The Transportation Safety Board of Canada said the second incident, which occurred near Gogama, Ontario, earlier this month, ignited a fireball that led to the destruction of a steel bridge.

It also said Canada’s latest move to toughen standards for railcars carrying crude, unveiled last week after the second derailment in northern Ontario, is promising, but it expressed concerns about the speed at which they will come into effect.

The state of the track in the Gogama region, about 120 miles north of mining center Sudbury, Ontario, was of such concern to the safety board that the agency said it sent a letter to Canada’s Transport Department asking officials take a closer look at the rail infrastructure to determine whether further risk-mitigation measures were required, given the increased popularity of shipping crude oil by rail.

“Petroleum crude-oil unit trains transporting heavily-loaded tank cars will tend to impart higher than usual forces to the track infrastructure during their operation. These higher forces expose any weaknesses that may be present in the track structure, making the track more susceptible to failure,” the board said.

A spokesman for Montreal-based Canadian National said the company is cooperating with investigators and wants to identify “any measures that must be taken to protect the public and the environment.” Meanwhile, the railroad said it has boosted inspection procedures on this northern Ontario rail corridor.

A representative for Canadian Transport Minister Lisa Raitt said the government has asked the railroad to report to officials about concerns raised to date over the March 7 derailment. The spokesman added Ms. Raitt has encouraged lawmakers to call Canadian National executives before a parliamentary committee to testify about rail safety.

The March derailment in northern Ontario involved 39 cars, the safety board said, and caused a fire that burned until March 10. There were no reported injuries.

The incident followed a derailment of another crude-carrying train on Feb. 14. That incident also caused a fire but no injuries.

These incidents were part of a larger number of recent oil train derailments in North America, in which new and sturdier tanker cars being built to carry a rising tide of crude across the continent failed to prevent ruptures.

Canada’s transportation investigator says track infrastructure failures may have played a role in three recent derailments involving oil-laden trains in northern Ontario.

The Transportation Safety Board says it wants Transport Canada to review the risk assessments for a stretch of track known as the CN Ruel subdivision following the fiery derailments in Gogama and Minnipuka.

It says trains have already been ordered to travel slowly on the Class 4 welded rail track due to “various infrastructure and track maintenance issues,” but that heavily loaded tank cars often exert “higher than usual forces” on the track.

The board says that exposes weaknesses in the track and makes it more susceptible to failure.

The agency says its preliminary observations on the March 7 Gogama derailment also found the tank cars performed similarly to those involved in the deadly derailment in Lac-Megantic, Que., despite meeting upgraded safety standards for Class 111 tank cars.

Similar observations were made about a Feb. 14 derailment near the same community, which is about 80 kilometres south of Timmins.

The derailments have fuelled the debate over transporting oil by rail and prompted the transportation ministers of Ontario and Quebec to express concern to their federal counterpart.

Last week, Ottawa proposed tough new standards for rail tank cars used to transport crude oil that would phase out the much-criticized Class 111 tank cars by 2025.

The proposal would require the new tank cars to have outer “jackets,” a layer of thermal protection, and thicker steel walls.

The Transportation Safety Board said Tuesday the proposed standards “look promising,” but must be implemented more quickly than suggested “given initial observations of the performance” of the upgraded Class 111 in recent derailments.

“If older tank cars, including the (upgraded cars), are not phased out sooner, then the regulator and industry need to take more steps to reduce the risk of derailments or consequences following a derailment carrying flammable liquids,” it said.

Federal Railroad Admin: oil industry must do more to boost train safety

Oil industry must join U.S. railroads to boost train safety – regulator

By Patrick Rucker, Mar 13, 2015 6:06pm EDT

WASHINGTON, March 13 (Reuters) – Rail operators are going to great lengths to prevent oil train derailments but the energy sector must do more to prevent accidents from becoming fiery disasters, the leading U.S. rail regulator said on Friday.

Oil train tankers have jumped the tracks in a string of mishaps in recent months that resulted in explosions and fires.

Several of those shipments originated from North Dakota’s Bakken energy fields. Officials have warned that fuel from the region is particularly light and volatile.

Sarah Feinberg, acting head of the Federal Railroad Administration, said the energy industry must do more to control the volatility of its cargo.

“(We) are running out of things that we can put on the railroads to do,” she said. “There have to be other industries that have skin in the game.”

A national safety plan for oil trains, due to be finalized in May, would require trains to have toughened tankers, advanced braking and other safety improvements.

The plan, however, would do nothing to mute the dangers of the fuel itself.

As officials try to prevent mishaps, they will also highlight the energy companies that supplied crude oil involved in accidents, Feinberg said.

Officials want to identify publicly “the owner of the product when we talk about these derailments,” she said.

The American Petroleum Institute said it hoped to work with the rail industry and other stakeholders to prevent mishap.

“Our safety goal, along with the railroads, is zero incidents,” said Brian Straessle, a spokesman for the trade group.

While U.S. officials have warned for more than 12 months that Bakken fuel can be volatile, the verdict is mixed on whether that contributes to the intensity of accidents.

In September, the FRA determined that Bakken crude oil may be no more explosion-prone than other fuels carried by rail.

Ethanol, a corn-based gasoline additive, “poses a similar, if not greater, risk as (Bakken) crude oil when released from a tank car failing catastrophically and resulting in a large fireball type fire,” according to a study from the agency.

On Friday, the FRA said that about 6,000 tankers had a top valve that allowed small amounts of oil to escape. The agency said it ordered the fitting to be replaced and said it would work with industry to identify and replace defective parts more quickly.

That defect was not believed to have played a role in any mishaps, the FRA said.

Speed Limits May Not Stop Fiery Oil Spills, U.S. Rail Chief Says

By Jim Snyder, March 13, 2015 1:15 PM PDT

(Bloomberg) — Lower speed limits for railroads may be ineffective at keeping oil trains on the tracks and preventing massive fireballs, such as those triggered in a series of recent derailments, the chief U.S. railroad regulator said.

“If you’re going to slow trains down, you’re going to have to slow them down to 12 miles an hour,” Sarah Feinberg, acting chief of the Federal Railroad Administration, told reporters in Washington Friday.

“And then you would just have other dangers. People queuing up at grade crossings while train car after train car of volatile product goes by,” she said. “That’s not good either.”

A surge in U.S. oil production has increased the amount of crude moved by rail 5,000 percent since 2009, much of it from North Dakota’s booming Bakken field. A corresponding jump in accidents, including a 2013 oil-train derailment and explosion that killed 47 people in Lac-Megantic, Quebec, have led U.S. and Canadian regulators to propose tougher standards for trains.

Speeds higher than 25 mph were “irresponsible” given the known weakness of the tank cars carrying the crude, Jim Hall, a former chairman of the National Transportation Safety Board, said in written comments to the Transportation Department.

Hall was responding to a proposed department rule that would require the current fleet of tank cars to be replaced. A draft is being reviewed at the White House Office of Management and Budget and is expected to be final in May.

Sloshing Effect

The Federal Railroad Administration also is studying whether slower speeds can cause a sloshing effect in tank cars, making it harder to prevent the rolling stock from wobbling off the tracks, Feinberg said.

Railroads have lobbied against new limits, saying they would result in costly delays for many of the goods hauled by rail.

Two oil-trains that derailed in the past four weeks, in West Virginia and Illinois, and created massive fireballs were traveling well below federal speed limits, Feinberg said.

Railroads last year agreed to slow trains to 40 mph from 50 mph when carrying crude through High Urban Threat Areas, a designation that covers more than three dozen U.S. communities.

“We are running out of things that I think we can ask for the railroads to do, and there have to be other industries that have skin in the game,” Feinberg said. “There also has to be attention placed on the product actually going into the railcar.”

In April, a regulation in North Dakota that requires oil to be kept at a vapor pressure below 13.7 pounds per square inch goes into effect. Feinberg said a process known as conditioning, which companies can use to meet that standard, is the “bare minimum” step to lower volatility.

Feinberg said the administration is considering further steps to reduce oil’s explosiveness before its loaded into tank cars, though the draft rule under review is silent on the issue.
