US oil train safety rule delayed by 1 year

The Obama administration has delayed by nearly a year a plan to boost safety standards for the type of rail car involved in a fiery explosion that killed at least 47 people in Canada this month.
Officials began work on the rule more than a year before an oil train derailed and exploded in Quebec on July 6 but the rule was never put in place.
The proposal by the Pipeline and Hazardous Materials Safety Administration is intended to fix a dangerous design flaw in a rail car commonly used to haul oil and other hazardous liquids from coast to coast.

The soda-can shaped car, known as the DOT-111, has come under scrutiny from safety experts because of its tendency to split open during derailments and other major accidents.
That's exactly what happened on July 6, when an unattended Montreal, Maine & Atlantic Railway train came loose, hurtling down a 7-mile (11-kilometer) incline before derailing and igniting in Lac-Megantic, near the Maine border.
All but one of its 73 cars were carrying crude oil, and at least five exploded, setting off massive explosions that devastated the small lakeside town of 6,000 people.

The structure of the tank car is not believed to be a factor in the derailment, which is under investigation. But transportation experts say the car's underlying design makes it prone to damage and catastrophic loss of hazardous materials.

A proposed rule to beef up rail-car safety was initially scheduled to be put in place last October, but it has been delayed until late September at the earliest. A final rule is not expected until next year.
The pipeline safety agency said in a report this month that the latest delay was needed to allow "additional coordination" among officials and interested groups, including industry representatives who have resisted calls to retrofit existing cars, citing the expense and technical challenges such a requirement would pose.
In the first half of this year, US railroads moved 178,000 carloads of crude oil. That's double the number during the same period last year and 33 times more than during the same period in 2009.

The Railway Association of Canada estimates that as many as 140,000 carloads of crude oil will be shipped on Canada's tracks this year, up from 500 carloads in 2009. Much of that increase is from oil produced in the Bakken oil patch in North Dakota and Montana and surrounding areas.
The train that crashed in Quebec was carrying oil from North Dakota to a refinery in New Brunswick, Canada.
The DOT-111 tank car represents more than two-thirds of the rail fleet carrying crude oil.
