TORONTO/OTTAWA Jan 9 Some of the crude-oil
tanker cars on the Canadian National Railway train that
derailed and caught fire in New Brunswick on Tuesday appear to
be of an older type that regulators have warned is vulnerable to
leaks and explosions.
Of the five crude tank cars that derailed, two were older
DOT-111 models, a CN Rail spokesman said on Thursday, citing
information the company received from the Association of
American Railroads (AAR).
The train derailed in a rural area near a small village in
the eastern Canadian province of New Brunswick on Tuesday night.
A total of 19 cars and one locomotive on the 122-car,
four-locomotive train went off the rails.
Three cars were still burning on Thursday and one of them
was a crude tanker.
The U.S. National Transportation Safety Board says older
models of the DOT-111 are vulnerable to leaks and explosions.
The cars have become a focal point in a debate on rail safety
regulation as crude-by-rail shipments across the continent
CN Rail did not specify whether the crude tanker still on
fire was an old or new model or whether the newer versions of
the DOT-111 fared any better than the older ones in the crash.
Three of the five derailed crude tank cars were new DOT-111
models that comply with higher U.S. standards ordered after
October 2011, CN spokesman Mark Hallman said in an email.
"Two of the tank cars of crude oil that derailed in the New
Brunswick incident are the older DOT-111 tank cars that CN and
the rail industry are recommending be phased out or
retrofitted," Hallman said, adding that the vast majority of
tank cars are owned by shippers and by rolling-stock leasing
companies and not by railways.
The crude shipment came from Western Canada, and some of it
was destined for Irving Oil's Saint John refinery, CN and Irving
Oil have said.
Hallman said CN and the Transportation Safety Board (TSB) of
Canada were still investigating the nature of the damage to the
tank cars and the volume of product affected.
While no one was hurt in Tuesday's accident, the derailment
revived memories of a devastating crash last July, when a
runaway train carrying light crude from North Dakota's Bakken
region exploded in the heart of the town of Lac-Megantic,
Quebec, killing 47. That train included DOT-111 cars.
The AAR has urged regulators to improve safety standards for
tank cars carrying flammable liquids and has said old tank cars
must be phased out, and that even new cars require
By contrast, energy producers have urged regulators to put
more emphasis on track safety.
One leading trade group estimates that about 80,000 tank
cars would need costly retrofits to comply with stricter
standards being considered in the United States.
Guy Laporte, the investigator leading the TSB probe into the
crash, said it was too early to say definitively what caused the
derailment of the train, which was also carrying liquid
petroleum gas (LPG). Four of the derailed tankers were carrying
CN said preliminary information indicated that a "wheel
failure" was the cause. Laporte said that a broken rail had been
found at the site of the accident.
"Yesterday we found a cracked wheel on a car near the front
of the train," Laporte said. "This wheel moved on the axle and
lost the track gauge resulting in the derailment of that wheel
set. We also found a broken rail."
He added that only the front part of the train had been
inspected so far.
CN said it was able to gain access to the site late on
Wednesday and was able to move some of the cars that were not on
Two cars carrying LPG and one carrying crude were still
burning on Thursday. There was also a smaller fire of locomotive
fuel, CN said.
