Blame game starts for Quebec train disaster
09 July 2013, 12:02
Chicago - Air brakes that would have prevented the Quebec train disaster failed because they were powered by an engine that was shut down by firefighters, as they dealt with a fire shortly before the calamity occurred, the head of the railway that operated the train said on Monday.
The runaway oil tanker train derailed in Lac-Megantic shortly after 01:00 in the morning on Saturday, exploding in a deadly ball of flames and killing at least 13 people, with another 40 still missing and feared dead.
The train had been parked at a siding on a slope near the town of Nantes, which is 12km west of Lac-Megantic. The volunteer Nantes fire service was called out late on Friday night to deal with an engine fire on one of the train's locomotives.
Nantes fire chief Patrick Lambert told Reuters the crew had switched off the engine as they extinguished a "good-sized" blaze in the engine, probably caused by a fuel or oil line break in the engine.
The problem was that the engine had been left on by the train's engineer to maintain pressure in the air brakes, Ed Burkhardt, chairperson of Montreal, Maine & Atlantic Railway (MMA), said in an interview.
As the pressure gradually "leaked off", the air brakes failed and the train began to slide downhill, he said.
Fire service contacted dispatcher
The fire service said it contacted a local MMA dispatcher in Farnham, Quebec, after the blaze was out. "We told them what we did and how we did it," Lambert said.
Asked whether there had been any discussion about the brakes, he replied: "There was no discussion of the brakes at that time. We were there for the train fire. As for the inspection of the train after the fact, that was up to them."
It was not immediately clear what the MMA dispatcher did after speaking with the fire service. Burkhardt said the fire service should have also tried to contact the train's operator, who was staying at a nearby hotel.
"If the engine was shut off, someone should have made a report to the local railroad about that," he said.
Andre Gendron, 38, lives on a wooded property next to the rail yard in Nantes. He said he was burning a campfire outside his trailer on Friday night when he heard the fire trucks.
"About five minutes after the firemen left, I felt the vibration of a train moving down the track. I then saw the train move by without its lights on," Gendron told Reuters.
"I found it strange its lights weren't on and thought it was an electrical problem on board. It wasn't long after that I heard the explosion. I could see the light from the fires in Lac Megantic."
Still cordoned off
The centre of Lac-Megantic, a lakeside town of 6 000 near the border with Maine, was still cordoned off on Monday morning.
One of the destroyed buildings was a music bar popular with young people, and witnesses reported fleeing the area around the building as the heat and flames closed in.
Police said they had been unable to examine much of the town centre overnight because the area was still too dangerous. Dozens of rail tanker wagons, some of them destroyed, were sprawled around the accident site.
"It's an area that is still extremely risky... The fire service decided they could not allow us to go there for security reasons. We'll see what we can do today," police spokesperson Benoit Richard told reporters on Monday.
Canadian crash investigators said they will look at the two sets of brakes on the train, the air brakes and the hand brakes, as they probe what could turn out to be Canada's deadliest rail accident since 1956.
Burkhardt said that after the pressure leaked out of the air brakes, the hand brakes would not have been strong enough to keep the train in place.
Montreal Maine & Atlantic is one of many North American railroads that have vastly stepped up shipments of crude oil as pipelines from North Dakota and from oil-producing regions in Western Canada fill to capacity, and the accident is bound to raise concern about the practice of transporting oil by rail.
