On the one year anniversary of the oil train derailment and explosion that killed 47 people in Lac-Mégantic, Quebec, residents of the community and family members of the victims commemorated the horrific tragedy with a solemn ‘silent march’ in the early hours on Sunday.

A ceremony was held at a local church before hundreds of people walked through the town’s center and crossed the tracks where the deadly train—carrying Bakken formation crude oil from North Dakota and left unattended outside of town—lost the rail in the early hours of July 6, 2013 and exploded near local shops and a bar where many were gathered.

As the Globe and Mail reports:

As the community held a series of events designed to help itself heal from the loss, others across Canada and the U.S. planned events to mark the catastrophe, with many asking whether enough has been done to make sure—as the fossil fuel industry scales up its oil-by-rail operations—that more dealy and destructive derailments don’t follow.

“You would think that the 47 deaths in Lac-Mégantic would bring about big changes in rail safety,” said Keith Steward, a campaigner with Greenpeace Canada. “But the federal government – the only level of government that can regulate what moves on rail lines – has treated this primarily as a public relations problem rather than a public safety problem.”

Across the border from Quebec, residents in neighboring Maine—who have protested the oil trains that also pass through their communities—marked the Lac-Mégantic tragedy with a series of memorials and events designed to honor the 47 victims and remind the public of the dangers still posed by the increasing number of rail cars moving across the state.
