Crews in Lac-Mégantic, Que. resumed the painstaking search for bodies on Sunday after a short break to bring in specialized equipment for the recovery effort.
Authorities have found 42 bodies at the site and are still looking for five more who are feared dead.
Teams took a short pause for the first time on Saturday, two weeks after the train tragedy, while waiting for a crane and other gear to arrive from Montreal.
A few of the derailed rail tankers had to be removed before recovery efforts could continue.
The site of the July 6 crash remains fenced off and inaccessible to residents.
Lac-Mégantic mayor Colette Roy-Laroche said people with homes inside the perimeter will be able to return for a visit early this week to pick up personal belongings.
Originally about 2,000 people were forced from their homes following the explosion.
Just under 200 still can’t go home. Officials say it could be several months or longer before they can return.
“I’d like to thank these people for their patience and collaboration,” Ms. Laroche said at a news conference Sunday.
The area remains a crime scene and there are safety concerns as workers continue to clean up the oil spill.
Meanwhile, the tragedy prompted another outpouring of support from the public.
A fundraising run was organized to make the 12-kilometre trip between Nantes, Que., where the train got loose, and Lac-Mégantic.
