UPDATE: 5:30 p.m.
The cause of the accident is under investigation but early reports indicate a crew was on the tracks when the rail cars approached without warning.
Cpl. Tammy Douglas says it took a significant effort by rescue crews to deal with those who were trapped in the derailment.
At the section of track where the accident occurred, the rail cars are not connected to train engines, Dave Rushton, the community's regional elected representative said in an interview.
The area is a transfer zone where the loaded rail cars pass through before being connected to locomotives and moved to sawmills elsewhere, he said.
"Somehow the cars got away and ran down the track, and, of course, it's downhill," said Rushton. "It's all gravity feed. They ended up right in behind our community here. It's amazing there wasn't more damage done."
Rushton said a backhoe loader, a speeder car and the workers were on the track when the accident occurred. A speeder car is a rail vehicle used to transport workers on rail tracks.
The train is operated by Western Forest Products, one of the area's major employers.
