On Sunday, CN said crews completed that flaring overnight, and trains had started moving again on Saturday.

The derailment happened on Thursday, and officials said about 25 cars carrying various substances derailed just after 10:30 a.m. in the area of 21740 Main St.

More than 300 residents were initially evacuated Thursday as crews examined a leaking train car. Several hours later, they were allowed back into their homes.

There was no threat to public safety, CN said.
