Jurors in the Lac-Mégantic criminal negligence trial have completed Day 7 of their deliberations without reaching a verdict.
Unlike Tuesday, when they emerged with a letter telling the judge they were at an impasse, the jurors did not surface Wednesday.
The eight men and four women are deciding the fate of Tom Harding, Richard Labrie and Jean Demaitre.
The three are charged in connection with the July 2013 tragedy in which 47 people were killed when a runaway train carrying crude oil derailed and exploded.
All three accused can be found guilty of criminal negligence causing the death of 47 people, while jurors have the option of convicting Harding on one of two other charges: dangerous operation of railway equipment or dangerous operation of railway equipment causing death.
