"It is possible that heat and temperature could have been an issue," said Keith. CN Railway completed cleanup of the derailment on Thursday, said Mary Keith, spokesperson for NB Southern Railway, which assisted. The track is owned by CN but is leased by NB Southern, part of New Brunswick & Maine Railways, a subsidiary of J.D. Keith did say NB Southern has "adjusted" its operations since the derailment "because of the heat." "Heat is an issue this time of year and heat is especially an issue as it relates to the current situation in the province with the heat warnings and high temperatures and what we're seeing by way of extreme fire risks."
