One month after a train carrying crude oil derailed in Sturgeon County, the Transportation Safety Board of Canada says an inspection of the track in the area -- completed by Canadian National Railway in September -- showed "rail wear limits" had been exceeded and that the condition of the high rail had reached "condemning limits."

CN crews, including dangerous goods and environmental teams, will be at the scene of a train derailment north of Edmonton throughout the day Monday as they work to clean up the site.

People forced to leave their homes because of a train derailment north of Edmonton could begin returning home after 7 p.m., Sturgeon County officials said Sunday evening.
