Four hopper cars carrying plastic pellets derailed on the north side of Red Deer on Saturday.
The incident occurred at approximately noon in the Canadian Pacific Railway Ltd. Red Deer rail yard, a spokesperson for the company said Monday.
There were no injuries, no dangerous goods involved and no public safety concerns, Salem Woodrow said. The hopper cars were part of a freight train.
CP immediately enacted its emergency response processes to get teams and equipment to the site and the incident is under investigation, she said.
A witness, who asked not to be identified, reported hearing a louder than usual bang that day. He said he lives in the area where the derailment occurred near Jewell Street and Johnstone Drive, and he often hears rail cars shuffling back and forth.
When he went out for coffee Saturday afternoon, he noticed the derailment, and crews and railway police were there. The derailment cleanup was completed Sunday.
