Just over a year ago, a railway car full of asphalt rolled away from the Co-Op refinery and headed towards Regina’s downtown core unattended.
The Transportation Safety Board has released its report into what happened and say there was inadequate braking.
The board says the tanker was left unattended by a crew and had been secured by emergency air brakes which slowly lost pressure until they were released.
The tanker, crossed a number of streets at a speed of about 30 kilometers an hour, before coming to a stop on the tracks near the Toys R Us outlet on Albert Street.
No one was injured.
