A derailment of a CN freight train Wednesday evening blocked traffic for several hours on Kenaston Boulevard.
The southbound train went off the tracks around 7:30 p.m. north of McGillivray Boulevard near Kenaston Commons.
CN spokeswoman Emily Hamer said the derailment involved five cars carrying cement.
The train wasn't carrying dangerous goods and there were no injuries or environmental threats, Hamer said. Crews worked to clear the tracks so traffic could move again.
Kyle, 17, who didn't want to give his last name, said he heard a loud bang while he was in his backyard just east of the tracks. He said he ran out and saw the derailed train.
"It really got loud," he said.
An employee of the Home Sense store across from the tracks said she didn't hear or see anything, but said the derailed cars had been moved farther south.
The derailed cars could be seen tilted at a 45-degree angle, while the front and back of the train appeared to be on the tracks.
