The Transportation Safety Board is now investigating that CN rail derailment west of Fort Frances.
A team of investigators was deployed after thirty-five cars left the track Friday afternoon, just east of the level crossing on Highway 11-71 in the township of Alberton.
It's reported that two of the cars contained dangerous goods, but nothing spilled.
A small grass fire also broke out, but was quickly extinguished.
No one was injured.
CN says it had the tracks cleared of debris by 6 PM Saturday night, but still expected some rail travel to be delayed going through the area.
