GREGG, Man. -- Canadian National Railway says some cargo 
spilled when 13 cars in an eastbound freight derailed in 
southern Manitoba.
The accident happened about 7 p.m. Wednesday near the small 
community of Gregg, about 50 kilometres east of Brandon.
CN says in a release that the cars were carrying refinery cracking 
stock, a non-regulated commodity, and that one of them spilled 
some of its load.




The company says the product did not get into any waterway, 
but an emergency plan was activated and crews are working 
with Manitoba environmental officials to clean the ground 
adjacent to the track.
It says there are no reports of injuries and there was no 
threat to public safety.
CN also says the main track has been reopened following 
repairs and investigators are continuing to look for the cause 
of the derailment.
CN was also involved in a fiery derailment on Saturday just 
outside Gogama in northern Ontario.
The track and a bridge were destroyed, and a trace of oil 
product was found in the mouth of the local river system.

There have been three recent CN derailments in northern 
Ontario, including two along a 40-kilometre stretch of track 
about an hour south of Timmins.
On Wednesday, the Canadian government proposed tough 
new standards for rail tank cars used to transport crude oil.
The proposal would require the cars to have outer "jackets," 
a layer of thermal protection, and thicker steel walls.
