Three people have been injured, one seriously, after a convoy of semi-trailer trucks collided with a CN train this morning near the hamlet of Islay, approximately 260 km east of Edmonton.

RCMP report a fluid hauler truck in the lead collided with the moving train at secondary Highway 893, south of township 512, at 6:40 a.m. Friday morning.

That first truck then struck another fluid hauler truck that was behind it, according to RCMP. A third fluid hauler truck then hit the train, coming to rest in the ditch.The first truck also hit the ditch, where it rolled.

Eight CN train cars were derailed as a result of the collision.

A male driver with serious injuries was airlifted by STARS to Edmonton, while two of the drivers with minor injuries were treated at the scene. No train personnel were injured.

Cause unknown

Transportation Safety Board investigators from Edmonton should arrive at the scene mid-afternoon, said spokesperson John Cottreau,

Once there they will try to determine what happened and whether a full investigation with a report is needed.

“They’re still uncertain of the cause, if it was weather related,” said Corinne McGirr, communications officer with the County of Vermilion River.

There was some fog in the area Friday morning, she said.

The semi-trailer trucks were all empty and the CN cars were primarily empty, said RCMP.

“Several cars were actually empty and the product that was in the other ones was not deemed hazardous,” McGirr said.

Highway 893, north of Highway 16 up to Township 512, will be closed indefinitely since it will take some time to get the site cleared, she added.

Updates on the highway closure will be posted on the county’s website, Facebook page and Twitter page.

RCMP, CN officials and County of Vermilion River Emergency Services are on scene.
