A driver was injured after his semi-trailer was hit by a train in the community of Pilot Butte, east of Regina.
It happened around 1:15 p.m. CST Monday at the rail crossing at Butte Street and Railway Avenue.
Darcy Schultz, who works nearby, said he heard the crash from his business.
"Just a big boom kind of thing," Schultz told CBC News. Schultz said he ran to the crash scene and found the driver had been thrown from the cab.
"The guy was trapped underneath the driver side fuel tank."
Emergency crews arrived and the driver of the semi, a 48-year-old Regina man, was taken to hospital with serious injuries.
No one on the train was injured.
Police said roads in the area were blocked for a considerable time while the crash was investigated. The wreckage of the semi was pulled from the road around 9:45 p.m.
There was no immediate word on the cause of the crash.
