A Canadian Pacific train slammed into a semi at a level crossing near the community of Tilley, between Brooks and Medicine Hat, on Jan. 19, 2013.
The semi was hauling crude oil to Milk River and exploded on impact, burning the truck and lead train car.
The 67-year-old driver and two crew members on the locomotive suffered minor injuries.
The TSB report found that among the contributing factors in the crash were the driver’s lack of familiarity with the route, a lack of what they call “compelling” audio and visual cues at the crossing, and a restricted view from the truck’s cab.
The TSB says the trucking company has taken a number of steps since the crash to improve driver safety, while Transport Canada is looking into the audibility of train horns.
