Canadian National Railway (NYSE:CNI) is the most recent company to experience a crude-by-rail accident in what is turning into series of tragic events in the industry. While the Department of Transportation is looking into the flammability of the crude itself, Greenbrier (NYSE:GBX) is hoping to retrofit 80,000 tank cars to make the transportation of oil safer. While new and improved tank cars could keep the number of explosions down, Greenbrier without question will profit enormously if the industry determines new cars are needed.
