If there was ever a quantified reason (instead of me just being naturally leery of NG powered vehicles)... there you go. I've often wondered how explosive they would be in certain crash situations. Now I vividly see.
By contrast, a train I was backing had a point collision with a truck that disregarded the flagman and "thought" he could clear the tracks. He didn't. It was at about the same speed (or less), and after it was all said and done, it was a basic "non-issue" crossing accident. (No injuries, no severe damage to the truck/trailer, no damage to the rail car.) Only result was the truck driver received his customary "Failed To Yield" ticket for getting himself hit by a train.
Hope the ground crewman riding the point of the above move wasn't severely burned.
