This is a Canadian National locomotive that is by a 4 stroke, V16, 4400 Hp, 183 liter diesel. Unfortunately, it had catastrophic engine failure. While the train was passing through Independence, Louisiana, the engine exploded and one of the 16 cylinder packs was thrown completely through the train. The failure was so violent that the cylinder fell  through a nearby home’s roof and wound up in an interior wall.
