Mate, Did you hear a knocking sound ??
This is Canadian National locomotive number 2699. It is a 212 ton machine powered by a 183 litre 4400 hp V16 4 stroke diesel.
Shortly before these picture were taken, whilst working under load, 2699 experienced what is known in the trade as a catastrophic uncontained engine failure. The train was passing the town of Independence , La at the time.
The first picture below shows that one of the 16 cylinder packs that form the engine was ejected through the engine bay body side and thrown clear of the locomotive.It was ejected so violently that it travelled through the air and crashed through the roof of a nearby home where it imbedded itself in an interior wall.
