What happened there was most likely an oil-seal failure on the turbo, which allowed the engine to pull lube oil into the cylinders.  The led to a "runaway" diesel- the old 318 Detroit Diesel truck/bus engines were known for this.  When this happens, there is no way to shut the engine down other than blocking its air supply, not easily done with something this size.  If you listen, it's running at a VERY high RPM.  It probably kept running until it ran out of lube oil, or grenaded itself.  I'm guessing the latter.

On a truck with a manual transmission you can stop, apply the brakes, shift into a high gear and slowly let out the clutch to stall the engine.  Of course that isn't an option on a diesel electric locomotive.

 

If there is no emergency shut down to cut off the air supply a blanket or tarp can be used to cover air intakes.  If all else fails discharging a CO2 fire extinguisher into the air intake can shut down a runaway diesel although hitting a hot engine with 100 below CO2 risks serious engine damage.  Those fire engines should have tarps and CO2 extinguishers on board.  I wonder how this ended?

I was going to mention that I have a friend that worked on the San Bernardino yards years ago would tell me stories of just that. Basically go get something to drink and wait and once the engine becomes a slug then it was time to get to work.

 

Or this could be a prototype MTH locomotive......

Just think how well this would work with 2 or 3 of these units in alashup  

 

Ooh, did I say that out loud?

The subtitle to this video could have been "MTH smoke units gone wild".
