Junk piston

[Gunfreak25]

Does anyone here have a junk or unusable NHC 250 piston laying around? I would love to have one as a desk piece just because they are so darn huge.

A thrown piston....

This is Canadian National locomotive number 2699. It is a 212 ton machine powered by a 183 liter, 4400 hp V16 4 stroke diesel

Shortly before this picture was taken, while 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 the engine exploded and one of the 16 cylinder-packs that form the engine was ejected through the engine bay body side and thrown clear of the locomotive. In addition to this the piston from that cylinder was thrown free by the force of the failure. It was ejected so violently that it traveled through the air and crashed through the roof of a nearby home where it imbedded itself in an interior wall.

My Dad used to work on locomotives. He said he always cringed whenever he was in the engine compartment and they revved the engine. He had seen many "catastrophic uncontained engine failures" and didn't want one to happen while he was in the engine compartment. He talked like these failures were very common at the time (1960s).

Holy crap

Holy crap

The exact words that came to my mind, would have set off almost every politeness alarm on this site!

I live about 2 miles from the CN Rail yard, and have not seen an engine grenade yet. Seen many judgement errors which involved speed and lack of distance. Grain cars bend in really amazing ways!

Hey, congrats on your 1000th post Stan!

WOW, I've seen alot of failures and had a few happen while trucks were in the shop, but none ever that big! Wonder what it sounded like? Wonder what the rod did to the block?

Very cool, thanks for the pics.

Looks like I stole Gunfreak's thread so I started a new thread. I'll delete my post above tomorrow.
