Guys, you should understand diesels. The novelty of picking on Volkswagen has run its course. Unlike those who work a mobile device, I make my living working on real machines. What we see here is a failure, allowing excess fuel to exhaust. The engine does sound uneven, it may be a loss of a cylinder, or more often, a failed turbocharger oil seal. At the worst, those VWs still had a cleaner tailpipe on the inside than the outside.
No problem. Just a non-functioning turbocharger resulting in not enough air to combust all the fuel. The engineer no doubt is aware because the power is way down.
Thank you Ralph. 899 responses and all I needed was your three sentences to satisfy every question and thought that went through my head from watching the short video. THANKS MAN!!
Grey smoke is oil burning from a blown turbo seal or collapsed shaft. If the turbo wasn't boosting air into the engine it would be blowing black smoke, due to rich air/fuel ratio.
Alco stands for American locomotive company. Back during the early days of diesel Alco came out with the ALCO PA which had a troublesome 244 turbocharged engine that would upon accelerating spew out thick black smoke like a steam engine. It's one of the most beloved early examples of diesel engines.
@@sunsetrailfan2004 I am German, so i have not much to do witj America... And of course i know at least a few American locomotives, but id never heard of the short form "ALCO"
Interestingly, the USSR made a direct copy of the Alco design, which I think is still in service over there. Obviously they adjusted it to their slightly broader track gauge.
No chunks of ash, at least. Pure CO2 is infinitely better than whatever sulfur compounds and microscopic ash is in the smoke. Makes me wish the EPA would spend less time worrying about CO2 and toilet bowls, and more time worrying about nuclear test site and olden-day toxic industrial land cleanup.
I remember seeing a similar "fire breathing locomotive" one afternoon, along Route 62 in Princeton, MA. It was on Providence & Worcester's "Train GRWO," (Gardner, from PanAm Railways, back to Worcester) with #3907 in the lead. (GE B39-8?) Video recorded it as it passed, using my dumbphone device. Confirmed it with another rail fan, later viewing this same train in Worcester, MA.
It’s amazing how important dudes with cameras are to professional railroaders. I will admit, though. As a pilot I always follow spotter pages. They will always tell me about a problem at the airport way before the government gets a notice to airmen out about it.
I can tell you as a professional railroader for 15 + years a railfan with a camera has never aided in a situation with the locomotive I was operating. This is synonymous with the rest of my coworkers I have had conversations with about foamers. In this particular instance I can tell you the engineer and conductor are very aware of the situation. There are most likely (not guaranteed) a multitude of alarms and bells going off in the cab, engine most likely is having load/amperage issues, there are side mirrors on the cab, and if any of the traincrew have been around awhile the one positioned on the inside of any turn is looking back when the consist is proceeding through said turn. The last thing this crew is looking at is some "dude" pointing to the obvious.

This is a spokesperson for Norfolk southern and we would like to greatly thank you for pointing at the smoke as our train struggled by, otherwise we would have never known there was a problem. Thank you DORK
@Joel Hacker that not a runaway engine at all. On three things. Bad turbo, failed fuel injector. Or bad piston. A runaway rngine revs at high rpm then locks up then throws rods thru the block.
For those of you who don't understand these diesel trains basically what's going on is they're having issues with the injector so basically it's an injector that's just stuck right open and it's flooding out which is basically the engine trying to burn off all the fuel which creates all that black smoke and then out of nowhere extreme flame of fire
The locomotive runs on desiel so it makes soot the locomotive most likely ran out of DEF diesel exhaust fluid that fluid gets rid of soot overtime the soot builds up on the exhaust pipe and if it gets hot enough it can ignite and cause a fire like what we saw in the video
That's crazy! I've seen J-611 steamer 4-8-4, burn a cleaner stack than that diesel! It looks to me the turbo went probably something got lodged in it. Not getting proper air flow along with a rich mixture of fuel along with oil. Possibly an oil pump or fuel pump going as well. It's definitely a GE, they are known for mechanical issues.
What exactly happens? Does the turbo seize in its bearings? Do the oil seals blow? Does the waste gate stick open? Why does the computer not check for sufficient excess air to be sure that the fuel will be burned BEFORE injecting more fuel?
Blown turbo seals? Or the turbo itself? Only reason I can think of, all that smoke blowing out the exhaust and the prime mover doesn’t automatically shut down.
When i was a Firefighter we got called out for a "Train Fire" so we strike up a full on Haz Mat response,Structure Fire 3rd Alarm.....get on scene we find a slow moving NS Train blowing fire out the Exhaust...cool to see just watched it while it rolled so it didn't light off any brush.
Steve Anderson Its a reference joke to the ALCo diesels, especially the PA units which would produce a large amount of exhaust upon accelerating or running the engine hard.
@@misterjonton1732 ja, mit der DB zu fahren ist manchmal echt ein horror(danke an die Verkehrsminister der letzten 10-15 jahre, habt ihr gut gemacht). (Ich vermute mal du kannst deutsch)
There's actually three distinct conditions of diesel exhaust. White "smoke" is actually unburned fuel vapour, which can ignite in or after the exhaust if there is sufficient heat and oxygen present together. Black smoke is soot from fuel burned inefficiently with insufficient air, producing less energy than the proper mixture would. A faint grey haze indicates correct combustion; from there, the fainter it gets, the more excess air there is.
1:02 - This is essentially what a catalytic converter does but just way cooler. If you can keep that up the whole journey, it will actually be far less polluting
looks like they knew it was obviously pretty broken, but you can see they are on a second track(presumably a siding), assuming train is trying to limp into siding to not block the main/other trains while rescue power makes its way.
I thought it was a runaway at first due to the 'volcanic eruption cloud' appearance of the smoke ... but they throttled it back and it spun down (igniting the fuel in the exhaust in the process). It's a turbo issue.
@@pkranz937 EMD junk? Nope. The 710 engine is bulletproof reliable and is essentially an updated 645. Maybe you're talking about some other EMD component? Plus railroads don't care, as long the loco pulls the train.

Just the excess fuel getting burned. All that smoke is unburned fuel. I'm guessing the turbo seized up or something.

White smoke is unburnt fuel. Enough must have burnt to create heat sufficient to combust the unburnt!
@@jonathoncary6097 hate to be that guy... but unburnt fuel is not white...
But you are correct with the cause... its 100% not getting enough air for all that fuel its getting.
