- IBCX 814, an Ex-EJE, Exx-DMIR SD-M (rebuilt SD9) shoves a string of loads up the hill in Union Mills, IN. IBCX 7042 is also helping with the shove, but you cannot hear it over the SD-M. This locomotive was built in 1956, and has been rebuilt. It still sounds great after all these years!

Smoke is mostly caused by too much fuel being injected. With the locomotive in run 8, the governor makes the generator load harder and harder, and in turn injecting more fuel to maintain a steady RPM. The smoke starts as the engine is being worked harder and more fuel is injected. When almost the max amount of fuel is being injected, a switch is tripped in the governor, causing it to unload some and reduce fuel, hence the starting and stopping smoke. The other thing that would cause it to load and unload would be wheel slip, which was not much of a problem today. Just pure EMD working hard.
That also called Rolling Coal
I was meaning to ask about that. I've frequently noticed that some of the older EMDs seem to constantly throttle up and down like this... I always assumed this was just because of worn out hydraulic governors, but this video shows a pattern that is too rhythmic to attribute solely to that. I had suspected that there might have been something weird going on with the DC traction motors and the way that they are wound, but they would almost have to have some kind of a short somewhere in the commutator or something to produce such a drastic effect.
I wonder then if the prime mover is loading irregularly at low speeds simply due to the poor output voltage control you mentioned, or if it is actually a symptom of a deeper problem. Could it be that the engine is being starved for air by the roots blower and therefore not running at full capable power? A rich fuel mixture that produces that much smoke is essentially blowing unburned fuel into the atmosphere, so it could very well be that there is a clogged air filter or the likes preventing this locomotive from running wide open.
Load controller picks up load to normal value -> engine can't get enough air to match increase in fuel input, starts to flood -> load controller dumps load?
I would love to park one of these in front of Obama's new home and run it in notch-8 day and night with black smoke bleaching out.
Wheel slipping. The light is blinking its traction control warning on the console at each flare up on the rpm. Don't think the sand is on.
Can't imagine why. Even an old diesel-electric is a shining example of efficiency and low emissions per mass moved. Moreover, they're a perfect example of the benefits of hybrid-electric technology. Ergo why passenger rail is a favourite champion of the left...
Gotta love these first gen EMDs getting it done
The EMD 567 is my favorite diesel engine sound!
Facts
@@UnionCountyPhotography I second that
Except this doesn't have the original 567. These were rebuilt with 645 power assemblies; hence the reason why the exhaust doesn't have the telltale sound of a true 567.
567 prime mover + Roots blower = Perfection 😍
That right there is pure EMD 567 music! Excellent video!

Thanks, Jim
My ears are in they're happy place
id sleep darn good to that sound.
Just put one hell of a smile on my face!!!!
When I was working as a locomotive engineer I had a sw-1200 switcher that smoked like that and asked the Enginehouse foreman if he could check it out, he did and all 12 cylinders on the 567C engine had 645 D injectors installed on all the cylinders. Three weeks later with the correct injectors installed she stopped blowing black smoke. I suspect that SD-9 has the same problem. It is not uncommon if you have a bad injector on a 567 to use a 645 injector to get the engine back in service.
The Enginehouse foreman replaced all 12 injectors after the locomotive got 5 smoke citations from the town police..
Turns out the oil company that had the contract to fuel that engine accidentally fueled the engine with number 5 fuel instead of number 2 fuel and it was at an outlying yard and it was fueled on a Saturday and it wouldn't start on Monday due to solidified fuel in the tank and fuel injection lines so to get it running they had to replace all the injectors with 645 injectors as they didn't have any 567 injectors available. They fired her up with a portable fuel pump pumping from a 55 gallon drum the turned the fuel heater on and 24 hours later the oil company was able to pump out the fuel tank and refill it with number 2 fuel oil. This happened in July. The oil driver was new and filled his 2600 gallon tank from the wrong rack with number 5 fuel which is heated to 165 degrees so she ran fine until she was shut down for the weekend. Not having any steam available they used a portable steam generator pumping 200 degree hot water into the engine block after it was hauled back to the fuel pad in west Springfield to liquefy the fuel in the injection supply lines. The Enginehouse foreman was very unhappy with the oil company that made the fueling error. Number 5 fuel oil isn't refined as well as number 2 fuel oil so the injectors had to be replaced.
James Shanks.... good story.... but, since when do local cops have the jurisdiction to write ANY kind of infraction tickets to a railroad?.... and where did that happen?
@@Romans--bo7br The EPA is a thing. Who do you think enforces laws?
@@pootispiker2866.. Local cops Do Not have the authority to sight and write the railroads (of ANY Class.. 1,2 or 3) on ANY violations. The Railroads are under the overriding authority of the Federal Railroad Administration (FRA), Only.
Any such "emissions" violations with regards to the railroads is directly between the EPA, and the FRA... which then contacts the "offending" railroad and investigates it.
Locals (at any level) can contact the nearest EPA office in regards to what they "think" is excessive, then that office, may.. or may not choose to contact the FRA who will then look into it.... "sometimes" with an EPA representative, present.. depending on the situation.
@@Romans--bo7br bro you took literally one sentence and ran with it lol
@@pootispiker2866.... Ya like how I did that.. huh? lol Have a great weekend. : )
I see lots of comments about the engine hunting. The poster says that they are pulling a heavy cut up a hill. This is likely causing the unit to slip. Locomotives have wheel slip correction circuits. I don't know how much this was upgraded when DMIR rebuilt them. Originally they were pretty basic. In short, the power is reduced when a slip is detected. This reduces the load on the main generator, which would make it easier for the diesel to turn. Since each throttle notch is governed to a certain diesel RPM, the governor gets a signal from the load regulator to reduce the fuel rack setting.
When the slip is recovered from, the load regulator increases the field on the main generator, which makes it harder to turn. This is why the load regulator also signals the governor to increase the fuel rack setting. Sometimes faulty wheel slip circuit components can cause this, but based on the description, I'd say that things are working the way they are supposed to.
Wrong, actually. This isn't wheel slip as the changes in engine speed are too slow for it to be slipping. In this video, the "surging" is caused by the governor telling the load regulator to reduce the output due to the engine being overloaded, and that load being dropped off. The engine speed then recovers to the commanded speed. While I believe that the load setting is too high, it appears that the unit was operating for quite a long time and hasn't hurt anything.
When the rack is at too high of a position, with that position being full rack, the governor tells the load regulator to back off the excitation to reduce load. This is a fairly lethargic process compared to wheel slip and the changes in engine speed is too rhythmic to be slips.
The reason it stops when the engine is throttled down is that EMDs have pre-set power outputs for a given notch. The power output in lower notches typically isn't enough to bog down the engine in any meaningful way
Great sound
I call that the "Git 'r dun" sound! But these rebuilds didn't have a true/pure 567 in them as they were rebuilt with 645 power assemblies.
Man I died and went to heaven!!!!
FANTASTIC!!!!!!!!!!!!!!!!!!!!
Sweet sweet music to my ears 😎
Man, 567s sounded strange.
These 567 C blocks have 645 power assemblies installed in them and they sound different but idle and have the same rpm
She smokes real good!
Well that was a nice 4 min video of exhaust.
that explains why the emd engine was smoking and the engine was revs up then revs down and sounded like its in trouble
From what I could see, it didn't "seem like" the trailing unit was working at all.... there was absolutely zero engine exhaust heat signature coming from it whatsoever.... which is probably why the generator on the this lead Geep, was loading and unloading so much. Also, he was "Shoving" the cut... not "pulling" it... which can also make a difference in how it responds with it's tonnage and gradient.
Now that's a view! :)
no turbo. no charger. da girls on her own,,
what's the grade on this track?
That Alco ain't helping.
Smooooke on the waaaater!
Its smoking quite a bit. What causes that?
Bad, mismatched, or incorrect injectors. Could be a plugged air filter, bad load compensator/governor/DC generator, or traction motor going south
Those engines are not running correctly. They are not supposed to surge and smoke like that.
South Shore of What ??
My dude, Travis, that is 804, not 814.
Para que fazer isso?
ITS BECAUSE THE OTHER UNIT ISN'T DOING ANYTHING! ITS DOING IT BY ITSELF!
Fred, the 7042 was being controlled by Engineer Hester. You just cannot hear it over 814's noise.
Also i only see smoke coming out of 814!!!
+Fred Lohmann 7042 has always been a cleaner runner. They are both online and shoving.
I saw a puff or 2. It was helping as well.
Needs a turbo to take care of the over fueling and smoke
@Joe Madej Just saying. There is something seriously wrong with that locomotive to be cycling like that up and down.
Tom Christman It’s doing what it is supposed to. Apparently it is pulling a heavy train. When the wheels slip on the rail, wheel slip prevention and correction circuits reduce power to the slipping wheel. As the slip is corrected, the system attempts to reapply full power. This is done between the wheel slip system, load regulator, and governor. When the wheel slip says that the slip has been corrected, it sends the message to the load regulator for more power. The load regulator tells the governor to increase fuel to the diesel engine so it doesn’t stall under increased load. The governor opens up the fuel setting to the injectors. It momentarily sometimes over fuels the diesel. Later in the clip it sounds like the engineer throttled down. At that setting the unit slipped less. You can hear that the engine was running steady. There are times when the diesel hunts like this. Often it happens when the fuel filters get plugged. In this case the slow speed, heavy throttle makes me think that the locomotive couldn’t hold the rail. I’m not sure if this locomotive had its wheel slip circuits updated in its rebuilding. It originally would have had a relay based system. Now there are aftermarket electronic systems which are much better at holding the rail. They would make this locomotive much more capable than it was.
@@brianburns7211 Perhaps, but with the regular pattern of smoking then letting off, I'd say there is something wrong with the regulator. And with the amount of smoke being produced, the fuel filters are not plugged. Maybe plugged air cleaner. But-they don't seem to care much for that 645NA.
Tom Christman There may well have been a fuel or air delivery issue. I based my opinion on the situation. Obviously the train was moving slowly, and the locomotive would be producing high tractive effort at low speed. That would make any imperfection in rail conditions produce slips. I’ve run lots of old SD9s when I was an engineer for BN. The wheel slip systems seemed to drop load drastically. Running these showed how well EMD improved wheel slip correction especially with IDAC, WS10, and Super Series.
Maybe when DMIR updated the units to SD-M, they got a more advanced system, but I’ve never been on one to see.
@@brianburns7211 anyone implying that the train is slipping is spreading misinformation. The governor is doing its job by not allowing the engine to become overloaded as far as its calibration is concerned. Slipping would cause far more more erratic surging.
What kind of engine dose it have
EMD two stroke 16-654
floodedcar123..... he meant a 16-567 (16 cyl. x 567ci per cylinder / 8.5" bore x 10" stroke) either A or B depending on how they originally configured the prime mover. The major difference between the two is that the 567A was designed for separately mounted accessory equipment while the 567B uses an engine mounted strainer box to service the scavenging and main lube oil pumps.
16-567c
@@Romans--bo7br I think that he meant to say 645, but transposed the digits. They probably got 645 power assemblies, as most railroads did this because of dwindling 567 parts, and parts commonality with the newer power like DM&IR SD38 fleet. They may have gotten 645E crank cases in place of their 567C or D. The D would be if it was rebuilt from a SD18.
@@brianburns7211... Hello, Brian.... thanks for your reply. Yes, that's a good possibility... and very true of DM&IR's program. Wish we could go back to those earlier years in this country..... things were a LOT "saner".
Appears to be a bad load controller or a dc field interruption somewhere in the traction motors. The prime mover is not happy I guarantee that.
THATS WHY IT IS HAVING PROBLEMS!! THATS WHY ITS MOVING SLOW!
It is not having problems. It was doing exactly what it is supposed to do. We were shoving a large cut of cars up a steep hill.
Exactly, SD9m on her knees and shoving with all shes got! Go watch videos of BN's Crawford hill back in the 1990s, SD40-2 and C30-7s dont do it any better. Nice classic EMD roar!
Please stop making assumptions.
