They cost more, but they were supposed to pay for themselves with reduced fuel costs. But they proved to be a reliability issue because you had three times as many engines to maintain and the engine and generator did not use standard parts.
Also, engineers did not like them because they were slow to get a cut of cars moving. They were supposed to be designed for switching work, but that requires a lot of back-and-forth movement, which requires a lot of stopping and starting. They didn't start as fast as the old road-engines handed down to yard work engines did. Norfolk Southern considers them an experiment that failed. [NS, p16 (This Norfolk Southern Powerpoint presentation also has graphs displaying the EPA's Tier requirements.)] This 2014 presentation indicates that only one Class I railroad is still buying gensets. This photo clearly indicates that BNSF is not buying them.

Was involved in a Accident between the 2014-2015 year and Ran head into a Loaded tanker and Blew up into flames
(At least that's what everyone told me)

William Brown This one ran over a draw bar at
Alliance, TX punctured the fuel tank and
burned up within 200' of the Hump Tower.
Meanwhile, companies have learned how to rebuild the old 4-axle units with a single engine to make them economical and clean. For example EMD710ECO Retrofit Kits and Knoxville Locomotive Works.
It is particularly important to cleanup the locomotives used in yards in urban areas because when the study was finally done, a direct correlation was found between kids having asthma problems and the home's distance from a major railroad yard. (BNSF's Clyde/Cicero Yard was the specific yard used for the study.)
NS is also experimenting with a natural gas mother/slug set where the slug is full of high pressure tanks. They are also working on battery powered locomotives. They are on their second iteration of battery design, but they still need to do more R&D. [NS, p21]
Canadian Pacific's trail of two NRE gensets compared to GP9s indicated the crews liked them, but there were still significant reliability issues. The report mentioned that they did not have automatic start/stop. I wonder if NRE removed that feature to address the complaints that they were slow to get a cut of cars moving. They could at least do what I thought of when I first read about gensets --- install an active/inactive switch. The engineer knows if the locomotive is stopped for a short period of time because it is changing direction or if it is stopped for a long period of time. Leave the engines running for short (active) periods and shut some down for long periods. When the switch is turned from inactive to active, fire up the engines then so that they are ready to load when the throttle is pushed.
Duty cycle charts for line haul vs. switcher locomotives show why it is so effective to reduce emissions during idle and low power ranges for yard engines.

Different looking locomotive.... any idea on age or series? Taken in Northlake, IL
Jason Chadourne it's a genset
Bruno Berzins RP20SD. Paired with an SD40-2 so actual work can get done.
Harold J. Krewer John, it's a genset built on the frame of an old SD40-2. Had been one of UP's "Fast Forties" (8001) in a previous life. Originally built as Yoo-Pee 3241 in 1973.

The Not-so-loved 200 series Belt Railway of Chicago Gensets resting inside the Engine house at Clearing Yard in Bedford Park. Taken February of 2016.
I will note that the Shop itself for being the age that it is, Is well maintained and kept relatively clean.Daniel Herkes Perhaps unloved, but the ability to de-rate a power unit and save fuel and engine hours is the future.
Steve Kraus Against added maintenance of more engines, generators, etc. It's a tradeoff. It's not like a big prime mover is putting out full HP all the time; it too is "derated" by running at reduced throttle. Perhaps there is a fuel savings by the small engine running at max throttle as against the big engine at partial throttle but there's no such thing as free lunch. Time will tell.
Daniel Herkes The smaller engines can be pulled out and shopped very easily. Those big guys have to be serviced in situ. Since the prime mover is only running at full capacity for a small portion of the time, and the small gen sets can be turned off (they are not wearing out if they are off) when loads are light, the modern design will be successful in the right environment. The shortest, cheapest path will always prevail in a transport problem, and not to take it is ruinous.
Justin Gillespie Which is why almost every railroad is getting rid of their gensets, not practical.

How many Gen Sets does it take to move a train. Or............I heard the power desk was short some motors but this is nuts. No April Fools here, 6 Gen Sets being moved to Barstow, CA on 4/1/19 wb into Flagstaff, AZ on the Transcon.
Alex Bieniek They have 3 700 horse power Cummings in each Genset. It’s equallying to 2100 horse power.
Rupert Gutierrez Don't know if those genset units came from the dead line at one of Ft Worth,Tx yard,cause I saw some on my last trip.
Michael Thomas Headed for the scap pile.
Barry Sprofera Is that a question or a statement?
Michael Thomas Barry Sprofera statement...BNSF's talking about getting rid of theirs, like UP did.
Blair Wallace Probably four “jacks” in power the trailing six either DIC or DIT
[DIT means Dead in Tow. I don't know what DIC means.]
It takes two locomotives to shove three cars?! I guess so because when they went across the road, they had four of the six gensets running at 2:23 (vv^+^^^). At 4:10 we see the guy running the remote is not strapped to the handrail. So he is violating the "three points of contact" rule. I'd be willing to count his rear resting against the hand rail if he had enough room to lean against the rail. If anything, it looks like the rail wants to shove him off the platform. With just one tank to push, they were using ^v^+vv^ gensets. Using 3 gensets (2100hp) to push one car seems like bad fuel efficiency. For relatively modern locomotives, one of the engines is smoking real bad.

Came across this string of UP Ultra Low Emissions Genset Switchers near Compton overpass close to where the old MoPac shop used to be located. Downtown St. Louis skyline in the background and the Ewing Metrolink yard and shop just passed the Switchers. That is where I worked my last 15+ years as a LRV operator of my 33+ years for Metro Transit.
Dennis DeBruler Are they in storage? I've read that gensets are viewed by the Class I railroads as an experiment that failed. But I've not been able to determine what the problem was. It sounded like a good idea on paper.

The end of the Genset era on BNSF was evident at Nowers Yard in OKC yesterday, as a long line of NRE-built 3GS21B units rests while awaiting their fate in the shadow of the Oklahoma Capitol building. They were purchased for use in Texas with an anti-pollution grant that required at least 10 years in service. This is year 11.
Curt Boyer Did they have the three truck engines in them? Or what made the power?
Mike Moroni three Cummins QSK19C I6 engines.
JC Walker UPRR had them at auction a few years back and they sold around $65,000 each.
Kevin Shockey The only thing worse then the Genset (exploding choppers) was the Green Goats (exploding batteries).
Noe Gutierrez So would the Gensets have been better performers with more reliable engines, or was the whole operating theory faulty?
Richard Stewart Great question, I always thought Gensets were a good idea.
Brad Butcher I wonder that too, I think the gensets and green goats are unattractive. But I have not heard specifically what the complaints are about them.

BNSF genset switchers working in Saginaw TX on 20101018.
John Shelton Does 4 are now siting in okc in deadline now.
Ronnie McCallay John Shelton, I sort of thought they might be in deadline somewhere now, which is exactly why I posted the photo, hoping to get updated info. Thanks for providing it.
Dan Hildebrand I understood with 3 motors in each the costs of maintenance was extremely high vs an old GP unit.
Rupert Gutierrez BNSF got a dead line of NRE genset unit at the North yard in Ft Worth by Blue Mound Rd.
|Screenshot, and some more in his second video|
Jacob Rajlich I believe that a lot of these are set to be scrapped. These units had been stored across the system and all moved to Galveston in the last few months. I see the ex-ATSF C40-8W’s, and I know more 70MAC’s are apparently going to meet the torch here soon. Plus the Gensets which have been laid up for a good while already.
Greg James There is a similar collection just east of Gillette, Wyoming from when coal took a dive in the Powder River Basin.
Reggie Bass How did the Gensets end up on the dead line so quick, they are THAT old?
Mark Gillings The are laid up for sale.
Mark Gillings They aren’t old, they’re unreliable.
Reggie Bass Mark Gillings fill me in what was the main issue? Constant maintenance, couldnt pull, enviromental issues.
Mark Gillings From what I’ve read maintenance was an issue and from locomotive engineers, just not too powerful. Seeming like the kicking-on of the next genset lagged behind the demand for more power.
Most likely, their length of time in service has been met by the requirements of their funding and they are now disposable.
[As someone asked, then why are they parked in the salt and humidity of Galveston given that BSNF is also in Arizona and New Mexico?]
|safe_image for Loads of locomotives light up Harborside Drive in Galveston[BNSF has so much land there that the port authority covets some of it.]|
Davis Morton Those were mostly all there in October when we were down there.
Dwight Thompson shared
Bob Thompson The GEs are.worn out, and the Gensets are crap.
Ryan Schaufenbuel Even IANR got rid of their gensets and leased back GP38-2s...
John Scott I’d exclude the Gensets from the count because they were retired due to them being such a disappointment.
Zach Petersen Dash 8-40CW and SD70MACS as well which is sad.
Dane Tibbetts They still run the gen sets. See them all the time at strang in la portet. [I have no idea where "strang" is.]
James Lee Stewart On the other side of the coin there are lots of trains running and they seem to
Be well powered ! I live on the BNSF in Illinois!
Mike Anderson Lmao most of them are gensets.
Scott R. Conforto I see a lot of gensets which are junk.
Thomas Maley How many gen sets are parked there? It looks like a lot.
Ryan Schaufenbuel Every one they owned I believe.
Steven Spaziani What's sad is my RR says they don't have any engines to replace the one I'm using, it leaks and blows oil out the stack, we have to wipe it down every couple days, but without it we serve our customers. Also this engine was blown in for the same shit 3 months ago it was sent for repair but we all know it just goes to another terminal because repairing costs money and railroads hate spending money on repairing older locomotives. It's also sad that the builders don't make 4 axle locomotives any more and have not built a 4 axle switcher since the 80's.
Brandon Klopp Steven Spaziani we have a 4 axle yard goat over in Chicago, heard it was built in 2015.
Update: The code for the "v" and "^" is, from the beginning of a train, a genset is not running (v) or is running (^).
A video of v^^+^vv pulling 12 cars. So UP is still using them in California. (They were invented by NRE as a solution to meeting California's pollution requirements.)
A video of 1) ^vv+vvv+vv^ pulling two cars (street running), 2) vv^(barely)+vvv+^^v pulling 10 cars, and 3) ^v^+vvv running light.
A video of gensets switching tank cars of corn syrup for a Coca Cola plant. A reminder that there are 140 calories in every 12-ounce can. This video is hauling ADM tankers instead of Corn Products tankers to the Coca Cola plant.
NS is auctioning three of their gensets.
UP had a couple running eastbound to Kirk Yard at Griffith. The third engine at the end of the long hood is turned opposite of the other two.
IHB was still using them in Dec 2018: Arturo Gross Flickr
