It’s a shame that UP retired and scrapped 8204. She should have been donated to a museum and restored to her original EMD Demonstrator colors.

She was a piece of shit lmao. Of course it sounded great. But from a company standpoint, it’s better to get rid of faulty products. You’re lucky you even got the SD9043’s instead of frames being outright retired.
Why are so many of y'all freaking out about the sound? It doesn't sound like a "GE," it sounds like a four stroke because it is a four stroke and GEs, of course are also four stroke and are bound to have a sound signature not unlike this 265H engine. And at that, it's particular sound signature (four stroke or not) is unique to that of GE or ALCO. The 265H has its own sound. Unfortunately, the 1010J which is an upgraded version of the 265H has been made almost completely silent due to EPA Tier-IV emissions components so it doesn't matter anyway.
People are dumb plain and simple. Some wouldn't even know the difference between an EMD or a GE in the first place. I've heard many different diesel engines in my lifetime so unless you know what to listen for or look for most people wouldn't have the slightest clue.
@@losi5ivet29cc just cuz people dont pay attention to every single small sound detail in an engine doesnt make them "dumb". as said, most EMD engines sound like a vacuum while GEs have a more deep and chugging sound. this one sounded similar to most GE prime movers. not every diesel engine in the world sound the exact same as others.
@@thedwaynerailfans my people are dumb comment was pertaining to the fact that the vast majority of society is usually ignorant to the things they do not understand nor wish to comprehend. There's a lot of fans out there whom are simply misinformed or misguided in a subject as well. I can keep going on and on. My point is people like myself who are passionate about certain subjects whether it be trains planes or automobiles usually research and try to get as much information as they can about it whether it's reading books magazines or in today's age online or actually if possible going and seeing the real thing in person. My diesel comment was to say I've been around a lot of different diesel engines and can usually tell what they are from a distance just from sound alone. For example a 2 stroke Detroit definitely has its own unique sound but doesn't sound anything like it's 4 stroke replacement the 60 series engine. 60 series have often been mistaken for CATs due to their low guttural growl but if you spend enough time around them you can quickly learn how to tell them apart. The same can be said of EMD and GE as well. Hopefully that makes more clear?
This is the very first time that I hear 265H's sound. Definitely sounds like a GE or ALCO, but sounds more powerful. I am a fan of EMD 2-stroke, but I really love this sound. A bit pity for me that EMD's new 1010 is pretty much a quiet engine, but maybe a good news for engineers that drive them.
The 1010 is the same base engine (block I guess you could say) as the 265H. It is just an improved version. Think of it like the Honda J series engine family. Back in the early 2000s we had J30s and J32s. Now we have J35 and J30AC and so forth. The reason the 1010J is so quiet in comparison is due to the exhaust emissions scrubbing equipment. Also, if I'm not mistaken, new regulations have required newer locomotives to be far quieter because even noise pollution is a thing now and perhaps more importantly, crew health and safety regulations require less average decibels to prevent damaging hearing loss... so on top of the exhaust catalyst and DPF, I do believe there is an exhaust silencer. Also, the new traction alternator and AC drive inverter are extremely loud for some reason. Between induction noise for the turbos, the inverter, traction motors, new traction alternator, exhaust equipment, exhaust silencer, and even sound reading material in the long hood, you can barely hear the engines in these units unless you are literally in the cab. If you took all those new technologies off, it'd sound just like this test mule unit in the video. Oh, and even the fuel injection system and fuel pumps are so loud on these new units that it also contributes to drowning out the natural engine sound. I do think that these new units are cool though, and while I will miss the 710G dearly (it is and was my favorite prime mover, sounds incredible), I can totally understand the move to quieter locomotives. Even as a railfan, living near to mainline tracks (and even later on over a mile and a half away) you can still hear very loud locomotives and it is very intrusive. In railfanning, you don't mind it because that's what you're there for, but as free the 150th time a train passes when you're living by th tracks you realize why quieter trains are a necessity. Even quiet they are still cool. Plus, electrified trains (catenary) are even quieter but are still very cool to me. I bet you that at some point in our lifetimes the US rail network will be electrified. It just makes sense. (Not that I want that, diesel-electric is still way cooler to me personally).
@@scenicdepictionsofchicagolife I've watched several videos about 1010J's idle. I also checked it out the one in your channel, sounds the same as other ones I have watched. I feel they are even quieter than GE. Currently I am curious about how 1010J sounds like in notch 8. I never find a video with clean sound, there always a GE or 2-stroke EMD and other noise like horns and bells going along with, they are so quiet that they sound like in DIT status in the consist.
@@scenicdepictionsofchicagolife Yeah, fans always have different hobby from public. Actually electric locomotives can also be loud monsters, even louder than diesel. Their fans, inverter, transformer and IGBT unit can also generate loud noise.
Even though it is a 4-stroke, there is still EMD unique growls lay there if you hear it more by headsets or earsets or anything albeit a bit quieter. The low and heavy bass sound of the engine is still in fact, identifies this as an EMD not anyone else.
@@CentralJerseyRailfan I've played around with the loksoftware enough to somewhat know what I'm doing but when it comes to creating new sounds etc I don't actually know how to do that I must admit. Basic programming and sound changes I can do but creating new ones is still a mystery to me? I believe someone should make a video on how to create their own sounds.
Never heard a 265H before. I can't say I'm thrilled with the noise. The idle governor has a horrible romp in it. By the time they work it up to rated power it sounds like it's going to tear itself apart. I sat through a presentation by EMD's chief engineer about the new 265H engine back around the year 2000 and thought it to be interesting. Was surprised to hear the engine was a failure in the field a few years later. And now they've developed it into the 1010, but can't get customers to buy it. Stick with the 2-strokes.
EMD's two stroke series became a thing of the past... Caterpillar is EMD's parent company and also owns PRLX. General Motors sold them,then came Greenbriar Berkshire,and then CAT/PRLX. Even though there is thousands of EMD units still present in Class 1 usage,they are greatly being phased out once their years are done in comparison to GE units and aren't compliant with these modern regulations.Less of the modern EMD units every time are getting rebuilt while GE rebuilds are starting to surpass. The problem with the 265H's was zero harmonic balancing which is why they had aggressive internal vibration and were literally ripping and tearing apart crankshafts,motor mounts,and any other critical components.The 265H's later on were improved and modernised but only saw prolonged usage in Asia,China,and India along with the alternative motors such as the 210H's that are still licensed under EMD. Caterpillar completely rebuilt the 265H's as the 1010J's in the SD70ACE-T4's as you've already said.The major differences are the fuel injection and crankshafts which needed correction.They even manufactured alternative versions of the same engine as the C280 in other apparatus. The 265H's were the only and last ever four stroke motors built by EMD and it was the only shot they had at staying in the market to meet emissions testing. The SD9043MAC convertibles were already debuted while EMD was still developing and rushing the 265H's.Only certain amounts of the SD9043MAC's in total from Union Pacific and Canadian Pacific were even converted and all within a few years if not less were scrapped or returned as EMDX units. The SD9043MAC's remained in service until their frames cracked and some of them from CEFX were on leases. There was 60 SD90MAC H2's from Union Pacific with four of them from Canadian Pacific.Most of them were also scrapped but some survived as exports to Australia to BHP Biliton. The SD70AH-T4's ironically were failures as well.Union Pacific purchased 90 of them while CSX ordered 10.They were primarily based on the prototype SD89MX which at best was ever leased to BNSF and remains today at CAT/PRLX as a testbed unit only.BNSF,KCS,and Norfolk Southern also had requests of SD70AH-T4's but canceled them.
@@bkayganich Yes,recently they finally got rid of the hunk of junk ST70AH-T4's not that long ago and gave them back to PRLX.Those units including the other PRLX SD70AH-T4's have ended up on leases to Ferromex and are currently in Mexico. I honestly never understood why CSX sold all of their SD70ACE's and even purchased the handful of those SD70AH-T4's,because look what happened now.Those SD70ACE's still had alot of usage left in them and are far more reliable just any other units than the tier four units.
It's a shame that Caterpillar shuttered the GM Diesel Division in Canada, Train crews all over North America still say that the quietest Cabs came from London Ontario 😢
maybe i am an odball but i think most rail fans and even just diesel engine fans would pay to hear this in person . like have a yard full of old trains that you load test for show every day. i would visit that rail museum stay all day and pay 100 entrance fee happily .
China gets all the best toys . would love to hear one in person but its a long way to go. its amazing to think such an american engineering project passing through london and then finding its destiny in the far east
If only there was a Tier 4 EPA 2015 compliant version of this engine for 6000hp then it would have been running on KIcking Horse Pass Lake Louise to Revelstoke Route Sand Patch Grade Sherman Hill Horseshoe Curve
The motors you're unknowingly mentioning is the Caterpillar 1010J's in the SD70AH-T4's that are literally based on the 265H's from the SD90MAC's. Caterpillar actually changed the fuel injection and redesigned the crankshafts for the J motors which on the H motors was one of the main causes of failures due to poor harmonic balancing. However,the units are straight junk.There is 90 SD70AH-T4's only in usage under Union Pacific while the PRLX SD70AH-T4's are being leased to Ferromex in Mexico.CSX finally gave back their 10 ST70AH-T4's to PRLX. Norfolk Southern,KCS,and BNSF had the demonstrators and leased units several years ago but canceled any orders.
They had to redesign and add more material, I think the redesigned engine version weighed in about 10,000 lbs heavier and this resolved piston issues. Computer control was not well designed for a lead locomotive but they seemed to do quite well as DPUs or second units. In the end, the use of 6000 hp in a car body was not practical for the railroads.
The SD70ACE-T4 is powered by the 1010J, which is an updated version of the 265H in its 12 cylinder version, and not the QSK95. To my knowledge, no freight railroads are using the QSK95. Only the passenger locomotives such as the Siemens Charger units are powered by the QSK95.
It's a pity my Athearn Genesis FMG SD90MACH doesn't sound half as good, even with the standard (useless) sugar cube speakers replaced with a high bass speaker. But it would take more than you can shoehorn into a HO scale model to reproduce these sounds.
Wow, surprise- a 265H sounds like a 265H. Listen to the ESU recording and compare it to this, there's obvious differences. Larry Broadbent is a noted Canadian photographer and engineer, I *highly* doubt he'd resort to using ESU sounds over photos he took of an SD90MAC demo at the factory.
First time I encountered a pair of these in UP paint, I couldn’t get over the…..”interesting” sound of those prime movers. It did NOT sound anything like the typical turbocharged EMD 645 “purr” I was so used to. They sounded about as crappy as they were physically. Complete junk.
That's because it's NOT a 2 cycle (thank you - EPA!!! Not!!)..... this one is the "new & improved" 1010J engine, that is the seriously upgraded version of the 265H.... which was plagued with piston issues. as well as computer control issues... especially when positioned as a "lead" unit.... they were fine in DPU positions, other then the ongoing piston failure issue's. They've resolved all those issues, with the new 1010J prime-mover.
We had 4 of those on our UP grain train out of des moines iowa headed to kc and 2 died south of Trenton Missouri and we couldn't make the hill up into polo. Went dead right there. Total junk these locomotives were. Electrical issues out the Wazoo
I think the point is, nobody is interested and nobody wants these locomotives. There is nothing interesting about railroads anymore. Might as well put more trucks on our already congested highways and freeways.
This is the ALCo 251 resurrected. It's beautiful. God I wish the 90-H's were successful. This is an amazing sound, better than even a U-boat.

maybe i am an odball but i think most rail fans and even just diesel engine fans would pay to hear this in person . like have a yard full of old trains that you load test for show every day. i would visit that rail museum stay all day and pay 100 entrance fee happily .
EMD 265h sounds=tractor working in the field
nope that’s EMD SD89MAC had these 4 strokes a while back, some early SD70ACe, had em on the test bed EMDX 90-92 test unit had em also
Just uploaded a video of one of these beasts to my page too. Good stuff!!
It sounds a bit different from 265H engines on JT56ACe (HXN3), more like GE.
That chug resembles the ALCO
Whats is diference in 265h and 1010j??
1010J is more quieter
China gets all the best toys . would love to hear one in person but its a long way to go. its amazing to think such an american engineering project passing through london and then finding its destiny in the far east
If only there was a Tier 4 EPA 2015 compliant version of this engine for 6000hp then it would have been running on KIcking Horse Pass Lake Louise to Revelstoke Route Sand Patch Grade Sherman Hill Horseshoe Curve
GE has a 6000-ish HP GEVO engine for international markets
The motors you're unknowingly mentioning is the Caterpillar 1010J's in the SD70AH-T4's that are literally based on the 265H's from the SD90MAC's.
Caterpillar actually changed the fuel injection and redesigned the crankshafts for the J motors which on the H motors was one of the main causes of failures due to poor harmonic balancing.
However,the units are straight junk.There is 90 SD70AH-T4's only in usage under Union Pacific while the PRLX SD70AH-T4's are being leased to Ferromex in Mexico.CSX finally gave back their 10 ST70AH-T4's to PRLX.
Norfolk Southern,KCS,and BNSF had the demonstrators and leased units several years ago but canceled any orders.
What were the biggest problems with this compelling prime mover? Was it rushed into production too quickly? Can the Cummins QSK95 save Progress Rail?
They had to redesign and add more material, I think the redesigned engine version weighed in about 10,000 lbs heavier and this resolved piston issues. Computer control was not well designed for a lead locomotive but they seemed to do quite well as DPUs or second units. In the end, the use of 6000 hp in a car body was not practical for the railroads.
Progress rail is a Caterpillar company. A direct competitor to Cummins.
@@markrhuett Interesting, since it's the QSK95 that's the power plant in the SD70ACe-T4.
The SD70ACE-T4 is powered by the 1010J, which is an updated version of the 265H in its 12 cylinder version, and not the QSK95. To my knowledge, no freight railroads are using the QSK95. Only the passenger locomotives such as the Siemens Charger units are powered by the QSK95.
@@christopherstephans3383...... Where did you Ever read That "Fairy Tale" ?!?!?? Lol The Imagination of some people's children!!!.... Incredible.
She’s got chop
It's a pity my Athearn Genesis FMG SD90MACH doesn't sound half as good, even with the standard (useless) sugar cube speakers replaced with a high bass speaker. But it would take more than you can shoehorn into a HO scale model to reproduce these sounds.
It’s like an EMD and a GE had a baby
I like the sound of the two-stroke much better.
I'll "second that" Sentiment!!
You had a cool job....
Love it a runner
Did you use the sound from ESU Loksound database?
Haha I don't think so.
@@fzttwd Haha okay. I guess it would be more realistic if you recorded the actual loco on video
Yeah i agree, the video is obviously still pictures, kinda sounds like the loksound file 🤷🏻♂️
Wow, surprise- a 265H sounds like a 265H. Listen to the ESU recording and compare it to this, there's obvious differences. Larry Broadbent is a noted Canadian photographer and engineer, I *highly* doubt he'd resort to using ESU sounds over photos he took of an SD90MAC demo at the factory.
Its a bit strange how a V16 can have such a choppy exhaust note
It’s because of how low RPM these railroad Diesel engines are.
It's because these run at very slow rpm
Sounds like a ge and emd hybrid
Not much whine without that gear driven turbocharger
Is that actually what it sounds like?
yea this is literlly it
Mechanical music !
Sounds like alco DL506C
I recorded an MBTA train doing that
The loco should have been fitted with prime mover emd
It IS an EMD prime-mover..... the 1010J 4 stroke.
That time EMD made an Alco 244 and it ended up being even worse than the original somehow
Not sure what kind of drugs you're on... but it's REALLY messing up your brain cells!!
@@Romans--bo7br its true, the 265H is just a worser 244
I say the four strokes sound better at idle, but I hate how they sound when they throttle up. Emd sounds better at throttle.
You mean the EMD 2 Cycles sound Much better in ANY Notch!! This IS... an EMD, only their New 1010J 4 cycle.
First time I encountered a pair of these in UP paint, I couldn’t get over the…..”interesting” sound of those prime movers. It did NOT sound anything like the typical turbocharged EMD 645 “purr” I was so used to. They sounded about as crappy as they were physically. Complete junk.
Your confusing the original "265H" prime-mover, with EMD's new "1010J" engine. Either way, personally... I'll stick with the 2 Strokes!
this does not sound like emd two stroke engine at all more like 7fdl 16 cylinder...
That's because it's NOT a 2 cycle (thank you - EPA!!! Not!!)..... this one is the "new & improved" 1010J engine, that is the seriously upgraded version of the 265H.... which was plagued with piston issues. as well as computer control issues... especially when positioned as a "lead" unit.... they were fine in DPU positions, other then the ongoing piston failure issue's. They've resolved all those issues, with the new 1010J prime-mover.
bet those people in london question why it was so big 🤣
London, ONTARIO.... Canada!.... NOT London, England.
Such a shame when they scrapped a lot of these because of the crappy prime mover. They could've at least installed a 710.
The funny thing is? The 12 cylinder version of the 265 engine proved to be far more reliable than the 16 cylinder version used in the SD90MAC.
@skeezix91..... That is exactly what EMD, did.... the swapped in.. the 710 series prime movers.
Oh, so they just took the engine from a GE locomotive. I see. Just rebrand it, and you have a perfect 7FDL I mean 265H engine.
I still cant believe emd put alco engine on the sd90s
Sound Similar Amtrak GE Genesis engine
something is not right here....
Boy that sounds mean should've named it mack an put a bull dog out on the nose👍👍👍👍👍
Motor de 4 tempos é bom, mas prefiro os motores de 2 tempos.
We had 4 of those on our UP grain train out of des moines iowa headed to kc and 2 died south of Trenton Missouri and we couldn't make the hill up into polo. Went dead right there. Total junk these locomotives were. Electrical issues out the Wazoo
I think the point is, nobody is interested and nobody wants these locomotives. There is nothing interesting about railroads anymore. Might as well put more trucks on our already congested highways and freeways.
