GE 12 Cylinder FDL Load Test - The Universal Series

- During mechanical session we load tested our former Georgia Central/Norfolk Southern/Southern Railway GE U-23B #3965. I took advantage of this to record the audio from it. You can hear as the load picks up the engine exhaust gets louder gradually. The load is routed through the grid resistors for the dynamic brake to have self load. We run through all 8 notches of throttle in this audio. Enjoy!
Who doesn’t love that 4 stroke chug?
No one!
Aaron K That’s the same engine that is used in the P32AC-DMs
@@metronorthrailfan2244 the P32-8BWH uses the same 4 stroke
@@jmream2618 I knew that. Honestly whenever I say P32 I usually refer to the P32 Genesis
I'm mainly an EMD guy,..but the sound of this FDL engine is starting to grow on me!
Me too! Have you heard the Chinese HXN5s yet? With the 6000hp unmuffled GEVOs? Omg!
See if the P32AC-DM 3,200 hp version of the FDL12 engine grows on you.... loaded with accessories, AC traction, unique cooling fans, a unique turbo, throbbing and chugging with Metro-North and Amtrak trains:

Totally agree , you are describing me sir , especially the old small ones , salutes for your great taste of machinery sound 🎆🎇🎈
@@AUSSIETRAINDRIVER small ones are much nicer and more amusing , greater pieces are so loud and taste less , GE lost it`s taste in sounds in the recent years
great video. GE FDL engine produce awesome sound. In my country we hear this sound every day, because there is a lot of GE U series (it uses 7FDL8 engine).
Cc 206
In Kenya we have them. They are known as 93 and 94 class very powerful
Nice!
@@ellisjackson3355 Thanks,,,
Love the sounds of the FDL 12 cylinders, FDL 16 cylinders and the HDL 16 Gevo.❤
Beautiful 7FDL mechanical music! One of the best-sounding GE engines I've ever heard, and boy howdy have I heard a lot of them. Very reminiscent of a GEVO-12 at high rpm's, but GE four-strokes fire similarly, and both sounds great. But nothing beats the classics, those U-boats were some cool locos. The U-boats were way before my time. I'm glad a select few remain out here. Thanks for sharing this load test of one's prime mover!
May Cooper-Bessemer live forever.
I sleep to this every night, but with two of them. Reminds me of my childhood and my favorite GE U Boat: *U50C.*
U50C is awesome. #2 favorite U series here. #1 for me is the U28CG
I could listen to this in a perpetual loop all day and night! 😴
How come these things chug so much but when in GE P32AC-DM locomotives they make a humming sound then start chugging at notch 8
The FDL prime mover went through a series of upgrades from what you hear in a U-Boat/Dash-7 to a Dash9 class unit. I believe on a newer FDL the exhaust has two manifolds coming from the power assemblies while an older one has only one. This would increase the volume of exhaust noise tremendously. A newer FDL uses electronic fuel injection rather than mechanical. The humming noise you mentioned might be the electric fan for the radiators. Older FDL's had all of their auxiliary appliances (Traction motor blower, air compressor, and radiator cooling fan) mechanically driven from the engine. Newer FDL's have all of these appliances driven by an AC electric motor which is powered from a companion alternator attached to the same rotor as the main traction generator.
1:35-1:46 1:43
This reminds me of rail fanning on Conrail's Boston Line. On the weekends they would take the U23B?B23-7s from all the locals at outlying points in Massachusetts and run them together on a road job back to Selkirk for service. 4-5 of them made quite a sound climbing over the Berkshires.
Como não amar um som desse
I could fall asleep to this..soothing music to my ears....ahhhhhh! I can smell diesel!
Love the sound of the FDL 12!
I love that sound. I recall it when I was a boy at the age of 10 in 1963, when I saw the new Alco C-420 locomotives delivered to the LIRR (Long Island Railroad). They used the Alco V12 series 251 engines, 4-stroke cycle design as well, they were very smokey on acceleration from a stand still which was quite impressive, I even like the odor of the exhaust! My Dad took me to the LIRR station in Mineola, NY back in the very early to mid 1960's. We even saw the final service days of my favorite locomotive, the Fairbanks-Morse model CPA24-5 Consolidated Line of locomotive with the 12 cylinder in-line opposed piston diesel engine, unforgettable and fond memories of those F-M locomotives, the LIRR had five (5) of these 2,400 HP cab units, good times they were!!
1:46-1:56 this part right here is good, and no I'm not trying to be funny. I've heard a gevo cruising down a hill that sounded like this.
I like that sound
This engine could've been used in a train simulator.
This engine has been used in Trainz (TRS)
There she goes notch 8; and 28 pounds boost, I love it
Only 28? Huh didn't know that
U-Boat 12cylinder FDL diesel engine also Gevo 12 cylinder FDL diesel engine
It reminds me of the 16 cylinder version of the GE engine that I would hear years ago in the NYNH&H RR U25B diesels.
I miss that sound of the old FDL engine used to hear it a lot in Santa Barbara until the old GEs got banned from southern California in 1987
Bill Johnston the 7FDL was used all the way up through 2004 in Dash 9 and AC44 units.
P Kranz also Amtrak's dash 8s
@@jmream2618 Yes including the Dash 8-40BP, better known as the Genesis, or by Amtrak, the P40DC.
@@pkranz937 I think what Mr Johnston means is that the old U-boats got banned in SoCal, but I'm not from California so I'm just speculating. All GE's used the 7FDL prime mover from 1956-2004.
Reminds me of when I chased these in their last days on GC. Thanks for posting.
I prefer the 16-cylinder version over the 12-cylinder version, anyday!
Great video friend, I love this sound. Here in Brazil MRS has the U23CA, which use this engine. Would you have some C30-7 FDL16 there? Thank you.
Looking for someone that has expertise knowledge on overhauling GE 7FDL Engines. The overhaul includes replacement of main bearings.
Music to my ears 😁
Very useful when pulling alot of freight and a lash up .
Only thing missing is the engine fire. Not if, only when.
If there's a turbocharger there, it has one heck of an intake silencer!
Gawd listen to those turbos spool up!
This engine sounds just like the new commuter train locomotives in my area. I wonder if it is this engine.
turbo speeds up at 2:00
full throttle maybe?
TC Hesing sound
Sound also same as Ruston prime mover
Motor de 3000 HP
A sound well at home on the L&N & dear to the heart ;D those EMD chants are strangers on a road ruled by GE & Alco power ;D
Why does it sound like one cylinder is louder than the rest? I do like the fact, that it's a turbo-charged 4-Stroke, much more fuel efficient than the super-charged 2-Stroke engines.
I think it is because of exhaust gas pulse synchronicity, of some sort. Whether it is by design ("pulsed exhaust") or accident, I don't know.
2 strokes have the power advantage overall, plus they're simpler in design. Thermal efficiency is where they excel as well averaging upwards of 50 percent.
Sounds good, but prefer that EMD chant. Both engines, get the work done.
Hi guys.Somebody knows some website where I can find technicals informations about locomotive U20C ?Thank you so much.
LONG LASTING LOW RPM
Medium speed engines
Same as raising the RPM's
This is photo or video?
Yes.
sound like a sulzer 12LDA
new zealands kiwi rail uses them in their DX class locomotives, DXC DXB DXR
Load Test. Notch Number 8
Prime Mover - Powe plant
Major glug factor here.
Now that’s some stanky sounding raw power!
That was not a load test, waiting to ship..
Another excellent video !
One can still hear these V-12s . They are employed in the old Amtrak Pepsi Can
U-boats. I hear then quite often as they are used often as trailing units on the Coast Starlight #11 & #14 as they travel through Dunsmuir. AMTK 500 series I believe it their numbers. en.wikipedia.org/wiki/GE_Dash_8-32BWH
Wow
Incrível um super motor
Gevo-12 sounds better
