The whooping is the compressor motor, 3 phase starting up across the line, inrush current on the windings. I work in HVAC and large water pumps (10-100HP) make the same, awesome sound!
@@polhpolh64 Its because the phase currents in big motors are much larger than smaller motors. The noise happens because the phase currents in the windings create a magnetic field which vibratess nearby metalic objects at the carrrier/phase frequency. The stronger the phase currents the stronger the field and the louder the sound.
LITERALLY listening to this in person now!!!! It’s night and I’m in bed by my window and live by a canyon. This noise ECHOS was throughout and sounds soo cool then after this noise I hear more of the engin roar, then it hisses (like it’s shooting compressed air) then next comes the loud ass train horn!!🤣 I love it I noticed the Whooping happens a could of times
So that’s what that whooping sound is. I’ve been wondering what that sound was since I was 9 and now here I am, 19 and I finally know what that sound is
*WE'VE HIT AN ICEBERG!* LMFAO, the starting bells on these Junk-Gevos as I call them sound just like Titanic's watertight door bells. I prefer starting a U50C, U50, and U-Boat Universal Series over a ES44AC any day.
The prime movers are different between these GEVOs and the P42s, but as far as I know most all modern GE locomotives use similar secondary components like air compressors and such.
Diesel locomotives were largely unregulated for many years but the EPA has started enforcing new emission requirements for locomotives starting in 2000. Most new locomotives have been and are still able to meet the standards without DEF even with the new Tier 4 regulations that were effective starting in 2015. EMD/Progress Rail's F125 does require exhaust after treatment and as far as I know it's the only one so far that does.
Probably because most street truck are modifying them to do so. Also they do not weigh 195 tons and 1000 cubic inches per cyl. Full load and hp at 1000 rpm. Most are clean at full song. Unless not loading properly. Added plus they dont idle in front of schools waiting to pick up their kids.
Most modern locomotives have auto shutoff/auto start functions. The ringing is an alarm, and I think it’s usually alerting that it is about to auto start.

I love hearing the whoop sound 😂😂
Me too is the thing that make special the GE like the brrrrrrrrrr of the c130 Hercules
Me three!!
Whoooop

Why do only big motors like that make that bwoop sound i have a 1.5hp motor and it doesnt make that sound

1:35 the best sound of a GEVO!

Love that whoop, too! ❤❤❤
That crank up tho
It sounds so good. GEVO-12s are the best
1:35 whoop!!
I just love the whoop😂👍
1:36
1:37
Literally the best sound ever
GE FANS UNITE
Personally I like the dash 9s better nothing against the gevos tho
Love bnsf
Been there done that thousands of times but it was for the competition
I like train videos on CZcams 👍
So that’s what that whooping sound is. I’ve been wondering what that sound was since I was 9 and now here I am, 19 and I finally know what that sound is
Thanks for watching and I'm glad you finally found out! That sound has been a staple of GE locomotives for years.
Trinity Rail Productions Thanks. I’ve heard it most on the Genesis engines.

The wood reminds of the p42dc

Ear candy
I found out where the compressor is at the fan section
Wow
1:39 Komi-san's sound
You're tripod needs an upgrade.
Haha, I've upgraded several times since then. But this looks like it was handheld
Rumble grumble
What's that banging sound?
Which one?
ok where is the diesel exhaust fluid so why is it that trucks need it and not these locomotives when they leave black smoke

That's true.
Even clean diesels smoke a little bit at startup before the EFI has a chance to calculate and clean up the air/fuel mixture.
Amtrak has DEF on their engines you can see it on all of them if you look near the fuel tank.
lokomotif es44dc
Why am I hearing gun shots?
whats the ringing sound at 0:08 i hear it everyday from locomotives in a train yard
