9000hp WDG4 Struggle to Start on Gradient - Epic EMD Sounds
HTML-код
- Опубликовано: 14 мар 2015
- Twin Kazipet WDG4s, each producing around 4500hp, struggle to move from standstill with a loaded steel train from Jindal Steels. Having stopped on the grade earlier, the loco pilots can be seen trying their best to get the very heavy train moving. The train begins to move only after the locos are put on Notch 5, and once movement is obtained, the train quickly accelerates on the down-gradient ahead. Sound quality could've been better but this is all a DSLR can manage. Enjoy the EMD show!

The epic battle between horsepower, and gravity, great shot - thanks for sharing!
+slamdvw Thank you! :) Glad you liked it!
Its a killer horn and a sinister looking machine. Great humming sounds!
+Pakistan Rail Buff! [Pakistan Railways] Glad you liked it, thanks for the comment!
Absolutely, my favourite..
A salute to the LP! The layman passenger/onlooker hardly notices these overlooked men and women behind the throttle. Imagine the skill required in trying to prevent a mega ton train rolling backward on a gradient as soon as the brakes are released or the precision in maintaining just the right amount of thrust (so as not to break the couplers) to win against counter-thrust. Respect!
You can keep it!
Alp ko nhi karoga
Great observation and words if appreciation 👏👏
However, wonder why the notch up / notch down a few times ?
Also, couldn't the second loco been MU'd aa a banker ?
If there were electric locomotives instead of diesel locomotives, then they could not do it.
Lovely explanation 👌🏼👌🏼❤️🙏🏻
Even at the top notch I didn't see smoke billow out.
No squealing sound means no wheel slip.
Yes simply superb 👌🏼❤️
Them sounds! This is why I love EMDs.
Awesome Mate =D =D ... Superbly recorded =D =D

Same here!! :D
Same to u bro.Love for Diesels especially Alcos but EMD is also not back either
Same bro
Amazing brute power and awesome driving skills..what a sound!!! Imagine the power generated at the wheels and the strain on the couplings !!
That steel-on-steel contact (steel wheels with steel rails) which makes trains so efficient, and allows low power-to-weight ratios to still get heavy trains to high speeds can also prove to be quite an evil when it comes to even mildly steep gradients like this. Where road cars and trucks have better grip due to rubber-and-silicon tyres (there are other chemical compounds as well, but that's a different story) in contact with asphalt roads, allowing them to climb up crazy slopes in lower gears, trains can struggle even on gradual slopes; much more so with such a heavy load to pull. The driver did a great job here, and the melodious engine note is an extra bonus!
Well said
As someone pointed out, awesome driving skills to pull this big load. Salute to the LPs and salute EMD for producing such finely engineered beasts!!
Totally agree
It's humming sound , angry expression , 😍 my fav engine 😍 wdg4
Me to bro
2:47 before they actually started to move! Brilliant video
It will neither harm the locomotive, nor break the couplers. Because, it has been manufactured for that. (WDG: Wide gauge -- Diesel -- Goods). The gear ratio has been designed such that, it can pull ultra heavy loads and could withstand full throttle without burning anything at standstill. I have seen five WDG4s, all on full notch climbing up the hill from standstill..
you are correct,,the EMD engines are made for heavy duty,,,more of them are placed as diesel generators in ships,,and run a lot of hours until the electric transference with the other.
@@nomon95 Yes bro 😍😍
I've worked on emd 567 powered gen sets that have run for 15,000 to 20,000 hours at max throttle, about 900 rpm and are still going strong
5 DG4's together ? Dudhsagar ? It was allotted to UBL for that Only ! 5 DG4's would be required to haul BOXN wagons from Toranagallu to Goa via Hubli, on the Dudhsagar Route. 4 DG4's would be required to haul them from the same place, to Mangalore, via Hassan, on the Sakleshpur-Kukke Ghat Route..
Been looking for a clip like this, watching two diesel locos LITERALLY GET THEIR BACKS BROKEN and FRAMES BENT from being asked to pull way too heavy a load, the engines pushed to the brink of throwing connecting rods and traction motors left smoking and badly burned up! THIS IS TRUE RAILROADING, SEEING HOW CLOSE YOU CAN GET TO UTTERLY BUSTING AND BREAKING THE LOCOMOTIVES WHILE STILL GETTING THE JOB DONE!!
+Patriot1776 Thank you for your comment. :)
Nice Sound!
But the theory of the train not able to move is wrong, the truth being that each EMDs WDG4s can haul 454 metric tons which means that the twin can handle a massive of 908 metric tons at full notch 8 throttle. Truth being the drivers/engineers have to wait for the air tanks to be full as the tanks are emptied after a stop is given which means that the loco has refill the tanks and release the air brakes on all the individual compartments. Thats the reason for the full throttle.
+Zayir Audio Solutions I'm not saying you're wrong, but I was there and I know that the locomotives did struggle a bit to get the train moving. They were notched up before brake release because of the gradient. Trains always do this here and the extra bit of effort is because of the kind of load - this was a fully loaded steel train.
Really bro? Breaking engines is true railroading? Thankfully you have nothing to do with the railways.
These locos can run at notch 8 for hours with out breaking a sweat! The engine is designed for this !
Pretty heavy huffing and puffing by the normally efficient WDG4. Nice to listen to the humming, whistling sounds, then gathering the torque to move along gracefully. Excellent video.
Double powers (4500 Hp + 4500 Hp) are used to haul heavy loads of coal, cement and iron.
9000 hp
The wdg4 is trying really hard full force exerted! Imagine how heavy those carts were when 2 strong locos struggle to pull them
I'm surprised it didn't bust a coupler!
Nice Sound!

+Zayir Okay, thanks
U R right.
You are right Zayir.Don't hear the locomotives strain at all as it goes by.
Zayir
Oh that's great explanation Zayir 👍
and finnally the EMD hero won....awesome video
Thank you!
nice sound...but too much pressure on the coupler..starting a train on 6th notch puts strain on the couplers. SWR should have provided additional locomotive.This affects section clearance.
Nice video and love the looks, power and sounds of these beasts. Seriously no other type of locos has the X factor these EMDs have.
Is it 9000hp?
Ok noted! There is a twin! 👌🏼🙏🏻We love IR ❤️🙏🏻
GT46PAC(WDG4) is designed for heavy loads. So, even after full throttle(notch) at zero velocity, neither prime mover nor traction motors will burn. Their performance may degrade if locomotives are streched frequently to full notch.
Nice video and sound..
Gaurav Kulkarni bro it's GT46MAC NOT PAC
GT46PAC is used for passenger
Thanks bro that relived me.
too cool for the power lines
Even I love sound of their turbos
Amazing with headphones feels like I am there watching live movement. And cracking sound of Wdp loco is like a jet engine.
Awesome treat bro !!!!!
Great show by struggling EMD twins !!!
Really insane and hard struggling EMD'S work power
Dude.. simply superb.. that sound is just awesome
That was one hell of struggle by the twins. For a moment it appeared that the locos would burn their traction motors. Gr8 job by the loco pilots to set it on the move. Superb and rare capture. 👏👏👌👌
Awesome sound of EMD
Amazing shot!
Thank you for sharing this :-)
Wah mere Sher #WDG4 Twins and loco pilots too.🙏
fantastic catched, i loved it too much
Thanks .Fantastic coverage,
Thanks for watching
Very nice video, I love the EMD engine sound!👍👍😅
Man lucky day ,loved the sound.......I felt the power behind the video......EMD lover.....
Nice 3D view amazing experience
I'm a simple guy. I see "Epic EMD Sounds", I clik like.
I wonder what the Stig would have done in this situation ?
2min 40sec to move... uff thts one hell load. Awesome 🐎power loved the horn
awesome! I'm an Alco fan but this was really good!
Very large sound
Emd lover
These emd locos are really giant...
beauty...booming sounds!!
Wow what a sound
Salute to the LP
I like this 👍👍 emd sounds of WDG4
Im curious to know the number of wagons that beast is pulling at full throttle...👌👌
It was the usual 58-60 wagons
Guys use headphones while watching this video
Thanks
Superb
5000 tons of load pulling by twin wdg4
Remarkable video to demonstrate emds Or any diesel-elecric loco power transmission support and adapt according to the country's topography
I think while halting, the wagons were not slacked-in. That would be the reason the monster struggled a bit to pick up..
Most satisfying sound 😘😘😘
Superb Stuff
🙌 thank you
Wow. What heavenly sounds.
A bit risky also being underpowered. Should've have given it a banker at least. Considering SWR has 90% gradients. Pilots would've taken it to 6th notch just to get initial momentum.
Salute locomotive n its pilot..
THAT, ladies and gentlemen, is what MASCULINITY looks and sounds like!
Well said!!!........
just listen to this in full volume 5.1 surround sound...... EPICNESSSSS
+dennis jacob No matter how many speakers you use, this will still be mono sound converted to stereo. :P
That sounds like a jet engine!!
Good capture of EMD notching up...@ 0:36, whether the LP was checking out to see occurence of wheel slip, when nothched up to 2 or 3?
This is one the best videos on EMD locomotives showcasing its power and the sound of these machines is just mesmerizing.
Yes bro DSLR for its sound is awesome..i had taken it at palasdhari UP gradient...
RF Nitin Patil mine's actually not awesome but somehow managed to do the job. It's a mono microphone and is extremely susceptible to distortion at the slightest hint of wind.
Ur vid link plz
the only reason I'll be becoming a loco pilot is this mammoth. Can't wait to feel this aggression from inside of the cab.
too good..
contrary to comforts of passengers, this video will showcase how hard the LPs and ALPs guard strugle for ensuring safe passage of men goods.I salute them. Is there stations with steep gradients?
Our kazipet locos 😘
experienced LP 😍
Super! :O
+vigneshshastry22 Thanks man :D
ALCO's Chugging sound is always better than struggling emd's sound
LOL
Aaaaahhhhh bitccchhhhh i can feel the powerrr!!! 💥💥💥💥
These locos are not struggling. It is actually done so that the train does not roll back at the start of the gradient. Hence LP's notch up before releasing the brakes.
The procedure you mentioned does not take more than a few seconds. The train took the better part of five minutes to even start moving. The train was stopped on an up gradient.
Yes U R right. I just missed the time taken.
Agree with you. If the train had been standing on a rising grade, the service brakes would have been used to hold the train against roll back. Drivers would slowly notch up as the service brakes are released and the brakes slowly start to come off. The expertise of the drivers are demonstrated here in perfect timing: pick up of the load as the brakes come off.
Depending on the length of consist and how the auxiliary / control reservoirs are being charged throughout the consist i.e. single or twin (brake pipe plus main res) pipes, it takes several minutes to release the brakes on a formation. You can never release the service brakes on a train of that length in a few seconds!
Fantastic!
@dheeraj: what's the camera model buddy?
Nalin Dubey Thanks. Canon EOS 550D.
Nice vdo
eargasm
What was the GRADIENT at Biyappanahalli ??
A pusher would have helped. But could it be uncoupled later while underway?
They're called bankers. Yes, they do add bankers only on the hilly terrains. After crossing the stretch, the bankers are removed.
In Indonesia that called Lokomotif Pendorong
I think the wheels of 2nd loco were slipping as it went pass by the camera.
try shooting closer to the loco ... u missed the wheelslip at the start ... dg4 has the best creep control.
It happens
V18 ,super turbocharged i like it
Palash Malik V16
Sounds like a TF39 engine
I was wondering, if the high current delivered during the high notches at standstill would easily damage the windings of the series motors or does wdg 4 use 3 phase AC motor?
James Wilshere All our EMDs use AC traction motors
Dheeraj Rao Anyways, it would overheat at that high a notch at standstill
You are right the Traction motors windings will burn out if peak current rating of the TMs ( in amps) is maintained unduly long. The LP must notch down if the permitted time is exceeded and bring the ammeter back into green zone of continuous rating ampereage value of the motors.
The LP here actually has done a tremendous job of it.
It has taken his complete knowledge of his locos and the proper handling of the notches that finally moved the formation.
I think the station is Bayyappanahalli near Bangalore which has quite a steep gradient and then after reaching the summit a down gradient. We can observe how the LP has cleverly used the down gradient to accelerate his formation.
WOoow Its connected to 3 other engines thats awesome
+Deathstroke Where did you see three other engines?
Hey Dheeraj who has seen the other 3 engines i believe they r invisible & only way to see them is with Mr.India watch so Mr. Vijay ur now Mr.India hip hip hurrah.So plz tell us all how it feels to be one lol.
@@dheerajrao 🤣🤣🤣
Do I see wheel slip ?!
yeah i think i saw too.... the wheels of 2nd loco were slipping
Yes, I though I saw it too...the second loco first wheel on the second set of axles!
Creep Control.
It has creep control..
Emd Beast😈😈😈
Was it brake pressure pulling at the beginning or something else(high rpm before moving?)
They were building up enough tractive effort to get the rake moving without rolling back.
Even one wag9 locomotive would struggle like this
Dem it sound just like jet engine..😍
There was massive wheel spin man when the train slowly started to move...
Aritro Banerjee Massive? Not at all. There was little wheelspin and that too only because of Creep Control.
Dheeraj Rao It looked like that. Since the angle wasn't enough to judge the extent of it, it's just my assumption.
Imagine moving all that with Steam Power!
Fuck!
Not possible with 6big steames!!!
Very much possible in this instance. Easy work.
ALP ke liye apply kardo agar aur nazdeek se dekhnay ye 😂😂
Notch 5??? That's too much, I say!
Very good video are I give you 5 out of 5
wao
Totally how many coaches were there ?
58-60 wagon
@Dheeraj Rao
Can twin wag9h pull the hell of that loaded steel without any struggle...??? i think no loco can match the power of wdg4 and wdp4 monsters........(MY FAV)....as a diesel loco fan.....
Excuse me for being an American rail fan, but it doesn't seem like those engines have the weight and tractive effort that they could for the amount of horsepower that they have. A pair of SD70MACs would've had the same horsepower, but the lash-up would've been something like 250,000 pounds heavier, and had almost 130,000 pounds more tractive effort. They would've hitched onto an equivalent train and walked off with it here in the US. Of course, many railways in the world use lighter rails, power, and rolling stock, simply because they don't have to move as much stuff at once.
so its the tractive effort which matters......not the horsepower.....
Horsepower has more to do with how fast you can make the train go. Tractive effort deals more with how much pulling force you can put to the railhead, and thus how much train you can make go.
Needs to calculate actual load, gradient and most important starting tractive effort.
But starting tractive effort is very high level of force which in turn needs more current (which is of course calculated by on board computer) to motors. Feeding such high current for reasonably long time may damage motor windings so computer won't do it to that extend. Again wheel slip will auto regress the notches.
So the answer to your question lies infact that how much tractive effort is available at axle and how it's distributed under various load conditions.
In my opinion, whether locomotive is electric or diesel, doesn't matter much.
Dear Author,
Video is wonderful. Thanks for sharing. ☺
You need to do some research before even comparing two very different types of locomotives with the father-son logic. A little more maturity would be appreciated.
What a power🖤🖤
The upcoming General Electric and Alstom ELectric Locos can pull these heavy trains with better ease.
Actually these engines are old like 1998 years so it's 2 stroke engine but india is buying ge and Alstom locomotives to cater it's needs for goods trains
meh.
