BNSF ex-Burlington Northern SD40-2 Load Test 

What I wouldn’t give to hear the sound of those screaming EMD 645’s up close and smell that sweet diesel exhaust!!😍😍

May not be Tier 4 complaint but those SD40-2's are still amazing pullers. Nothing sounds as good as those old EMD 2-strokes

Even a modern train lover would love the sounds of old diesel engines!

Gorgeous EMD 16-645 engine sound! Love that

I like how the DB fans speed up in-step with each run of the throttle. I'm glad you stayed with it long enough to catch the radiator fans kicking in too. Awesome sounds of the prime mover and the howling DB fans! As a point of information, this unit was equipped with Harris Locotrol remote control gear in it's early years, late 70's into the early 80's. You can still see the evidence on the cab roof where the two R/C antenna platforms were located. BN temporarily swapped some of these Locotrol units with Southern Pacific in the late 70's to help cover SP's quickly expanding R/C use districts. There is a great article in Winter 2014 SP Trainline Magazine explaining the use of remote control operations on the SP and their borrowing of these BN units. Also, Athearn just released 3 of these units in HO scale and they did an awesome job. Thanks for posting this video.

I love how american diesel locomotives sound like bass boosted jet engines

In my opinion the SD 40 was the most durable locomotive in the fleet . The Gp 38s and 40s were also tough as nails. Engineer , Milwaukee/ soo . C.p 1990 - 1998 .

I have run many of these in days gone by. I used to love it when we ran through tunnels.

I know where this yard is at, I've seen these tests done many times. They're done mostly at night. An absolute blast to watch from that bridge! You truly get the full effect!

I remember standing up on that bridge over the yard and witnessing a few of these back in the days when I was shooting film! LOUD, yet awesome!

ive always loved those sd40-2s

I love SD40-2s

They were really giving the dynamics a workout!

I BLEW MY SPEAKERS LISTENING TO THIS!

the sd 40-2 is the best sounding locomotive ever.

I wish I could loop this a few times to fall asleep to. So relaxing... :)

Whooo HOOO Listen to that EMD SD 40-2 I love the sound The sound systems in model trains sound almost close to what i'm hearing. Awesome! Yes! This gets a 5 star ⭐⭐⭐⭐⭐👋👋👋👋👋👋✅👍

That's sweet dude!!! Those SD40-2s are like those muscle cars the way how BNSF shows them off to you.

Great Vid!!! Love tha sound nice catch!!! Amazed at how long in run 8 b4 radiator fans finally spun up!

Listened to this the whole 9 mins straight, definitely worth it

This is delicious! It sounds like an epic washing machine!

When God made EMD He made an AWESOME thing.

The pure sound of raw power!

GREAT video! and sound!!

CSX in Selkirk NY has this same setup, bridge right overhead. Id say nearly impossible to know when to be there when they plan a load test, but Ive seen them before a few times. Thumbs up to your video!

Thanks...glad you liked it as much as I did/do! I'm a few hours away too but I have relatives that live a few blocks away...lucky me! lol

Great catch!!!

Very interesting to see the radiator fans behave the way they do. I had always wondered if there was an air baffle separating the fans. Turns out there isn't. You can see, when the front fan starts, the middle fan freewheels, then reverses direction as it starts up, the rear fan behaves the same way, freewheeling in the wrong direction as air is sucked from there to the other fans. It would be more efficient to separate the fans, adding baffles directly to the radiator to make sure air is always pulled through it, and not back thru the open vents above non-running fans. I suppose that's why they start up nearly at the same time. Also interesting to see the dynamic brake fans increase speed with the engine's different throttle positions. I would've only imagined one or two fan speeds for those. I doubt their speed is directly related to the output of the generator. FANTASTIC video! So much to observe, so much to listen to. There is no sound like a turbocharged EMD two-stroke, absolutely none. You are actually hearing the gears for the turbo, and not the turbo itself. It is shaft-driven through a sprag-clutch until around notch 6 depending on actual load.

Love that sound

I love that sound. I had a crazy dream one night about one chasing me through the house with antenna clause in notch 8. Yes I have a great sense of humor.

Love that sound!!!!!!

sweet sounds of EMD

Excellent video

Personally, in my opinion, the SD-60 produces the the best low torque sound in stereo! Awesome RUMBLE, turn up the subs!

Sounds good

The pencil pushers and Book keepers got rid of these fine units.

Nothing sounds as PowerClean & PoweLean as the EMD engine! GM mastered it!

Excellent song sounds i remember when Erie Lackawanna was double track when i was a kid🍻🎵🎶Schaefer beer.

This was the sound of Tehachapi Loop in the mid eighties.Thirteen EMD locos at full throttle.

honestly, these EMDs Scream. That's the way i like them!

Music to my ears.

Oh for sure! There's been a ton of good stuff up there the last few months!

Keep her lit!!!!!

Have you seen the one video on here where one of the dynamic brake fans loses a bearing and turns into a 100 pound frisbee? Blows right out of the brake grid and lands in the weeds after going about 100 over the locomotive!

awesome!!!

The best 9:44 of my life!!!!

BEYOND BADASS !!🇺🇸

What happens between 6:34 - 6:43 and why? It is a drop in RPM, but is it throttling down or is the load increased so the engine can't maintain the RPM? Or something else? At any rate, it is complete eargazm.

Thanks!

This! I am also surprised...

cool the engines .

I tried to make my sister sleep with this. She concidered this as disturbing Noice. I concidering this as the perfect sleeping melody! :D

Its the equivalent of running an engine on a dyno.

That has to be ten megawatts of raw heat blasting out the top of that thing, between the electrical load and the thermal load from the engine itself.

Couldn't agree more

Emd 16-645e3 sound ASMR

God I want to smell that

Bn engines always sounded different

Where's the load box? In India they still use water loads to load test locomotives. They even make computer controlled water loads.

END make the best train SD 40_2 & SD40 T_2 live on SP god bless BNSF & UP

All well and good folks - but get a load of the Irish Rail 071 GMs... ;) Seriously though, that EMD645 doesn't half make a racket!

She chooches pretty good

is there any way you can rip the audio for a full 9 minute track of this adamski3119!? :D to put on a mp3 device.

2 bnsf facing each other at the side.

.....Supercharger heaven!

*Q: So, is it on a "Treadmill" of some type or what???*

whats a load test?

why doesn1t someone explain what is happening.

What is a load test?

FOAMERS I tell ya

rip headphone users

Discount ESU Loksound 5.0 cliche.

Excellent song sounds i remember when Erie Lackawanna was double track when i was a kid🍻🎵🎶Schaefer beer.

Thanks!
