Usually trains can't restart after stalling without getting more power. Maybe that BNSF stopped for signal 3526 and the crew waited for a better light. But what do I know I just work the UP mountain pool over Tehachapi.

an all day trip there is all you need, it truly is amazing, you can hear the engine from miles away

I love the delicious irony of the very first container wagon with the Swift logo!

This NEVER gets old! I keep playing the video over and over! I would have laved to trainwatch at this location in person! I could watch for hours, And enjoy the sound of the engines at full power working. I grew up in a train town myself! when we were kids, We lived not too far from the katy depot in denison TX. and my grandfather used to work at a railyard in the west part of town. Which was also a tar plant.

The sound in this vid is incredible.

This is my fave go to vid when i want to see ridiculously brutal horsepower at work,the thing fills the whole valley? Amazing,thanks so much for a great clip.

This is one heck of a vid! Great capture! I used to live in Bakersfield for years and my father and I chased Santa Fe and Southern Pacific freight through these mountains! Love the Loop!

I work this mountain and often times the engines will over heat going through the tunnels. They reduce their load and sometimes wont come back up unless we stop and let them cool down.

Ah yeah, they automaticly de-rate themselves until they come back in to exceptable limits don't they? I reckon that may have happened here.

Paul Mauser if you don't mind burning up your diesel engines..

Through experience, I have found out that the GE's will reduce power if they overheat; if either the radiator fluid gets too warm, or the traction motors don't get even air to cool them. They are also known to get "Hot Diodes" and would drop all their power. BTW, darn good video. Hopefully I will visit Tehachapi one of these days. A retired BNSF Engineer.

One of the more interesting Prototype videos I viewed this week

Awsome video, Awsome location, it's on my bucketlist of places to go. Well done.

i know what they did? they put the two pick up trucks on the front and that gave it the extra hp to get up the loop..lol. nice video

A stall and a meet! What a day for you!

I can't believe that whole train doesn't get pulled right off the tracks.

A metallic sound like tinnitus, produced from the pressure between wheelsets and tracks. Unbelieveable the stress in the couplers behind the leading locomotives! We in Bielefeld/Germany decided to use a higher quality of tracksteel in our tube. So we have to change the wheelsets more often. But that was cheaper as the build in of new tracks. And the traffic can go on around the clock!

I would be willing to bet a locomotive fell down for some reason. They probably got it back up and running is the reason they got the train restarted so easy. The only other explanation would be the addition of helpers but none of them were added.

Terry Presnal, I have seen an MU lose control of one loco in the lashup. That loco was spinning it's wheels, adding very little to the pulling power of the string of locos. The crew had to break the train and double the hill, taking about 2 hours for a 5 minute climb. Phil in gorgeous Young Harris, Georgia, USA

The best sounding engine on Tehachapi was the 645E3 you cuold hear them 20 to 25 minutes before the train arrived at the loop

I think he stopped for pizza delivery

super video thank you, what always amazes me is how they never appear to "pinch off" ...thank you again.. Baz

No big surprise here. I was talking to a BNSF engineer in Larkspur, CO and he said that they were notorious for assigning "just enough" power to a train. If one engine goes out (most likely a DC traction locomotive which cannot handle run 9 at such a low speed for extended duration) you're forced to stop and cool the motors.

The setup of the NS dash 9 at 4000hp instead of 4400hp as the BNSF ones is probably what did the train in on the grade.

Yes, I know it's more about tractive effort and AC locomotives provide more of it than DCs. My comment was more about the locomotive consist and the NS unit in particular. I can go on in more details, but I hate typing a lot.

+tarmac2001 a door is open on the 2nd BNSF loco at 14:41, so best guess is issues with that unit.

Fascinant les trains aux U S A.On ne verra pas une choses pareille en France.

like it reason nice view and excellent for field trip.

Awesome video, that is a very long train. I was expecting one or two bankers at the back. Restarting that train must have been an enormous effort for those 4 loco's. Unless they had equipment failure prior to stalling.

Um espetáculo magnífico! A inteligência humana é simplesmente um dom que precisa ser preservada e sempre utilizada para o bem, não é mesmo?

Great video. Sounds like a lot of stress on the track with the heavy cars and locos.

Push boys!

NOW THATS A GREAT VIDEO

To answer some the questions in the comments, NO AC motors don't over heat, and the head end power is anywhere from 16,000HP to 17,200HP, base on if the units are 4,000HP or 4400HP.

A masterpiece.

Should've been a UP train. BTW, it didn't stall, chances are they didn't wanna snap a coupler. They probably would've stalled though.

The Dash-8s are with CN now. The Warbonnets BNSF ordered as well as the ATSF Warbonnets are still being used and I see them often, I doubt any are scrapped. Even the ATSF SD40-2s I see every once in a while, especially around Barstow. As to "up here", I see them nearly every time I go to Tehachapi if you mean Tehachapi as "up here".

35 per day is the average

Super Video!

Any idea what the HPT was on the train that stalled?

Kudos to you, that was just feckin epic!!!

The 2nd is an empty rail train

Ottimo lavoro come sempre,saluti dalla lontana Sicilia.

That was very cool to watch!!!!!!!!!! Thanks for sharing

Locomotives have the most tractive effort when already moving and less when starting. So the less tractive effort means that it wont spin its wheels and stall again. They more than likely waited to see if they could get help or permission to move again.

Realy good video and an awesome place

Hey Trent, did some helpers come and help pull?? I didn't see a clip of them????

Why didn't you continue to film the second train? Did it stall too?

Fascinating; being out of the US I don't know anything about this operation; do they have a depot where additional locomotives can await trains to assist over the summit?

Yep i agree, i a Loco Engineer in New Zealand, i would say Traction Mtr over heat, we get the same here and our old U26C locos with a Brightstar computer system in them does the same when down to a crawl on a hard grade

Not enough power? Hm Gevo-D9-D9-D9 , how much did this weigh? It looks extremely long as it fills the landscape.

What an awesome video!!

With a NS unit. Nice!!!

Now how do you get to a perfect shot of the Tehachapi Loop like that?

Chulada de diseño en las vias fereas

sensacional, magnífico!!!!

True, this train is not long. the sharp curving is what is giving the impression that its long. thats why its climbing slowly and you hear the steal rubbing, It did not stall.

I wonder if that second locomotive overheated since the ground crew seemed to have gotten on it.

If only if a DDA40X or a set of DD35's were used as helpers! LOL

Igot you on the diodes, are they AC, or DC traction, does it make a , diff.? AC traction really wipes out DC, I"ve seen GE ac"S start out on 3 and 1/2 % gradd With 12,000 tons , incredible Machines!!

Maybe the engine was overheat or something? The train had pulled through the harshed part and been climbing down the hill.

I think I can, I think I can, well maybe after a long rest I might...

.....about 390,000 lbs of pull before they break. Knuckles are designed to be the weak link by breaking to prevent string-lining derailments. Sorry for the long response. Just bored in a hotel.

looks like a very busy loop. How many trains come through there per day?

Great video! Thanks for sharing it here. When do you go to the loop? Id love to watch trains there. Thanks!

@lotsoftrains123 I agree the train must had coupled middle and rear locomotives to help pushing. What about if cars could had uncoupled and caused a severe tragedy?

Great catch!

great video!!!

This is a great video....

have you been to the loop before?

OH MY GOD, the greatest of God, the longest train in the world, nice videos , thank

Ok....here is my take, and I have first hand experience with this (BNSF Engineer). When climbing any grade that has the locomotives in Run8 for long periods of time at very slow speeds, the traction motors and diesel engines themselves get to a point where the cooling systems can not keep up. When this happens, the computer will start to de-rate (lower the power/energy output) of the locomotive. Often, there is a point of no return where even the slower speed.....

Ribbon-rail train had priority?

@lotsoftrains123 Right, this train never went above 15 mph ever since it hit caliente

Great video.When do you get up the loop? Id love to watch trains up there.

Stall or Recrew doesn't matter... Great video. Thanks for sharing.

Beautiful loop, how to reach this view point? Where should I park my car ? Lovely video.

Nice shot of track train. That was not a stallec train.

Arent there any HELPER UNITS on this train?

Wow that's one long train......

Thanks

If they wet the tracks it would help the wheels slip reducing the friction on large turns like this making it easier to pull.

Ya ever get any Warbonnets down there? btw nice video thumbs up! :)

What is the purpose for such round a bout trackage. With the resources that BNSF has, they could afford to construct a bypass through this mountainous region

you do know railroads consider a stall once a train gets below 5 mph. It's the engineers choice on weather to set the air then stop of try to keep going.

This train appears to have enough hp/ton ratio to deal w/ the grade. The long train is binding up on the extremely tight curves this hill is know for. Curves create drag& the tighter the curve plus the longer the train, the more drag there will be. Woodford to Marcel is one of the areas w/ the worst curvature & it looks like it caught up to the power & caused them to overheat the traction motors. GE specifies that youhave to stop for 20min to let hem cool if your speed drops at full throttle.

where were you standing to get the view at 5:15. we were just there and i did not get a good shot at all.

Top of the hill next to tunnel 10 right by all the rocks

Maybe the European approach of limiting the max train weight to 2000T isn't such a bad idea. We haul our trains over the Alps with only 2 loco's with 80kmh

Nice video

You obviously have never been to the loop. When I was out there in the late 1990s the SP ran trains twice that long with 9 of more units, 3 or 4 on the point, 3 mid train and 3 on the rear. The Santa Fe typically ran TOFC / COFC unit trains that would fit in Walong with 3 or 4 units on the point.

... what about it?

A new meaning I think I can Now I can't

didnt you see that the train continued without any help after stoping for a moment, if that train had lost traction becouse of the weight of the equipment it was pulling , that train could not continue any more. those locomotives are dc powered and they have to run at sertain speed in notch 8, if not they overheat the conmutators on traction motors becouse amps are to high ,other reazon are turbos, if engine is keept on notch 8 for to long they overheat and engines prootect their selves

thanks

wont the first wagon's coupler just break with such a huge load behind it ?

Yeah, there is a 2.9 MN limit on the couplers. That's one reason why when they use additional locomotives to get the train up the hill they're at the back.

i go all the time but i would say fall is the best time

Sigh... hopefully this can be seen on the Tennessee Pass again if BNSF purchases the line!

Muito bom !!!

awesome sound!! even though its not 5.1 on a 5.2 system (yea .2) its impressive

Did you see how long the train was? The train was a few hundred feet too long, it wouldn't have even fit in Walong.

I would have to disagree. I see Warbonnets quite often when I go to Tehachapi.

They are moving at a RAGING speed of 5 mph! Wow olol.

no, they just couldnt pull any harder and just lost traction. They just waited to get help or let the locomotives reload.
