VIDEO CORRECTIONS (complied from viewer comments): For questions about fuel usage calculations: www.factcheck.org/2008/07/fuel-efficient-freight-trains/ From user @briancelidonia8258: Some corrections (some nit-picky and some significant, mostly nitpicky): 00:00 Front door opens the other way on newer locomotives. This is in case the loco falls on over on the right side (blocking the rear exit door), the front door will flop open, allowing the crew to climb out without having to lift the door. 00:05 The small cranking transfer box shown on the left walkway has been removed for 10 years. (not mentioned in the description) 05:25 The "dummy" recepticle is shown having pins. The dummy doesn't have pins, that's why it is the dummy. 10:27 The Alternator Blower cooling air then cools the rectifier and inverters before exiting the loco. It does not just cool the alternator. 11:24 Only 4 inverter are shown on a 6 motor locomotive. 11:38 "This process may change". Not sure why it would. Inverter control uses "pulse width modulation" (PWM) or "six step" control to generate AC current wave-forms. There really are no other significantly different ways to do it. 12:10 The batteries are under the walkway, not under the aux cab. (way nit-picky on my part) 14:30 The sand boxes are only 1/4 the size that they should be. The nose cab boxes go all the way to the top where the fills are shown. Also, the rear sand fill is not on top of the radiators- maintainers could not reach that high to insert the sand fill hoses. The rear fill is actually about 6 feet above the deck...about eye level. 14:38 Most railroads do not use a 15 mph sand cutoff speed. Some have no cutoff at all. Some have different speeds depending on operating mode. 17:49 The stator exitation does not travel in reverse when the motor are in braking. It travels more slowly than rotor speed, but in the same direction. When in motoring, it travels more quickly than rotor speed...thus "inducing" current into the induction motor. However, I will grant that for general illustrative purposes, it does kind of get the point across (but it does not accurately depict how an induction motor works) 18:18 Grids are show backwards. As shown, the super hot air would burn any person exiting the operator cab on the right side where the rear door is. Blowers should be on the right, hot air exiting on the left. 20:18 "Smart Displays" are no longer used. These are now "dumb displays" called "TCD's" (thin client displays) 24:18 There is no "Smart Display" on the helpers console. Not sure what is shown there but it could be an Auxilliary Speed Indicator (ASI) which displays locomotive speed to the Conductor.

10 year Conductor here. Exceptional video with almost zero errors in information! This is more info than any railroad gives its employees on how this equipment works. Nice video!

The time and effort that goes into the creation of these videos is very much recognized and appreciated. Keep up the great work!

When I retired as a locomotive machinist in 2018 this video represents state of the art at that time. Things like the second turbo are the result of ever stricter emissions requirements. This is video is an exceptional explanation of a diesel locomotive. Well done.

I have worked for many years on locomotives, and this is absolutely amazing. The Alerter system is called the "Vigilance System" in other parts of the world, I noticed that you put an extra effort to use both American and European descriptions for the components. Just throwing in my 2 cents, your video is already excellent.

Keep 'em coming - love these animations!

"Babe wake up animagraffs uploaded"

As a German train driver I'm impressed by the details. Very good job!!!

Not gonna lie. I’ve watched this particular video many many many times over and over again. It’s something about these animations that keep me intrigued. Your narration in these videos is absolutely outstanding. The way you seamlessly articulate the content is such a smooth and pleasant way whilst discussing an incredibly complex machine leaves me in awe. Had I been narrating this, all you’d be hearing is the phrase, “ummm”.

Well Done Jake! I'm retired now but worked for a railroad training department for 28 years as an instructor and manager that developed videos and CBT. Your delivery is exceptional! Kudos To You!

My father was a diesel locomotive mechanic. It still amazes me how these machines can pull the amount of freight that they can from a dead stop.

Better than any training video I've ever seen, and I work for UP as a loco mechanic! Great job. Detail, content, & narration are A+.

I used to work on locomotive engines. This video is crazy accurate and well animated! :)

This is actually insane, I can't believe a video this good is free to watch. Absolutely incredible!!

Jake makes the videos we didn’t know we needed. Instant like, sir. 👍🏾👍🏾

Railroader here, 22 yrs Switchman/Conductor and 21 yrs as locomotive engineer. This was really nicely done!

Just found your channel. These animations are unbelievably amazing and useful. I'm an electrician and your video breakdown of a solar panel was more comprehensive and helpful than any of the literature that I have come across. I am sure these videos are very labor intensive. Please, please keep doing them! You are adding a level of knowledge and understanding to the world that didn't exist before. Also, on a personal note. If you could make some on electrical theory and modern circuitry. Myself and many other electricians that I know would happily pay for these videos. It can be so hard to visualize these principals and you have created a perfect way to do so. Thank you.

Watching videos like this reminds me of how ingenious humans can be, and to not take inventions like this for granted. It’s a humbling experience to see all the engineering and optimizations that go into designing a complex system like this. And there are so many disciplines involved: chemistry, electrical engineering, thermodynamics, material science, etc. It’s so impressive!

Ah yes, the most efficient land transportation method ever invented. Such beautiful machines, and such a great video (the corrections on the pinned comment made it even better)!

This is amazing. My dad was a train driver on this kind of locomotive for many years. As a kid I was fascinated by it and often he would bring all sort of technical drawings of the engines etc to study because he needed to know at least the basics. Thanks for the upload.

This is my favorite Animagraffs episode because I love trains when I was little!

As a conductor in training, I learn better by seeing how and why things work, this helped me a lot. Thanksss

We really don't give engineers enough credit. This is a masterpiece!

Love how animated the Union Pacific GEVO is! I’ve seen a couple of these whenever I was railfanning.

You can't know how many years I've been curious about all things locomotive. However much time toil and treasure went into this, it was very well worth it. Fantastic piece of work.

I am a model railroader. Your easy to follow explainations help me learn more about real world locomotives, just like the ones that opperate on my layout. Thank you.

My grandfather was an engineer for Boston & Maine RR. Unfortunately he died before I ever had an opportunity to tour one of the massive movers!!! I certainly appreciate these marvelous and exceptional videos!!!

Would love to know how long it takes to research and produce these amazing videos. They are amazing, Sir.

They say you know when someone truly understands what they're talking about because they can put it into simple terms. This guy's a genius! Very well done!!

I have always loved engineering cutaway drawings, and feel that this animation is their natural evolution! Thank you for this fascinating and meticulously detailed animation! This was very informative and the high degree of precise information enabled viewers to better understand and appreciate the outstanding design and engineering that goes on beneath the metalwork of these heavy haulers. It will surprise many that there's so much sophistication in what at first sight appears to be a brute force hauler!

Thank you for this. I have been a lifelong train enthusiast. I'm old enough that my grandfather took me to see an old steam locomotive on her final journey. Thanks for the details on how the couplers work!

diesels have gotten really efficient and really powerful in recent decades. they're very impressive machines.

I have no interest in trains, I don't know anything about them, and yet here I was, I was entertained and informed for almost a half hour about them! Every video you put out is of the highest quality, thank you for making them!

This was absolutely amazing. I didn't think I would have sat through 25 minutes. It flew by. Great work my friend!

Jake O'Neal creator of animagraffs, a big congratulations on your work. The models are amazing and the videos mesmerising. Thank you for your efforts!

I’ve been fortunate to be a part of this industry for over 35 years. This instructional video, while there may be a few items that may be different on certain engines, etc., without knit-picking, this, by far, is the very best that I’ve seen. Its quality, details, narration, accuracy, is truly amazing. Great job, Animagraffs!

Respect to the engineers who designed and executed this incredible machine! Respect to the train drivers who daily operate this incredible machine! Finally, respect to Animagraffs for documenting, realizing and sharing this interesting information with us! Thank you!

Another masterpiece from Animagraffs. Thank you so much for creating these extremely well-made animations!

Respect the designing mechanical engineers and all the rail folks operating and maintaining these amazing machines. Amazing!

Animation is unbelievable! Thank you for clear explanation how a diesel-electric locomotive works.

One correction: 2:00 The ant-climber is to prevent locos from climbing on on top of the other in case of an accident, it instead deflects the oncoming train to the side. Otherwise excellent video as always.

This was so much more thorough and covered more than I expected, learned a lot and the inside tour was an added bonus, kinda reminded me of those picture books from school with the cutaway technical drawing but with narration

Amazing. I had no idea trains were so complex and fuel-efficient. Congratulations to the graphics guys and also to the excellent quality of the description. Super-clear. Thankyou

Hey man, your videos are absolutely amazing. 10/10. You deserve awards and you deserve to these videos pay for all your financial needs.

In the control cab, there are even reflections on the engine start panel. Incredible. Best video of it's kind on the web, period. Expertly narrated. Quality 11/10

Praise be! I'm so glad I stumbled upon your channel. The amount of time and effort you put into the simulations has my eyes glued to my phone. Thank you

I absolutely LOVE this video! What a tremendous body of work this is!

I work at at a plant where we actually build these machines in Erie, Pa. I do electrical testing on the Aux cabs, control consoles, dynamic brakes, and other systems that you highlighted here. Absolutely excellent work on the animations in this video. I wish it could be shown here for the edification of all our employees, and I will share it with the other test technicians.

Always had a general idea of how these things worked, but this is more detail than I ever thought I needed to know, and I loved every minute! It's so wild the number of energy conversions required. Diesel fuel to mechanical energy to AC power to DC power, to AC power again, and back to mechanical! Plus all the braking and cooling!

I love these videos, from the components breakdown to basic function descriptions, it's all top quality, thank you for putting this together!

Your work is truly a masterpiece. I learned so much about these incredible machines! Can't imagine the hours it took to assemble all this- thank you! More please!

Amazing work. I cannot believe how you made everything so easy to learn. Now when I look at trains I no longer see just a big engine but all the hard work and dedication that was put into it

My father was the Manager of Hayne Car Shop (Spartanburg, SC) for the Southern Railroad (later merged with the Norfolk & Western to form the Norfolk Southern) from 1963 until 1987, and he would've loved this presentation. Beautiful work, thanks for sharing!

Absolutely amazing!

My first time on this channel. I am beyond impressed with the structure of the presented material as well as the animation. I am looking forward to viewing more videos here. Thank you for the time you spent in producing this video.

This content is exemplary! One of the best break down vids I've seen. Loved every second and have watched it in sections to rewind and go back over information I've found super interesting or to ensure I've gotten every last detail. It's like you've tickled my need for a deep dive into a subject that has always interested me but one which I've never gone too deeply into. I have subscribed...well done!

Very well done! I am not much of a train geek, but I love knowing how stuff works and this hit the spot!!

Wow! Things have really changed since I was a hostler in the late 1960s! Absolutely amazing, and impressive production and narration! Thank you very much sir!!

Marvelous presentation. Simple enough to follow, detailed enough to give a real handle on the workings. SUPERB

May I say that it is epic you have brought to life the books I read for fun as a kid. And you have done so, beautifully! I am going to have to show this channel to my nephew, I think he would love this just as much as I do. I do hope your channel continues to expand!

I have been a Train Buff my whole life and this overview was fascinating... well done indeed!

MY GOODNESS... These models and animations are amazing. The research is equally amazing. Wonderful work!

Freight locomotives are really a great feat of engineering! The 3D visuals are pretty great. One thing, I don't think you went over the stuff on the cab roof, the PTC antenna array

This is an astonishingly good model and it's used amazingly to explain all the intricacies of this system. Well done!

Great graphics. Almost completely correct information on the locomotive's operation. Just a couple very small things. I've been a locomotive engineer for 18 years and I enjoyed the video. Good work.

I learn so much from Animagraffs…thanks for the breakdowns on each topic!

Wow! This diesel electric locomotive animation and explanation is excellent. Way better than crude drawings, schematics and photos. Now I really know what I'm looking at. Thank you!

This by far the best animation of a diesel-electric locomotive that I've seen! Have you ever considered producing an animation of a modern steam locomotive?

It was really interesting to learn about the engines on a railroad . I knew it had a lot of functions and this made it perfectly clear . Thank You !

Outstanding graphics and great clarity in the narrative! 🙏🏽

You are deserving of each and every click! Your willingness to show even the nit-picky corrections is a humility I wish all channel creators deployed. You truly make learning fun! Shalom.

Great animation 🔥🔥🔥. Can not imagine how much effort you put to make these videos.

great solid models. thanks for the time and effort.

These videos are masterful and among the most interesting and educational on UKposts. Thanks and keep them coming.

Very interesting and very well made animations. Brilliant work, Jake and Wesley. 👍 Merry Christmas from Norway 🎄

Amazing detail, incredible graphics. Well done, thank you. This is the best CGI engineering illustration I have seen. The modelling is very impressive

This is probably one of the best 3-D modeling videos I have ever seen. Great job.

This was such a great video! It was super concise, but yet detailed and comprehensive! Now if only companies could hire someone like you to create their safety training...

Mate, thank you very much for making these amazing videos! It is absolutely fantastic. I do admire your high-quality work.

It's funny that I stumbled across this video, because how these things work is something I've wondered my entire life. Thank you for the fantastically informative and enjoyable video to watch!

What a great, informative video! It explained and showed me what I've always wondered about these locomotives. I like trains and have been fascinated by them. Will watch more on these.

What a fantastic video! Full of detail but presented in a way that is easy to follow.

This is exactly what I was hoping for! I knew some of these things, but you still taught me an incredible amount of fascinating things today!

Wowwww this is one of the Internets most informative videos. So well explained and illustrated. The time you’ve taken is priceless. Well done mate. Keep up the good work. ❤

Yes. Thanks for the explanation.

What an engineering. Thank you creator, really awesome animagraff

I often wondered how dynamic brakes worked. Awesome job as usual!

Great animations, accurate explanations, thanks a lot for your efforts!

Yet another fantastic video, great work. Much more informative than classroom studies.

Incredible graphics. Being an Ĺocomotive Engineer it is 99% accurate. Cannot imagine how long it took to make Great Job!!!!

As a railfan this is an awesome video! Well done! For your electric locomotive video - regenerative braking feeds power back into the contact wire for use by other trains. :)

I am incredibly amazed how detailed your explanation are!!! Love your videos... Keep em coming.. Looking forward for more videos!

Understandable narration, non-interfering music, clear graphics… What's not to love?

Incredible, as always. Cheers!

Thanks! Best Animator ever, keep it up man

Never seen such a detailed video on any matter. It takes lot of efforts to create such videography. Kudos 👏🏻

A great animation and narrative explaining the detail and complexity of a locomotive. The quality of the graphics is stunning. Although I've been a rail fan and model railroader for quite a while, this video has me in awe! (I guess that makes it awesome 😁.)

Excellent video, professionally animated and narrated. Well done and thanks for posting! BTW this is the BEST video a train geek like me has ever seen!!!

Absolutely brilliant, your work and dedication to detail is just brilliant. I could watch this for hours my friend, your narration is as enticing as the graphic side of the presentation, what you have produced here is outstanding. Many many thanks and kind regards. tones1957 (from New Zealand)
