These models are amazing. Props to the animator(s).
Props to the animator(s) for the props?
yeah they are props to them
I thought the graphics in this were trash!
@povertyspec9651 that's nice
I'm in 7th grade and working on the steam engine timeline and how it worked. This helped me so much and you deserve more credit than is given!
For 9th grade you should build a nuclear reactor.
Did you get a good grade on it?
I didn't start using TH-cam until I was a senior in 2010.. I've never even thought of how convenient it must be for school to have a video essay on every possible subject ever.
@@shotgunsam23 bet
In 7th grade I had Nokia 1112
Great video Teddy!!
Thanks Jared! Glad you liked it.
Hey I know u .Iam one of d subs of ur channel.u do good stuff too
Jared owen make a video of how steam engine works
Um Jared your friend
i like ur videos!
the end of the vid was a little preachy, but rest of the video was Grade A+ content
I found it interesting and well done. Being an engineer, though, I want more detail! There are so many components to a late model locomotive and I want to know about them all!
Over time, more videos will get to more of the components. But ya gotta start somewhere.
he would have given more detail but he had to focus on global warming instead.
There isnt much else to say. Except for the valve gear.
On earlier engine, there are two sets of essentrics, 175-180 degrees apart. One is for forward and the other is for reverse. Later link motion valve gears allowed steam tk be cut off at higher speeds, which allowed smaller amounts of steam to use much more energy and saves more steam from being spent.
Same, there are some interestring details, like latest Czech locomotives have three pistons (th-cam.com/video/gz2xKRIehDc/w-d-xo.html), two chimneys, Trofimov valves that are freely moving on the rod when steam pressure is not applied (idle) reducing moving mass, there some interesting details like superheating steam, water pockets in boiler and last part which i do not understand is kinematics of linkage system (to make it worse, it has to work with dumping and train must be able to turn ... and someone had to design it without computers more than 100 years ago. It surprises me that people were able to design very complicated mechanic machines whereas today we are trying to replace everything by electronics with no moving parts (take drone with complicated and rapidly reacting regulation and simple brushless motors vs helicopter with tilting rotor blades)
@Southeastern777 Oh, go fuck up someone else's planet.
It hurts to see you mix metric units with Imperial units
love the username
2:16 This is not a traction engine. it is a portable engine used for powering machinery using a belt off of the flywheel. it does not have the driving gear to move itself. they have a drawbar hitch on the front that is hitched to a traction engine to move it. And as for the steam being trapped inside the boiler, every steam powered machine has to have a safety mechanism on it. on a boiler is a safety valve witch will open at the maximum safe working pressure releasing excess steam so it does not put the boiler under strain and risk it having an explosion.
I thought I'd search for this comment before I write the same.
What you have shown is a *Portable Engine* , not a traction engine. The main difference is that a portable engine lacks a drivetrain, so it is not self propelled. They were moved by horses to wherever they where needed. Traction engines came later when portable engines were modified or redesigned with steering systems, fuel and water storage, operator's platforms, and most importantly, a drivetrain to the rear wheels.
Lol, I just said the same thing in a different comment. I help operate portable steam engines and traction engines. I have a video of it on my channel. It’s called Fall Steam day 2019. I also have a video of me running a steam roller.
Yeah, at the museum I work at, what you were calling a reaction engine, we call a porta-boiler. They were not self propelled and were usually horse drawn.
It's hard to read your message when you keep saying "where" instead of "were," it's very annoying
@@mesofius there, fixed.
@@harrimanfox8961 you didn't fix all of them, lol.
In your next videos related to engines, please do include how the valves/ports are timed.
Will do!
Excellent explanation of how power moves to a large scale! Way more than that teakettle whistle! Beautiful...Forwarded this to lots of folks!
yesterday I searched for this, finally you uploaded with a concept that is so good. thank you for the new knowledge that you have shared
Thanks!! Glad that you searched for it and found our channel.
The principle on which the steam engine operates is so simple a child of seven or eight years can grasp it readily. The details of making it work reliably, with a tolerable maintenance burden and with slightly better than dismal efficiency filled the careers of mechanical engineers for a century.
Also led to the entire field of Thermodynamics and Statistical Mechanics.
way to go! I really like the illustrations of how to change the molecules' pattern of bouncing around . I also really liked the thought bubbles of what those people, our ancestors, were thinking
Thanks! I'm glad you like them.
This was great content, really well-made. Keep up the good work!
I was directed to your channel from google when I searched how does a screen touch works.
And now I love your channel.
Thank you so much! For the longest time I’ve been trying to make a compressed air engine out of Lego and this video is the reason I was able to do so! It showed me how important a flywheel is and that is the one thing my invention lacked. Again thank you!
This video was great. I finally understand how steam engines work! Thank you
Well explained. Without wanting to sound negative these types of engines were only a few percent efficient. Most of the energy was lost as heat and only a part of the potential energy in the steam was converted into work. Having said that-- These must be the most exciting and inspiring engines ever devised.
You sound negative.
Well i don't see your name patented to any invention.........awkward
@@thecyberexplorer1265 Your point being???? Why would I need any patents in my name to mention the efficiency of steam engines and why would you need to need to suggest this is in some way "awkward"?

Working of Steam engine in pakistan..amazing whistle and sound..must watch
@@jonka1 even centuries later steam engines r still our most powerful source of power we have for mechanical energy purposes. Steam locomotives r around 6 times the power of any of its strongest competitors. And a steam traction engine of over 100yo is as or more powerful than our current best 4 wheel drive diesel tractors of the same size. Using the technology we’ve discovered and invented in the past century we cud modernize the steam engine to a point where we wud be using hardwood chip fuelled steam engines instead of gas, diesel, oil, propane or anything else fuelled engines. It wud simply be able to easily outperform everything else we got even more than it already does. And with how steam engines r wat is used to launch aircrafts off of aircraft carriers at such extreme force and r also used in nuclear power plants.
Beautiful video, well explained and animated. Thank you.
Excellent video for Automobile and Mechanical Engineers
Thanks! I am a MechE myself.
@@BranchEducation that's cool.
We're expecting a video purely on Thermodynamics and it's applications.
I request you to do it in the coming days.
@@shrinidhi6920 I'll do one on heat soon. I don't know if I'll really lay out the 3 laws + 0th, like they do in classrooms, but it will be a good episode.
@@BranchEducation thank you so much. Keep up the good job.
Take your time for quality contents that you create.
Thanks!! Hopefully the next set of videos will come out faster.
Thank you for teaching about these engine design in such a creative way. Now I actually know how Thermodynamics was discovered and used. Wish these concepts were taught in School as well
Learned many new things about steam engines today from this video.
Very instructive. my 5 year old is fascinated by this!
Glad your 5 year old liked the video!
Another video on the same subject left me confused, but this answered everything! Great work!
At last a clip with pressure measurement given in a modern unit - kilopascal. Thank you. Very informative.
This is fascinating. The principles are probably somewhat similar to how our cars operate today, only using combustion instead of steam. Its all very interesting.
Steam is external combustion, the steam is continuous and shuttled through valves to push on either side of the piston. A gas or diesel engine is INTERNAL combustion, the fuel ignites and pushes on only the one side of the piston. The valves are timed to let fuel/air mixture in and exhaust out, so different ways to accomplish the motion of the flywheel
Both steam engines and modern internal combustion engines are heat engines so they are fundamentally similar. The only engines we regularly use that aren't heat engines are electric engines, and that's why they're so dramatically more efficient than all forms of heat engines. This is also why sustainable power sources like wind, solar and hydro are so efficient, they are not heat engines so have an intrinsic advantage when compared to fossil fuels and nuclear power.
How are you so underrated?
Great video
Great explaining
Great visuals
Really well done video... Honestly, great work!
It is really worth time of waiting for a content of such good quality. I watch and enjoy.
Thanks!! It's a slow process, but worth it in the end.
Thank you for every video that you have made. Do not slow down :)
I won't!
I think more than anything those people were thinking: "Holy shit this thing is fucking loud!"
"What did you say?"
"I SAID ITS FUCKING LOUD!!"
Hahah, that's probably pretty accurate.
Wonderful channel!! I love your graphics. About this video, it would be awesome includes Eolípila like an ancient precursor of steam engines.
Great video. Very informative and easy to understand.
this helps a lot with work and you can learn lots from it
Been wondering about that for years. Thanx
this helped me to understand!!! Thx!😁
Great video! Tks for sharing!
Great job, particularly the graphics.
Man your explanations are Top Notch!!
Much Appreciated!
I am hoping ....this channel reach in 1M subscriber quickly
I hope so too.
He should upload such great videos regularly than this channel will reach 1 M
This is what TH-cam should be about! Knowledge to the people!
Beautiful models, thank your for the information
Can we all just stop for a moment and appreciate how utterly cursed the model for that Hudson is?
Very. Cursed.
It got the lone ranger treatment.
looks pretty awesome
What's wrong with it?I'm not a train expert.Can someone explain?
@@Nexalian_Gamer it’s kinda hard to explain without you having prior knowledge, but just look up “New York Central J3a”. It’s the loco this model is based on.
Genius invention from great engineers. Hats off to them and for this u tube channel ( thank u soo much u Tuber. For u r clear explanation about that steam engine.....great)
That was great, thank you for this great video
Thank you for watching! I appreciate the positive responses to these videos.
Should make a video on how they get water into the boiler using injectors and the pressure in the boiler. They are a crazy piece of physics.
4:21 that engine is a hudson, a 1920s - 1940s era design. yet the 19th century headlight and diamond stack make it look NICE!
altho burnng coal did have an effect on the climate, you you look at graphs the problems really rocketed when diesel and petrol started to take over in the 50s and 60s. for cars, rail, and everything really.
coal smoke is mainly visible particles that fall back down to earth
if you get yourself a good fireman he will keep that smoke down to a minimum and your tender as full as possible
Think it was a bit before the 50s and 60's for cars! and the London Smog was made mainly by peoples home fires not transport...ok, maybe the railways added as well then
@@anthonylester1349 50s and 60s is when they were becoming more common place and available to everyone
About 30% of CO2 emissions do come from energy generation and that is mostly in the form of coal powerplants.
this was awesome :D
I needed to design a gear steam train in my College so this helped a lot thanks!

Working of Steam engine in pakistan..amazing whistle and sound..must watch
I remember a documentary on a steam engine that worked in a different principle, but I can't find it. From what I remember it worked by spraying cold water into the cylinder at the end of the expansion cycle and the rapid change in pressure pulled the piston in, instead of a high pressure pushing out. Never mind, I found it: The atmospheric engine was invented by Thomas Newcomen in 1712
I'd love to see how a car and jet engine work!!
This is some incredible work, I wonder if it would be possible to take content like this and turn it into an augmented reality experience. I’d pay for a branch education AR app in a heartbeat~ 🙏🏽🤷🏽♂️
Going to the steam show this weekend to watch live demonstrations mostly on farm equipment. Riding the two stroke motorcycle there so i should be viewed as a "greener" spectator as our cloud of oil comes rolling in to the soot filled fairgrounds.
it was definitely a great technology for its time and very smart to get life of tech started and as we know it today just like all great technology tho we improve over time and move on to bigger and greater things but its always good to know the history that started it all
This video is such a masterpiece. Beautiful work man!💎💎💎
BESTE PERFEKTER VEXPLANATED!
YOU BEST EJEMPLAR!!
MAX THANKS,
This is an awesome explanation of steam engines. So clear and understandable. Thank you! 😊
Timetravelrs - should they just forbid Coal-Use? Can Nature-Damage be completly dodged and if it can, How?
This fire ass animation how does this have 300k views this deserves way more
Amazing invention change the world widely ⚡
Well done!
1:06 Did you just glance over Richard Trevithick? One of the greatest engineers who showed that a steam machine can move on it's own and even built the first steam locomotive.

Video is call how they work, not who made them work
Thanks for this explanation, I also was wondering about this 😃
I need a little more info on the slide valve. Great animation though! Is there a stall case?
Well explained 👏
Great Video!
Dude. Make a video about how the Model T engine works. I was reading about it recently. Super cool machine.
Best TH-cam Video In The Universe, and I Love It a Lot
Thanks for sharing
So much of thankyou for your video's it's all very amazing....and Your Effort fantastic 👏....Again Thank you
Fantastic content.
Amazing video!
Very informative video. The only section that I think could use some tweaking is when you discussed the chugga chugga sound. You did mention it, thank you but a direct correlation showing the valve moving and venting to the stack with a slow motion at first and then increasing. I think most of us get it now, just an aid. Thank you.
Great and very well explained two parter...I learned something today thanks!. Just wondering, could the double acting type be described as a 'One-Stroke' engine? like in the way you get two and four-stroke internal combustion engines.
Intriguing to describe -- even at its minimum it's considered a two stroke engine, four stroke when steam is inputted during up and downstroke
I feel like you should've made note on *how* the slide valve moves in relation to the piston, I can see confusion coming up there.
These Videos probably are the reason for 50% of young Enginners
The most outrageous contraptions in human history. Riding around on giant high pressure kettles.
Brilliant video 🤠
Thanks for share
thank you very much!
Now that's a lot of force
very well made bruv.repped !
Fantastic
The superheater is a pretty neat invention for locomotives(steam locomotives to me are just one great compilation of inventions really, engineered w/ 0 computers, nothing else quite compares), creates even higher pressure steam then what would be used coming straight out of the boiler. And something thats also pretty neat is, trying to picture the steam inside a locomotive being so hot, its entirely invisible until it hits atmosphere. Which is something interesting to compare to the normal "steam" you would think coming from tea pots etc..
A lot of the inventions of the steam engine start to seem a lot less complex when you learn about thermodynamics. Like they're definitely impressive but thermodynamics is just such a powerful tool for examining machines of all kinds that it quickly guides you in the direction of the best designs. Like ideas like the steam turbine follow quite naturally from a thermodynamic examination of the steam piston.
Great video!
Amazing!
Thank you!
The explanation on how a steam engine works is exactly correct, if the piston is moving the slide valve is moving
Well explained tanq sir
It would be so awesome to know how electric energy can be converted to a mechanical one
You could use electricity to heat the water instead of a coal fire maybe
I think as per those days, this was an amazing technology
I love trains so I'm doing a science project for my school project.
wish I could explain as well as you do how my model steam engines work
awesome!
Brilliant video and great animation but the ' traction engine ' is a portible that couldnt move them self. Uther then that brilliant
5:04 is an engine that generates power from high pressure steam against vacuum pressure feasible, instead of atmospheric vs vacuum or steam vs atmospheric?
Yes, but that would be quite complicated and would only net you an additional 14 PSI give or take (one atmospshere). Much easier to just raise the stream pressure int he boiler by that ammount.
Amazing video. to the point and informative. My only issue (not a big one, just pointing it out for future reference) the Hudson 4-6-4. On top of the boiler the steam dome, sand dome, exhaust stack, and headlamp don't seem prototypical for a Hudson. The setup looks like it came from a 4-4-0 american. Especially the exhaust stack. The stack is specifically a wood fired loco stack. And the headlamp reminds me of an old kerosene headlamp. To my knowledge most modern locos had a standard headlight. Like it does on the center of the faceplate. No dynamo. And the cowcatcher looks to again be from an old 19th century locomotive.
Again. Love the video. If I didn't mention what i did, it would of drove me nuts. Please take this as constructive criticism and not deconstructive.
This is Awesome
Excellent video! If you’re ever open to the idea I’d love to collaborate with you on a Tesla turbine video. I have actual working Tesla turbines that output real torque and power even at low rpm. ❤️🙏 agin love your work!
7:55 two cylinders is the minimum, here in the UK we have quite a few four cylinder designs- pretty powerful!
