It's kinda the difference between being a train spotter and enthusiast. I feel that an enthusiast cares a lot more about the technical aspect of a locomotive, whereas a spotter likes to document the particular operations of a particular locomtovie.

Level 11: Understanding why boilers can explode. The boiling point of water is a function of pressure. The more pressure, the higher the boiling point. Take the pressure away (i.e. through a rupture of the crown sheet of the fire box due to overheating the steel) and the boiling point of the heated water in the boiler falls quickly. Since the hot water contains lots of energy the water now becomes steam nearly instantly. Steam takes up 1.600 times more space than water and it now tries to rush through the rupture. But there was a lot of water in the boiler... that now has become a very lot of steam which can't all exit through the rupture and thus start to build up uncontrolled presssure. If the pressure then overcomes the structural strength of parts of the boiler it will blow them apart and away. There are examples of boiler barrels and smoke boxes thrown hundrets of meters/yards from the engine by boiler explosions. But flying metal isn't the only danger of a boiler explosion. If you're happen to stand close and don't get hit by metal you'll still have to deal with very hot steam all around.

No it doesn't. It's because they're big metal pants. Don't you know that steam is just photons that come from the nuclear reactor in the firmament? The earth is flat and water is an illusion. They're lying to you. There's no water in a locomotive because they're giant metal pants. The earth is ruled by an AI named Flat Stanley. Think about it. Have you ever seen a locomotive? Have you ever seen water? When you touch superheated steam you can see your bones so it's x-rays. Wake Up!

In a naval context, letting cold sea water (or even warm sea water) into the engine room of a steam ship is very bad news. Cold water suddenly cooling a pipe of superheated steam in a ship containing a couple hudred horsepower worth of boilers (8 naval boilers in the case of the Iowa Class Battleship produce 212 KHP) shatters the pipe due to thermal expansion.

It was really nice having someone explain that the superheater dries the steam rather than claiming it raises the pressure. The level 10 explanation was pretty good, but there are reasons not to run with the throttle full open relating to wear on the valve gear. If the Johnson bar is set too close to the center the ports on the valve gear are in a partially open position longer resulting in more steam erosion of the ports. The higher the steam pressure to the valve gears the greater the wear as well. On the other end, running with the throttle set too low results in hammering the connecting pipes. The old-timers learned the art of finding where the balance between the two was.

There will be a pressure drop over the valve but that pressure drop depends on the flow (amount of steam going through the valve in a given time) in combination with how far open the valve is. When the piston is stationary or moving slowly you have little to no flow and thus no pressure drop. Moving the valve does not change the torque as long as the piston still gets fully filled in time. (slight nuance, during the filling of the piston you don't have maximum force so the average torque will be different if the filling takes longer or shorter) To keep the same torque you would actually need to open up the Johnson bar when going at higher speeds because the flow, and thus the pressure drop over the valves, is higher. Opening up the Johnson bar will reduce the pressure drop and increase the torque.

Excellent video Hyce! So a possible analogy for 'hooking up' or notching back the johnson bar can be somewhat equated to the throttle in a car today. To get moving you typically have to give the car more gas to overcome the stopped inertia of the vehicle, and as you pick up speed you actually let off of the gas pedal because the initial amount of power needed isn't required so you're either going to take off super quick or spin the tires, you will obviously burn less fuel at part throttle as you would with your foot mashed to the floor pan. You'd also use first gear and not 4th to start out. A steam engine isn't quite that simple as you're not controlling an explosion in a cylinder, but rather a compressed, active gas. I say active because it's not just like compressed air at some pressure, you actually have a thermal component of energy tied into that as well. Without getting into really ugly thermodynamics, just understand that hot compressed steam has way more power than just compressed air. Ok, so what practically is going on? At stopped the engineer needs to have fine control of the volume flow of energy from the boiler to the pistons. Because you're trying to acceleration literally thousands of tons, through a contact patch between all the driving wheels and the rail that's maybe the size of a dime, you have to be very careful how you apply that power. At low speed it is easier to just control the flow and use the whole stroke of the valve gear to have that fine control It does waste steam because you have way more energy there than you need, but it's easier to control. Once you get everything broke loose, and rolling in a more or less steady state (let's assume level track for sake of discussion) you're now at the point in the car where you'd start letting off from the gas pedal. But in a steam engine remember that you're real goal is controlling total energy usage... so while throttle is letting the energy get to the pistons, the johnson bar is what determines how efficiently that energy is getting used... Now that you're moving kinda steady state, you can move from full admission (valve open the entire piston stroke) to less admission (moving the bar more towards center and less piston stroke). This is where the thermodynamics part kicks in, such that instead of just flooding the piston with 200 PSI of ridiculously hot steam, you can maybe fill that piston volume with 75% but let the heat transfer it's energy to the motion to do work. Kinda like also going to 2nd gear. I'll call this out separately because this isn't going to be accurate, but for the sake of discussion, you'll get the point, At full admission you push in 100% cylinder volume at say 600 degrees Fahrenheit. When the piston reaches the end of the stroke, that 100% volume of steam has to get out and up the stack, it might leave the cylinder at 550 degrees... but you have a boatload of volume to get out, so that when steam hits the piston to reverse travel on the other side, it can actually move the piston back. There comes a point in speed, where at full gear the valve ports simply aren't big enough to get the steam out of there fast enough to allow the piston to go the other way with the train load and not trying to force the waste steam out too... So, by cutting the Johnson bar back, you might only put in 75% volume at 600 degrees, but now at the end of the stroke, the steam leaving might only be 400 degrees... and... you have 25% less steam volume to shove out to make the piston go the other way.... The more cutoff you use, the less steam goes in, so that might be 50% volume at 600F but now it leaves at 300F ... and so on. And again, you'd use another higher gear, and another and so on. There comes a balance point where once you match flow rate of energy from the boiler to the energy required to keep the train moving at whatever speed you want. You can loosely also equate this to using a higher gear in a car... you start in first, then second and finally end up in 4th or whatever.. You'd never be able to start in 4th, but you couldn't run 70 MPH in 1st gear either. And that gets back to the efficiency point as well... buy using progressively less cutoff as you go, you consume less steam and therefore less fuel to boil the water to make steam. If you tried to run the steam engine at full speed at full gear, bar all the way forward, 2 things will happen, you'll run out of steam, and you won't even get going that fast because of the back pressure issues you'll have in the cylinders and valve chest... Oh and the fireman will probably try to beat you to death with the coal shovel because no human (or probably even mechanical stoker) would be able to supply enough coal and water to match the consumption rate. And as a final note, if you were to come to an uphill portion, just like in a car, at some point you're going to need more power to overcome the grade... same is true here. You probably can't open the throttle any more, or it may already be open all the way, so instead you'll start slowly moving the bar back forward again adding a little more admission, or like downshifting in a car. It's a balancing act. That's a lot to absorb, but that's probably the most simple mechanical analogy I can come up with to further explain what's going on.

@@Ben31337l Speaking as an enthusiast, It's usually weight limits on the infrastructure like bridges, needed power, and what speeds they are expected to run at. With speed the larger the wheel diameter the faster the effective running speed of the locomotive, but the less efficient the power is at pulling heavy loads. This is especially noticeable on lines with heavy grades. A good example of this is the GWR Hall and Grange classes in Great Britain, where the Grange class had smaller drivers and was used for heavier freight service than the Hall class. The boiler size is often dictated by weight limits, although it can be limited by other factors like cost to run and maintain. Grate size usually increases with the boiler size, simply because of limitations on ability to heat the boiler water effectively. Cylinder size and boiler size are also closely connected, because while the cylinders are responsible for putting out the power of the locomotive, there are limits on it set by the boiler's steam evaporation rate. If a locomotive needs lots of power for extended lengths of running, it will be more prone to running out of steam than one in less strenuous conditions and will have a slightly smaller limit on its cylinder sizes compared to its boiler. All of this put together helps explain why steam locomotive designs varied so widely. I'm not really an expert so this might not be the best explanation, but I hope it helps.

@@andrewreynolds4949 "Grate size usually increases with the boiler size, simply because of limitations on ability to heat the boiler water effectively." This is related to the typical calorific value of the fuel that you expect to burn. The calorific value of the fuel, grate size and boiler size are all interconnected from my standpoint. The entire thing is constrained by the MAM (maximum Authorised mass) for a given vehicle length. But given that, the cylinder size and maximum permitted boiler PSI normally determines the maximum HP that the locomotive is able to generate at any one time, whether it is able to put it down is another point entirely. When it comes to weight limits, you can usually get away with a narrower, longer boiler (Smaller radius boiler) spread the weight out over more axles like the LSWR Adams radial tank did. "Cylinder size and boiler size are also closely connected, because while the cylinders are responsible for putting out the power of the locomotive, there are limits on it set by the boiler's steam evaporation rate." I actually feel like this is a false equivellence really, because at a certain wheel RPM at full cutoff, you are going to reach the boiler's maximum HP at a certain RPM regardless of the size of the cylinder. At which point, the boiler will inevitabily run out of steam and the locomtovie reaches an equibrium until an external factor changes. Depending on how large the ratio of the boiler overall volume & PSI compared to the cylinder and the RPM of the driving wheels given the cutoff is wide open, dictates how soon you will run out of steam. And the above is not guarranteed as situations do change, as pressure decreases so does the overall HP of the locomotive menaing that it uses steam less, hence the equibrium.

Nice presentation. I’ve run a Mikado once but never have I had such a complete breakdown of the workings of a steam locomotive before. Well done!

Consolidations and Mikados, the prettiest of the lot ( with exception to Jupiter ), that would be a dream to drive.

This is great! Well explained. I feel like I understood basically everything. I sure wish I could have this video when I was a kid. This is so cool.

Absolutely FANTASTIC job hyce! This is the first video i have ever seen that goes this deep into the components. It took me i think 4 years to accumulate the knowledge of level 9 (i didn't know the frame, you explained it well) and this has taught me a decent bit. I do hope you do one on the Westinghouse airbreak (btw, watch a documentary on him, he is a underknown figure that helped basically everywhere, but he wasn't well known) as i do find the resivours and Triple valve complex. Also sorry for any horrific spelling, and thanks for the vid

Outstanding. Great video, thanks Redeye

Just found your channel as I’m starting to get into steam locomotives. It’s good to see that there are good channels run by people who actually work on them. Thank you for the content!

Glad you found me, and glad you enjoyed! Cheers!

Even though I knew a good amount of this, this was a interesting video to watch. keep up the great work!

I knew a little about the relationship between the reverser and throttle . I always thought of the reverser as like the gears on a car. I also had a vague idea how the valve gear rods worked but your tutorial has given me a better understanding of how it all works, so thanks for this brilliant video well done.

What an excellent video! I'm keeping this as one of my faves

Thank you so much for this tutorial on how a steam loco works. I've heard and read many of the terms, but didn't have a grasp of how they worked. Great work!

This is really helpful! I volunteer with a Southern 2-8-0 in Illinois and this is very helpful. I’ll definitely come back to this for future reference!

Theses things I did not know! A good, well paced presentation. I especially appreciate that you can admit what you don't know.

Once again, a splendid overview! I'm a fireman and student engineer and these videos will make it easier for me to know how to explain these concepts when cab riders ask questions.

I just want to said, Thank you!, been a 78 very old, always want to know about steam engines been electrician, all my life, I appreciate your enthusiasm, for this locomotives, I'm the son of a steam locomotive, engineer in the early 1900 in Mexico, as I said I'm the ninth of ten kid not much time to learn, come to the US in the late sixty's all way's work work, now retired, and with the internet and thanks to your channel in KZread I kind of have an idea of what my dad did back than. thank you again like you videos and your personality to present them god bless you..🛤🛤

Fantastic video! I learned so much! It's interesting how different locomotive engines are compared to stationary steam engines or steam cars. I'm more familiar with steam cars so learning the amazing engineering used on steam locomotives is fascinating. I have enough steam knowledge to appreciate the way they are doing things and to recognize just how very different the design principles are compared to steam cars.

As a steam fan (but not fanatic) for quite a few years, I think that you have done a great job in only 1 hour. The further up you got, the more times I found you filling in or clarifying details- Thank You. At the end you did a great job of covering my wish list of other steam engine/train functions. I guess that my only part that could have used a little more work was the injector system. It seems strange that a steam supply at boiler pressure could overcome boiler pressure and force water into the boiler. I have read about the injector venturis, but it still seems like magic (and invented so many generations ago! ) I would have thought a steam driven piston pump would have been need-like the air compressor. Keep up the good work!

Good job. More learning needed. Thank you for the good work.

This was the best explanation of the mechanics of a steam loco I have ever seen!!!

I knew some basics about steam locomotives, thanks to your video I know a lot more! You are a good teacher!

Dude. Just so much here I have struggled to understand for 50 years, finally presented in a way that makes complete sense. Awesome.

Great video! Thoroughly enjoyed!

I'm an avid steam locomotive fan with an emphasis on Colorado/New Mexico narrow gauge. I've watched many You Tube videos along with DVDs on these marvelous machines. I think you cover the essentials in way that's easy for a novice to understand. Good work!

Thanks Roger! Check back in on the channel in a few weeks. Going to be getting some good up close and personal footage in person quite soon. :)

I visited the Virginia Museum of Transportation today while in the area and decided I want to learn more about trains. This video is very informative and easy to follow! Thanks for this!

this is all the stuff i didnt know i wanted to know about steam engines :D great video

This is a great video, I've always been a big fan of trains, but didn't understand them at all! This answered a lot of questions that I wouldn't even know where to begin looking for the answers.

Easily the best overall explanation I've seen. Thank you very, very much.

I must tell you that you have cleared up so much for me as to the mechanics of steam loco's; I have been a fan of steam for as long as I can remember. I grew up in Canada and had relatives in both CNR and CPRl. For a while I lived in a logging camp in British Columbia where we were still hauling logs to the mill with among other types a Shay. As a young teen, I had a brief run as the engineer. We didn't go far but in my mind it was many, many miles. I am still to this day blown away with the mechanics of a Shay. I now live in Michigan and see mention of Shay in several areas and am not all that far from where they were build in Lima Ohio. Thank you again for this video.

A Shay? Did it run steam? or diesel? that would be amazing to work along side

Love the 101 videos! Great video

Thank you so much for this. I’ve always understood the principles of steam power but never knew about specific systems. Awesome to get to nerd out.

Enjoyed the video!!! Looking forward to more!

Learn somenthing new every day. I volunteered on a tourist railroad with an operating steam locomotive and I just learned about front end throttles and firebox skates. I would be interested in a video about different types of valve gear and how they work. I still struggle to understand how reversing works but wings and strings animation sure helped me understand. Keep it up!

Just plain outstanding work -- thank you

That whole "off topic" part was great. I know about the old races, but not so much of the behind the scenes stories. Good stuff

Prior to this video I was "level 2". This was a really interesting and well explained way to increase my basic knowledge of how a steam locomotive works. Really enjoyed this and glad I found your channel.

You provided a very concise and complete explanation of a complicated and complex system in a way that can be followed. I doubt I will retain much ,but now I have something to remember, and it helps with your start from dead cold vid.

To us novices just beginning to learn the intricacies of how the steam locomotive works, this is a master class. I will never look at a "train" the same way again. Thank you! Thumbs up. Now, on to watch more. Already subbed.

Very well done overview, I learned a lot. Thanks

OBVIOUSLY not the first time you've given this talk :) Very well done.

I already knew levels 1,2 and 4 with some information of other levels, but overall I learned a lot and it was all very interesting (I didn't know 3 because whenever I tried learning about all of the rods it was all very confusing, but you explained it in a way I understood).

Wow that's a lot of information in a short time. That answers a lot of questions for me. Thanks

Wow! I didn't know Wings & Strings made this animation, so cool to hear they are helping out elsewhere as well. Excellent video, Hyce!

You really helped expand my knowledge, now i'm fairly confident in running one.

can we just appreciate at 4:25 how perfectly he draws the air line over the flue line

Bravo, bravo! New subscriber. Excellent presentation!

When i started studying this, it was verryy difficult, i wasn't able to get easy explanation, There is so much to it that it overwhelmed me. I wish I came upon this video before. It is such a great and simple guide. Your explanation was nice

Randomly came upon your video about cabooses, and it made me remember how cool long, old timey train rides were. I absolutely loved the train chapter in Paper Mario The Thousand Year Door. And now I'm watching these videos so I can make a Pathfinder campaign that revolves around driving a steam locomotive from one side of the country to the other. Trains are neat.

thank you SO MUCH for making this video! its been very helpful because im building a steam locomotive in one of my games, and a few parts i couldnt quite pin point. now im more familiar with a wider range of parts.

@@Hyce777 Oh, im building it in stormworks on steam. im not making a "real" locomotive its a custom build. shes a 4-8-4 Northern type, with green cylinder covers and boiler jacket. i can send you some pictures if you want? ive done some XML file modding for a few parts here and their lol

great job explaining all that "stuff". I have been a steam nut for a long , long time now ....now I know what I didn't know. Fascinating ! Just subscribed !

I am impressed at how much I knew growing up and I am similarly impressed with the amount I inferred using physics. (I knew a lot of the information in the video, with the near complete exception of the attaching methods for the: boiler, smoke box, fire box, and axles but it all makes complete sense now that you have mentioned it.)
