This was probably one of the hardest things to animate, especially the rods and cranks. With more time I would've been able to fully and properly animate them - but, alas. Time was my enemy.
The video explains how steam locomotives use a fuel (usually coal) to start a fire and get water boiling, in order to create steam, which drives the reciprocating piston. Much like a piston in your car, although there there's one tiny "explosion" that happens when the piston is on the top of the stroke (along with a few other pistons).
In reciprocating steam engines, pistons get pushed and pushed, meaning: They get pushed by pressurised steam from both sides, alternating (obviously). Using this back-and-forth motion, using a smart connection to the drive wheel - offsetting it from the center - you can get that wheel to move. And thus, move the train (and whatever it's pulling).
There are different types of steam engine, the most popular one (and the one used in most steam locomotives) is the reciprocating piston engine. A piston moves left and right, pushed by (super)heated steam. This directly drives the wheels.
A few things were skipped in the animation, such as the steam whistle or how the safety valve works. I also left out the superheater, because of time constraints. Basically, what a superheater does, is run the steam entering the main steam pipe and rerouting it passed the firetubes, thus further heating the steam. This to make absolutely sure the water in the steam is too hot to condens in the pistons.
Of course there is more to the story of locomotives and trains than just how they work, the whole idea of moving cargo by train is interesting. As is the rules of the road - or rail, rather - that apply.

There's a new fuel that's just now being used for steam locomotives. It's called torrefied biomass, or "brown coal" which burns hotter and more evenly than coal, and is much, much cleaner. It makes no smoke or soot. They tested this on small steam locomotives at the Milwaukee County Zoo and proved to be successful. A group is now restoring a full sized steam locomotive called Santa Fe 3463. It'll be converted to this new fuel and will run performance tests to see how much more successful steam locomotives could have been. While steam locomotives look slow and clunky, they were very reliable, powerful, and fast machines. What really killed them was maintenace costs. However, because they haven't had a chance to fully develop in their revenue years, it was later believed and proven, that steam locomotives can be just as cheap in labor as diesels.

There are several other problems besides the fuel inefficiency, maintenance, and pollution: - much more work-intensive to operate (although modern automation might reduce that somewhat) - it takes a long time to prepare. Big steam locomotives had to start their fires at least 10 hours before their scheduled start if they were cold. This costs both fuel and labor, and causes inflexibility in the scheduling. - the piston drive leads to significantly more wear and tear on the tracks - you need different locomotives for different tasks, high-speed passenger locomotives have big wheels so they can go fast, but they have less tractive force. To pull heavy cargo, you need smaller wheels and can't go as fast. - even if you have cheap bio-fuel, it might be more efficient to liquefy it and use it in internal combustion engines, as they are more efficient than external combustion engines. - they need a lot of water, which requires its own infrastructure I'm not saying that modern biofuel-burning steam locomotives aren't viable in some niche roles, but steam locomotives have many disadvantages even if you disregard the smoke and soot.

Many of the early "boiler explosions" were actually caused by inattentive firemen allowing the firebox crown sheet to become uncovered and exposing to excessive boiler heat.

What is the crown sheet?

@k4kfh 5 жыл бұрын

@@bobbyhill4715 The firebox is a hollow cavity that kind of "sticks up" into the part of the boiler that actually holds water. If you look in the animation at about 1:19, you can see that the section of the boiler directly above the firebox only has a little water on top of it since it is so much higher than the rest of the boiler. That metal sheet needs the water there to sort of "wick away" the heat, otherwise it will get way too hot and become unable to contain the pressure from within the boiler, resulting in an explosion. The reason an inattentive fireman might cause such an explosion is because the locomotive "consumes" the water in the boiler. The steam that exits the boiler to be used in the cylinders doesn't get put back, it just vents to the atmosphere. So by means of a steam-powered pump or a magical little device called a "water injector", water is pressurized and forced into the boiler to replenish the lost water. Turning the water injector on and off when necessary would have been the fireman's job, so a distracted or incompetent fireman might allow the water level to drop below the top of the crown sheet, resulting in the crown sheet buckling and the boiler bursting.

The boiler/ fire box is running at negative pressure (slight vacuum) therefore the only way gases/ steam could go is through the chimney.

@mandolinic 10 ай бұрын

What the video didn't explain was that venting the used steam into the smoke box and out of the chimney creates a partial vacuum (Venturi effect), which draws more air through the coals, making them burn much hotter. It's called a blastpipe. It was an important development which improved the power and efficiency of locomotives.

The whistle, as u know, is made up of a material like brass, or a conch, like that, such that when air is heavily blown through it, it vibrates vigorously and produces a loud sound. Since the steam is blown out of the boiler with high pressure, the whistle produces loud noise to Scare and Alarm the people to Get Out of the Track, as the Train is Coming

@Shipwright1918 6 жыл бұрын

Nicely done, though if you were ever going to re-do this, it might be worth mentioning that the action of the exhaust steam being shot up the stack creates a draft on the fire by sucking air up through the grates and through the firetubes (the smokebox is sealed so tightly the blast creates a partial vacuum inside it, and the only way that air can come in and fill this vacuum is by coming up through the grates and through the tubes), so the faster/harder the locomotive is working, the harder the fire will burn, and so the boiler can keep up with the demand for steam from the engine. Another important part is the fusible plugs, which are installed in the top of the firebox (called the crown sheet), and are made of an alloy that melts at a lower temperature than the metal of the firebox itself. Under normal operation, so long as water is kept above the crown sheet, it will keep the firebox cool enough to not melt or distort even though the water itself is boiling hot, but if the water falls below the crown sheet, the metal will get so hot it can melt and the pressure will cave in the firebox, causing a boiler explosion. The fusible plugs prevent this by melting and popping out should the above situation happen, causing all the water and steam to go rushing into the firebox to put out the fire, thus preventing said explosion.

when all the water/steam is all used up, do you need to cool everything down to refill the boiler with water? do you put the water down the chimney?

@Shipwright1918 6 жыл бұрын

Diesel Fitter There are devices called injectors that use steam to feed water into the boiler by using the venturi effect through sets of nozzle cones to overcome the pressure. The fireman operates the injectors and adjusts them to maintain a flow rate which will keep the water level up, using a device called a water glass to monitor the level. In practice, while running there's almost always a constant flow of water being forced into to boiler to make up for all the water being used up to make steam. Early locomotives used pumps for the feed water, powered by steam or the motion of the locomotive itself. In later steam locos, feedwater heaters often supplemented injectors. Basically these were turbine and piston pumps that ran the water through coils that were put up in the smokebox around the bottom of the smokestack (aka the petticoat pipe) so the water would be heated by the exhaust steam and flue gases to lessen the cooling effect on the boiler which occurs when injecting non-heated water, which among other things can knock the steam pressure down, which can be an issue when you need a lot of power to keep moving the train, say up a steep hill.

People need to realise what an important machine the steam engine was, and I’m not just referring to the locomotive. The first picture you show is of the Newcomen engine. While not a true steam engine (as it ran on vacuum, not pressure) it started the industrial revolution. There would hardly have been an industrial process that did not use the power of steam. Then the engine branched out into road, rail and marine use. The steam engine in all its forms is the most important machine ever invented. The further development of the engine lead to developments in engineering as well. As the engines got bigger, what are we going to make them out of and how are we going to make them? You could easily argue that just about everything we have and use today, we owe to the invention of the steam engine. The never ending industrial revolution continues today and was all started by Thomas Newcomen and his engine in 1712. One wonders what society would be like today if the engine had not been invented back when it was and the progress of industrial and technological development did not take the path that it did.

and to finish it off, the characteristic "choo" sound is the steam being thrusted through the chimney at regular intervals (due to the mechanics). The reason this is done that way is to create a lower pressure environment in the smoke box in order to pull the smoke along with it through the chimney and prevent it from going back to the cab.

Yeah, it's nice that people give Newcomen credit for planting the seed but without Watt's nurture it would never have grown into a tree. It's sort of like why no one can tell you who invented the first internal combustion engine but people have a vague notion of who Nikolaus Otto is, because Otto so revolutionised it that that it blew everything before it out of the water.

At first I didn’t get it but now it makes sense why the explosions were lethal. People mentioned a crown sheet, which is the top of the firebox. Without the water at the top of the firebox from the result of water levels dropping, an inattentive fireman not regulating water levels, the crown sheet weakens due to heating up more because there’s no water to keep it cool, as a result, the pressure in the boiler releases through the firebox effectively steaming everyone in the cabin alive. At first I was thinking the actual boiler explodes outside and wondered how extreme it would be to kill people inside, still possible, but the pressure releasing into the cabin makes more sense.

I see this a lot on some trains. A train with three driving wheels like the one in this video, the drive wheel that is connected directly to the piston doesn't have flanges (the thin metal parts on the wheel that keep the train on the rails) like the other wheels. Why is that?

Oh that. It's to make it able to take corners tighter. Besides the middle wheel is only used for thrust in a case scenario like this.

A point often not mentioned is that "when the steam exits the valves and passes through the smoke box it creates negative air pressure that draws hot air from the fire box". A steam locomotive engine would be a great deal less efficient without the negative air pressure caused by the steam passing through the smoke box.

That's the science behind a Giesl ejector. It uses tubes to draw air from the firebox to the smokebox and increases the performance (somewhat)

One correction. All wheels connected by the rods are considered the drive wheels. That's really the only error but great explanation!

Most of this I’ve been know LONG before I watched this video (Can you guess how) But this video gave me I few other details that I didn’t know and I liked how explained the steam locomotives were explained
