Silent Santa Fe training film for beginning firemen and engineers.
Probably dates from the 1930's.

I find it quite amazing how powerful the expansion effects of steam actually is, all this happens within a nano second, and to think a steam locomotive pulling a Multitude of carriages weighs in a several hundred tons, and some of them could travel at over 100mph... Simply incredible, and all thanks to the Humble H2o !

Best explanation on YT. Crazy to think this method of generating kinetic movement was discovered 200yrs ago.

@OprichnikStyle 6 жыл бұрын

the reverse stick (reach rod) changes the inclination of the arc. the rod goes up so making the movement the contrary from the start. and that's how you go on reverse ferropedia.es/mediawiki/index.php/Archivo:Walschaerts_motion.gif

The steam locomotive was no where near its full development when dieselization took hold. It could easily have been developed to the point of being as economic as diesels and still cost less to build

exelente. de esas toperas se pusieron acá en Argentina 🇦🇷 en una obra de renovación de una estación terminal. a mí entender se tendría que hacer la prueba con locomotoras, además de que esperaba que absorba más energía y ayude al frenado en caso de una emergencia. saludos. también se instalo de la otra marca RAWIE

Didn't realize the boiler side of the firebox generated such a bigger proportion of total steam than compared to the flues. Also know now how some engineers could get so much more mileage than others. They were working that cutoff all the time for best efficiency. I know some engineers purposely ran with a lower water level to generate more steam, the more aggressive ones being the ones who usually blew the thing up. Have yet to find a video of a full size steam engine blowing up. Would be gruesome. Very good basic video.

Nice explanation, however, I'm still not quite clear on how the exhaust steam gets out of the cylinders and back into the smoke stack to exit the funnel.

@jeredhersh789 6 жыл бұрын

Visionery1 I think the exhaust steam leaves through the front and rear ends of the valve cylinder

@larrygall5831 5 жыл бұрын

Yes. If you look closely, you can see the exhaust steam (outline arrows) is curling up and disappearing through the exhaust port that can't be seen. It's channeled up past the same path it came down through the smoke box and through a nozzle.. making the chuff sound, while helping to push the smoke through as well. By doing that it also sucks air in at the firebox, preventing the smoke from suffocating the engineer, and making sure there's enough air to burn the fuel in the process. I'm no rail expert, but I understood this well. Fascinating to watch this.

the cut-off of the cylinder is controled from the cab? besides the expansion on the cylinder, what other difference does it make into the aceleration? does it behaves like the gears on any other vehicule?

@thomasdupee1440 6 жыл бұрын

Iván Pstyga Not like gears at all. Shortening the valve stroke (aka cut off) by means of adjusting the reverse lever towards the center of the quadrant, results in less volume of steam entering the cylinders. This reduced volume is sufficient to power the piston stroke by steam expansion. This also means that there is less steam volume which needs to be eliminated on the exhaust side, reducing back pressure. The expansion, plus the reduced back pressure, allows acceleration.

@OprichnikStyle 6 жыл бұрын

thanks for the quickly reply. Let me try to get it straight so getting the Lifting Arm nearer the center results in a quickly cut-off thus less steam in the cylinder, a slower acceleration. what confuses me on your comment is the back pressure: Given a low cut-off (slower -I think-) gives in return less back pressure, now, where exactly is the back pressure? and how does it affect. Thanks illuminating me.

@thomasdupee1440 6 жыл бұрын

Iván Pstyga It's difficult to visualize by reading text, but quicker cut off allows faster acceleration, not slower. Longer valve travel is necessary during starting and until the steam chamber and cylinders get hot enough to prevent condensation. As speed increases, cut off is adjusted by moving the reverse lever towards center. Back pressure is always present on the back side of the piston during the exhaust process as the exhaust steam moves toward the stack. The less steam volume that is used to push the piston, the less steam volume has to be exhausted.

@OprichnikStyle 6 жыл бұрын

yeah now I get it visualized i had to connect what you said about the cut-off and another video i saw that he opened a valve to let the condensed water get out of the piston before opening the steam valve. This is most helpful now i get into helping repair the Neilson & C° N°11 a 2-6-0 locomotive

@thomasdupee1440 6 жыл бұрын

Iván Pstyga The valves that are opened to allow the venting of condensation are known as "cylinder cocks" and are separate from the normal exhaust system.

@jimspry7433 6 жыл бұрын

so the reason is diecel is much cheaper but if the fire box was run by air fuel like propane ,It has been proven that if we ran our cars on gas fumes instead of gas liquid we would get maybe 150--------------------200 miles to a gallon , Would the same thery work in a steam engine?

@SBCBears 6 жыл бұрын

Not practical. Propane, for example, contains too little energy for a given volume to power a steam engine. It could drive a steam engine, but you would have to burn so much propane that you would have a problem storing it aboard the train. The same is true for cars and trucks. Propane is okay for short trips and where you can get frequent refills, not for heavy applications or long trips.

My dad worked on the rest ,b&o,back when they still had steam engines in service said he liked them over the new diesels!He said he hated diesels for thier exhaust fumes in those days was so rich with unburned diesel fuel it would give him a stomach aceh ,and the hi pitched noise from the generators would deafen you ! I don't know myself but he quit to work in the coal mines,witch he said wasn't to good either so he started his own mining company.,he ran those untill a stable over releasing mine water he went to court and won his case saying he could put in treatment ponds but then lost his order for coal sales to the Elizabeth coke works then he started a sawmill,this fared no better as his partner embezzeled money from the co. Untill he quit that as well then he worked on construction as a carpenter untill retirement ,but boy he tried good rest his soul ,!I often wonder if us five children may have had it better if he succeeded in his many I'll fated buissness attempts!

When you get no sound so you go mad scientist, turn up and down the volume, plug in and unplug your headphones, open SoundAbout app and change media audio to headphones and back to speaker again, turn the app off then on again, deactivate SmartConnect, and finally smack the phone and jiggle your headphone wire only to read the comment section and find the video has no audio... -.- (My phone's a Xperia Z5 Premium with an audio defect. New audio port and soundboard replacement. Doesn't send audio out the speaker or headphones unless forced to because they never had my password to gain access to the phone and setup the new driver. Have an app that does it for me every time I use it. I truely thought my phone was giving me atitude again... Pretty funny actually.)
