Anyone else Just finds themself watching driving wheels on steam locomotives for no other reason than looks Nice must watch no matter what?
Yup
Any old steam engine for me
Poetry in motion
Beautiful... remember me , this horn and the wheels, a soviet loco... possible? Or an DDR loco?
What fascinates me is it’s the opposite of a combination engine.. combustion engines have all the working part hidden inside... steam locos have all the working parts o the out side. Like clock works it’s beautiful.
Same
The U. S. term for this type of wheel is a "blind" driver. Fairly common on 10 coupled locomotives, or six coupled locomotives that operate on very tight curves. Often the blind driver is wider than the other drivers to keep it on top of the rail. This can cause problems with self-guiding frogs.
I've always wondered how so many wheels would negotiate a curve with all of them having flanges. Does it also apply to those boogies with 3 axles? 🤔🤔
@@modelcreationz That's what I meant by "six-coupled", meaning a locomotive with six drivers, or three driving axles, ten-coupled meaning a locomotive with 10 drivers under the Whyte classification system, like a 2-10-2.
@@paulw.woodring7304 oh. Misunderstanding, thanks
Our BR standard 9F 2-10-0 locos are now banned from the national network because of blind drivers.
Thanks for the explanation. Can we fix the false flange after.
On your way I realized that this Loco can not take high speed.
If we use the blind driver in our country we want to face many problems.
I can listen to this all day long.
I have never seen or heard so much play on the main driver rod. The bearing appears to be loose as you can see it shift at the beginning and hear the drive rod clicking from the slop as it pushes and pulls the main drive wheel. 😲
I would say there is not one bearing left anywhere that is still good. Painful to hear/watch 😥
@@carsten.hamburg8771 looks like it’s slinging small bits of metal from somewhere.
@@Denvermorgan2000 Could be pieces of white alloy. Often used on locomotives this size. Very soft material, you can work it with a manual scraper even to get any rough edges off after casting.
I've heard worse.
In 3rd world present day service.
Just going to say the same thing. Clearances are totally shot.
Lovely.. enjoyed every minute of it.. especially the sound.. what a fantastic invention. An invention that transformed the world for ever 👍
Yes , and a Cornishman invented the first steam locomotive in the early 1800 s... Richard Trevithick
Blind driver. It's used since there no lateral motion devices on the locomotive. It's helps prevent binding when going into sharp curves
Excellent, learn something everyday, thanks.
What is "binding", if you don't mind me asking? I cannot find any meaningful search result on the internet.
I don't think it's just looking...it's more about the wonderful mechanics involved to move such weight on two steel lines...brilliant
It looks to me that one of the driving wheels is out of round.
What a nice clickety clackety sound!! I can fall asleep on this!! And the pushrod movement is so mesmerizing!
In a different context, the sound is good enough to be used as a rhythm loop
Baru kali ini ngelihat roda kereta flangeless. Kalau di Indonesia ada loko D 30 yg roda tengahnya flensanya lebih tipis dari roda lainnya. Tapi kalau ini bener2 polos tanpa flensa. Unik banget. 👍😊
I am upset by the excessive side play, approximately 1/4, .25 inches in the center rod... the brass bushings should be replaced. Mechanically speaking, that is totally unacceptable... there shouldn't be more than .0002 play in that when worn in... but I am just a Mechanical machinists. I only look at the machine and what should be maximum allowed...🤷♂️
The clicking tells me that the entire assembly is not aligned. That assembly should not make any noise...
I can't even... 1:34 in and I'm 🤮🤮🤮
Impressive. You can see the "out of round" axles and this machine keeps running smoothly.
Wonderful machines.
I love how old machines are waaaaaay better working than our times.
So coool
I love steam locomotives, but I don't think higher running/maintenance costs, higher emissions, higher crew requirements and more difficult operations for running multiple power units on the same consist, and taking 3 hours for a cold start are 'way better'.
Impressive movie! Cheers, Fabrizio
It's a wonder it doesn't all fall to bits
So calming. ❤️
oh boy this is gorgeous
This drive system has some serious wear issues.
that's surprisingly silent for a steam locomotive
unless it's running downhill or something
At speed it uses less steam
A lot of wobbling hey 🤔
Was thinking the same thing
It's an optical illusion, the white paint around the wheel is not uniform in its circuference causing the wheel to look as if it's wobbling. To get a true sense of the rotational axis look at the axle at the center, the other movements you will then see is the movement of the suspension as the locomotive follows the track, I guarantee that wheel nore any of those wheels are wobbling, if they were it would be short lived.
@@docscottish oh well. I see the breaks moving with the wobbly wheel... So, whatever 👋🏾
@@modelcreationz yep same exactly what I saw.
Eh... Your main rod bearing is looking a bit... loose 😂
She may not go real fast but she works hard to give you what she has.
जिंदगी में पहली बार यह वीडियो देखा thank you
Wooww!!! Amazing video !!
Greetings from indonesia railways
Thanks for sharing :)
Watch in 2x for more fun :)
Nope, 1x more fun
Yes
Wow! Great! What is type of this steam loco?
Great video. ☺ I'm guessing with Flangless wheels this train is easy to derail especially around corners.
Some of the wheels have flanges, look closely at the one closest to the camera.
that particular wheel, the flange-less one, looks like it has a bad bearing or journal - i kind of looks like it might be flexing with the connecting rod-
Hearing the whitstle, and seeing the colour scheme makes me think that its german, correct?
Bulgaria.
@@TC-Railhuh, Greetings from hungary ig!
@@rmsatlantic Bulgarian locomotives were often build in Germany, so the whistle sounding the same isn't really a surprise. Also indeed both Germany and Bulgaria used red paint for the lower parts of their locomotives, but if the camera would've showed the rest of the engine, you'd most likely see a green/lime tinted locomotive, instead of a black one.
@@casperreininga3253 ah, thank you.
such mechanical cacophony is music to my ears
How does it stay on the track with no flanges?
Only the middle pair of wheels has no flanges for allow him to pass sharp curves
No side play.
@@AveoCross her not a him a her
@@kadenrobinson7067 not s her or a her it's an it
In german, where grammatical gender still is a thing, steam locomotives are feminine ;)
But the rod bearing's need to be replaced badly she's all wore out the both sides need to be replaced the rods shouldn't have no play and clanking like that
How it negotiates on curves without flanges
Only the middle axle is flangeless!!!! First listen and think, then post!
How fast did the train manage to go at the fastest moments?
30kmh at points 50-60kph mainline seems to me
Without flangs wheel cannot stay on track. Flangs are clearly visible .
@@sanatansinha4314 not all wheels are flangeless only those in the middle. Use your brain if you have one.
@@sanatansinha4314 It’s the geometry of the wheels coned profiles against the rails that keeps the wheels on the tracks. The flanges are to help with tight curves and hold things together - they’re a precaution, not the main wheel guides.
interesting, this is great video, like
I love this ❤️😍❤️😍
how is this type of whell possible?
Beautiful ❤️❤️❤️❤️❤️
Es hipnotizante! 😵
You said it pal
Cotter pin not installed correctly.
With a flangeless train it WOULD be able to run BUT at soon as it hits a curve it will fly off the tracks
NO ... the blind driver (also thus on the UK) is to stop it binding on curves and derailing! Usually applied with 8 coupled or more. Often the third axle was blind ... as the trailing truck was often part of the rigid wheelbase. Often the trailing truck was able to rotate with angled axleboxes (Bissell truck(??)) ... it was uncoupled so could not bind the connecting rods when moving in an arc.
Most model engines had/have blind centre drivers on 6 or more coupled locos because the model curves were much tighter than scale radius.
How this can work on high speeds
Kinda like my love maker till I run out of steam.
so nice !!!!!
How is it running without flanges bruh 😶
The wheel in middle frame is mis_aligned
we can see that it is out of axis
It appears so, but that's not true. That middle axle is the flangeless axle, and as to keep it on the rails at all times its wider then flanged axles. Therefore it looks misaligned when it really is not.
don't know why i see this full video
動輪のブレーキシューを止めてるボルトがロッドと干渉してますが、大丈夫なのかな…
しかし、思ったよりも飛ばすのですねぇ
That axle appears to be bent
Bellissimo
The austrian class 399 has also a flangeless, moving axle th-cam.com/video/oogOsu4byUc/w-d-xo.html

vypadá to na vůli v uložení
Pěkná mašinka ale všude samá vůle Chce to generálku
Lokomotiva vlastně nedávno měla velkou opravu. Považuje se za provozuschopna, i kdiž vubec ne vypada takhle.
