Recently restored steam locomotive BDZ 16.27 (DR BR42 - Kriegslokomotive KDL 3) at its very first test train service. Subscribe to stay tuned for new videos: / @tc-rail
That's all been taken into consideration. The wheels are balanced to make those big masses of steel stable at such high turning speeds. The big red chunks in the wheels are counter-weights that balance the wheels as well as the connecting rods.
I guees it's because no railway curve is as tight as we simplify in our brains. The curves are so wide that, the barely noticable wheel conicness doesn't let flanges get into play most of the time. But if we imagine a railcar and a curve, our minds may have a little difficulty in imagining realistically. Because the railcar and the distance between the rails would be so small when compared to the curve. It would hurt the things looking detailed in our brains.
@@Bassotronics Yeah, I guess. I saw them at their depot. The wheels were screaming on the curves. Trams too. Apparently, trams can even ride on their flanges, sometimes.
@@michaelkolano8686 Mostly no but keeps the bogies in check and are important when curves get really sharp. Especially with Subway trains the flanges are always doing work.
It seems to accelerate quite quickly. It makes some very unusual sounds. Sounds like there is an AC or DC generator, A boiler feed pump, and an air compressor ? Also there is a linkage that moves up and down from time to time, what is it's purpose?(I was thinking some kind of advance mechanism or is it just the brakes?) Awesome video and nice train.
Coolkeys2009 The linkage is part of the valve gear. It has several purposes. It operates similar to a transmission in a auto--forward and reverse and how much steam(water) is used per stroke. When the linkblock in the link is all the way down the locomotive is in forward, the valve travels it's full stroke and almost all of the steam is used to move the piston(turn the wheels). As speed increases not nearly as much steam is needed so the linkblock is raised closer the center of the link making the valve not travel as much and admitting less steam with each stroke thus the engine is using steam expansively saving steam(water and fuel). When stopped the linkblock is put in the center of the link(neutral) and the valve won't move. Reverse is raising the linkblock all the way up or the opposite end of the link. The linkblock is connected to the forward/reverse lever or wheel in the cab and is controlled be the driver. Hope this helps your understanding.
Roy Reynolds Why not just decrease the amount of steam flow from the boiler if you don't want to go any faster instead of this more complex arrangement?
+Coolkeys2009 I think you need to read Roy's comment again, but I think you may be missing something.You're questioning why every single locomotive in existence has this feature. As a locomotive increases in speed, the pistol moves backwards and forwards faster and faster, reducing the amount of time a set amount of steam has to expand. If you have the reverser set to 'full forward' for each stroke, you're letting in steam for 80% of the piston's travel. This will give you maximum power at low speed, like first gear in a car. At high speed, all that steam can't expand enough to give all of its power so it is wasted. So you need to be able to let in less and less steam to go faster and faster, like selecting higher and higher gears as you speed up in your car. Imagine how wasteful it would be if you were driving around at 40 mph in first gear, if you reduced throttle like this, you wouldn't go faster in your car, you would slow down. The same is true in a steam locomotive.
+Samuel Zelter When I originally asked the question I was thinking about Phase advance used in electric motors and Ignition timing advance used in internal combustion engines for the same thing. Thanks for clarifying.
+Coolkeys2009 The engine accelerates quickly because it's a goods engine running light. The linkage you refer to is the radius bar, part of a Walschaerts valve control. It's operated by the reverse-lever in the cab.
2:50 I noticed that upper rod periodically ascends when accelating, and probably descends when slowing down. Edit: It actually did descend as it slowed down when I kept watching. Another edit: I think something in the footplate maneuvers that rod. Correct me if I'm wrong.
Yup, that's the reverser (comparable to gears on a car). The farther down it is, the higher the % of the cylinder stroke steam is admitted, the farther up (until the middle point) the less %
@@the_elden_kingjah I'll use my mediocre knowledge of steam trains here. The link that moves up and down controls, along with a lever that is connected to the connecting rod of the cylinder, the flow of the steam in the cylinder. When the reversing gear or link or whatever is near either of the ends of the swinging bar, the valve moves furter back and forth, putting more steam in the cylinder. When it's near the middle, the valve moves less, and because it's connected to the piston(at the connecting rod) more in sequence with the piston, so not only is there less steam, but it's also being put in earlier. So when accelerating the locomotive with much load, the reversing gear is near the end of the swinging bar, and with gaining speed you slowly crank it up to about 30%, to increase the efficiency. So some small, slower locomotives don't even have that gear. And if you want to go backwards, you crank the lever all the way up.
@@the_elden_kingjah naaah don't worry, it's probably my crappy explanation. It's much easier to understand when you see it, i bet there are good videos here on youtube that explain the idea.
This is so COOL.... I love these videos.... :) I guess every time it stops they are filling the tank with water... am I right??? More videos like these please....
it is common use to put the valve rod in mid gear during stops. if the engineer leaves it in forward gear (down) and by accident the regulator is pushed open the engine will move !! by putting the valve rod/linkage in mid gear this cannot happen.
In the view starting at 12:40 there is a linkage at the left attached to the side rod that spins similarly to the eccentric rod, is that a linkage for the speedometer? Or is that for a lubricator? also, at 14:02, whats the chuffing noise?
Good video bro😁👍 Yups,Old System Technology Sistem pembakaran luar👍🤣 Hanya kereta uap yang mengadaptasinya😁👍 Sorry,i am lil a bit english bro🙏 Thank's you're share video🙏👍
Those bars must weigh like 2/300 pounds easily. Just imaging the forces and weight getting multiplied by speed. Must be like 5/10 tons jinking on those wheels every revolution...
*I never knew how aggressive it looked!*
It's a great site to see with the smoke coming out of the funnel
I love steam trains but something about big masses of steel moving about so quickly makes me uneasy :D
i feel the same about it...i feel like, those big masses of steel (or any other heavy material) shouldn't be able to move this quick
Same. I feel the same about large animals. I give both wide berth. I admire them but also fear them.
That's all been taken into consideration. The wheels are balanced to make those big masses of steel stable at such high turning speeds. The big red chunks in the wheels are counter-weights that balance the wheels as well as the connecting rods.
And heavy iron lol
I can listen and look to this till I fall asleep. Steam loco's, maybe the most fascinating machines ever built, there is something magical on it.
1:10 - Imagine the shunting switch wrongly set...
Hypnotizing... good video. Love steam locomotives. Nice wheel spin @12:58
I do to
Imagine that some steam trains were able to reach speeds up to 200 km/h (124 mph!)
Wow! Love that whistle! :D
It's probably a one chime whistle
This may sound cliche but what always amazes me about life sized trains is how small the flanges are and yet don’t derail on a curve.
I guees it's because no railway curve is as tight as we simplify in our brains. The curves are so wide that, the barely noticable wheel conicness doesn't let flanges get into play most of the time.

@@Santibag
Subway train curves can be super tight though.
@@Bassotronics Yeah, I guess. I saw them at their depot. The wheels were screaming on the curves.

Well the flange isn't really what keeps it on the rails for the most part
@@michaelkolano8686

Its amazing

A Marvel of Engineering !!

But wait a sec it seems like when it goes DOWN when the train isn't moving the train STARTS going then when the rod goes UP it ACCELERATES more.

Very beautyful Video.I love old Steam Locomotive.🚂🚂💝💝💝💝
That reminds me, I'm on a promise tonight!
This is so COOL.... I love these videos.... :)
I guess every time it stops they are filling the tank with water... am I right???
More videos like these please....
I find it interesting how the johnson bar is moved at different time, especially during stops. That one doesn't make sense to me...
kleetus92 it's them changing the reverser and that moves the piston valve (I don't know what the johnsons bar is but I'm guessing)
it is common use to put the valve rod in mid gear during stops.
if the engineer leaves it in forward gear (down) and by accident the regulator is pushed open the engine will move !!
by putting the valve rod/linkage in mid gear this cannot happen.
Moved away from midpoint gives more mechanical advantage at cost of fuel and speed? It's a sort of CVT :D
@@johngroenen ah... that's the answer I'm looking for!
@@620class5 Johnson bar is just the american term for reverser, as most in the US are of the vertical lever style.
How cool ist that?!
Amazing and very,very beautyful Steam Locomotive.💝💝💝💝💝

Yes, it's the speedometer linkage and the noise is from the boiler safety valve.
Страхотен клип! Поздравления !
Браво, невероятен клип за всеки фен на парните машини :)

Holy shit! Amazing how they engineered those heavy pieces of steel to be so balanced to be able to drive smooth without shaking apart ✅👌🏽💪🏽
cool! its still alive =)

Love this video.
Which steam locomotive is the camera attached to? A specific number might be a good clue.
16.27
If the coal replaced with electricity to boil the water in the tank, would steam train be efficient still?
pour some oil!, Too much noise from bearings!
there's some wear there, no doubt.
All steam locomotives make that sound, in fact, the camshaft in a car engine will sound like that, even if it's oiled properly.
Has any one noticed the slop in the reverser link when it starts moving.
Поздравления за клипа! Естествено в твой стил да избереш нестандартно но интересно място за камерата !
Wow! How much does it take to lubricate all of that? Amazing!
Geez.. That's some acceleration!! How much load / how many carriages was it hauling?
I'm a steam locomotives fan my self
Houses running sounds

I wonder if this math is right.
Love Trains, what is the nationality of this train ?
Bulgarian
fascinating...
Awesome!
Awesome
Does steam locomotive have suspension?
멋져요👍🏽👍🏿👍🏾👍🏼👍🏻
They don’t make them like they used to
WHOO WHOO!
nice sound!!!!!!
The puffing and clanging of the connecting rods of the locomotive
Is it force on the down stroke only...
