EPIC Steam Locomotive Wheel Slip
HTML-код
- Опубликовано: 8 май 2022
- On May 7th, 2022, Southern Railway 2-8-2 no. 4501 was assigned to the Tennessee Valley Railroad Museum's Missionary Ridge Local. While backing around the wye, the locomotive started to slip due to wet rail conditions from the injector. Slowly but surely, the skilled crew was able to negotiate the wye at Grand Junction.

A steam locomotive is nothing more than a piece of industrial equipment, an oversized pressure cooker. And yet… it’s one of the most beautiful and fascinating things we have ever seen.
A boiler with 250# of steam pressure is not an oversized pressure cooker It's a very large BOMB!
The most beautiful pressure cookers on earth
My pressure cooker has no wheels!
Главное едет на воде и на всем, что горит😁🥰

When you see gorgeous moving pieces of machinery like this, you can't help but feel we have let our standards fall in terms of beauty. What a skill it was to crew and man these and what beautiful technology they still are.
look up "golden spike national historic site locomotives" as those are even more works of art... Back when people cared about how things looked for sure.

Thing is that these trains were very hard to maintain and required tons of labour, which of course wanst good for revenue for train companies. I still love them though, engineering marvels, and to think these were designed using a paper and pencil

That's called rose colored glasses. At some point in the future someone is gonna say the same thing about trains now.
Those wheels were really slipping as the engine started around the wye. The crew did a great job of controlling the wheel slippage to keep the train moving. Thank you for documenting this!
Why was there so much wheel slip? Looks like there were only three cars attached?
I just read the answer in the description.
Especially since nobody let it get out of control and “Blue Petered” 4501.
@@Green4321 Going around a sharp bend I'd say. There's no differential action of the wheels to account for the different radii of the rails so wheel slip could be induced by this.
I couldn't see the wheel sanders working. It's possible this was deliberate since it was being filmed - either that or they were working and I'm wrong.
@@ThePaulv12 At first I didn't think there were sanding pipes for reverse moves, but there is one behind the third driver. Maybe they were out of sand or maybe the sand pipes were blocked with wet sand (it happens...). Could have been on wet, greasy or oily rail, especially if there was a flange lubricator for the curve. Excellent throttle control during this move!!!
I am 77 years old and remember these beautiful Iron beasts while growing up in the 1950s. My beloved late father worked 38 years for Southern Pacific on the Bridge and Carpenter Gang. I have fond memories and pictures of him. One in particular catching Hot rivets. R.I.P. Beloved Dad.
R.I.P. Beloved Dad🙏
R.I.P beloved guardian 😢
The scene in which the #4501 rounds the bend before the tunnel with the whistle blowing is incredible. Feels like this is how it would have been 80 years ago. Thank you and stay safe!
It gave me chills down my spine as a haunting sense came over me, what a great feeling.
Less than 80, I am 74 and remember icy morning wheel slip.
This is truly beautiful.
7:10 it may have been an era when these locomotives got old school that locomotives did not impress but which era was that? I still say this is a living breathing beast that humans must just must stand in awe.
Great talent at the throttle, he didn't even let them slip a full revolution.
ruclips.net/video/F9bH3M-5iYE/видео.html
It's amazing to see this locomotive still operating!! My wife and I chased it from Manassas to Front Royal, Va., back in 1974 when the Southern had its steam program!!! It was in the Crescent Green Southern paint at that time, even though that was never what it wore when in regular service. I like it in both paint versions - it looks really great here!
Fifteen or twenty years ago, I was on a run from Wairoa to Napier. Our excursion organiser had put on one car too many, and the line had a ruling gradient of 2^%. The driver, as in this video, skilfully walked the train up to 3 successive crests on the throttle.
Al it took was frost on the Christchurch rails in early morning and the best loco would slip.
It's worth noting that 4501 is a very "slippery" engine to begin with. As one of the earlier Mikados built, Baldwin was still experimenting with design elements such as driver diameter. 4501 has larger drivers than most 2-8-2s and slips her wheels very easily even in dry conditions.
Huh? Larger drivers than most 2-8-2s? What are you smoking? 63” was a very established driver diameter for Mikados. See WP, UP, SP, NKP, need I go on?
The increase of the boiler pressure from 175 to 200 (and slightly to 205 in 2014) PSI add to the slipperiness of 4501 as well. The factor of adhesion has dropped as a result of this and other modifications made to 4501 by the Southern in the 1920s and 1930s.
Is there a chance that it is spinning easy due to the tight curve of the track, just thought that may not help at these speeds.
@HashDogg06 absolutely. Curves have the same effect as grades, so that isn't helping
@@jacobwoods8738 Just going to add some back of the envelope calculations and an explanation for the factor of adhesion for people that don't know. Factor of adhesion is the weight of the locomotive on the drivers (tractive weight) divided by the tractive effort of the locomotive. In the USA at least, the idealized factor of adhesion is 4. When less than 4, the locomotive is more likely to slip, while being over 4 means the locomotive is likely a bit overweighed for the tractive effort. Most locomotives were designed to be between 3.8 through 4.2.
4501 as built had a factor of adhesion of 4.18 when she was 175 PSI with 51,638 pounds of tractive effort. However, bumping up her boiler pressure to 205 PSI, this increased her tractive effort to 60,490 pounds. If the weight on her drivers remained the same as built, this would mean that the modern 4501 has a factor of adhesion of 3.57. Historically, many locomotive crews complained about locos that had a factor of adhesion 3.7 and below about slipping. Therefore, mathematically, 4501 can be considered a slippery locomotive.
As from what other comments have said, there are other elements, curves, tonnage, grades and weather, however, I will not say it is the driver diameter's fault. She slips because she doesn't have as much weight compared to her current tractive effort.
Driver knows his stuff. Also the throttle design is excellent, allowing fingertip control.
There’s nothing special about the throttle in the 4501. It’s a single-valve dome throttle, just like thousands of other steam locomotives built in that era. However, there is DEFINITELY something special about the engineer. He did a masterful job of controlling the slips, never letting the engine run away and slip violently. My hat’s off to him, whoever he is.
It feels like he's intentionally quarter slipping the engine imo, just to give us a show
@@datguymiller I don’t think so. He is feeling for the last notch of throttle that will give him maximum power without slipping. In this situation (sharp curve, backing, perhaps some lube on the rails), that is tough to do. I’ve been in situations like this when running NKP 765 (ruclips.net/video/ZK5YrXvX0F0/видео.html.) It takes a steady hand on the throttle to keep the train moving without slipping.
4501 was one of the first steam locos I remember seeing as a kid. Glad to see her still strutting her stuff, although nothing can take the place of that Southern green and gold she used to wear so magnificently.
hats off to the engineer, its incredibly hard to keep the engine from just taking off once it slips like that
fantastic job on the engine crew keeping that slipping to a minimum
I love this video. When I was about 8 or 9 we lived about 2 blocks from the DeButts yard in Chattanooga and the sound of steamers slipping their drivers trying to get heavy loads under way was just a common thing, night and day. Those wheel slips trigger pleasant memories for me. Thanks.
Love the sound of the steam whistle in the mountains ghostly
Great picture. The whistle sound when she was approaching the tunnel was perfect. Nice work.
They can talk, when I was a kid I was fascinated by them.
Is almost human the way they talk, you can feel the effort on them.
Wonderful machine!
Beautifully filmed! Well done. You captured the spirit of @4501 chuffing her way home.
The camera quality is so crisp!
Agree! :D
WAIT
WAIT
WAIT
Crafty foxe I whatch all of your videos
Wow, the engineer must have a lot of experience dealing with wheelslip to get her up that wye.
ruclips.net/video/F9bH3M-5iYE/видео.html
Engine 70 at dollywood was slipping a bit Saturday when we rode it for 1st run of the day. Good times it's a 1938 Baldwin narrow gage 2-8-2 from the Yukon and white pass rr Alaska. Now in Tn. They also have a sister Engine #192
I've been on that trained before
I live 3 hours away from those locomotives
I ridden in the cab of that locomotive in 1987.
@@amyreynolds3619 wait they did cab rides
@@RailfanLoy Them and Tweetsie Railroad both at least used to do cab rides. There’s plenty of video of cab rides from both parks from the 4 locomotives between them. I’ve heard tell that Tweetsie still allows ‘em, and that you just gotta ask the crew during more regular operations, and not during certain special events. How true that is has not been validated though, so take that bit of hearsay with a grain of salt.
Though the first and last time I tried asking for a cab ride at Dollywood a few short years ago, the crewman I was talking with said they had stopped doing them, much to my disappointment.
Excellent video especially capturing the whistle so well!
Thank you for sharing ☺️
Drayton, great Video! Looking forward to your live broadcasts to begin again! The 4501 was the bug that bit me when I was a child.
That was awesome being here for the premiere awesome video of 4501 thanks 😊
The sanders seem to be blowing air, but not applying sand. Cantankerous sanders are the nemesis of steam locomotive engineers everywhere.
Awesome video! I'm always in video heaven when I'm viewing RR stuff, especially old steam.
I never get tired of seeing the old USRA in action. Proves how good of a locomotive they created!
I think 4501 was built in 1912. About 5 years before USRA. Might have been a base to start with the 2-8-2 light
4501. My favorite next to 630. Ilive in Chattanooga and i go see these locos all the time.
Greetings from the Ohio Porters.🇺🇸 What a beautiful piece of our railroad history!🤩 That was a tight curve & pushing some good weight! 🧐 That would be wonderful to ride & also catch while in motion!🥰 Great action! 🥰😎✌️
The 4501 has a storied career. She definitely was worked hard and now enjoys the life of pulling passengers.
This is a gorgeous 'mike'. It's a joy to watch steam engines operate as they once did when they dominated the land.
Shes not a "mike" shes a mikado
That was awesome. You could have left the entire tunnel run without an edit! It was that good. Beautiful work!
At Disneyland, they have propane fueled steam engines. We hopped on one to get to the other side of the park, and get out of the rain. It couldn’t get out of the station, due to wet rails and a slight incline. They finally backed down the track to get a running start up that grade.
I really love when a twin cylinder motorcycle engine roars but this is unparalleled! Steam locomotives will always have a special place in my heart :)
Moto Guzzi Le Mans guy here. V11..Nero Corsa. 👍
@@pilot3016 Ooohhh that's a great sounding bike! Looks very cool too! I really love how the Africa twin and Tenere sounds!
@@gokulkrishm51 Thx. The Nero Corsa model came with OHLIN's too! Unfortunately they also have a oil pan, oil pick up at the front. Mine is being punished in storage. Total rebuild is needed along with a known oil pan mod to stop starvation. Sad. But what a bike to ride!
@@pilot3016 Ooh that's sad :'(
I hope you can rebuild it soon enough :)
Too bad India doesn't get every bike. So many great bikes never come to India. I really wanted to experience the Tenere first hand, but guess what, Yamaha has no plan to get it here anytime soon! Also it takes time for the updated international models to be updated here! And big bikes cost a fortune here, hahaha!
@@gokulkrishm51 Best wishes to you.
Very well videoed. Lots of views of the driving wheels, that’s what I like to see. Even when the engine went past, the lens stayed on the wheels.. brilliant thank you.
Great audio! Beautiful shots of the locomotive. Engineer did a great job of managing the slips and just coaxing it back. Would love to have seen the throttle action on the other side of the boiler as the engineer was coaxing it along.
It could be the resolution I was watching at, but it looked as though the sanders were not in use during the backup move. That would have helped control the slippage if it wasn't, though sand would be an extra expense that they could avoid... running steam isn't cheap. That shot down the throat at Whiteside Tunnel is always a classic!
4501 would come through fort Payne when I was a child. I went to school at Williams avenue School in the 1970s and two or three times a year that big locomotive would come through. We would all run to the windows and watch her pass. We could hear her whistle for miles before she got there. I lived on lookout mountain and when that train would come through, you could hear that whistle all out on the mountain. Fond memories of seeing that train come through fort Payne.
Ma grandpa told the story, that when he was a kid him and his friends once put some soft soap onto the railroad tracks at a slight ascent near the village where he lived. Then the boys waited hidden behind trees watching the locomotives struggling climbing up the hill. 😁
Absolutely stellar camera work. Just wonderful wonderful footage.
This is Why, I am Still in Love with the Railways
The guy who is driving this loco is a real artist.
Only one word: EPIC!
I got to see the SP 4449 Daylight wheelslip like that once. She had been on display at the Oregon State Fair in Salem and there was a short string of Oregon Cherries tank cars blocking the track out onto the main line. Originally Union Pacific was supposed to bring a diesel in to switch them out of the way, but something or other happened that it wasn't available. So, Doyle McCormick, the 4449's engineer, got clearance to use the Daylight to move them out of the way; when she coupled on, she wheelslipped a bunch, but eventually got the job done. The 4449 is great when she's used as intended in fast passenger service and does decently well with freight, but a switcher she ain't.
I never knew before that this suddent acceleration in engine frequency is a proof of wheel sleeping. I have heard this sound before a few times. Thanks!!
Awesome Drayton! I really need to get back up there to get the 01 this year
Just beautiful love the steam and the whistle machines that ran on water and coal
The wheels are pealing out on the shiny, smooth, wet steamed, track rail!!!
These guys do very good work!
She's a beauty. Nice catch on the wheel slip
2:00 The most elegant piece of machinery I've ever seen. It's a masterpiece.
Where I grow up in the UK we had a little British J-72 0-6-0 tank engine which delivered coal to a nearby coal merchant. I remember hearing it slipping on frosty mornings as it tried to get up an incline.
What a lovely wood just after the tunnel! Lovely engine and well operated.
I'm not aware of ever really seeing wheelslip in reverse. Great catch, Drayton!
ruclips.net/video/F9bH3M-5iYE/видео.html
Big ups to the Engineer! Masterful control.
This is one of the nicest steam locomotive videos that I have ever seen. The video quality is excellent and the audio is mesmerizing! The composition is spectacular and very professional. Sorry for what seems like hyperbole but I absolutely mean every word I write in this review.
Thank you very much! You should subscribe. If you enjoyed this one, we have many more.
@@DelayInBlockProductions Done!
What a beauty! Looks like a light 2-8-2 Mikado with light duty trailing truck, built to USRA standards.
Actually, I think 4501 is a 1912 product. Could have been starting point for the 2-8-2 light
If only this crew was this skilled to keep Gordon from the Railway Series from having bad wheel slip and control it too
4501 is a beautiful engine!😎
That is super cool seeing the big old SOUTHERN wheel slip
Amazing amount of torque. Simple piston just filling up with compressed steam
ChainsawN&W1218, always cool to see driver wheels slipping, seen some good footage of N&W1218 backing up with its drivers slipping.
Very nice shot of the 4501 struggling around the wye!
The engineer is not struggling. I live up here and see this one often. The guys are masters. The slip let's them blow off a little speed without braking or jerking the momentum. The can couple up and not even shudder your coffee.
It's amazing to see outside and just as amazing in the cars.
You have to look for the doubleheader runs videos in the fall. The bend around Rock Spring is like it is 1946.
There was one freight run they were doing to get movie stock footage.. all the cars waiting at the grade crossing and at the Lafayette station were antiques.
Great sounding whistle.
Luv them old locomotives
Right Place at the right time! Good catch
It didn’t look like they were applying sand to help control that wheel slipping, but great control never less!🚂🚂🚂
They only use sand when absolutely necessary because it wears wheel tires and rails very rapidly. For excursion operators re-tiring locomotive driving wheels is a costly endeavor so they want them to last as long as possible. The tires have to be made to order these days. Back in the olden days the locomotive shops often kept sets of them in stock to enable faster turnaround times.
@@rescue270 Thank you for the clarification. I, too, wondered why no sand was being applied but thought that it was related to wear. Sand definitely works to increase adhesion but abrasives absolutely cause shorter service life.
I don't understand why very few loco's use the sanders these days. Slipping can burn the rails, and, if it gets away, can damage the crank axle & other parts.
Excellent driving skills by engineer. Great video. 😊
No surprise that the slipping would occur on the curve -- the wheels are guaranteed to slip a bit sideways because of the curve, and since dynamic friction is less than static friction, that little bit of slide slip primes them to slip in rotation.
Thank you for the explanation, was wondering if it was a grade change or if the tracks were wet to slip like that never occurred to me that the curvature of the track might be responsible
Great video! Just phenomenal quality and sound.🤟Somewhere I have a video of 4501 struggling around a heavily-greased wye down in the Deep South while pulling something like 21-25 ish heavyweight coaches - which was also pretty epic in the wheelslip department😁 But that video quality would be embarrassing by comparison to what you have captured here, which is truly superb.
Anyway, I cant help but notice here that there are some (exhaust stand?) drains blowing oily condensate *directly on the railhead, directly ahead of the drivers* on both sides, and a (feedwater pump?) blowing exhaust and drippings *directly on the railhead, directly behind the drivers* --- pretty much guaranteeing extra slipperyness in both directions, all the time.😂 It makes me wonder if it's intentional...😏The old gal is notoriously "over-cylindered" to begin with, which only adds to the fun.
Anyway, the fact that such a "big engine" is running on such a "small railroad" is an amazing testament to the never-ending awesomeness of TVRM - both management and crews - which somehow make this glorious spectacle possible... at all. Thanks for sharing that awesomeness!
Awesome 👌 dang that's crazy!
I'm from Eustis Florida and I remember that Orlando northwestern passenger car and a few other goodies that are now apart of TVRM
What a beautiful train! I even like the whistle
great footage here thanks for sharing 👌👏👏
4501 working beautifully.
1:39: Love the way the conductor gently holds his mic!
Somehow I knew this was 4501 just from the thumbnail image.
Absolutely amazing, I love this stuff ,people think I'm crazy
You’re not crazy. Welcome to the channel!
I think the wheels on steam trains are very charming when they turn.
Thats just beautiful
Awesome video of 4501!!!
Love the whistle 👍🏻👍🏻👍🏻👍🏻👍🏻⭐⭐⭐⭐⭐
Ole A#1 was up to his old greasing the rails trick again! 😉
Wow! Your videos are awesome and inspire my channel!
Great Video, thank's a lot.
Wonderful view of locomotive 👍
Great video, luv them steam 🚂
It seems unbelievable to me that you can actually spin those wheels with the immense weight on top of them. Incredible power.
I remember from my youth, as I lay in bed at night, I could hear the UP switchers (0-6-0's at the time, before the diesels) struggling to make up trains in the Cheyenne yards, just four blocks from my home. Their wheel slip was quite distinct, and after a while, one could almost identify who had been called for goat duty that night.
excellent whistle
This engineer really know his stuff.
like all other steam locomotives and just southern railway locomotive number 4501 what she just did was amazing and I hope that her siblings 722 and 630 will see each other some day
Well filmed action and a good engineer on there
THE VIDEO TITLE SHOULD READ-
“EPIC THROTTLE HANDLING!!”
THE WHEEL SLIP BEING WELL CONTROLLED!!
KEEP THEM ROLLING BROTHERS!!
👍👍
Excellent control
Company initials + engine # " - A, Severe wheel slip, Out." The soundtrack to every rainy night with beltpack😭...
Incredible
The engineer did a great job in controlling the wheel slip...
Great short video, capturing romance of steam; whistle is not a horn. Steam invented and used before most of us born. Amazing heavy shop labor that went into building and maintaining these locomotives on a mass scale that supported world war efforts. If every drop of oil is gone in future, they may have to rethink burning renewable fuel like wood again.
Trains get a go bye-bye when they're weel slipping like they're zooming
