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!

@@joerivers1768: wimpy Karen. 🙄🙄🙄

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

@@coopercovelo L

That's called rose colored glasses. At some point in the future someone is gonna say the same thing about trains now.

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!!!

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.

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.

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 (kzfaq.info/get/bejne/kLFljNWJ276UdmQ.html.) It takes a steady hand on the throttle to keep the train moving without slipping.

Al it took was frost on the Christchurch rails in early morning and the best loco would slip.

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.

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

Agree! :D

WAIT WAIT WAIT Crafty foxe I whatch all of your videos

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.

@@DelayInBlockProductions Done!

Actually, I think 4501 is a 1912 product. Could have been starting point for the 2-8-2 light

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

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.

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.
