The "model" looks like it's a 7.5" gage, not sure though. You talk about talent and skills this man built a beautiful running steam engine from scratch! Amazing!

Yes definitely an inch and a half scale but it could either be laid out as a 7 "1/2 or a 7 "1/4 7 and 1/2 is what took root on the west coast and back to the Midwest the East Coast has the seven and a quarter

your not wrong as someone that builds these things for a living i would say 7.5 gauge to.

A Mallet is just one type of articulated locomotive; look-up Beyer-Garratt, Failie (Double Failie to be exct), Meyer, and also several others. The 'Yellowstone' was the name the D&MIR gave this model, just as the UP named their 4000 class the 'Big Boy'. There is a Double Failie currently under construction at the Ffestiniog Railway in Wales (UK). The loco is being built in the same shops as the first ones in 1870 something; th, meyuch rebuilt over the years, they are still in service.

You have most of your facts correct. Mallet was the inventor of the articulated locomotive, but his articulates used steam twice. Modern articulates used steam steam in both sets of cylinders once, coming directly from the boiler.

In fact, the last main line steam locomotive stood up on the rails in N. America was #2200 Norfolk & Western Y6-b, which was a compound locomotive, so NOT simple steam in both cylinders. The Y Class had 'booster' valves to admit full pressure steam directly from the boiler, but only when lifting the train from a dead stop. After something like 15 mph, the engineman switched off the booster and the engine reverted to compound operations with the much larger front pair of cylinders receiving expanded/cooled steam exhaust from the rear cylinders. Both the Southern Pacific and the DM&IR called their articulated engines Mallets, but this is strictly incorrect. A Mallet, by definition, was always a compound articulated pair of engines under one boiler.

Beautiful looking model locomotive

Good Heavens that's impressive... It needs to run!!!

It would be really great to see one brought back to life and operating.

That model is so beautiful like wow. He did an amazing job. Every detail is there like wow. It's perfect.

Great video have visited over the years starting when I was a little kid. The 227 uses high pressure steam in both sets of drivers so many call it a simple articulated And would call a mallet one that uses hight pressure steam in the back cylinders then reuse the steam in the front at a lower pressure so the front cylinders would be larger. DM&IR has some mallets that they rebuilt in to simple articulateds. Just some info. But great video thank you for posting it.

Both the real deal and the model are amazing items in their own right-and both manage to convey the size. Thanks for making and sharing!

Not a Mallet, all articulated locomotives are not Mallets. A true Mallet is a compound (front cylinders are low pressure), a true articulated is simple (all cylinders are high pressure) and usually the same size.

Correct about Mallets, but an articulated locomotive is simply any locomotive with a hinged frame. Mallets are articulated: they're articulated and compounded. There's no sense in which a Mallet is not a "true" articulated locomotive: they have the defining characteristic of a hinged frame.

28 Years of building and never ran it once on a railway? And it never will? That's just,........ sad. :-(

This is an impressive model of the "Yellowstone" articulated type steam locomotive, the DM&IR class M3,M4 simple articulated (2-8-8-4) types are some of my personal favorite articulated locomotives that I enjoy observing about their history and performance records.

Technically a Mallett is a Compound Articulated locomotive, so not all articulated locomotives are Malletts. So a big boy is not a real Mallett because it is simple (the steam is only used once) not a compound)

@@IndustrialParrot2816 yes, with the long distance between the cylinders it wasn't that feasible because the steam would condense in the line and be wholly ineffective once it reached the LP cylinders. Atlest on the K1s (only compound Garratt I'm familiar with) the cylinders are facing one another to reduce the distance (rather like a Kitson Myer), this has the problem of reducing the available space for the firebox tho.

Wonderful model train

You know, this does bring around an idea. I'd like to know how the 227 got there and it's story on how it got to the museum in a bit more detail. Just thinking out loud do what you want!

You have a wonderful museum, I hope to go back & visit again!

I grew up in the Hollywood area and in 1970 my family opened the shop that built kits complete equipment movie and television models etc... and I have to say I am most impressed by the quality of what I just saw very nice... seems a shame it never got to go out and pull people nothing like making the little kids laugh at the park

I actually have a picture of the 225 that's in my room. I tell you, what a beauty it is!

actully there was another more complicated design of articulated locomotive designed by Herbert W. Garratt called the Beyer-Garratt which were used on railways in south africa and australia but never in the US of A

Wow, the cab of that engine could qualify as a tiny house 😂

HOW DID IT TAKE 28 YEARS TO BUILD A MODEL OF THAT! 😨😰

So happy to see this get the display that it deserves. Are you using a different camera for the last two videos? Focus is off and has a weird fisheye and wave effect.

Some says that those are to cut icicle hanging in tunnel, some says it is to avoid electric sparks. Would you tell me right answer? Thank You and Best Regards. Mike Sekiguchi

The maintenance to keep a model like this running is huge. A friend now owns the Tom Miller Big Boy. It is most definitely not a daily driver.

What Scale is the 227 model, not mentioned in the video?

A 2800 lb “model” 😳

"Mallet" versus "Yellowstone" is comparing two completely different concepts in a way that just doesn't make sense. A Mallet is an articulated compound steam locomotive; a Yellowstone is a steam locomotive with a 2-8-8-4 wheel arrangement. Any given steam locomotive could be or not be a Mallet, and could be or not be a Yellowstone, completely independently of each other. It's like having a discussion about whether something is an apple or a green fruit. It could be both (a green apple), one but not the other (a red apple or a lime) or neither (an orange).

I forgot that the big boy was a articulated locomotive question for you is articulated locomotive better worse or the same as a regular stem locomotive

If they were mass produced, how much would it cost? I think that there ought to be HO scale live steam.

Noticed a slight problem with this you called the big boy in the alley but the big boys not a melee it's simpler tastes like it all of its cylinders are equal the Yellowstone's front cylinders are bigger than the back bear male uses high-pressure steam through the back cylinders and low pressure to the front cylinders big boy has equals things onto all cylinders

Not all articulated locomotives are Mallets. Mallets have high pressure cylinders in the rear which then exhaust to the front, low pressure cylinders. Locomotives with both high pressure cylinders are not Mallets. Yellowstone are not Mallets, they are simple articulateds.

@@MarkInLA Mallet's invention was specifically a compounded articulated locomotive. The point of the compounding was that it only required low-pressure steam through the flexible joints. Putting high pressure steam through those joints required further innovations.
