Back in the 1800 there was a fixed boiler in the round house that surplied steam that was true for most industries. In the 1930 those was mostly swiched put for compressors. If they wanted to move a loco just a few meters or so they simply presurized the boiler with shop air/steam. If the boiler is att full pressure they can run quite a bit with no fire. Also smaler yards have locos with only tanks that was only presurized by shop air/steam.
Imagine double-heading a mining train with air driven locos like this. Yes, I can see the generator. I'm taking about the really low head space taken. This is so satisfying to watch. I look forward to the steam up
It is not any of them. It has 12 wheels on connected to the pistons. Big boy had 2 sets of pistons, having 8 wheels for each set. Similar for challenger, but 6 wheels on each set
Just seen this masterpiece in model engineering and have gone to bed satisfied that in this troubled world there are still real and dedicated people around. It is amazing to me that seeing this superb machine with possibly thousands of hours of dedicated work built in that there are still those who nit pick, why didn’t they do this or that without a word of praise for those building this beautiful tribute to the real one. I salute you all.
@Tim Spiers Absolutely! Anything worth doing is worth doing right! I will however admit the 3-cylinder locomotives were an absolute pain to maintain, so for live steam this is ok, "BUT", it would have been great to put the third-cylinder in place as a dummy as most would not really see it not working anyway.
I don't see how the middle cylinder would be impossible to maintain. The 9000s had Gresley Gear so all the levers would be on the front and therefore accessible. If roller bearings were used wear would be kept to a minimum and slop should not develop. Between the frames there would only be the drive and the crank axle. After all it is 15" gauge. There are many 5" and 7.25" gauge 4 cylinder GWR Kings and LMS Coronations in the UK. I see that they have decided not to go for superheating.
Its come along ways. I didn't realize you were also building other items since you went to Merrick light railway. I haven't been involved in anything since 2017. The machine work, welding and fabrication is fun but only if it pays well.
Surprised it gets round tight corners with the middle two wheels flanged, here in the UK the class 9f's had to have their middle wheelset flangeless because the middle wheels ripped out points frogs and check rails on the slightest of curves.
@@garthhentley8870 he's talking about switches on a rail line. A check rail is the rail that keeps the axel wheel on a train from jumping the track at a switch or when a train is crossing a bridge in case of derailment. A swingnose crossing or moveable point frog is a device used at a railway turnout to eliminate the gap at the common crossing (a.k.a. frog) which can cause damage and noise. With all those wheels each having a flange it makes it impossible to turn on sharp turns or switching tracks without some way of having each turn individually or having the inner wheels flangeless
The air capacity of a boiler would probably store enough air to keep it going for hours. It could be filled up at a dummy water tank that hid an electric compressor. Getting rid of all hazardous liquids except lubricating oils.
Do you see the big and small cylinders up the front? The purpose was to use the steam twice as it cooled. You would not get this from compressed air. Steam locomotives were developed over 60 years and compressed air would have been used if it was more efficient. Perhaps the compressed air could run at a higher pressure if nothing broke.
@@johnathanhodskins5820 the 9000s had a 3rd cylinder inside the frame, making maintenance difficult for the center cylider and rods, plus the gresley valve gear. The big boys and all other articulated Locomotives did not have this problem, as all the cyliders and running gear was on the outside, therefore easy to maintain.
I had this idea back about 18 years ago when I was 12 years old, at the time as a kid I didn't have the money to make everything work but I knew there was a way
As a kid I used to dream about magnetically levitating locomotives, even drew some blueprints hehe. Now we have the maglev, can you imagine my face when I first heard about and saw the maglev?
How did they keep the pistons and rings lubed ?? Did they have a lubricator on the air line ?? All in all a great vid of a wonderful project. I can't wait to see her under steam.
That could be run on the Romney Hythe and Dymchurch Railway in the UK. Look it up. That’s if it could get round the corners. I assume the wheels can move laterally in their bearings…
I would visit just to see that masteiece operating on air. I would continue to do so to avoid the complexity and danger of steam. Just put a big air compressor in the tender and roll away. At $100 / hr shop rate I can only guess at the cost. However much, art at that level is worth it.
That is just cooler than dirt. I don't know how you made it, or how you could afford it, but it's sweet. Will it pull another car with two or three people? That would be great. I see that it did pull another car with people. Great, sweet.
What about internal lubrication of cylinders & pistons? Does running dry break them in? It has been 3 years since this video was posted what has happened since? Inquiring minds need to know. Thanks for sharing!
@Alex Beams : Is Darrel a Dutch guy ?? is name is for sure dutch !! His name means he is a wooden shoe maker. Hope this loco gets all done in 2021 . Looks promising. Greetings from Eindhoven Netherlands
What can be the minimums for a track radius with a 12? (Actual or scale.) Or is there enough flexture between the drive wheels where that isn't so much an issue?
Depends on what power you want. If you just want to move it.. not much. Also most steamers have a cut of valve. So running on lower pressure work, but you would need more flow
What a BEAST! The amount of time and machining, not to mention cost of materials, is undoubtedly staggering... compared to my little 7.5" gauge 0-4-0, this thing is like the space shuttle or something- on a completely different level!
Would be interesting to put the aircompressor tank on the engine in replace of the boiler. Then a diesel combustion to run the whole thing. It should pack more torque than traction motors
Why not the original 3cylinder design, with Gresley balanced valves?? If it was being built to such a high level of precision, a little extra effort would make the perfect model.
If he wanted a true master piece he should have gone for the AA20 from the USSR rail road It has 2 more drivers and 2 more trailing wheels to make it a 4-14-4 however it was quietly scrapped cus it destroyed the tracks when going around curves it couldnt fit on the turntable and it delrailed oftain.
That's an incredible amount of fabrication there. At 3:18; comparing the red-striped driver with the one behind it, the counterweights within the drivers are considerably different sizes. Why is that?
That have to be one heck of a compressor... or they spent 15 minutes to pump the tank prior to set off Looking closer that is two compressors, and well, one large airtank.
If you hafta ask, I doubt you can truly understand... The tools and skills cover a wide range!! These guys are at the top of their class! I'm an old machinist. To do this they must work all day most every day. Beautiful work!! This video is three years old. A new one is available.

Now that's something you don't see every day, a steam engine without the steam or engine! What a neat view of the workings!!
Its a good way to put into perspective on how much of the engine is dedicated just to providing steam to drive those wheels
The engine is there. The boiler isn't.
@Yule Bernard Calma the boiler is the big round thing on top that turns water into steam, yes. It's missing from this unit.
technically a steam locomotive consists of an engine and a power plant, and the part shown in the video is the engine
4-12!!-2 now that will give you some friction in some tight turns
and none of the drivers are blind either.

@@JaneDoe-dg1gv I was just going to say that!
A naked steam engine. That’s something I never thought I’d ever see.
What an elegant way to test. I could watch it all day. Beautiful mechanics in motion.
As an avid 7.25"ga fan in Australia (Building a K36) I'm really looking forward to seeing this 4-12-2 Loco in steam.
Thats actually really cool. It makes sense using compressed air to test the drivers but damn! Nice!
They do the same thing on full size loco restorations as well

I was there that weekend, I saw it when it was on the trailer. I think that was the last weekend for the Arborway TT & Northwestern Railroad.
I'm surpried it goes round the curves with that long wheel base.
Would have been nice if they had gone for the three cylinder layout like the 9000 class.
It would be impossible to do maintenance on that third cylinder.

wow, a gasoline--electricity--compressed air--cylinder driven train, very impressive
I like that it’s a diesel air powered engine. They should make it a diesel/air powered engine. Way more efficient & less maintenance.

@@darylcheshire1618 the small set of cylinders are piston VALVES. this is a single expansion system quite obviously.

I would love to see a live steam UP 9000 class with all three cylinders in use.....
I don't think anyone would spend the time or money to make a 3 cylinder loco in live steam simply because of maintenance headaches
Do I see right? They use a combustion-engined generator to power a compressor to feed a steam engine? How complicated it can be?
Would love to see this full scale, build the compressor and generator in the loco. Run off some eco fuel?
It will be a steam engine when it is completed.
The back compressor is Deisel powered so the box at the front is another compressor not a generator
