What happened to the FUTURISTIC steam locomotive?

[@theaccountofmine.8779]

I like how you say “puffing in an exaggerated manner” while footage of a manor plays in the background, cheeky that.

[@LBSC70]

Why do Great Western Engines make a ticking noise whenever they are puffing under their own power, Halls, manors, panniers, prairies, 14xxs they do it

[@ChristheXelent]

​@LBSC70 it's just the nature of the valves on Western designs

[@LBSC70]

@@ChristheXelent Ok thanks

[@BrokenIET]

@@LBSC70The ticking is the anti-vacuum (aka a “snifting” valve). They serve the same purpose as a small ejector but without wasting steam. They only actually help remove the brake when the loco is going over about 15-20mph though which means that the large ejector has to be left on if the train is going below that speed, which is the only major drawback.

[@ChristheXelent]

The main problem the 5AT has always (sadly) faced is that no major investor has much faith or interest in an excuse to reinvent the steam locomotive for the 21st Century. Given how advanced electric traction is now, there’s pretty much no going back. Awesome as it would have been to see, the idea is more or less dead and barely talked about nowadays. The Advanced Steam Traction Trust are more focused on developing better forms of biocoal than reinventing the engine itself.

[@kaydensrailway5594]

I believe that what the 5AT group should’ve done from the beginning was approach owners of existing Black 5s and Standard 5s to work on and improve their locos first, and then, once the results build trust with the public, pitch the idea of the 5AT.

[@SalmanMentos]

The best reasonable excuse for reinventing steam locomotives is hydrogen power since it creates 0 emmisions* Even tho it may just be another gadgetbahn many people think the future is cleaner technology (like those tesla triangle cars even if making those batteries hurts the envoirment)

[@AndrewHager02]

Meanwhile, in New Zealand, there’s a guy doing hands on engineering to try his hand at advanced steam technology, he goes by Sam Mackwell. You guys ever heard of him?

This was an instant must-watch for me. The 5AT is one of my favorite big engine concepts ever. And if it were somehow built, it may well have been my favorite big engine ever (I say big engine bc the LB&SCR E2s are still my #1). Like us Yankees' very own PRR S1, the 5AT would have pushed steam to its limits. I really hope one day someone with the cash and guts takes the leap to answer the what if. Those are the best kinds of questions. :D

It would be an injustice in any discussion of modern steam to not mention the mackwell locomotive company, who have created a far cheaper, easier to maintain, more powerful, risk free, net zero emission boiler and are currently in the process of developing a steam tractor for the agricultural market.

[@eliyahzayin5469]

I actually talked about the 5AT in comparison to other newbuild and modern steam groups for a college final! My rough take on it was that Wardale unfortunately didn't do a good job at finding a core group to pitch to. Unlike Tornado (and other semi-traditional new builds) the 5AT couldn't tie into a preexisting history while at the same time it was often too traditional for a lot of the people interesting in modern steam (Reading through the 5AT website's FAQ and Duke team correspondence is rather painful) (ETA) To be more precise, while there haven't been any super successful modern steam groups, there are a few that got further off the ground, and they largely did so by having a very very specific reason to exist. For example, DLM in Switzerland is built on a brand of 1) environmentalism and 2) making the operation of steam locomotives more friendly to every day use--the crown of this being their German Class 58 rebuild that has a cab experience comparable to an electric locomotive. Newbuilds have gained even higher success from focusing on resurecting lost classes rather than targeting an intentionally modern design. However, modernizing/improving has often set as a necessity, especially for unproven designs like the PRR T1 and Gresley P2 (Which, since both these designs relied on poppet valves, ironically means that two groups working to rebuild OLD designs are actively developing/improving a much more modern valve gear than what Wardale wanted for the 5AT) The impression I've gotten from the 5AT website and most of it's press was that there wasn't any real reason for it beyond 'modern steam locomotive.' There was talk of it for the heritage sector but also talk about sending it (or at least a variation of it) to third world countries that still rely on coal. I really don't think WHO they were building for was very well thought out and with the combination of trying to find a traditional investor rather than what the A1 trust did was the main funding killer. I am excited for the Revolution Project that the Advanced Steam Traction Trust has been currently doing, as it feels more grounded and (because they're starting with a mini-gauge prototype) likely to succeed.

[@KibuFox]

Back around 2007-2010, I did some contract work with Wardale to render it into 3D. Part of the reasoning being that he wanted to have actual working (as in rigged/animated) design models of various parts of the locomotive design, and then a fully rendered model of the locomotive and all its variants. There were actually quite a few more than people knew about. Whatever the case, he sent me copies of his various design elements, and over the course of a year, I modeled and rendered about half the model, before I started running into problems. Some aspects of the design that he wanted to incorporate, while they made sense on paper, actually wouldn't work in practice. For example, he planned to have a curious 'double' valve gear on the pistons. Not unlike the Vauclain compound locomotives, where you had a low pressure, and high pressure piston contained in the same piston cradle. Not a piston inside the frames mind, but two pistons built in one that worked off a singular drive rod. Rather than taking the previous design element that had been used with Vauclain Compounds, he'd instead created this strange system with two eccentrics, and two completely separate valve systems. During rendering of that part, it became painfully obvious to me that there was no actual way to make that fit within the design constraints he had placed. This prompted him to redesign the piston system, completely removing the odd compound pistons in favor of a more conventional piston and valve gear system. Though in many of our discussions, he noted that if I could figure out how to make it work, he would have much rather I continue with that design element. I remember informing him that while I could 'make it work' in theory, since I wasn't an engineer, I couldn't guarantee that any modifications I made would actually work in real life. After all, I was a simple 3d rendering artist, and any modifications could potentially break the laws of physics. The final engineering renders were delivered to him in early 2010, around March I believe, and featured a rough outline of the streamlined, and non-streamlined variant; with two tenders. The first tender being a conventional coal fired tender, and the second being a proposed diesel fuel tender, both built roughly along the same lines of a black 5 tender, though with some of his own proposed modifications. I expected to continue working with him on the project, but at that point he was already questioning whether or not it was even plausible to continue the project. By 2012, as we all know, the project had been abandoned. I believe I still have some of those renders somewhere on a hard drive, though I'd have to find them. I have often thought about going back and uploading them for history's sake, though I'm not certain what if any good they could do for people.

[@eliyahzayin5469]

Woah! Regardless of what you do with the models, that certainly sounds like an honor. It is curious to me though why he wouldn't have someone working on making a CAD model, as that is usually the standard for modern engineering. I know the tech has been around since the 80's but I suppose that it is possible that actual ability not just make parts but assemblies in CAD wasn't quite there yet.

[@trainworms]

would be cool if someone could use them to build models from.

[@the_retag]

We know some about how modern steam engines perfom. Meiningen works together with dlm/slm in the nineties built a series of rack locomotives based on an old class but completely revamped with modern steam tech. One man operated, electric preheaters etc.

[@lordrindfleisch1584]

The problem with steam is a fundamental one. A steam engine has to carry fuel and (a lot of) water. A diesel engine only needs to carry fuel and electric locos dont even need to carry that. There is simply no way around that

What about a nuclear powered steam locomotive? It sounds great, doesn't it?

[@toyotaprius79]

Honestly I daydreamed of this too many times, if any of us had a shot at it and develop a 21st century steam loco it would have to have a mix of electric and steam propulsion, it would be mixed fueled for both solid and liquid fuel burning. Going further it would use those compact +10,000psi pressured steam generators used in steam cars from the 1920s but losing the loco's inconic horizontal boiler. Given that battery electric EMUs and shunters existed in the 1920s as well like the Drumm trains of Dublin, it seems like a missed oppertunity that the inefficiencies of warming up and the wear'n'tear of starting and stopping heavy trains weren't complimented by a battery-electric regen "accumulator" system. While on the other hand steam performs best at constant speed which is the absolute opposite for electricity. Hell we've had several decades of Diesel dynamic braking wasting electricity into heat before anyone bothered to harvest that energy with batteries.

[@1471SirFrederickBanbury]

oil burning steam turbine electric, with maybe a small booster engine for goods, and a more normal steam engine with auxiliary electric motors is what I'm thinking of. That way you get most, if not all of the advantages of diesel electrics, but you have the grunt power and top end performance of steam.

[@ALCO-C855-fan]

Forget reviving main line steam. Technology is further than that. Also the cost issue will never be solved cuz - economy + it alienates railways. I'd love to see it happen, but the steam age simply ended with the combustion engine and stuff like solar and hydrogen could replace the Diesel as well soon.

[@Trainskitsetc]

There are problems looking for a solution and there are solutions looking for a problem. 5AT is the solution looking for a problem. Simply put, no matter how much you refine it and tinker you will not match diesel or electric(especially once the faults were ironed out) cost effectiveness and ease of operation. Steam ain't coming back. Also mainline steam design continued well after the 9F, which was designed in the early 50s, just off the top of my head the QJs in china were designed and built later than this. Other examples exist as well.

[@grahamariss2111]

The performance improvements sound good until you take into account the appalling thermal efficiency of a steam engine, this design has a thermal efficiency of 14% whilst a modern diesel locomotives are bettering 50%.

[@justandy333]

I love the story of The Duke of Gloucester. An experimental design brought in to replace an engine that was totalled during the Harrow and Wealdstone Rail disaster. A perfect albeit morbid opportunity for Riddles to produce a new locomotive. However due to some design oversights (there's a bit more to it than that) it was an incredibly poor performer. Hated among the crews that had to operate her. She was sent for scrap after 8 years of service. The hulk was eventually rescued from Barry scrapyard and restoration began. But what sets this story apart from many others is that alot of time and effort was put into rectifying the issues that plagued the Duke whilst in service. After restoration was completed, it was one of the most powerful and best performing engines ever seen on UK metals. Numerous speed records were smashed and firmly cemented its place in preservation history. Had British Rail had the foresight to invest in further developing this design, who knows what doors may have opened for prolonging steam in the UK? A really interesting story if you fancy a steam deep dive.

[@michaelmcnally2331]

A lot of that performance was due to the perception of the Duke being a “Big Brit” and he crews treated like a Brit which was a 2 Cylinder design. One of the crew wrote into steam railway saying that he didn’t have trouble with the Duke, however he had recognised the Duke as a 3 Cylinder and so had fired the Duke as would a Royal Scot which was also a 3 Cylinder. Provided the power he needed and didn’t struggle to steam. Was only built as Riddles desperate to produce an a express Engine and the destruction of Princess Anne gave him an excuse. Without the crash then would never have been built. Much of what was found by the preservation group was not so much the design in itself was bad, but when had been built then the design had not been followed, and those build flaws have been corrected. However by the time the Duke was out then BR already made the decision with the Diesel/Electric move so nobody had been interested in spending time on sorting out what was going to remain a “one off”.

[@LMS2968]

Actually, the engine in the Harrow accident was 'totalled' so that the 'experimental design' could be brought in. Riddles had 71000 built without authority and then had to find a space for it. Since no-one wanted it, he then created a vacancy on the LMR by withdrawing 6202. The accident happened in October 1952. 6202 was withdrawn May 1954. 71000 entered traffic May 1954. Coincidence?

If we hadn't gone the diesel route, the plan wasn't better steam engines, but electricity. That's why the standards had a 40 year lifespan.

[@marrrtin]

I have been thinking about methods to supply steam which do not involve fossil fuels such as small modular reactors and steam generators, or some other idea not yet thought, Such a system, if it could get over its own concerns, could make steam viable as low cost and emission free. The extra torque provided by steam should still have many uses. And if any loco frame could be suited to this endeavor, it would be the 5AT.

[@1471SirFrederickBanbury]

the 5AT project would've been wonderful, but I don't think that those power, tractive effort, and speed goals are at all beyond a Gresley A4, especially if given a Lempore exhaust. Considering how 2509 SILVER LINK did on her first day without a special exhaust, at a low regulator setting, the only thing stopping SIR NIGEL GRESLEY from repeating that and breaking records is the signaling equipment and regulations, the former of which has been done for big boy 4014 already. I say give SIR NIGEL GRESLEY a lempore exhaust, maybe lightweight con and coupling rods like her originals, and we have the winning idea, far easier and cheaper than a complete new build, though a bit more maintenance heavy, and slightly less efficient.

[@04clemea]

I don't know why you didn't mention No.71000 ? That's literally the peak of steam advancement and has shown what you could do with boiling water. It kind of made the 5AT project obsolete, as the 5AT wouldn't improve on performance or possibly cylinder efficiency over the Duke. Be interesting to see how well it goes during its next ticket. Future vid?🤔

[@poshdan4071]

Probably because it wasn’t a good runner when it was built. Granted it’s had improvements made to it in preservation

[@04clemea]

@poshdan4071 regardless of it not being quite upto scratch when built, it still had the highest cylinder efficiency ever recorded and then has gone onto show how well it does work. As I said in the comment, that because 71000 had shown how good it is, it kind of made the 5AT project redundant. It definitely should've got a mention or a segment.

[@tavtwo8581]

As much as this would've been incredible to see, I just don't think it ever would have been a big enough improvement to justify the project. Sure, the loco would've worked very well, and in terms of power, speed, reliability and efficiency would've been an improvement over existing steam designs, but it still has most of the major, inherent design faults of any steam locomotive: 1. It still requires two crew members (driver & fireman) to operate it, doubling operating costs. Diesels only require a driver. 2. It still requires said crew members to turn up at six in the morning to light the fire, and still be on duty well into the night to dispose of the fire once the running is finished. With a diesel, all you need to do is press the 'on' button, and press the 'off' button. (A simplification I know, but overall still a lot quicker than steam). 3. It still has all of the oiling points. Whilst the fireman is lighting up, the driver still has to go around and oil up all of the motion. Whilst a diesel driver does still have to oil up certain parts of the loco, the process is much simpler and quicker. 4. It still has a tender. You are still dragging around an extra wagon with the fuel, adding weight that is not present with a diesel. And of course this also necessitates the reintroduction of turntables. 5. It still has a long boiler at one end, and a long tender at the other. Visibility in comparison to a diesel with cabs at either end is incredibly limited. 6.It still has a boiler that undergoes incredible stresses during operation. This means both that there is a higher risk of a potentially catastrophic explosion, and of course the 10 year boiler ticket would necessitate overhauls, meaning potentially years out of action every decade each time the ticket expires. 7. It still has a fixed wheelbase, which would limit the tightness of corners it could go around. 8. It still has the hammerblow effect of the pistons on the rails, meaning increased track maintenance compared with diesels. 9. It still burns oil/coal, which as we all know are fuel sources both damaging to the climate and becoming harder and more expensive to source. It's important to remember that when diesels came along at first they were very often inferior in terms of speed, power and reliability to their steam predecessors. However, they were specifically introduced because they did away with all of these inherent steam loco flaws. And of course, modern diesels and electrics are generally far faster, more powerful and more economical than the best steam locomotives, so I don't see how this steam loco would ever be able to match them. I absolutely love steam locomotives and will always prefer the drama, noise, smells, sights and soul of them over the bland, boring, soulless, plastic boxes on wheels that rule the main line today. However there was a very practical reason for the replacement of steam in the first place, and I just cannot see how the 5AT could have possibly improved on the efficient, quiet and practical trains of today. That being said it is still a very interesting topic and one that people can (and will probably) debate for many years to come!

[@warrior3456_]

[@TheEerieMaster]

I love that beautiful concept art of this potential locomotive... Steam is one of those classic forms of energy that I believe has a lot of unforseen potential... But I'm not a engineer, so, eh

[@LMS2968]

The problem with the 5AT was that it was neither on thing nor the other. The claim of 'advanced' ignores that, in reality, it was just another development of Stephenson's 'Rocket'. A fuel-fed boiler provided medium pressure steam to reciprocating pistons via axle driven valve gear directly driving large coupled wheels, everything controlled by a driver situated in the middle with poor visibility in both directions. There were detail improvements - big improvements - but the underlying principles were the same and the same drawbacks and problems were built in. It had no appeal to those who wanted to advance rail technology; in many ways Bulleid's 'Leader' of the mid-1940s was further ahead, unsuccessful as it was. But hit had new ideas. On the other hand, the 5AT came with no history or even pretentions of history so had no appeal to the traditional railway enthusiast. Quite simply, no-one wanted it.

[@Railhog2102]

I think the best concept idea for a modern steam engine would be using heaters to heat the water to make high pressure steam kinda like those electric teak kettles u can get a the store that would use just water and a heating eliment to make steam with out oil or coal needed as when the steam goes threw the stack it just simply becomes vapor that evaporites and that is my ideal idea of what the future steam train would look like and could be ran automusly using ai and navigation to make it as effciant as possible

[@obelic71]

As most modern steamengines goes we have to look at the French. The most technological advanced steam engines who ran in revenue service were French engines designed for the SNCF. Class 232 U.I. had rollerbearings like post war German engines, an automated coal stoker like American engines, high pressure boiler like some experimental UK engines had and an unique French fully automated compound system for the cillinders. Steam engines are unbelievable powerfull but to creating the steam in energy wastefull small steam boilers killed them of . Modern electric locomotives are in fact indirect steam locomotives. Most electrical power comes from power plants who create their electric with steam turbines who get their steam form massive efficient steam boilers.

[@22pcirish]

[@russellgxy2905]

A full scale build of this is probably not feasible, at least not as a _5_AT. Headways seem to lean more towards 6P or higher these days. I recall the 5AT was proposed to use British-Caprotti valve gear at one stage, which I think would’ve helped a lot for a career in passenger use.

I've never been convinced. Streamlining has no effect below 70 mph, and a BR Class 5 has no need for a big tender. I don't believe for one minute that it could have reached 110 mph let along 130 mph.

With only 14 per cent efficiency (which is good for the steam cycle) it is just an expensive toy. Interesting to keep the technology alive but it has been superseded.

Look up the PRR T1 5550, she's getting (re)build. That type of engine, might have created a whole new type of setup. As for that 5AT, it needs a walk true tender. And look at the Mallard, way better streamlining. The 5AT does remind me of a DR locomotive that was constructed from two other locomotives, painted black, in German style. So somebody might have talked to that guy, back then. That or some spying. So she might actually, already exist, funny that, right? Might want to look at the Triplex locomotives, but using a reverse drive mallet & a Garrett, to get a true triplex. Weight of the boiler needs to rest on all drive wheels, to make a Triplex work, with the mallet drivers house, becoming the classic Garrett nose mounted water tank. Even lets you streamline her.

We whould've been trying to make them environmentally friendly (as we should)

[@simonduhamel7843]

This project is regressive in relation to Chapelons projects. he isn't even mentioned!

[@StephenMitchell-g9e]

Yes, he may well be the greatest. A book by Colonel Rogers entitled "Chapelon : Genius of French Steam" explains his achievements. His 240P was an astonishingly good performer. I think that the book has been reprinted, and I recommend it.

[@rogerking7258]

Agreed. Chapelon is really the only person to have _actually_ produced massive efficiency and performance improvements by modifying existing engines. I believe he did this with a thorough and scientific understanding of thermodynamics and gas and steam flow. It's a shame he was never given the chance to produce a "clean sheet" design because what he _did_ produce was actually an embarrassment to France's new electric locos which had to be uprated to save face. We can only speculate what he might have achieved with modern computers and CFD software. Even so, it is unlikely that steam could ever be made as efficient as modern electric traction.

Need a multi millionaire or billionaire like the waisters Elon Musk, Jeff Bezos, Mark Zuckerberg, Sir James Dyson or Sir Jim Ratcliffe. Or maybe Richard Charles Nicholas Branson.

I saw SO60 from the Derail Valley =)

[@bluebear6570]

It´s a pity you have no knowledge of railways and their engines! If you had, you would know that the efficiency of external combustions engines will always be way below that of internal combustions engines and that the unsprung masses of the valve gear put a strict limit to the speed of a steam engine of conventional design. If there was ever a chance for steam engines to stay "modern", it was destroyed at Ft. Eustis in the USA in 1951, when the stolen class 19 steam motor engine was scrapped.

12:14 Sooooooo there may be a chance that some Engineers on the PRR pushed their locomotives in the Midwest to speeds of 140 MPH… And they didn’t report it to not get in trouble

cope...

[@Skyehye3113]

To be fair I think we do need to talk about the environmental aspect of what burning fossil fuels does as much as I love steam trains deep into my soul I think unless they could find a way to make them carbon neutral there’s no way we could justify using steam engines in modern day
