      @@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.

    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.

      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.

    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.

    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.

      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.

    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.

    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
      @michaelmcnally2331 หลายเดือนก่อน +1

      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”.

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?

    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.

    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.

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.

    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!

    I'm just gonna come out and say it, because I think everyone's been afraid to thusfar.
    Steam trains should be using water-tube boilers, not fire-tube boilers.
    Water tube boilers are much more lightweight, and they capture the heat energy of the flue gases much more efficiently.
    Water tube boilers are a supremely well understood technology, there's little about them that we don't know.
    They were never used on locomotives, but they WERE standard issue on another type of steam-propelled vehicle. US-navy steam turbine powered warships of both world wars used water-tube boilers.
    These are MUCH more efficient and much lighter than fire-tube boilers of similar capacity.
    They have the steam output to actually support a steam turbine prime mover, something fire tube boilers can not do. Switching to a water-tube boiler and a steam turbine would entirely eliminate any hammering on the rails that a piston steam engine's connecting rods might induce by the nature of their offset mass, and you can quite easily connect the steam turbine directly to an electric generator, making the locomotive able to use the existing electrical technology such as traction motors bogies generators and switchgear of Diesel locomotives, while also allowing easy conversion to a fully electric locomotive if local infrastructure has provisions for such.
    The water tube boiler has additional advantages, it's more fuel efficient AND more powerful than a fire-tube boiler of the same operating mass (there's a balance to be struck, fuel efficiency can be traded for power output and vice-versa to a degree), and this is the primary reason why a steam turbine is viable in the first place.
    You can even have these water-tube boilers be oil-fired, meaning they can use the existing infrastructure that supports Diesel locomotives.
    Thermodynamic efficiency of a steam turbine can be higher than even a Diesel locomotive, at least in theory.

  • @henryostman5740
    @henryostman5740 หลายเดือนก่อน

    The answer is very simple, the Diesel. Rudolph was on to something, he wanted higher efficiency and he got it. Steamers have a thermal efficiency of less than 10% while Diesels often can exceed 30%. Note that there are no steamships either, another win for the mighty diesel. Mind you, I love the complications of the steamer, boilers, the mechanical complexity of the whole thing, the noise and smoke, the sound of the whistle, all great things. The diesel just goes about business getting the job done like a good appliance, no drama. Ocean going steamers really weren't very practical until the development of the triple reduction engine design, they used too much fuel and water before that. The Titanic went one step further with a low pressure turbine using the exhaust steam from the outside engines to power a centerline propellor to get the last bit out of the steam. The Mallet, a double reduction design saw very limited application in the US, it was a great design but the rail shops didn't like it, too complicated, but it got two uses out of the steam. The brits built a number of rigid chassis locomotives with high pressure cylinders driving cranks on the front axles and low pressure cylinders on the outside looking like a conventional locomotive, mechanically complicated but going in the right direction. These served well into the sixties on british lines. The brits had other designs used on colonial railways that put more of the locomotive weight on the drivers unlike the Pennsy's 6-4-4-6 design that put 60% of the engine on the pilots, why not build a 4-6-6-4 instead. OK, for fun the steamer is by far the most interesting but if you are running a railroad and want to make money doing so, buy diesels.

    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.

    I look constantly at ATM's to see if anyone was too impatient to grab their cash, but no luck yet. Puffing Billy Railway in Victoria Australia has converted one of their NA 2-6-2 tank locos to burn oil but not heavy oil as it often the case. This conversion is to burn light oil or distillate and the burner looks like a large domestic gas stove with four large burners and a small central burner arranged like the white dots on a dice representing the number five. They run through a forest and often have to have a small water cart train following the main train to look for spot fires started by flying cinders. The diesel fuel means no need to look for a new supplier of fuel as they have diesels already. The whole burner system is Swiss designed. Maybe the UK could look into it for it means no flying cinders and no coal to buy or coal ash to get rid of. Yes the smell of coal is nice but having locos running on the mainline even if oil fired is better than no steam locos running on the mainline. Unlike other steam locos that are oil fired, the NA Puffing Billy Loco doesn't produce clouds of black smoke even when working up steep 1 in 30 grades.

      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.

    The steam vs. diesel tests conducted by the New York Central Railroad in 1946, between new Niagara-class 4-8-4 locomotives and new EMD E7 units, showed that modern steamers could compete quite successfully on an operational cost basis with diesels. But a variety of factors led to the dieselization of most American railroads by the late 1950s, and the Niagaras were all scrapped in 1956.
    The American ACE 3000 was a proposed modern 4-4-4-2 coal-burning duplex-drive steam locomotive design for Ross Rowland's ACE 3000 Project for the American Coal Enterprises, proposed in the 1970s. Like the project in the video, sufficient funds could not be procured to build a prototype locomotive.
    I'm a mechanical engineer, and I firmly believe coal-burning steam locomotives could be built that could still compete with diesel-electrics today. However, the political climate surrounding "climate change" would probably not allow it.

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. Not sure Wardale had much experience there
    Now what I’m surprised no one’s tried is a Live Steam model of the 5AT

    • @DeCasoU1

      The 5AT was designed to weigh 80 metric tons and produce an indicated output of 3,200 hp at 113 km/h with a maximum operating speed of 180km/h. How many class 6P or 7P can equal this level? The answer is none. The design was based on that of the Std 5 because it was an accepted and understood type which made dealing with the responsible regulatory bodies far more straight forward. Why was the build not feasible given that the creation of new members of lost designs has been going on for some time now? Wardale learned from Porta who learned from Chapelon and though AXC did use poppet valves on some designs he reverted to piston valves on his later engines for good reasons. Porta would not consider the use of poppet valves since they offered no advantages over his piston valve design. You could build a very different locomotive than the 5AT; say a water tube boiler type with a working pressure of 32.75 bar and triple expansion compound drive. It would be a fascinating project but it would be very expensive and your chance of being able to run it would be very low because such a type lies well outside existing experience.

    L.D.PORTER & DAVID WARDALE - THE ADVANCED STEAM LOCO.
    There appears to be a fundamental misunderstanding as to how L.D. Porta & Wardale fit into the picture. And in particular what L.D.Porta (who was the mentor) was after. "Increased power" was a fundamental bonus of the primary target of Porta's work. Which was to increase the efficiency of the steam locomotive so as to make it MORE efficient than the Diesel !!!! The "Red Devil" of SAR was effectively Wardale applying what L.D. Porta had explained to him would be the way forward. Porta it must be realised was involved in a number of projects worldwide, including in non-British speaking countries including Spain.
    Having watched a Video of Porta in Lleida Spain, explaining the sensible improvements for a preserved Beyer Garratt. None other than a British built broad Gauge (5ft 6in) 4-6-2+2-6-4 EXPRESS type Garratt, to the person in charge of the loco (nicknamed the "Carrot" because of his red hair). It became sadly evident that the Spanish "Carrot" had no comprehension of the radical changes to that Garratt that Porta was explaining. As a result that Garratt, the last express type on the planet, is not fully restored. The Carrot, had to repair the firebox, so the idiot cut through the main frames so he could slide the firebox out sideways to repair it. Simply because the roof in the building where the loco was housed was too low, to lift off the boiler ! Having then realised this is not a clever idea, he put the firebox back into the loco "unrepaired", and welded the mainframe back up, and carefully hid the fact by machine polishing the weld marks. So the loco still resides in Catalonia, Northern Spain in a part rebuilt condition.
    Porta also aided Roger Waller of SLM Winterthur in the serious modernisation of an ex German WW2 (Class 52) 2-10-0. This loco was effectively the culmination of Porta's work. And proved it was more efficient than the Diesel. This 2-10-0 loco was rebuilt with low emission output (using light diesel fuel), modern thermal insulation techniques, "total automatic self lighting up", one man operation, full roller bearing on wheels and coupling/connecting rods, & a more efficient valve gear. The onus being on removing the expensive manpower numbers normally required simply to prepare a steam loco for work, and further manpower to operate it. Which effectively requires around a dozen people just to prepare & operate one large steam loco for a days work!!!

    In addition to your planned improvements in the steam engine design, have you considered the many benefits of designing a hybrid electric steam locomotive which can generate stored electric power when not applying tractive effort to the main drivers? One can design an engine which utilizes large driving wheels for speed while the acceleration would be boosted by electric traction thereby solving a problem which has plagued traditional steam locomotives - getting started. It should be capable to utilize regenerative braking and should be capable of running on electrified and non-electrified tracks, thereby eliminating the need to switch locomotives on routes which have partial electrification. With Amtrak hoping to increase and enhance rail service in the U.S. over the next decade, this would be a good time to promote a sustainable mode. Hybrid modality has improved the petrol powered automobile, virtually doubling its efficiency; why not for the steam loco?
