The funny thing is about this locomotive due to its wheel arrangement of four leading trucks six drive wheels and four trailing trucks this locomotive would’ve been called a Hudson here in the United States after the Hudson type locomotives used by the New York central railway
Great video! I believe this loco derailed quite spectacularly at Peterborough in 1955, renumbered at that time as 60700. It is a shame the loco was not preserved, however the tender is currently preserved on a different engine.
It wasn't "high pressure steam" per se that didn't work - it was the "Water Tube Boiler" - many railroads tried water tube boilers but they were unsuccessful because they were hard to clean as locomotives use an open cycle and it was nearly impossible to provide perfectly clean water. Ships use a closed cycle where the same water is used by virtue of condensers.
The water tube boiler worked very well. It continued in service for 24 years after the locomotive was rebuilt in a more conventional form. Dedicated tools were produced for maintaining the boiler, making sure the water tubes were clear of scale. The engine as built had an issue which took quite some time to be identified. The pipe feeding steam to the cab manifold which fed injectors and so on was simply too small in Internal diameter to be able to supply the quantity of steam needed. No boiler is going to perform well if it cannot be fed with sufficient water. Once this miscalculation had eventually been identified things naturally improved. The engine remained experimental, the bore of the h.p. cylinders was changed, the engine was set up to work in pseudo three cylinder form and the high steam temperatures did lead to some materials issues but in spite of testing being carried out no one found out how to drive the engine properly. There were clues in the test results but at the time no one picked up on this. Gresley had wanted the engine to be worked with a high pressure cut-off of 70% but was persuaded by an influential academic of the time not to. Gresley however was right and his thinking was much in line with the developing ideas of Andre Chapelon - long cut-offs on the hp cylinders and adjust the output by varying the cut-off of the low pressure cylinders. It has been extrapolated that if 10,000 had been driven as Gresley originally thought it should have been (which was at odds with what he believed in his earlier days) and in conformance with Chapelon practice the engine would have been the most powerful steam locomotive in the UK by a substantial margin. Gresley used to delegate to members of his team and many of them were very good but a better man than the responsible individual from 1933 was needed to to get worthy results from this project. The NRM holds a dedicated file on this engine.
@@DeCasoU1 Nice information - thankyou. My knowledge is with U.S. made engines. We had few three cylinder engines with Gresley (e.g. the UP 4-12-2) valve gear. Gresley gear was a pain to adjust and most of these engines had the Gresley removed and a second Walschaerts or Baker gear added to one side to run the middle cylinder. American companies also hated that middle cylinder because of accessibility and the crank throw on the axel. Many tried water tube boilers but they just were not very successful with coal or bunker C oil because the outside of the tubes would coke up and were nearly impossible to clean whereas in a fire tube boiler a little sand would do the trick.
@@Hogger280 The LNER built Gresley engines retained their valve gear to the present day, only a few were experimentally rebuilt and this exercise was not repeated. Those responsible for keeping these engines running have little trouble with the valve gear. And we don't use Baker gear in the UK. Pity you couldn't resolve the water tube boiler issues, they open the door to much higher working pressures.
The one U.S. example I know of was North Pacific Coast 21, which was a wrecked 4-4-0 rebuilt into an early Cab Forward, long before Southern Pacific ever thought of the idea. It was given an oil burning water tube boiler built in-house by the Sausalito shops and while the basic Cab Forward design was sound, 21 was prone to wheel slip, due to the new boiler design having significantly less adhesive weight on the drivers than the conventional type. Also, the oil burner heads were placed too close to the steam generating tubes, which led to blistering.
i received my model train version of 10.000 hush hush from hornby yesterday....and i am pleased to say that it runs as good as it looks.....quite frankly i'm chuffed
One note about the Yarrow Watertube boiler was that after it was removed when 10000 was rebuilt, it ended up being used at Darlington Works for pressure testing. The boiler was finally scrapped in 1965 (6 years after 60700 (Which was the BR Number for the W1) was scrapped.
My Grandpa went to see this after it had been rebuilt, as it was being displayed at King's Cross. I've also seen a 5" gauge model of it in rebuilt form, which has the same steaming problems!
The Delaware and Hudson (D&H) in the US, primarily in states of New York and Pennsylvania, under the leadership of Leonor Loree, experimented with several monstrous 2-8-0s (and one 4-8-0) that had up to 500 psi in the 1920-30s. Though they developed approx a huge 80,000 lbs tractive effort, and could "couple to and pull out everything in the yard", the maintenance requirements went into orbit and they were also short lived.
Two other railroads had high pressure engines,and they were the NYC,(4-8-4),and the B&O,(4-6-4),and the B&O,used a watertube boiler,in both cases,the engines,were considered experimental,and overall didn't work out that well! The PRR,had a steam tubine,[direct drive],and the C&O,had a steam- electric drive engine,as did the N&W,so these are footnotes on some other lesser known steam failures,as they were protypes,and never led to fleet use! The PRR,bypassed the problem,by going to electrification,and that along with the New Haven's,now constitutes the current North East Corridor,(finally extended to Boston,a New Haven dream,now fulfilled)! Quite a legacy,even in this day and age! Thank you for your attention ☺!
The key difference was that this was a water tube boiler, the opposite pattern to standard firetube boilers. These work fine in ships and power stations but turned out to be less well suited to steam locomotives.
Shame to hear it didn't do well. But love those nicknames, especially "Galloping Sausage"...since Gordon in Thomas & Friends thought Duck called him one.
Pegasus would’ve been an awesome name for the W1 ‘Hush-Hush’ Baltic, had the engine survived into preservation. I still say scrapping her was a waste of potential, especially if more W1’s were built and experimented on how to improve locomotives of such design, streamlined or otherwise.
The limiting factor for the speed of a steam locomotive is the rate that cylinders can reciprocate, which passes on to the size of the driving wheels. That is why passenger steam trains had larger wheels than goods haulage, but goods haulage having smaller and more wheels had more tractive power. The theoretical advantage of HP steam locos was thermodynamic efficiency requiring less coal. The Hush Hush was designed to use 20% less coal than its equivalent express steam locos. That did not happen as hp steam proved to be too dangerous, in addition to unanticipated extra erosion on the steel piping requiring extra maintenance. The Hush Hush was run for a while but at typically express steam pressure of 220 psi. HP steam might have worked fine on ships, but proved to be a bit of a failure on locos.
I find the Hush Hush to be one of the most interesting locomotives out there. It was a neat idea for an experiment, and it looks really neat. It’s a pity it wasn’t more successful though, as it would have been really cool to see multiple of these running down the mainlines. Out of curiosity, what is the music used in this video, I really like it.
My theory is that the marine boiler does not require an extended firebox (at least not this triangular type, it was basically the same it was just as shown on the picture built narrower in order to fit the locomotive chassi) because it is constructed in a different way with the firebox directly under the pipes. The reason some American locomotives had a much larger firebox was because they used Antracit as fuel and the firebox was especialy built for antracit, wich require a much larger room in order to reach the same temperature.
@@sheep1ewe That bit about the anthracite is only true for the camelbacks, which burned anthracite culm (literally the waste material that couldn't be sold economically). The Lima-style "superpower" designs used big fireboxes for increased steaming capability from the increased grate area of a larger firebox. It's the same idea as a 4-6-2, but with even more firebox. The logical conclusion of this was the 2-6-6-6 "Allegheny" simple articulateds which had a 6 wheel trailing truck for firebox support.
@@davidfuller581 Yes, i had to chack up the differense between the British and the American meaning of the word, that make a lot more sense to me than using higher grade fuel in those areas. Interesting history by the way. Except for parts of Germany i don't realy think there are any large scale paralells to that in Europe, at least not in the 1900s. (I don't know about Russia, but i can imagine they did in some areas)
Hush Hush was designed per Gresleys thinking that he didint want it to be any more powerful than the existing A1 pacifics and he also got the design of the compounding wrong. If these faults had been dealt with it would have a powerful locomotive. there was nothing wrong with the boiler concept that a bit more work on getting the drafting correct wouldn't have cured.
What's wrong with high-pressure steam engines? LMS: [Dark Flashback] LNER: [Regret for the experiment that did not go well as expected, but still did some good effect, and did served several works for the railway, eventually]
As far as I can tell the most important quality for a high performance boiler is rate of steam production. In boilers of equivalent size their operating pressure would be an indicator of that rate. Was the hope that high pressure boiler would transfer heat more efficiently to the water? Otherwise I don't see why the higher pressure would be expected to help.
Maybe, unless they were also interested in thermal efficiency improvements, to reduce the amount of coal burnt, compared with conventional locomotive boilers.
The higher the steam pressure the greater force on the piston, allowing for smaller cylinders and pistons which means less reciprocating mass. Unfortunately, with only a single stage of expansion, efficiency would suffer as less heat is extracted per pound of steam.
@@billmoran3812 this is true, but to my understanding, full boiler pressure is not applied to the cylinders, at least in locomotives with regular boilers. Also pressure is only half the equation, steam must also be applied in a sufficient quantity. Doubling the pressure is all well and good, but if you only get half the mass of it does that actually give a benefit?
@@MainlyHuman Doubling the pressure but adjusting the cut-off to only allow half as much mass of steam would offer an advantage, if one could double the expansion ratio of the cylinder. The portion of the cylinder travel after the volume has doubled would yield the same amount of energy as had been yielded on each stroke at the old pressure, but one would add additional energy at the start of the stroke. Doubling the expansion ratio, however, would be essential, and I doubt it would have been practical for non-compound locomotives.
@@flatfingertuning727 I think that fits my understanding, for non compound locomotives at least, the mass of water converted to steam is what's significant, as you can extract that energy from different pressures by altering the cylinder conditions. I imagine that higher pressures work better for compound locomotives for the reasons you have above, and that is important because compounding (when enacted properly) can result in significant efficiency increases. It doenst make sense to build a really high pressure boiler if the cylinders aren't built to accommodate that though.
my theory of why this design failed is that in a marine environment water-tube boiler, the heat from the fire rises around the tubes and then goes up (if you look at pictures of Yarrow Boilers installed in ships, you can see that the exhaust rises straight up vertically and doesn't need to travel horizontally like in a steam locomotive). but those hot gases need to travel towards the front of the boiler in a steam loco, so you aren't getting enough actual heating area on the water tubes compared to the theoretical heating surface. Marine boilers on steam loco's have never been a success, either due to high maintenance or poor steaming ability.
@@DeCasoU1 why? does it prove me wrong? and what file? is it an LNER performance review? the steaming ability of the Yarrow designed boiler? Is it Nigel Gresley's thoughts on how he overcame some of the potential issues I stated?
Diesel: Hey guys, look! It’s the Galloping Sausage! Gordon: Really, Diesel?? I thought you learned your lesson a short while ago. Diesel: No, Gordon. Look. LNER W1 Class: Hi, I’m the Galloping Sausage!
The Virginian 2-10-10-2s were very efficient and effective low speed heavy duty haulers in the mountain coal field service in which they worked. The same could NOT be said for the infamous Virginian 2-10-10-10-2 Triplex w/ the last driver set under the tender. As tender load used up that set drivers lost traction and slipped excessively. Far worse was the boiler capacity that could not keep up w/demand and they ran out of steam routinely before getting to next station down the line!
@@MatthewChenault Touche! Got hung up on the number 10! Several other roads tried putting drivers under the tender (one was NC&StL w/a 2-8-2+2-8-0 combo) that had similar results. If course Virginian eventually solved its worst grade problem w/electrification then ultimately dieselization w/the Fairbanks Morse Trainmaster units (2,400 HP each I believe).

What's wrong with high-pressure steam engines?
LMS: [Dark Flashback]
LNER: [Regret for the experiment that did not go well as expected, but still did some good effect, and did served several works for the railway, eventually]
The boiler still exists at Darlington
Apparently the LNER predicted the “Galloping Sausage” name, not Diesel.
There is a very angry A3 Pacific named Gordon on his way to yell at you now 🤣
As kids we called it the "Unnamed Streak" - "Streak" being the nickname for the A4s.
He called me a galloping sausage! Rusty red scrap iron, replied James. And he called me old square wheels!
Gordon: GALLOPING SAUSAGE!!! I have never been so insulted in my entire life!!
So did it have a water tube boiler?
"He called me galloping sausage!"
-Gordon
Oh nice, for once the algorithm gave me something I actually liked for a change!
Very good
Ahh, so the British Hudson. Nice
Would that boiler have worked better with a steam turbine engine?
“Weirdo”
-this was made by the normal locomotive gang
Edit: also Gordon used to be an LNER loco and he was called “Galloping Sausage” later on
As far as I can tell the most important quality for a high performance boiler is rate of steam production. In boilers of equivalent size their operating pressure would be an indicator of that rate. Was the hope that high pressure boiler would transfer heat more efficiently to the water? Otherwise I don't see why the higher pressure would be expected to help.
Maybe, unless they were also interested in thermal efficiency improvements, to reduce the amount of coal burnt, compared with conventional locomotive boilers.
The higher the steam pressure the greater force on the piston, allowing for smaller cylinders and pistons which means less reciprocating mass. Unfortunately, with only a single stage of expansion, efficiency would suffer as less heat is extracted per pound of steam.
@@billmoran3812 this is true, but to my understanding, full boiler pressure is not applied to the cylinders, at least in locomotives with regular boilers. Also pressure is only half the equation, steam must also be applied in a sufficient quantity. Doubling the pressure is all well and good, but if you only get half the mass of it does that actually give a benefit?
@@MainlyHuman Doubling the pressure but adjusting the cut-off to only allow half as much mass of steam would offer an advantage, if one could double the expansion ratio of the cylinder. The portion of the cylinder travel after the volume has doubled would yield the same amount of energy as had been yielded on each stroke at the old pressure, but one would add additional energy at the start of the stroke. Doubling the expansion ratio, however, would be essential, and I doubt it would have been practical for non-compound locomotives.
@@flatfingertuning727 I think that fits my understanding, for non compound locomotives at least, the mass of water converted to steam is what's significant, as you can extract that energy from different pressures by altering the cylinder conditions. I imagine that higher pressures work better for compound locomotives for the reasons you have above, and that is important because compounding (when enacted properly) can result in significant efficiency increases. It doenst make sense to build a really high pressure boiler if the cylinders aren't built to accommodate that though.
I wonder what a steam locomotive designed with modern tools and techniques would look like
"Galloping Sausage?! Humph!"
The inspiration for Gattor in Thomas and friends movie
"Fury didn't work out so well'..
Understatement don't cover it......
Ta.
my theory of why this design failed is that in a marine environment water-tube boiler, the heat from the fire rises around the tubes and then goes up (if you look at pictures of Yarrow Boilers installed in ships, you can see that the exhaust rises straight up vertically and doesn't need to travel horizontally like in a steam locomotive). but those hot gases need to travel towards the front of the boiler in a steam loco, so you aren't getting enough actual heating area on the water tubes compared to the theoretical heating surface. Marine boilers on steam loco's have never been a success, either due to high maintenance or poor steaming ability.
Go and look at the file in the NRM.
@@DeCasoU1 why? does it prove me wrong? and what file? is it an LNER performance review? the steaming ability of the Yarrow designed boiler? Is it Nigel Gresley's thoughts on how he overcame some of the potential issues I stated?
@barnabyjoy Interesting insight from someone with a working model
@barnabyjoy Huh, so I had the right idea, just the wrong information. My theory was wrong. Thank you for this helpful information
Diesel: Hey guys, look! It’s the Galloping Sausage!
Gordon: Really, Diesel?? I thought you learned your lesson a short while ago.
Diesel: No, Gordon. Look.
LNER W1 Class: Hi, I’m the Galloping Sausage!
So wait thats a water tube boiler or a fire tube boiler?
How about one about a stream engine turning into a stream generator?
The boiler and firebox just look like cellulite to me!
Looks like Gordon to me
Speaking of locomotives that worked, but weren’t practical, let’s talk about the Virginian’s 2-10-10-2.
The Virginian 2-10-10-2s were very efficient and effective low speed heavy duty haulers in the mountain coal field service in which they worked.
The same could NOT be said for the infamous Virginian 2-10-10-10-2 Triplex w/ the last driver set under the tender. As tender load used up that set drivers lost traction and slipped excessively. Far worse was the boiler capacity that could not keep up w/demand and they ran out of steam routinely before getting to next station down the line!
@@kenhanks9620, you mean the 2-8-8-8-2?
@@MatthewChenault Touche! Got hung up on the number 10!
Several other roads tried putting drivers under the tender (one was NC&StL w/a 2-8-2+2-8-0 combo) that had similar results.
If course Virginian eventually solved its worst grade problem w/electrification then ultimately dieselization w/the Fairbanks Morse Trainmaster units (2,400 HP each I believe).
The galloping sausage? Uhmmmm a hotdog fan would really be terrified of that naming on a big engine like this
Seemed like it would be impossible to see anything forward.
Was this locomotive the predecessor of the mallard?
Now if we got get the origins of 'Rusty Red Scrap Iron' and 'Old Square Wheels'.
Gordon:*sees this vid* a galloping sausage! *then Gordon killed dissel*
Duck called me a galloping sausage - Gordon
“Why does every main engine on Sodor have to be some bizarre one-off prototype, does anyone else have a problem with that?”
- the funni Tugg with bad lucc
( well, maybe the Galloping SUSage was the reason for it, I don’t know, seriously why didn’t Awdry just make Gordon this? )
10000 was also a compound.
" doing its work with underwhelming results " That sounds ominous.. what did go wrong ? - The high pressure boiler being vulnerable to limestone in the feed water ?
Next do the ger class a55
I can imagine Spencer or Mallard being jealous of "Hush-Hush"
The most funni loco 😂
That boiler looks very, uh... phallic.
me as a kid: "heh gordon saug"
me now: "ooh~."
Galloping sausage? That was my nickname in highschool
