The FAILURE Of This EXPERIMENTAL Locomotive 

Loving this new channel! Your editing is superb. Can only imagine how much time and effort goes into these

Another less known fact if I’m correct, The Hush Hush’s corridor tender now is being used by LNER A4 Union of South Africa

Truly the only "experimental" British steam locomotives that not only worked despite having all sorts of radical design departures but succeeded in every way was the late Oliver VS Bulleid's Merchant Navy Pacifics, his West Country Light Pacifics, and Battle of Britain Light Pacifics in their unrebuilt form. Yeah they had a few quirks but despite everything, they did their job and did it very well.

I remember seeing 60700 at Cambridge in 1950 and being stunned by the size of the cab! What was 60700 doing in Cambridge, I hear you ask? An early morning stopping service from Kings Cross was used for running-in locos which otherwise exceeded the route availability. It came in at 8.30 a.m., and we would cycle down to the cattle market (long gone!) to spot the "ex" as we called it before hastily returning to the Perse School (then on the corner of Hills Road and Gonville Place).

It was a marine Yarrow water tube (not fire tube) boiler. There were several attempts pre-war at high pressure boilers. The LMS built Fury on a Royal Scot frame. It burst a tube, emptying the firebox and killed a crewman. (I remember seeing that loco rebuilt conventionally as British Legion while in Crewe paint shop in 1959).

I see why Gordon would be offended when being called a galloping sausage

There’s a lot to unpick here but the W1 was actually a very successful prototype, and needs to be seen in that context. The water tube boiler was an excellent piece of design and later setups with enlarged receivers and the double Kylchap made the locomotive more than an equal for the A3 Pacific. It never had “steaming issues”- I am not sure where you got that from. I would suggest having a look at William Brown’s book on the W1, costly but an excellent volume and well worth reading for a more accurate interpretation of the locomotives abilities.

I have read about the W1 'Hush-Hush' and while it's a unique design, it was over costly with the many problems it was facing. Guess a water-tube boiler isn't a good idea to put in a steam engine. I have read in one picture note in the Flying Scotsman book by Andrew Roden that Gresley hoped it would supersede Flying Scotsman's speed record, but since its failure in performance, it prompted him to base the former's design to create the A4 Pacifics.

One thing that is not often considered with the rebuilt hush hush was that although yes the cab was larger than on an A4, that was actually quite disliked by crews! Especially firemen. That is because, on an A4, the cab was just the right length that the fireman could place himself in a spot where he could both reach the coal and yet be close enough to the fire door to shovel it in. But because of the longer cab on the rebuild hush hush, they could no longer do that. And had to step back and forth between shoveling up the coal from the tender and swinging into the fire.

I love how your videos get straight into the point. Other youtubers would make an hour-long documentary about this train, but you managed to fit it all into a short but sweet 3 minutes and 20 seconds. Very nice, keep up the good work!

Hush Hush is probably my favourite of these odd experimental locomotives. It’s got a very nice and unusual appearance and had a lot of unique features. Just a shame it did take off properly. It’s nice that there’s surviving archive footage of Hush Hush and that its tender survives on 60009.

“Duck call me a Galloping Sausage!”😡 - Said Gordon

HONEY THE RIGHT TRACKS UPLOADED AGAIN

Hush Hush’s original water tube boiler ended up being a stationary boiler at Faverdale Coach Works, Darlington.

You might also have mentioned that the machinery was not conventional. The engine as built was a 4-cylinder compound, making it far more complicated than just a different type of boiler, and requiring a different driving technique. It was a case of too many new eggs in one basket. The rebuilding not only changed the boiler and the external appearance, it was converted to a conventional 3-cylinder layout as per Gresley's Pacifics.

A galloping sausage!

Awesome video tons of Trackmasters

A great pity it wasn't TOOS before the A4 modification, and preserved as a sole example of a very successful, genius engineer.

This video makes me wish their was a Hush Hush in preservation

Great video had a great time watching thanks for your time and effort kn making this video thanks again

The editing is spot on, fantastic video!

1:04 This LNER Gresley W1 Express Steam Locomotive No.10000 Looks Amazing. Happy New Year Mate. X

Another phenomenal video tons 🙌

Great video! Very well made. God bless you.

It wasn't a train, it was an engine/locomotive. But apart from that, great. 😊 Subbed.

Tell us more about the accident! Looks really interesting

YESSS!!! Another video ❤❤❤❤

Quite informative and well researched! (new subscriber, Virginia)

How does gresley go from designing locomotives like mallard and flying Scotsman to something like this?

Happy Birthday to my favourite youtuber! 🎉

Nice facts thanks tons 🎉

His name should have been Galloping Sausage.

Great video ! Loving your editing but I think it could be a bit slowed down (especially at the end where we have the channel overlay while you are still speaking, its a bit disturbing) Awesome channel nevertheless (I hope you'll make longer videos on these subjects in the future, those are really interesting)

Nice work. Although it was actually a 4-6-2-2 not a 4-6-4. The reason being that the trailing wheels were sprung independently from each other rather then sharing a bogie like the guiding wheels.

I've often wondered what would happen if the 'Hush-Hush' locomotive was given another chance at an upgrade that with the most improvements. And come to think of it, if it *could* be done, would it have made it into a W1X or a W2? I'll have to consult this with engineering experts, same for other locomotives.

Not an enterprising engine gresley was expecting

If it had had an oil burner, it might have worked. Water tube boilers lack capacity; they're like modern domestic gas boiler systems which generally have no hot tank, hot water delivered "just in time". I think it caught firemen out, as much as anything.

It depends what you mean by “Failed”. There have long been trials as development proceeds, sometimes with some publicity, sometimes not. Sometimes they acquire a bad press, but even then they will have led to results that could be interpreted appropriately as the market developed. This pattern of thought is applicable to all forms of traction as they develop over the years.

Ha! Never knew it was a marine high-pressure boiler hack!

I wonder why Gresley didn’t simply make either a proper 4-6-4 based on a A3 or A4. He should have kept the cab the same size but used a larger firebox. I mean, the A1 was inspired by the Pennsylvania Railroad K4s Pacific, so maybe he could have made an upgraded version based on a New York Central Hudson. I know that the 2-8-2s had problems derailing due to their long wheelbases, so a 4-8-2 probably would’ve had similar issues, but a conventional 4-6-4 could have been successful. Hudsons have more power at speed than a Pacific, so it could’ve been the perfect LNER passenger engine.

That Hush Hush Locomotive is a Chonker of the Railway

My favorite LNER Locomotive, besides the Decapod

An interesting and informative video about a locomotive I knew very little about and wanted to know more ever since I saw something about it in a model railway magazine...but by crikey, that was a quick commentary! If you could slow the narration down just a smidge it would make your uploads a lot more enjoyable!

Hush hush is Britain’s PRR T1

It was a magnificent looking loco for it's time.

Well , time to write a fanfic where Aeg Thomas is an experimental engine

Wow.

From what I heard, the W1 prototype worked fine, just wasn't bringing enough performance to justify the costly modifications. (Steamed poorly as per what was expected of it but apparently still worked as fine as the A1 Pacifics)

Prefer more stats. HP? Tractive effort? Comparison to standard models? Thx.

Someone shloud build a replica of this engine! (even though it will use a regular working boiler, i want it to look like as it did in 1929)

Technically I wouldn't call it a failure I would just call it not meeting the Expectations that were set. it did work so in a sense the experiment was successful but it just didn't produce the results they were hoping for. a successful failure you could say.

Great content mate! Just need to slow the pace down a bit. That's just my opinion. But great work.

I realise the boiler didn’t meet performance expectations but was it simpler (or trickier) to manufacture than a fire tube boiler?

If the experiment yielded information it was a success. The continuous modifications indicate the experimental nature of the engine.

Galloping Sausage!!

Well, it’s all rather “Hush Hush”

This might sound dumb to ask, why did this engine got a steaming issues or lacking in power? I mean, that marine boiler can propelled the much larger ships through ocean just fine so how come it didn’t work? Shouldn’t more PSI means more power? I don’t know much about how steam boiler works so I’m kinda wondering. I wish this engine was included into RWS. It can be made into character with similar character arc to Henry.

Theres a game on roblox called Blue Train with freinds they added this as a side mission Ive done it and tried to drive it it keeps derailing 👁👄👁

After so long!

The shape reminds me of Spencer from Thomas the tank engine

Marine boilers don't work for locomotives

Galloping Sausage

Galoping sausage

brainwave

Your tons of trackmasters, arent you?

I see at 1:15 that the route from London to Edinburgh is a direct straight line. The rest of this "presentation" is similarly dubious in content. It feels as if the purpose [with overly rapid narration] is to ridicule Sir Nigel Gresley and the whole of the Doncaster engineering work's staff, or am I wrong?

Very interesting and informative video but please slow down a bit.

10000 was a 4-6-2-2, not a 4-6-4.

I have a Hardback DORLING KINDERSLEY DK EYEWITNESS GUIDES Book of TRAIN. Discover the story of railways - from the days of steam to the high - speed, sophisticated trains of today. In association with THE NATIONAL RAILWAY MUSEUM.

It’s not a train, it’s a Locomotive. A locomotive pulls and a train is pulled. This is not nit picking, it’s simply using the correct noun.

Had to switch this off. Pictures cut short, gabble gabble gabble. Fascinating subject ruined.

What a dreadful production covering a most interesting locomotive. Why you may ask do I consider this to be a dreadful production... Well it was covered far too fast, most of the pictures only appeared for a split second, so quick that it was impossible to see them clearly. Also the voiceover was a constant list of facts making it impossible to take them in properly. The video was only 3 minutes 20 seconds long whereas if it had been more professionally produced it could easily have been twice as long. Having said this I do appreciate the time taken to do the research for a production like this, spoilt in my opinion for the reasons I've already mentioned.

It's a locomotive, not a train, as it says in the title!! Ever heard of Thomas the Tank Train? Thought not!

Are you paid by the word? The more words you can cram into a minute, the more you make? Adios in less than two minutes. Bye!

Very little actual analysis just pictures and effects.

You sound indian, are you?

As well as perpetuating false information, you have missed out significant pieces of the story of 10000. The loco was designed to be equivalent of the A1 and the object of the high pressure boiler was to exploit compound expansion (steam expanded twice) to give more efficient working. The engine was intended as a test bed so was closely looked after by the works who built it which is where it lived and why it is recorded as being there for so long. It had a fundamental problem with a sub system which took a long time to diagnose. This system was for reducing steam pressure for use on ancillaries. This failed to work properly leading to problems with the injectors which put water in the boiler. To safely operate, the crews had to run at reduced power and pressure which effected performance. Steaming was further compromised due to air leaking into the casing reducing the ability to pull air thru the fire for combustion, so as a work around, expansion in the cylinders was reduced so more draft could be created via the exhaust to pull more gas and air thru the boiler -> higher fuel consumption/ poor steaming. While this was getting identified and fixed, the performance targets moved to chase the A3 (higher power). It eventually met and surpassed this but then came the A4 and everything changed and time was called on it. There is so much more to this than I and certainly you have said. If interested, go read William Browns book on hush hush, it is very illuminating. When you have done that, remake your video as it is currently incomplete at best.

Why condense sentences together so that it sounds as if you don't take a breath? This american style presentation spoils an otherwise excellent film!
