Suggestion: the Milwaukee Road “Class A” streamliners, and/or the MILW F7. Not nearly as many of these built as the A4, unfortunately, but they did break records at the time, and they’re also just COOL looking.

[@davefrompa5334]

@@wesw9586 Possibly, but unofficially. The Milwaukee Road never did an all-out speed test with a dynamometer car. The Atlantics and Hudson/Baltics that pulled the Hiawatha were said to have reached or exceeded their two mile a minute design speed during schedule setting runs, but most American steam roads in the thirties weren't that concerned about top speed bragging rights, just what was practical in regular service. The Hiawathas WERE the fasted REGULAR SCHEDULED steam trains anywhere though. The second fastest steam locomotive after the Mallard, at least officially, was the German 05 class, It reached just under 125mph in 1936, The train included a dynamometer car.

[@colinwhite5355]

As a little lad in the early 60’s, I remember standing, at ground level, right next to the driving wheels of an A4, in Hartlepool station, just off the end of the platform. So, so quiet until she started her roll, lost traction and, accompanied by massive and dramatic wheel spin, finally bit the rails and set off amidst clouds of steam and a crescendo of mechanical bliss. Never to be forgotten.

[@jaycooper2812]

My father was an engineer for the Milwaukee Railroad for about 20 years. I rode with him on "Little Joe" EF-4 as a child. The first engine my father operated was the famous "Hiawatha" an American Locomotive Company 4-4-2 "Atlantic" steam locomotive which consistently traveled at over 100 miles per hour.

[@johnscarsandstuff]

Calling the Deltic "soulless" is practically fighting talk in these parts ;) Great video nonetheless, although I think the most important part of the A4's streamlining was the work done on the internal gas flow. I also think it is one of those nice historical coincidences that Gresley and Ettore Bugatti were friends and Bugatti's work influenced the shape of the A4. While Bugatti's great automotive Rival, W.O. Bentley served his apprenticeship at the Great Eastern Railway and would have been there (if I remember correctly) while Gresley was Chief Mechanical Engineer.

The A4 is such a source of national pride that, even to this very day, 92% of all reams of printer paper sold in Britain are named after it.

[@johnbrooks6243]

This is a joke or actually real reason

[@bigal3055]

@johnbrooks6243 It's 100% true. You're free to look it up for yourself, but why do you think that the shop where you traditionally bought the paper from was called a Stationery shop? Just coincidence?? They were originally called Shed shops, after the engine sheds which housed the locos when they weren't in use, but it caused a bit of confusion with garden centres and the British laws at the time, which demanded that all privately owned back gardens had a garden shed to allow for potting, fettling and tool storage. You have to understand, of course, that it was a very different societal attitude back then. The British Empire, though in decline at that point, was still very much a global power with a global influence. An empire that had been built on the steam powered British invention of the Industrial Revolution and the global reach of the also British invented automatic printing press. It was Britain too who first came up with the notion of selling bread and milk through newsagents, popularising a global trend of reading the morning newspaper with a cup of tea and some toast and jam. Marmalade was popular too, but some people weren't keen on the bits in it. I digress. Of course, the milk and bread would come in locally to the newsagents from the various farms and bakeries in the surrounding area and you'd have all day to faff around getting the evening edition of the papers out. But to get the morning edition of the paper from the printing presses of Fleet Street in London and up to the newsagents of Glasgow no later than 0530 in the morning, when the milkmen and bread vans of Great Britain were already criss-crossing the towns and villages of the country making their deliveries and the paperboys were warming their pushbikes up in preperation for the morning rounds, it took something a bit special. Something fast. Something with the power, range and reliability of Nigel Gresley's A4. With the A4 on the job, it was, for first time in mankind's history, possible to read the very same newspaper article at one end of the country with your breakfast, as it were at the other end of the country. You simply can not understate just how much of a revolution in media coverage and broadcasting things and stuff to the masses this was. It was the high speed, fibre optic broadband network of its day! Some of the very first stories in the papers that had been delivered hot off the London presses to the top of the Scottish Highlands were ironically about the hysteria and national jubilation of achieving such a thing leading to some housewives to pass out in disbelief when they came downstairs to find that morning paper was already sat there on the floor, though I personally think that those stories were just a kind of early form of some proto-clickbait thing for newspapers. Still, that doesn't detract from the fact that the A4 locos were and still are something we Brits hold in as high regard and pride as things like Concorde, the Spitfire, Harrier jump jets, the Mini and Vimto. The A4 is just that much of a national icon and treasure to us and it was only right that its name is still honoured on the most used paper of the kingdom. Paper which, just like the internet we know today, was used to bring honest, reliable news and information that everybody could trust to the masses. As long as there is a need to print paper, the history and impact that the A4 had on delivering the papers from the printing presses will be remembered with pride here every time we reload the copier. Now, in all the workplaces and schools the length and bredth, how many countless times a day do you think that the national photocopier fleets are reloaded? No sir, honouring that sleek, streamlined, beautiful, grand old powerhouse of our country's proud history and paying tribute to the effect it had on the press media by adorning our most commonly used size of printer paper sleeves with the A4's name is no joke!

[@Zgurkogel]

@@bigal3055 Amen to that! Love a good bit of British trivia. 😍

[@bigal3055]

​@Zgurkogel It's a rich and layered history, full of fascinating trivia. For example, did you know that before the A4 came along, it was impossible for fish and chip shops any further north than Wigan to open for lunch? The newspapers would arrive so late that far north that people would still be reading them well into early afternoon, leaving the chippies with nothing to wrap lunch orders up in until tea time. Once the A4 saw to it that the papers would be there in the early morning though and that everyone had read them by the time the morning tea break was over, they could open for lunch too and people could now enjoy some fish and chips twice a day. The effect on the fish and chip industry was profound and the explosion in demand for newspapers was so dramatic that entire news corporations, which still operate to this very day, were founded on the printing of papers that weren't for readership, but would instead be sent by the millions straight to the nation's chippies every single day just to satisfy the insatiable appetite the chippy boom created for a cheap, absorbant wrapping material with good thermal insulation qualities.

The A4 paper size is based on a German standard (DIN 476) published in 1922.

One small correction. Gresley did not become CME of the Lancashire and Yorkshire Railway in 1911, it was the Great Northern Railway and the L&YR was amalgamated into the London, Midland, and Scottish Railway upon the Grouping Act in 1923 and not the London and North Eastern Railway. Also the "K4" seen at 7:55 is the Pennsylvania Railroad's K4 class 4-6-2 Pacifics which is a very different beast to the LNER's K4 class 2-6-0 moguls.

I'd be interested in seeing an episode on the Deltics, or even an episode covering the whole push to Diesel traction that BR took. Its an interesting story that saw many designs and ideas come into play across the rail network.

[@Tom-Lahaye]

The map shown of the line where the A4 apparently started service shown in the video is actually the line where the concurrent LMS Coronation did service. It is the West Coast Main Line which belonged to the LMS in the Grouping years. The LNER operated the East Coast Main Line from London to Edinburgh via Peterborough, Doncaster, York and Newcastle and that's where the A4s operated at their introduction. Also, the main reason for Gresley to build the A4 was the race to the North in the first place, a race for having the fastest service between London and Scotland that took up pace after an agreement on limiting train speeds ended in 1932. The Grouping also played a role in this as from then on the LNER owned the full ECML to Edinburgh and the LMS the WCML to Glasgow respectively. The fastest train of the LNER, the Flying Scotsman, had no intermediate stops on its 393 mile journey. Before the grouping trains on these routes would pass over the territory of 2 or more companies. The competition with the Germans was not so much with the SVT 877 but with their attempt at building the fastest steam locomotive, the Baureihe 05, a large Hudson type locomotive of which due to the outbreak of war only 3 would be built, 05 002 reached 124,5 mph after which Mallard did her final record setting high speed run at 126 mph. And no, the Deltic isn't a soulless machine but a unique locomotive with the most complex diesel engines ever in a locomotive, once the most powerful single unit diesel locomotive and with a great share of followers of the also 6 preserved series deliveries, and the prototype DP1 is also preserved.

[@darkhymn]

I love train people.

[@teraris]

The whole thing is a mess. Apparently the Lancashire and Yorkshire became a part of the LNER too and Gresley never moved to the Great Northern Railway, and there, designed the precursor of the A1 Pacifics, of which the Flying Scotsman is a survivor, namely 'The Great Northern'.

Three cylinders were a nightmare. The Union Pacific 9000 class famously had them and they were not popular with UP mechanics. Imagine what access to a third set of running gear was like on those things. Two smoke stacks were not always necessary. N&W used a wafer in a few of its locomotives that enabled a seal to be maintained around expelled steam through a single large stack to create draft. The LNER may have been quick, but the 4-8-4 N&W J class was not much slower and had a lot more power. That was much about a huge lagged fire box sitting over a four wheeled truck. 70" drivers, roller bearings, and connecting rods going to the second drivers rather than the third also helped. Some of the 4-6-2 locomotives used in the states were no slouches either when it came to speed. If all conditions were equal, the Milwaukee Road's Hiawatha class which had been clocked at over 112 mph may have kept up with the LNER locomotive.

[@arikfick5122]

Fun fact-the Mallard is the fastest *recorded* steam locomotive.

The PRR T1 could still blow the record out of the water. There is a nonprofit organization working on building a new one built to the same specifications as the original ones. Some things just aren't cost effective or practical to do today, such as casting the frame. It would cost millions to have patterns and molds made, not to mention there are very few facilities left capable of pouring that much metal all at once. So, they've opted to weld plate steel together. Which is stronger and less likely to have defects than cast-iron. There were stories of them hitting 140 mph, but it was never official. With modern lubricant technology, metallurgy, and welded track, it's designed 140+ should be possible.

1. The 'Insane' speed of 126 was only 1mph faster than a german loco had achieved - on the level - and it seized up a bearing in the process. 2. He didn't 'eventually' furthur refine the A1s to A3s. He put it in hand after Pendennis Castle outperformed them them in the locomotive exchange. At that point he followed Churchward/Collett (GWR) lead on longer valve travel and higher boiler presssure. 3. The Gresley conjugated valve gear was a clever idea but a bit tempramental and was never used by his successors. The A4s were built to haul 9 car trains on a mainly level racetrack and they fullfilled that task superbly but also coped with greater loads post war. Simmilarly the Princess Coronation may initially have got into speed competition but they were built to haul 12+ cars over Shap and Beattock and they did that admirably. So whenwe're talking loco designers lets hear it occaisionally for the likes of Churchward and Stannier.

And immortalised in the track "East Coast Racer" by the band Big Big Train.Well worth a listen. Available on all good streaming platforms!

[@kineuhansen8629]

i love that mallard is still arround today a4 are truly amazing engines as we called them i even have a model from hornby of her even have some flying scotsman first official to hit 100 mph

[@makschorney2514]

Not a train guy, but this series of locomotives was perfection. If I had the money, I would have a train diorama depicting the record run!❤

[@79Batty]

I grew up in a house opposite the shed 60009 Union of South Africa was kept through the 80’s. Interesting fact she’s the only locomotive to have crossed both the Forth rail and Forth Road bridges. This was bettered when she was driven north again to Fife in retirement over the new Queensferry Crossing so having crossed all three bridges between Fife and Edinburgh.

[@tidepoolclipper8657]

One of my favorite locomotives in terms of looks. Also a rather good locomotive name.

[@adamczechowski614]

Back to Classic Megaprojects. :) 2:42. Wait wait wait .... WHAT STATUE??

[@SitInTheShayd]

I last asked in the Big Boy episode but, I would love to see either a mega or a side project on the Shay Geared Steam Locomotives

[@monsvillerailways5736]

Nice one Simon. The Princess Coronation Class still gave the A4 Mallard a run for her money. War years took a tole on both. Great video. 👍

[@markusbaur2128]

and the German BR 05

[@MrDeskart]

The Mallard such a beautiful machine

[@FM60260]

7:54 That is the wrong K4. The example pictured is I believe the Pennsylvania Railroad K4, an example of the LNER K4 is 61994 "The Great Marquess"

[@oculusangelicus8978]

Steam locomotives are so much cooler than their diesel electrics replacements, there really is no comparison between the two. My father worked on steam trains in the CPR (Canadian Pacific Railway) here in Canada. when he was a young man and I have had the pleasure of riding Steam locomotives a number of times and they are a nice way to spend an afternoon. There are many closed steam railways in Canada some in theme parks and others on retired lines between certain towns, but they always gather lots of customers willing to ride them for a fee, and there is a small steam locomotive in a small town in Alberta that provides a reenactment of an old west train robbery and the customers get to live the trill of being robbed by train robbers and the watch as the local sheriff Guns them down as they try to use their guns to escape. after that the train continues on to the destination town where a meal is supplied as part of the trip and then a leisurely return to the originating town is made. Runs every year. there is also a couple of running steam locomotives in the Theme park in Calgary, known as Heritage park, that has old houses, hotels, barns and other buildings saved from destruction and built as early as the early 1800s as well as a period amusement park and even a paddle wheeler boat that can be ridden on the Glenmore reservoir, A reservoir fed by a local river called the Elbow River, that comes all the way from the Rocky Mountains about 30 minutes West of the city.

[@jameswingrove7421]

It was the Mallard that got me interested in the railway, and is partly to thank for my own subsequent driving career. The Diesels just don’t have the same allure as the steam engines of yesteryear.

[@totoche8383]

We have one in a museum in Québec, Canada... its call dominion of canada. Its possible to see the inside of the locomotive. It's very impressive

[@pascaldechamps5006]

Two thoughts 1 in Old times, turntables had a pitch control allowing for plus/minus speed 5%, might be of some use, 2 look at SNCB type 12 (1939)

[@Neo-Midgar]

Though it wasn't recorded in the same manner as the Mallard, the PRR S1 regularly went over 130, and even reportedly topped 150 on a run

[@aaront4494]

Such beautifully designed machines.

[@R0bobb1e]

There really was something special about the steam era. Not saying I want to live then, but a little of the romance being brought forward certainly wouldn't hurt.

[@ianbarkham5080]

Nice article on these in the current issue of "the Chap"

[@audigex]

12:11 That's the West Coast Main Line (Domain of the LMS), not the East Coast Main Line (where the LNER and LNER A4 operated)

[@georgecrook92]

Growing up in York got to see this bad boy at the NRM all the time

[@Farquad76.547]

Went to see it yesterday from Michigan usa to Chester to York!

[@Jfrye117]

I don't mean to nab at 7:55's K4 picture, however that is a picture of the Baldwin/Altoona built American K4 of the Pennsylvania RR. But yes, there IS an English-built K4 that Sir Nigel Gresley designed :)

[@Radioactive4001]

This title is a bit misleading, the mallard was the fastest confirmed steam train. But there have been many others that have been reported reaching higher speeds.

[@Hard-Boiled-Bollock]

I find it amusing that other members of the class were called Golden Eagle, Falcon, Osprey, Sparrow Hawk.. but the one that got the speed record was called Mallard

[@josephschultz3301]

Train Kid from the Game Grumps would love this episode, Simon :D

[@douglasengle2704]

The A4 is magnificent steam passenger locomotive! In the UK without its own strategic petroleum it made sense to keep the railroads fueled by coal. The USA Pennsylvania railroad's 6,500 horsepower T1 duplex steam passenger locomotives were made for 140 mph pulling 16 car long trains. en.wikipedia.org/wiki/Pennsylvania_Railroad_class_T1. Track speed didn't allow for that officially, but the valve gear was failing when it should have been good for 140 mph. The valve company secretly sent agents on the trains heading into Chicago and timed mile posts at over 130 mph. With wheel slip that was pushing the locomotive valve gear into high wear. Instead of criticizing the locomotive driver the valve company started making the valve gear out of higher alloy metals.

[@ThePTBRULES]

You mean ot was😊 designed fkr 120mph, but T1s were clocked going 140.

[@cr10001]

I'm afraid I don't believe that. Given that high speed on railways was a big thing in pre-war days, and the PRR had its big engines specially styled to look like streamliners, and they were in intense competition with the NYC - if they were capable of breaking the world railway speed record (and even more so if they actually had done, repeatedly!) howcome the PRR publicity department didn't even bother to mention it? Seriously. Authenticated records or it didn't happen.

[@kristoffermangila]

One reason: the speed limits imposed by the Interstate Commerce Commission, that much-maligned offshoot of the Progressive Era. In the 1920s, the speeds attained by the crack express trains of the various American railroads like the 20th Century Limited of the NYC, the Broadway Limited of the Pennsy, and the 400s of the C&NW, to cite some examples, are in the 100 mph and beyond range, and that raises concerns among people, especially because the safety equipment onboard these trains are still not perfect. And so the ICC imposed a speed limit of 100 mph, with stiff penalties for the transgressors. I forgot the penalty is for the offending railroad, but for the guilty engineer (correct me if I'm wrong), IIRC, it's in the region of around $5k, quite a sum in those days.

[@DesertFox32k]

TRAINS! Simon, you play to kids heart in us all with the train videos

[@bnicklow359]

The Mallard is most definitely an impressive piece of machinery and unquestionably the fastest official steam locomotive. I would love to see a video of the Norfolk and Western's J class. They were similarly the US's rendition of throwing all the best advancements and efficiencies in attempt to save the best for last and were some of the last steam locomotives produced. While not questioning the speed and superiority of the Mallard's speed record, there are plenty of stories about the J class hitting that mark during regular service in the engineer's attempt to make up time. An official speed record attempt was never tried as far as I know. Another note, there was one other Locomotive that was as or more technologically advanced as the N&W J which was the PRR T1 class. These were never regarded as successful as the J though because of a combination of peculiar operating characteristics and a lack of training which held their performance back. There is a group call the T1 trust that is building from scratch a brand new T1 which is about 75% complete if I'm not mistaken.

[@markstott6689]

Every visit to York involves giving the Mallard a kiss since 1978. 😊❤😊 Calling Sir Nigel "Greeseley" Instead of "Gresley" is a travesty. 😮❤😮

[@CrazyBear65]

A lot of things _were_ better in the past, Simon. Prices, for one. The Mallard is an A4. It's so famous that we even know about it over here in America.

[@warwickholden6332]

When the deltics took over from the A4 pacifics on the LNER express 'The Flying Scotsman', they knocked 1 hour off the time from London to Edinburgh. Not because they were faster, but because of two things. They had much better acceleration. This was the steam loco's achilles heel - slow acceleration. And the second was that the deltics were designed to 'cruise' at 100mph easily. So they spent more time at higher speeds than the steam locos they replaced. Also, each steam locomotive was uniique. This followed from their being hand built. Mallard had a known problem with ono of its main wheel bearings, and the maintencne crews put an aniseed "bomb" just near this bearing. It was aniseed liquid in a sausage skin. If the main bearing had too much wear it broke the "bomb" and the crew on the footplate knew there was a problem. This happenned on the record breaking run, and the Mallard had to be taken out of service when it reached Peterborough.

[@ZodiousE]

It's amazing how the betterment of aerodynamics increased the top speed of steam locomotives by very little considering that the UP 844 achieved 120mph and has the equivalent aerodynamics of a barn. The difference in tractive power is only 3.81 lbf/1lbs favoring the 844. The 844 was/is stronger but also heavier.

[@leightonmoreland]

The PRR T1 class is alleged to have been able to cruise at 120 and peaked at speeds of 140. All of the original ones were scrapped but one is being built new, who knows how much longer the A4's will have their speed record!

[@rollerdragon]

ok... after literal YEARS watching ALL of your multitude of channels, i have realized this thing:... you, sir.. have given me the BBC of the seventies experience!! [yes, i mean this in a good way... SUCH a broad range of subjects you remember exactly ZIP about, have given me a head full of things i did NOT know... funny, that... Cheers!

[@katashworth41]

The Mallard will forever remind me of my dad as he had a pint pug with it on. I know where I get my healthy habits from, a man who would drink pints of coffee.

[@Enjoymentboy]

The fastest steam locomotive ever?!?!? NONSENSE!!!! I saw a documentary about a scientist in the old west who got a steam engine up to over 90mhp with a few coloured logs. it would have kept accelerating but some idiot forgot to lay enough track for it so they decided to make it into a plane. It even flew over a good portion of a ravine. It came out in 1990 and I'm pretty sure it was part of a series that began with clocks.

[@jetsons101]

A "Vintage Steam" video from Megaprojects..... It's going to be a great day.......
