Just a friendly note that there is actually also an 8th P2 under construction too. - The 7th P2 project, 2007 Prince of Wales, costing £6M was launched in 2013 and has progressed as far as building the frames, tender, cladding, wheelsets and cylinder block, with the boiler and electronics on order. The build will recreate the original streamlining and feature rotary cam valve gear, but with many updates under the skin to try and improve the original design. This P2 is being built in Darlington. - The 8th P2 Project, 2001 Cock o' the North, costing £5.5M+ and launched before the other project, has not progressed so far, having so far built the frames and designed many parts in CAD. They aim to build a faithful replica of 2001 in it's 1938 rebuilt form, with streamlining and Walchaerts valve gear. This P2 is being built in Doncaster. Arguably having two companies rebuilding the same class of locomotive (while not publicly collaborating or acknowledging each other) is not particularly helpful, and the fact that you got confused between them is completely understandable. Anyway, still a great video ;)

Edward Thomason rebuilt a lot of Gresley engines due to wartime shortages and wanting to make the engines more standardised and have longer maintenance intervals and be easier to work on. A lot of people don’t like Thompson engines but the truth is he was given the near impossible task of making extremely complicated and unique engines less complicated and standardised on a shoestring budget. The Thompson B1s which he designed from scratch where great engines comparable to the black 5

Few extra notes The P2s not only resulted in the A4s but also the Peppercorn A1s (as the P2s lead to the A2/2 which went onto the A2/3 then the Peppercorn A2 and A1) The main reason for rebuilding the P2s seems to have been their low availability figures due to their crank axles failures (though this seems to have been an unknown flaw as to why it kept going wrong). Thane of Fife was the first rebuilt but it wasn't until a year later the other 5 were also, as they did test her to ensure that the A2/2s would perform better than the P2s, which arguably they were improvements if only incremental ones

[@williamrobinson7097]

The reason for the crank axle failure was due to it being the same design as the gresely A1 and A3 for interchangeability which was fine for them but as for the P2 they lack beef to withstand its power

How about ... Isambard Kingdom Brunel .. That takes some beating. Little schoolboy me saw that locomotive fresh out of Swindon Railway UK works back in the 1950s looking like a brand new build. As it approached, I was expecting to see a Castle nameplate but it had been renamed. That Castle Class were impressive with four cylinders. I saw one at full chat through Swindon Railway Station heading "The Bristolian" outbound from London to Bristol. Until then, I had no idea a steam train with so many long coaches could travel so fast as it flashed through the station non-stop express style. The eight power pulse exhausts from the four cylinders merging into one glorious continuous sound at that speed. Had no idea what that name was about back then.

[@kimpatz2189]

The rare Mikado P2 of the UK. Other rail operators outside of UK used them as heavy freight locomotives. The UK however put them on passenger express. The power and adhesion was certainly needed but they still didn't harness the full potential of the Mikado type by not switching to a Janney type, or other derivatives stronger than a chain link coupling, for coupling cars/trucks together. This problem also spelled the end for the garatts as their power could decouple them to their trains. The x-8-x wheel arrangements is in between the x-6-x for speed and the x-10-x for heavy freight. The x-8-x has large enough driving wheels to go fast without compensating adhesion. It can carry a larger boiler owing to its longer frame. It can do both express pax and moderate freight without bogging down unlike the speed demons of the x-6-x. Some crazy contraptions based on the x-8-x platform is the widely debated T1. The 8 wheel formula also made the Big Boys balance of adhesion and speed. And the last 8 wheel platform to truly challenge electric locomotive was from the SNCF 4-8-4.

[@joshslater2426]

I can’t wait to see the new build P2s when both Prince of Wales and Cock o’ the North are completed. I can just imagine how intimidating they’ll look when you stand next to them on a platform, something no one has experienced for a long time.

The P2 makes me wish Britain's railways had more mikado type locomotives.

But I'm guessing 2-8-0's and 4-6-0's did the trick for y'all just fine. Can't argue with the Black 5 or 8F after all.

[@mattevans4377]

The only bigger loco that really worked for the UK was the 9F, which was better than the menagerie of other large locos built for niche purposes, and could also be used as a mixed traffic loco (although not advised due to the small driving wheels, even if it could do 100mph with them). It was just the right engine, at the right time.

[@fuzzyhead878]

@@mattevans4377 That too. The 9F’s are arguably the prettiest 2-10-0’s ever produced.

[@jamesedwards7241]

Railways in the Uk were into building their own motive power with individual regional companies having vastly differing views on what was required and unlike the US with seriously dedicated locomotive builders offering off the shelf products modified to suit. Gresley appears with the P2's to have taken a look into the abyss of horses for courses with a little twist of devilry added for spice. What was needed in Scotland was a locomotive with light axle weight, high tractive effort and good acceleration, top speed not being something that really figured in the equation with stations being in such close proximity on a route more up or down than flat, the tech already existed so what led him off on such a tangent no one will ever really know possibly the low predicted class numbers lent itself to some petty flights of fancy only he would know. Was the P2 a failure? in essence yes, let down by a lack of finality in design, could they have been a great locomotive. doubtful, they would not have fitted well into freight operations-basically being too big for the day and the only other route they might have served well on belonged to the midland railway that time frame was filled by the 9f years later which employed everything the P2 lacked, All is not lost with the build of a new old design but even there they have taken a box of what was, shook at severely and whatever fell out is what they are building again with added spice, will it work out of the box, doubtful it will but they will fix it eventually because its the only one they have to play with.

[@polbecca]

@@jamesedwards7241 In fairness, David Elliot has corrected in his design of P2 2007 the earlier problems with the pony truck that led to poor handling and crank axle faults, and the Lentz valvegear that was prone to wear will use better materials. Still a way to go but it's come on leaps and bounds since my visit, shortly after the frames were erected.

[@garryferrington811]

Economies of scale: nations built the engines which were most needed and worked best for them. The UK had the most comprehensive rail network on earth, one which reached every city, town, village, and hamlet. Gigantic 2-10-2's or similar engines would have been economic suicide. The Soviet Union also had big engines because they needed them.

[@terryashton3541]

I used to do my trainspotting back in the 1950s and never seen any of these P2s but do remember very well some of the rebuilt A2s and from my point of view they were one of the most beautiful engines running around at that time and powerful too, I can remember one vivid memory of seeing 60535 Hornets Beauty in ex works condition coming out of Doncaster works in 1959 and for me personally I thought Thompson was way ahead of his time with regards his designs especially the P2s, and with regards to the A2s tractive effort they were as powerful as the Princes Coronation class and some even more powerful and they were only a 3cyl locomotive, thankfully there is one nearly completed at the moment and that will be some sight to see.

[@hoskinb1]

Thompson took over as CME at a point when the LNER was in dire straits due to WW2, a lack of funds and a fleet of locomotives that had a something of a mixed reputation. The P2s were costly to run and maintain, and caused problems on the track on the Edinburgh to Aberdeen line. They also spent a lot of time in works at a time when the LNER needed as much of its motive power to be available for the war effort as possible. They were a small, non standard class so Thompson tried to make them more reliable and easier to maintain with a greater route availability. The rebuilds may not have fully succeeded but they did pave the way for the rest of the Thompson and Peppercorn Pacific designs that would serve for the next 20 years. As for the rebuilding of Great Northern, Thompson would have had no interest or input as to which individual Gresley A1 would have been chosen. Great Northern happened to be about to enter works at the time the rebuild request was agreed. The LNER did not have the resources to build a potentially one off brand new prototype from scratch at that time so modifying a suitable existing loco would have been the only option. Thompson gets a raw deal at times but he took charge at a time when the LNER had a number of significant challenges and restrictions, he did an incredible job under very challenging circumstances.

[@kevwebb2637]

Plus the fact that most of the LNER locomotives are Gresley design, Thompson don't have much of a choice on that one. History In The Dark did a video topic on him.

One thing that interests me is the fact that the 2-8-2, or Mikado, wheel arrangement, is normally associated with freight locomotives.

[@cwt5654]

Wheel slippage is always an issue with locomotives having an non-driven trailing axle (i.e. 4-6-2) as weight balance transfers rearward under load. Having an additional driven axle helps compensate for this propensity.

[@EllieMaes-Grandad]

Many years earlier, Gresley built a couple of P1s. Superb loco's, they were 'too good' and could haul more loads than the infrastructure could cope with.

[@jenniferwilliams2077]

The music is from Paper Mario The Thousand Year Door Chapter 6 when it was nighttime on the Excess Express.

[@rannorgana]

One of the theories why Edward Thompson rebuilt the P2's was of possible anger towards Sir Nigel Gresley, who was his predecessor. The possible reason for this was that he (Edward Thompson) felt that Gresley had pushed out or was chosen over Sir Vincent Raven (At the Grouping of the railways in 1923, the post of chief mechanical engineer for the London and North Eastern Railway was given to Nigel Gresley of the Great Northern Railway, with Raven becoming a technical adviser. He resigned in 1924 and was appointed to the Royal Commission on New South Wales Government Railways, in company with Sir Sam Fay.) Given that Edward Thompson had married Sir Vincent Raven's Daughter (Edward Thompson was Raven's son-in-law (married Guendolen in 1913).) perhaps he felt that his father-in-law should have been chosen? Just a theory.

Currently preserved at the Newport Railway Museum (Melbourne Australia), it was nicknamed Heavy Harry. He had several technical updates for transferring coal into his fire to ensure all parts of the boiler got aliquoted heat. Although not as fast as his smaller contemporaries, he could deliver trains faster than them because he didn’t have issues with inclines. If you want a bit more info or a bit of video, let me know.

Actually, an eighth engine is being built too at Doncaster Works. A wedge nosed 2001 replica.

[@georgeoliver8300]

It’s been like 10 years and they’ve only cut out the frame sheets. That’s never getting finished.

[@classic_britain]

Really I did not know that!

[@mlp-hot-rod5824]

@@georgeoliver8300 Really? Yikes. They might as well have donated the frames to Darlington.

Its a type of valve gear It’s what makes the machines move

[@alanhindmarch4483]

The 7th P2 2007 Prince of Wales, as in the Photo is not being built in Doncaster, but in Darlington, please get your facts right. There is a rebuild of Cock O’ The North being built in Doncaster, but its not the one in the Photograph.

[@waverleyjournalise5757]

Much prefer Cock o' the North and Marischal's squared-off designs to the streamlined four. Something about them combined with those huge wheels and long frames works. The look of the streamlined engines has never grown on me

[@loco42041]

2-8-2 wheel arrangement, not eight wheels.

[@whatdoyouexactlymeanbyhandle]

um aCtHuAlLy, he was saying eight DRIVING wheels; a loco with eight driving wheels is often referred to as an “8-coupled” engine.

They walked so that diesel locomotives can run.

I wished that these locomotives were Thomas characters because it would’ve been an amazing design for a character

[@MattyP62618]

"Nobody is quite sure what sparked Thompson to do this" I mean all you have to do is look at the (dreadful) availability numbers of the P2's & the fact is was considerably cheaper to rebuild than scrap them build a new loco... They also really didn't flawlessly perform the work theg were given... Train of lack of thought more like

[@thatonecaledonian812]

Am I gonna be cancelled for saying I kinda like Thompson designs despite most of them being ugly to most

[@vickielawless]

I actually like his B1 and K1, very neat locos. Have you read Wartime CME by Simon AC Martin, totally debunks the anti Thompson narrative we've been fed all these years..

[@ivanthevaluable2559]

Could they not have named it "Rooster O' The North?" The name is way to inappropriate

[@yeoldeseawitch]

some words meant different things then they do now like "Gay" meant happy and "Fortnight" means 14 days and nights

TFW Europe had to resort to Mikados but they were so embarrassed by ut this very video dare not mention the word Mikado even once And you know what that means MURICA FUCK YEAH COMING AGAIN TO SAVE THE MOTHER FUCKING DAY YEAH AMERICA FUCK YEAH TRAIN OF THOUGHT KNOWS WHAT'S UP YEAH

[@cr10001]

That has to be one of the most stupid and obnoxious trollish comments today. The P2's owed virtually nothing to American practice. If you're going to play that game, I'd point out that American locomotives would have been useless without European Walschaerts or British Stephenson valve gear. But so what? It's a stupid game, nobody has a monopoly on railways.

[@kevwebb2637]

@@cr10001 There were some US Exports to the UK. The 2-8-2 wheel arrangement did started in the US though.

[@andrewj15]

I did hear about the p2 class but never knew that they were experimental locomotives

[@EllieMaes-Grandad]

Not so much 'experimental locomotives' as locomotives subject to experimentation?
