Marc Seguin: The Basics

- Marc Seguin was the French engineer who designed and patented a revolutionary multi-tubular boiler in 1827 (two years before that of the Rocket) and who was the first engineer to think of applying such a boiler to a railway locomotive - over a year before Rocket in Britain. This is the story of Monsieur Seguin and his locomotive.
In my home state of Maine, we started out with a tramway and two locos (which were sadly scrapped) imported from England in 1836. Our oldest surviving locomotive is a four-coupled tender loco called “Lion” built for a logging railway in Machias, a coastal town, a decade later. It’s got quite the interesting story.
Thankyou, that explains a great deal. My compliments upon your French pronunciations.
Thank you! There's a francophone version of the episode available, too.
He's my ancestor; nice to see this!
Thank you so much for these snippets of early railed way history,they're great!!
Thankyou!
If only photography had been invented earlier.? Makes you realise what a massive wealth of information will be available to the historian of the future.
Oh, a lot less information will be available than you think. Anything stored digitally will almost certainly degrade well before the historian of the future can peruse it, and film, of course, can degrade if improperly stored.
Interesting concept of a external firebox I would think it would be harder and not easier. Such a fascinating engine and the man behind it equally as fascinating
Really interresting and well done! I really enjoyed it. Your french pronounciation is impressive. It is off for Seguin though, which should be pronounced as [sœgɛ̃] and not "segun". The closest I can think of in english would be "Seguin", like in "terrain". The end is still a bit off too, but "in" sound in French does not exist in English and this is the best approximation.
Keep up the good work: I am now subscribed!
Thankyou for the clarification. The worst I ever his name pronounced was in England as "Seg-Win".
these videos have been extremely informative. I've gone from knowing almost nothing about early rail, to knowing a fair bit, and having a much better understanding of our railway heritage as a result. Thankyou.
It’s interesting how steam power and railways might have developed in France, given the presence of pioneers such as Cugnot and Seguin, had conditions been more suitable. Perhaps they could have developed the steam railway before us!
Didn't know France got off the ground with railways this early. Good job.
Thank you for another brilliant video. I try to imagine the voluminous amount of in-depth research that goes into the production of just one of the videos. To multiply that amount of work by the number of videos defies comprehension. Clear, concise and entertaining writing style. The whole thing is first rate.
Q: When do we get out diplomas?
I dont know about your diplomas, where's my PhD!? It's pretty much a full time job, alongside my real jobs. A lot of time, effort and love go into these. Glad you enjoy them! and yes I might do a diploma....
excellent
Thank you! Cheers!
Can you cover the steam elephant and / or the Puffing Billy / Wylam Dilly please?
They're in the pipeline. Watch this space/
@@AnthonyDawsonHistory I will watch out for them then.
is the French engineer Marc Seguin remembered in France today because recently a friend mine helped to rediscover a fellow French engineer who's name had been forgotten in England the French engineer in question designed a early type of safety valve which he used as a important part of his pressure cooker
He is, certainly His name is on the Eiffel Tower. He is over-looked in English-speaking histories of the railways as a footnote which is very frustrating. History in Britain can be very insular and we like to believe in Britain we invented the railway and the railway locomotive. And the steam engine too, despite Denis Papin in France coming up with the idea before Thomas Newcomen. And people believe that becuse it's what theyve been taughr whether it's true or not. Same with schools still teaching George Stephenson 'invented' The Rocket for the Rainhill Trials.....But in France there isn't the same love of nostalgia and love of the past as in Britain or America. There are railway enthusiasts, steam railways, but nothing like on the scale in Britain and most of the steam railways are fun as commercial, tourist ventures rather than as a living museum. There isn't this desire to escape into the 'safety' of the past. There's also a bit of a grudge, for the want of a word, at how Seguin in the English language historiography of the railways and the locomotive is overlooked, simply because he was French and lack of foreign langauge skills (books in French are apparently unacessible.....) So yeah Seguin is certainly remembered and commemorated
@@AnthonyDawsonHistory Papin also developed the concept of the steam engine created by Thomas Savery, the true inventor of the modern steam engine. Spain's design of 1707 would have infringed Savery's patents did Newcomen's. The problem with saying Papin invented the pistonstwam engine is that there is little evidence that he got beyond the model stage. It's a it like saying George Cayley, another Yorkshireman, invented the aeroplane when all he did was create a design that matches the layout of most modern aeroplane. Although he was the first to put down the forces on an aircraft's wing.
A missing link in the steam story uncovered.
More peerless research young man! You did overlook Twin Sisters being was Henry Booth's first attempt at a Multi tubular boiler? Looking at the Marc Seguin, she still looks like the very thin tubes will easily clog with carbon deposits, and it looks like there is no real way to clean them. Does the replica have any kind of modifications to access the tubes? Also, Red copper? Am I right in thinking red copper is purer? What are its benefits?
The boiler tubes were 4cm diameter so quite large. The duct on the end of the boiler is removable so the tubes can be cleaned. Less faff than Rocket. We don't know the form of Twin Sisters boiler. Booths first boiler was Lancashire Witch but that was a return flue.
Why do you speak of the Lyon to St Etienne railway in the past tense? From what I understand the railway line that Seguin built is the same as the railway line still in use today, with the exception of a short section at the Lyon end that closed when the station was relocated in about the 1850s, and also one tunnel that was re-aligned also in the 1850s.
I'm not sure I understand? It's all in the past tense. And I know the CF St Etienne-Lyon is still in use.
@@AnthonyDawsonHistory I guess you threw me when you said the line was 56km in length, which I took to imply that this is no longer the case today. But maybe I'm reading too much between the lines. Anyway, thanks for the excellent and informative video.
@@AMOGLES99 no worries! Have a great day

There's an early locomotive wheel in The Smithsonian that's believed to be one of the original wheels from John Bull, it looks nearly identical to the wheels on this replica, so I was a bit surprised. But the comment that it was originally a Stephenson design made sense of it. Interestingly the surviving wheels believed to be from Pride of Newscastle do not have the chamfered spokes seen here and on the supposed original John Bull wheel.
Yeah it was the standard Stephenson type of well until Rocket came along. Solid timber with a wrought-iron tyre and a wrought-iron crank ring. The characteristic sound of the Seguin replica is the creaking of its wooden wheels. The type of wheel now preserved on Rocket with a cast iron hub are a later development. You can see why early solid wood wheels on Planets etc were prone to collapse!
@@AnthonyDawsonHistory Thanks for the reply. It reminds me that when Baldwin built Old Ironsides, copied from an imported Samson or Planet type, he had great difficulty with the wheels. I also presume that this was type of wheel Locomotion originally ran on before the cast wheels were fitted (although I can't remember ever seeing that engine rendered with wooden wheels in any art I've seen).
@@furripupau Locomotion had eight-spoke cast iron wheels. They were....not a success. She was certainly not built with Wilson's "plug wheels". We don't eve know what it looked like exactly or what, if anything, of the locomotive which exists today, is from 1825.
