The iconic carriage of the steam era which recorded both 100 mph and 126 mph record. Great presentation by Bob , helped us understand the various instruments inside. :)
I’m a lifelong American Railfan and Steam Enthusiast, and your museum is a must see if I ever end up ‘across the pond’! British Big 4 Passenger Equipment just drips of elegance and class. Truly the ‘Beauty’ to America’s Beasts!
Watch the movie _Danger Lights_ on RUclips - it's a 1930s film based around the Milwaukee Road railway, and some of the best early footage we have of trains of that era. Featured in the film is a Milwaukee Road dynamometer car - though we don't see inside it, from the outside it looks _very much like_ this British counterpart. Very probably both carriage builders were sourcing their equipment from the same scientific instrument concerns, or at least from concerns which had both licensed the same designs, so it's likely the interiors would be similar. And the exterior, at least, is just as much a work of art as this one.
I personally got completely say that I personally saw a dynamometer car @ the B & O Railroad Museum, so I personally do specifically feel quite aware of how a dynamometer car operates! Besides, it's basically quite clear that dynamometer cars certainly would basically also apparently be fitted with an official complete sleeping quaters for the people that are working over in the dynamometer car can easily get some shut-eye in between each shift! Plus, you'll be very shockingly surprisingly pleased to happily know that I seriously do personally just suddenly recently recall seeing a video on RUclips several times recently featuring Tornado as the custom-built L N E R class A1 Pacific type of steam-driven railway tender locomotive designed by Sir Herbert Nigel Gresley's successor managed to easily reach 1OO MPH top speed with ease despite several speed restrictions in several locations during the official test run from York to Newcastle followed by the return trip to York!
I’ve always loved this dynamometer car since I first saw it in photos behind my all time favorite LNER steamer: W1 No.10000. Thank you for helping preserve this masterpiece of LNER technology!
Absolutely incredible, I've seen these cars and similar set ups but wow, the minds behind this must have been vast. All that information like a modern obd reader on any old basic car. Consistently blown away by these insights
I seriously gotta personally just suddenly feel quite pleased to happily mention that I seriously just suddenly came up with the officially well-knowingly clever idea of completely building an officially amazingly exact copy of the famous record-holdin' L N E R class A4 Pacific type of steam-driven railway tender locomotive designed by Sir Herbert Nigel Gresley himself in Doncaster during the official 193Os(July 3rd of the year of precisely 1938 respectfully)Mallard alongside a specifically wonderfully great newly improvable L N E R dynamometer car fitted with an official set of knuckle coupling devices on each end to allow 'em to pull American-origin rolling stock with ease alongside recreating the officially well-knowingly obviously famous 126 MPH(2O2.58 KPH) top speed record WHILE also apparently pulling a train of Amtrak passenger coaches behind the dynamometer car as the passengers onboard can easily use GPS compatible devices to help with recording the record!
You know you e made it, when this is your office I was lucky enough to be a Lookout Man, on the Crewe Engineers Saloon at Shrewsbury. Best part was Cucumber sandwiches and Ginger beer. Testament to British Engineering Excellence .
What a beautiful locomotive. I was at Stockton in 1975 and at the Great Gathering at both York and Shildon and have plenty of spare timetables to Shildon if anybody requires one. Only cost would be postage so about £1.
What an artpiece the whole car. One can just wonder how nice instruments there were at that time. O2 was not possible to measure directly but CO2 measurement system was available for instance to indicate combustion efficiency.
Comparing a modern measuring car with this, they look quite different and obviously the instruments have changed a lot, but what they do hasn't really changed at all. But man, that is one big DIN plug in that old car :D
At about 1:30 the curator says you could do much of the measuring with an app now. The current method of tracking speed is still physical, I believe. Driverless stuff like the DLR count wheel rotations to track their position, albeit with regular balises to confirm position. Speedos in cabs are presumably mechanical or electro-mechanical, as in a car.
Could 6229 get an episode ? Also I've visited the nrm so many times over the years, so many boys would dream to get in that carriage, I also spotted the protective bags on your shoes. And does anyone know if the original recorded paper of the 126mph run is still around?
Please do not forget the HST as a whole train was the " Railway " answer to the problems the APT was encountering at the time, HST used good established engineering answers to correct issues that the technology of the day could not,APT at the time was a leap to far for the bofins but the principles came through in the end with Pendoleneo. Sadly the government of the day pulled the plug on the money .
I love this engine for the record it made and still holds, sadly none of the engines here in the U.S. have ever come close to mallards record but if you want a famous engine look no further the Union Pacific’s 4014 of the Big Boy class current holder of being the largest operational steam locomotive in the world
@@FreeManFreeThought Let's face it. There are probably stretches of track in the midwest that are a perfectly flat, straight line for half the length of the UK, so they've got plenty of time to build up speed!
Ian Johns Be it noted that "Mallard" attained this speed down Stoke Bank whereas the DR 4-6-4 #05 002 travelled at 200.4 kph (124.5 mph) on virtually level track. But a fine and most interesting video nevertheless!
A most interesting presentation, thank you. But, I have to point out - it is not 'scrumbling', it is 'scumbling'; perhaps you were prompted by memories of childhood scrumping?
Yes folks, if near York do visit the National Railway Museum. Before watching this I though the dynamotor car just measured speed! What an idiot! Very impressive!
Technically the purpose of a dynamometer car is suggested by its name: it measures drawbar pull at speed (which can be mathematically converted to horsepower). I was hoping to see a technical reference to the timing standard used, and a high-resolution image of the high-speed portion of the trace with a discussion of how the amended speed of 126.1mph was extrapolated from it.
Which is probably a timing artifact; there is no credible way to explain the acceleration from the previous timed section or braking for the following. As with 5550 (or a Milwaukee A) it would be possible to replicate the PRR Atlantic in question and test it, but it's highly unlikely the result would be 'proof of high speed'
Well, i suspect its a multitude of reasons : This episode wasn't about Mallard itself, twas about the Dynomometer car. 2, the damage was all internal and not really something you could see. 3, and most importantly, the damage is no longer there ! It was fixed after the run and loco kept running well into BR days.
I wonder if it would be possible for her to break the record. The longest line of straight track in the US is 79 miles. That could be the ticket for record breaking.
Duddington thought that with a bit more of a start he could have reached 130 that day, and frankly I believe him. The problem was with the inside connecting-rod big end, which was overloaded past the limit of the hydrodynamic lube film because of overtravel of the middle cylinder valve due to whip or lost motion in the conjugating gear. This would not in itself likely have prohibited reaching a higher road speed, as it would not have been noticed until Duddington slacked speed (at which time it would have started knocking). For all the would-be whiners (American and otherwise) the big-end 'fix' -- once the need for it was realized -- was rather quickly made, and even in the absence of a means to reduce the high-speed overtravel it solved any recurrence of that particular failure.
In the true sense of the rules of setting a speed record the Mallard failed as it was a specially set up attempt with only the driver and fireman in the engine and 12 personnel in the dynomomitor car, plus 2 or 3 lightweight aluminium articulated coach sets without any passengers, pulling at most 260tons. It managed 126mph down-bank for a distance of 100yds before running it's main bearings and having to be towed back to Doncaster to be repaired, it had previously spent 6months there being set up to try for the record. The previous holder of the record of 114mph, the LMS Coronation was hauling almost 600tons with every seat in the coaches filled and it did not require a long downhill section to achieve this feat, this was a new scheduled service from Euston to Crewe, after the tender was refilled at Crewe the Coronation continued in service until the start of WWII without any major service requirements, unlike the Mallard the Coronation could have done the high-speed run in the opposite direction (as per the regulations for speeds trials). The above details re: Mallard, are taken from the official LNER records.
Land speed record going downhill? Can't wait for the day, when someone with enough time & money just drops a live steam locomotive over White Sands Test Range from 40'000 ft. for a new record. I find it arrogant & offensive to be proclaiming greatness amidst grand controversy. Not only did the engine go downhill, it broke doing it, so it is unknown, if Mallard was actually providing the power to reach the recorded top speed. Any other land speed record has requirements for validation, that Mallard, to this day, ignores. A measured mile, with a two way run, to be repeated within an hour... Yep, great big pat on the shoulder for a job well done. Btw, nice touch banning the LMS from running that section of track - imbues confidence, doesn't it...?
The dynamometer carriage is such a credit to the tradesmen who built it - so much beautiful timber work.
and brass those gauges are gorgeous
Whoever did the hand lettering on that car is an absolute master.
I don’t think I’ve ever seen a more convincing drop shadow and bounce lighting.
The technology being used in a 1906 carriage is quite surprising. I’m impressed that they could do all that.
Presumably instruments were added during the period 1906 to 1918ish: ruclips.net/video/6x3TGPeImOc/видео.html

It was on Scotsman's run too? Didn't know that fact, how cool!
@@owenmeschter9888 yes he mentioned it at 2:53 :)
That Dynamometer Car is so WONDERFULLY Jules Verne . As Analogue as it gets .

Magnificent insight can't believe how they were able to record all that telemetry back then!

When I visited the National Railway Museum before the Covid 19 outbreak the LNER Dyernostic Coach was my most favourite Coach ever
Another really interesting video. It is great to see inside the exhibits.
I seem to have missed the dynamometer car when I visited the NRM in 2019.
I love your explanations and the passion you have for steam locomotion! I definitely must pay York a visit to see those monsters up close.

Amazing how that dynamometer car records the speed of the Mallard!

Thanks really fascinating and enjoyed watching!
Wonderful coverage! More please 🙏 😊
this series is very good
Well done Bob and the team. A brilliant video - actually more informative than just visiting NRM. Still love the museum though!
Great video amazing piece of kit .
Great video what a marvel in engineering ,they do not make them like that anymore.
Great stuff, thank you.

That coach is amazing 😮

And does anyone know if the original recorded paper of the 126mph run is still around?
Fantastic piece of British engineering
Brilliant that was very intresting. Would the car still work as a test car today? if it was coupled up behind a steam locomotive.
It would be MOST Cool to see it coupled up behind The Gresley - or maybe Tornado on a run!
It's illegal on mainlines as it's wooden bodied
It's interesting to see you've got you're shoe covers on I take it based upon that not many (if any) persons are allowed inside the Dynamometer car
We try to look after it!
I have the model a bit pricey but it looks great with my mallard locomotive.
Always wanted to get the thing out and test how accurate it really can be over and over again. But we are not allowed to

None did so legally, or officially. However some are rumoured to have gotten close to or surpassed Mallard's record in the eastern US.

But that loco was hauling a lighter train, I think - so the performance is comparable.

The title needs the word "official" because remember there had been an un official claim from an earlier year with a speed of 127.1 mph

Why did you not show the damage that was done to the drive train on the locomotive? I was most disappointed by that omission.
Well, i suspect its a multitude of reasons : This episode wasn't about Mallard itself, twas about the Dynomometer car. 2, the damage was all internal and not really something you could see. 3, and most importantly, the damage is no longer there !

I went a few days ago someone tell me what happened to the wall of model trains in the tunnel on the way to the great hall
I wonder what all that equipment looked like to the average person on the street back then. ¿ Witchcraft ?
Millard could have went faster but the driver knew that the main axle bearing would over heat, I believed on the day he pushed it as far as he could….
Duddington thought that with a bit more of a start he could have reached 130 that day, and frankly I believe him. The problem was with the inside connecting-rod big end, which was overloaded past the limit of the hydrodynamic lube film because of overtravel of the middle cylinder valve due to whip or lost motion in the conjugating gear.
