  2. You have a mistake on the map: At the beginning of the XIX century, Finland was part of the Russian Empire. As well as Poland, Estonia, Latvia, Lithuania, Ukraine, Belarus, Georgia … And all this was before the formation of the USSR.

  3. I'm at 3 mins perhaps you will address this but the thing about trains it the steel-on-steel wheels that reduce the roll resistance. A bus (what this is here) has normal wheels with massive roll resistance. Also, this isn't a monorail as it has just a curved road under it, making it have the drawbacks of a monorail, complicated gates. A curved road would have the nice effect of suffering far more from environmental effects such as rain and snow.

  4. 1. A huge wheel that will receive huge centrifugal forces. No one calculated the real capabilities of the real wheels that they could produce, or, as is typical for Soviet engineers, they doubled these indicators to impress the government

    2. Turning in the lodgement is possible exceptionally at significant roll angles, because the wheels are not controlled in the horizontal plane. Therefore, turns are performed exceptionally at the speed set for them. the curve could be built as a lodgement for a bobsled. So that it can be passed at low speed along the lower, more horizontal part. However, then the train will try to pass it in a straight line, constantly climbing on board, which can lead to overturning. That is, this option is not suitable.

    3. Huge losses due to the friction of a soft wheel. Yes, it is made of hard rubber, but each of them carries a dozen tons of static load, not to mention dynamic loads. That destroys the economic feasibility of such a system, for which classic trains with steel wheels are built.

    4. Resistance of the track to weather conditions. Snow makes it impassable. To drain the rain, you need a powerful drainage located at the bottom – the most loaded part of the track. as the seasons change, the concrete track will deteriorate due to the freezing and thawing of water in the cracks and drainage.

    5. Most of the destruction and potholes will be at the entrance and exit of curves. they will cause a resonant rocking of the train, which will require a speed reset. That is unacceptable in curves, as I wrote earlier.

    6. Soviet builders. There is no way they would build a perfectly flat concrete track that would not distort over time due to temperature changes and the movement of supports in the ground. And this again leads to a resonant swing. Therefore, still in Russia, classic flight tracks, which are much easier to maintain and repair, do not allow the fastest Russian trains to run at a speed of more than 200 km/h.

  7. Fascinating idea. But they wanted to build this in northern Russia. The temperature variations between summer and winter would crack concrete all the way. Can you imagine the constant repairs when you’re talking about hundreds of kilometers?

    Add in storms, snowstorms, etc., with all kinds of snow and debris that needs to be cleared out.

    It’s a beautiful concept, but not practical for the climate and distances.

  13. Hey Nick, can you do a video on the p51 fsw (forward swept wing). I found out about this plane when searching for forward swept wing fighter jets. Can you also make a video on the maus?

  16. It's more than a slug or a snake? but let's lot forget it's a slimy earthworm indeed!!! That Soviet monorail testbed in the film is more like an expensive kiddie train ride if you know what I mean?!!

  18. There is a fundamental flaw, the wheel will try to climb out from the trench. Its diameter changes which means the center of the tire will have high speed than the edges. This in turn means the edges will drag along the trench and try to climb out with gravity pulling it back down until the forces equalize.. and then you get the wobble. Most likely the front and rear wheels will try to climb the opposite sides of the trench too, making it snake around the half pipe. It needed two set of wheels, at an angle to make it stead, and most likely some kind of limited slip differential.

    To make a monorail with one rubber wheel the "road" has to be convex and the wheel concave. That way the edge of the wheel rotates fastest and it will self-center. If you look at old belt drive, they have convex, a "bulging" wheel and not concave. It looks counter intuitive until you start to look at speeds across the belt width. Everytime there is an error the belt will self center on a bulging wheel. With a tire on a trench the mechanism is a reversed but we are still looking at speed differences across the width of the tire.

  31. amazing, I am from the czech republic and I do not like WE THE SLAVIC BROTHERS & SISTERS fight each oeather, we hav e athe same background, we have the same believies, we should unite under one slavic flag, polich, russian, slovakian, czech, lithuanian,,,,etc,…. weare devidided, and who devides US, THE BROTHERS, & SISTER(''!!!!!!!!') the us????????? we are SLAVIC!!!, and not in the jump suit and other nonsence, BUT TRADITIONAL VALUES,………. VALUES OF TRADITIONAL FAMILY……. TRADITIONAL HABITS,…. each different to each nation… be it Poland… Russsia….Ukraine…The Czech Republic.Slovakia….And HE HEROIC HUNGARY, HWO STAND FOR WHAT IS RIGHT, (and i personaly am gratful for hungaryianan peply to resiit the debouchary of foreign nations, pleas protect US! CZECHS AND ATHERS, AGAINS DEBOUCHERY, OF OTHER REGIMES, PLEASY….. HU Peple no.1 I Do not care if I would be arrested be debouchreres czech govermnet, who betreyed, Its peaople, Icare 4 Justice, For democracy, 4 rights of family values,, I do pleas the people of Humgary and Poland Nor!!!!!!!!!!! to stop fight fo the RIGHT VALUES

  33. M I Yamashook had to be an accomplished engineer and visionary to bring his idea from concept stage to research prototype. Testing reveals design weaknesses and perhaps fatal concept weaknesses, this alone may have been enough to cancel the project. Scale of economics was more likely the strongest obstacle, railroad infrastructure, paved roads and emerging passenger aviation had already captured the attention of the planners. Military flexibility would also be a factor.

    No doubt with sufficient ( but not excessive) resources this design could have achieved some viability. Perhaps there were just too many major areas in need of simultaneous refinement.

  43. When the Siberian tundra becomes farmland.
    And Canada has 'The Wild Wild North' as the next frontier to exploit…
    And 'Colonize Mars' becomes a real 'Colonize Antarctica' instead…
    There may yet be a need for something like this, maybe with gyrostabilization and some electromagnetic siderail repulsion help.
    The idea of cheap to build long range transport for a next frontier might yet see its heyday.

  44. Maybe the same self centering groove, but the track is a screw-foundation elevated aluminium mesh?
    Then a magnetic effect would levitate the train.
    Also, the driving wheel could engage with magnetic metal in places along the aluminum mesh like gears to provide traction on inclinated track.

  46. Concrete roads are bumpy as shit… that's why asphalt is preferred… that train would be bouncing all over the place at high speeds and be super easy to derail with those massive wheels that are so much taller than the track (motorcycles dont like driving in ruts, they want to climb out onto the high ground… that's why it never got past testing lol

  49. the wobble from the train looks worse than it should be, because the so called track looks to me like it is made of cheap wood strips, I bet if they did it properly it would of had better results, and today we know to make very smooth floors for warehouses and supermarkets so I'm it can be done for a modern concrete monorail.
