Toy Levitron-Magnetic, Or, Electromagnetic, Floating Train
So either, an
- Levitron-Magnetic( non-electric permanent-magnet ) Floating Toy Train moveable along a track
- Or, an Electromagnetic Floating Toy Train moveable along a track
It's odd how none of these appear on the market, since they in no way involve overunity.
There are at least two Electromagnetic-Floating-toy-Train prototypes I have seen made by different people, but I have not seen anyone bothering to make a Levitron-Magnetic( non-electric permanent-magnet )-Floating-Toy-Train. Some time ago, I noticed that someone else had thought up the idea of a floating-toy-Levitron-train( non-electric permanent-magnet ) significantly earlier than I did.
Times of past..... (sigh)
We used to have permanent magnet levitating train toys
Long before there was such a thing as the Levitron train
Turns out there's not much of a market for these things anymore
Kids want their I-pods

I believe you, that you successfully achieved 'full-magnetic-levitation' just by using 'permanent-magnets', 'visually' defying the laws of 'magnetic-levitation', since I can see various ways that that could be done, and another member her claimed the same thing.
However, I am sure that there never was a 'fully-levitating-toy-train' that just used permanent-magnets, which would 'visually' have defied the laws of 'magnetic-levitation', not only because it would have been suppressed and not manufactured, but also because I have never found any hint that there ever was one sold anywhere.
I have also not even seen that anyone has ever built a 'Levitron-Train', which is odd, since it defies no laws of science ( the earliest mention of this idea, was made by someone only a few years ago )
( people definitely want to buy these things )

I think the very easiest way to build a fully-levitating-toy-train just using permanent-magnets would be to make a straight section of track, making each of the rails out lots of round-button-shaped-magnets to form two long cylinder-magnets, each cylinder-magnet being an individual rail,
- however, you could possibly also slightly space apart the individual round-button-shaped-magnets , either for traction reasons, or just a longer track
- the levitating 'train' itself could be a lighter/weaker version of an individual rail-design in this idea, AND, YOU COULD HAVE SMALL NON-METALLIC WEIGHTS HANGING FROM THE TOY TRAIN TO KEEP IT IN-BETWEEN THE 2-RAILS, TO PREVENT IT FALLING OF THE TRACK.
( I posted more advanced methods previously in other threads on this site, but they would definitely be more difficult to build )

There could be also a completely different way of building a fully-levitating-toy-train just using permanent-magnets , that would be to copy the hoverboard invention, so it would levitate above a suitably designed copper track,
but I'm also wondering if could it be done without fast rotating magnets, like the basic magnet down a copper-pipe effect, and it could have standard ground-wheels to enable it to get up to a high enough speed to float.

That toy-floating-train video you just posted, that train relies on the transparent-plastic side-barriers to prevent it from falling of the track, which I think you already know, so it no where near qualifies as full-levitation.
All of the designs I have posted are designed to be fully-levitating, including the much-simpler designs( easier to build than my previous designs ) which I posted in my previous post on this thread.

Another more recent video, looks like it uses a series of Levitrons.

Apparently in that one, the 'floating-magnet'( magnets ) always touches one of the rails, it always touches 'one' of the 'two' rails of the track.
( Another member on this site was the one who spotted how it works , and thats how I know how it works, but the first time I saw it, I also thought it was 'full-levitation, it doesn't defeat the laws of magnetic-levitation( but it is not far ), an excellent invention anyway )

As far a I have been able to see regarding this one, it uses the exact same technology found in all these 'floating-globes/cars' that you see on ebay, basically, the floating-component is just a permanent-magnet which is floating above an electromagnet( electromagnetic coil ).
And inside the Base/Track of this train, there is actually a device which moves the electromagnet( electromagnetic coil ) along the track, but you can't see that since the base is closed.
It doesn't defeat the laws of magnetic-levitation, but is also an excellent invention.
It may not be feasible to make produce it as a toy since sufficient lengths of track could be costly, but I may be wrong.
You could think up all sorts of modifications to how it works, to make it cheaper to produce.
( There is an earlier( as far as I can remember it's earlier than this one) one on youtube somewhere, by a different person( I assume ), which uses a very similar method, but the train is crammed full of electronics and electromagnets?, it's very hard to find that other one, and I didn't find exactly how it works, although it certainly does not defeat the laws of magnetic-levitation either )
( Only regarding a levitron-train, I can now see why no one would bother building one, because of the other levitation-methods.
However, I should clarify( what I was searching for ), I thought someone would build a totally-non-electric-levitron-train, just to prove you could have a fully-levitating-levitron-train just using technology before electricity was very commonly available, so either :
- a manually spun fully-levitating-levitron-train
- a steam-powered fully-levitating-levitron-train( or other fuel-engine, or stirling-engine )
- or even , a wind-up fully-levitating-levitron-train )

But anyway, I was hoping someone would build a 'Non-Electric' And 'Non-Levitron' 'Fully-Levitating' model-train, just using permanent-magnets, I have certainly posted enough designs.
( they sell very tiny neodymium-cylinder-magnets, or even those small ball-shaped-magnets( obviously they still have an N and S ), using those would be a much cheaper way to make one )
Would not a 'Non-Electric' And 'Non-Levitron' 'Fully-Levitating' model-train be a linear version of a magnet motor?, not seen any of those.
If you mean a wind-up or steam powered version of a levitating train, then yes, I can see that being possible.
Sorry, not seen any of your designs.
Without getting into a grotesque argument about what 'true magnetic levitation'
really is:
The toys of the past had constraining tracks that kept the 'train car' from flying off the track.
They did truly 'float', and the child could push the car and it would float around the track.
They were no different in construction than the larger trains we transport people in today.
Only thing missing was the powered coils that drive the train without the force of the child's hand.
We NOW have the technology to do this, using electromagnets (see floating blue tooth speakers)
Permanent magnets change over time when forced into repulsion.
So, even though we can stabilize a device to free float, this only occurs for a short time
until one or more of the magnets weakens and the conditions change that kept it stable.
The so called "laws of magnetic levitation" are often taken out of context
'Movement' does not necessarily have to be unidirectional, nor does it have to
continue moving in the direction it originally moved in.
But rest assured there is always motion. The field itself is moving.
Even though we perceive it to be motionless in a permanent magnet.
It is this motion that manifests itself as 'force' when we interact with the field.
The quantity of magnetism that is moving is what determines the magnitude of this force.
More modern (stronger) magnets will weaken faster than older ceramics when forced into
repulsion for long periods of time- making these older ceramics desirable for constructing
levitating devices.
The laws of magnetic levitation do not in any way, shape, or form prohibit such levitation.
They simply describe the mechanics of such levitation when it occurs.
Take for example two hollow-cylinder magnets
Diametrically magnetized, one small enough to fit inside the other
And of opposite polarities.
You now have a fully levitating magnetic system.
They will move away from each other along the length of
the cylinders.
If one magnet is held stationary, the other will move along
the axis. If the cylinders are of sufficient length, it becomes
a mode of self-powered transit.
