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.
