You can probably guess why these toy trains are not mass produced for the kids. I have posted superconductivity earlier on here but this time its cool to see it applied to a toy, frictionless, smooth and so silent. Just so beautiful! VIDEO->

Identify the age range for which the toy train track should be designed. Manufacturers clearly label on the packaging the age group of the children for whom they make their toy train sets.
