the world’s most expensive toy car track is probably the a scientific experiment for magnetically leviated transport systems.
As you can read here the cars are actually hoovering by means of high temperature superconductors (like the little piece shown on the left (image from here)).

Just the sentence “The model can be used [for] a fast transportation system to students and adults.” seems mysterious to me – what about chimney sweeps, locomotive drivers, and other minorities?
