First off, welcome to Hypography var!
That's quite an impressive first post.

Firstly, its aerodynamics are very poor and cannot be improved due to screening effect (interface between the vehicle and ground), secondly its track structure is very expensive not only to build, but to provide corridors (ROWs), thirdly train's mass per passenger is excessive.

Indeed. As someone who works, mostly, in the transportation field, I would certainly agree with all the statements above.
I would add that highway/road infrastructure is enormously expensive as well, both in production and upkeep. Bridges are a civil engineers "whittle stick".

Such a transportation system has already been invented, this is what a high speed 300 km/h transportation module looks like...

Do you have a link to the description?
Nevermind, I think I found it?

This is the most aerodynamic vehicle in the world, Cx = 0.075 compare it to a Porshe Cx = 0.26! Specific geometry of wheel-track interface give rolling resistance twice better than a train, the vehicles mass is 180 kg per passenger. All this combined give fuel economy at 300 km/h of 1.7 kg per 100 passengerxkilometers!

I have to ask...What propels this?

Importantly the track structure is very light 120 kg/meter and cost 10-12 times less than magnetic levitation track.

What is it made of?

Vehicles are provided with automated control system that facilitates frequency of 40 seconds.

I don't understand this. What is the ACS and why a 40s frequency?
