A flying train that has a hydrogen blimp over every passenger car, practical or impracticle?

Stupendously impractical, generally stupid and massively dangerous for a multitude of reasons.

That is impractical.

Remember the Hindenburg.

Not only impractical but ranks right up there with the greatest stupid ideas of all times.

It seems you lack any common sense.

Compartment for passengers under a blimp is about 100X smaller than the gas bag supporting it.
You would have to have a quarter mile of cable connecting the compartments to make room for the gas bags. And they will have to be streamlined to lower air resistance. That would make them longer, and extend the cable. I guess you could make the blimp bags all in one like a huge sausage.
After lifting the compartments and bag material, the weight would be so high as to prevent boarding any passengers.
Motive power for the "air train"? How does that work? Cannot use any propellers on the front of the train, since that would make turbulence around the compartments. Also, a sideways wind will catch all the unpowered compartments and swing them around. Now you are going where the wind wants to take you.
Lots of people paid with their lives when using hydrogen. Helium is preferred but much more expensive and rare. And the US Navy tried almost for many years to use air ships. The early ones crashed in storms. In WW2 their blimps patrolled for submarines to attack. Now the only government use is for "aerostats" that hoist radar units above the southern border.

Your ignorance is profound. VERY impractical to the point of absurdity.

Completely impractical and counter productive.
The friction of steel wheel on steel rails is a minuscule fraction of the aerodynamic drag of something as large and bulky as a blimp moving at the same speed.

Hydrogen is extremely flammable ( read up on the Hindenburg disaster ).
How will the train propel itself if it's not on tracks?
