Vande bharat is not high speed its semi high speed
High speed technology me bhut se develop nation b invest nhi kiye due to no use for them
US didn't did being so develop & rich nation..
Bcoz their air sector is cheap..

They cant connect everypart with airport as it requires land..
U cant built even floating airport everywhere (they have that too)
So they invest in high speed technology & built bullet trains
Then they invest in maglev but which comes out to be costliest..
Where as in India we are converting our ICF to LHB coaches that too possible by Suresh Prabhu sir and piyush goyal..
110 to 130 kmph was dream for normal trains
