What is maglev? Name a few countries that have been successfully running Magnetic levitation trains. What’s the technology behind this maglev? How does it run? Don’t u think they are far ahead of us? Have we missed the bus?  And when will we be able to travel in that kind of HSR or will it remain a daydream? Do we have that much of resources? Do we need bullet trains? considering the socio-economic conditions?
