Do you know the reason behind the introduction of CR Rajdhani ???
It's based on demands of Jalgaon, Nashik and Kalyan- Cities of Maharashtra whose Capital is Mumbai itself.
Same way Bhubaneswar Rajdhani was diverted due to demands from Sambalpur, Chakradharpur, Jharsuguda and Rourkela- Cities of Odisha whose Capital is Bhubaneswar
Same is true for Ranchi Rajdhani to serve Lohardaga, Tori- Cities of Jharkhand...
more...

whose Capital is Ranchi.
Is Malda Town a City of Tripura ?? Is Bhagalpur a city of Tripura ?? Just ego satisfaction nothing else.
Using your logic Kanpur or Prayagraj can demand Diversion of Chennai Rajdhani or Secunderabad Rajdhani as well 😂
