My friend, I would request you to do a proper homework before you conclude :)
Assam capital Dispur and Gujarat capital Gandhinagar are just sub-urbs of Guwahati and Ahmedabad respectively. So definitely Rajdhani are connecting State Capitals with the National Capital. Also the North-East is a delicate issue and they enjoy extra previledge.
However, you don't like the red then I'm withdrawing it. But admit it that your concept is all wrong.
