ur point is write but plz understand that,
>when a raj is not from/to state capital or running via state capital,,, we have to b very sure that the rail infra in that area of the country is not gud... DBRG raj is given to connect the whole 7 states of NE to connect wid delhi...manipur, mizoram, Arunachal,nagaland and from lumding even tripura is connected to this and for megalaya its guwahati the nearest station.....
>same for J&K and Chattisgarh,,,, where rail infra is not gud for maintenance of raj.
