Dekhiye amit bhai...indore delhi aur jodhpur delhi ke b/w rajdhani exp shayad hi IR consider karega....actually i don't think other than a goa rajdhani and agartala rajdhani (after gc),IR will even think of introducing any other rajdhani...just see the eg of ltt nzm a.c exp...this train not at all different from rajdhani,it has pantry,lhb rakes,full a.c and aggressive tt,but still IR hesitated to name it as rajdhani,so its just an a.c exp.... But instead agar demand hai kisi route pe,toh rajdhani ki jagah,normal a.c exp ya sf exp jyada sahi rahega....and i believe due to less fare and more speed,a.c exp are present trend of आम आदमी...;-)
