Its like Duronto since its inception..But woh maza jab ek train SF tag ke saath iss tarah se chalti hai with Pure LHB rake,130 kmph MPS Of Rajdhani,more than a dozen OTs in every run,non stop schedule toh uski baat hi alag hai..Duronto ka tag lagne se bhi yeh aise hi chalegi aur fare bhi badh jayega..SF ke tag ke saath Duronto ke run ka maza hi alag hai without need of any baishaki (Duronto tag)..;-) :-D
