Fastest train between Patna and bhagalpur is this train along with Agartala Rajdhani both takes same time 4 hr 25 min...jabki Puri line sayad double hai aur kiul tak 130 kmph bhi hai speed phir bhi 70+ Rajdhani ka speed hona chahiye tha..Bahut sare single route me speed is sector se jyada hai..kya karan ho sakta hai..
