Dis is Indian Raikways jo kabhi bhi puuri demand puuri nhi krta..it fullfils it in emi's.. and I dnt think a shatabdi will be operatd between be and ndls..dis is only my prsnl opinion...jst for example take lko ndls premium, uske frst run ki all seats are full...sbse pehle uske ac 3 tier full hue..I mean harr jagah ki demands ki bhi type diffr krti hai..jaise lko ndls pe AC coaches are benificial..I will remind daily lko has Lucknow Mail(10 ac coach), lko raj(14 ac coaches), lko shat (17 ac coach) and gomti(3 ac coach)..still d waiting in ac class is high...so shatabdi is nt always successfull coz uske fare bahut high ho jaate hain ...
