Shatabdi is very slow on this route. slower than many other trains. and IR is asking for a premium on top of that. Here in Delhi also , KLK Shatabdi runs closely to UNA JS .. but both of them are popular with different types of passengers . even JS , Saharsa Gareeb Rath and ASR Shatabdi depart at the gap of 10 mins from UMB. Then also Shatabdi and JS gets pax from here towards Delhi !
