i agree to that..but the thing is places like NGP, SC, SBC , VKSP are not very well connected to JAT, hence people go to NDLS and change and most of the SF and good trains from these places reach NDLS during peak morning time and then u dnt get good connection to JAT ... for exp, if u travel by tamil nadu , rajdhani , AP exp , KSK , GT , Gondwana ..it becomes difficult to get connection to JAT..
