Sooner or Later Panipat will get stoppage of this VB, i expect TT of this VB also to change in next 1 year. It maybe pushed back after SVDK VB.
5.50 AM is too early a time for a premium train to depart from NDLS, because it has been introduced in hara-kiri right after TAAG on 1st Oct just because of HP elections, NR didnt tinker TT of other trains to accommodate Una VB at a departure time which is favorable.
