Please note this is NOT an official site, nor are people concerned with ticket bookings/cancellations/alterations. If you have to change boarding, please go to nearest Railway booking center tomorrow morning (today being Sunday, it closed at 1400 hrs IST i.e. 2.00 p.m.), with a letter and showing proof of identity and request change of boarding with the Chief Reservation Supervisor. Note however that if you want refund of charges between Jhansi and Bhopal, your ticket will be cancelled and fresh ticket will be issued, and you may lose your seat, if there is no vacancy or you may come on the Bhopal waitlist. It can be vice versa also i.e. if you are travelling from Bhopal to Jhansi. If there is availability they will alter your booking, and collect the fare between Bhopal to Jhansi. Good wishes.
