i have to travel from lucknow to chennai by train no. 12511 on 19.05.2011. The reservation is not yet confirmed. when would the chart of the train be prepared and i will come to know whether my tkt is confirmed or not. This train departs from gkp at 06.45 hrs of 19.05.2011. Earlier to this i went from tr. no. 12521 which probably starts from barauni and i came to know about the status (PNR) in the evening of a day in advance of my journey from lucknow. Now the schedule for preparation of chart for train no. 12511 will remain the same or not?
