Relavance of 21 s oct 2011 is that from this day onwards this train is rescheduling at 4 am , will it continue till 15/2/2012 ? as we have booked ticket by seeing dep time at 8.35 pm and to reach cst @ 4 am is is wating our whole night , hence i have asked this question and if it is correct that it may dep at 4 am then why indian rail is changing its time to 4 am so passenger like us may book ticket accordingly
