@first blogger :
Charts are not uploaded on the Rly website and that is already replied vide # 25310-3.
Chart pasting timing on the Rly Notice Board (for Charts) appears to be train specific and station specific. It is usually pasted before 1.5 -3 hrs of train's scheduled departure. The timing for Updated view of PNR statuses on the website or on 139 also appers to be train specific and station specific. Post your journey details or PNR No.
