Charts are prepared on the basis of departure time from the stations to which the Reservation Quota pertains. A train has multiple charting based on different Quota provided for the train.
The phenomena are basically as follows:
1. Reservations are suspended in general before 4 hours of departure of the train from the station where the operative quota is...
more... charted or 08:00 PM (Sunday or specific holidays 02:00 PM) which ever is earlier.
2. For the trains departing on a day up to 12:00 noon, reservations are suspended on the reservations closing hours of the preceding day.
3. This suspension is for the public at large and Supervisors have authority to go on issuing for VIPs.
4. And hence, charting can be done anytime after reservations are suspended. Accordingly for non important trains, charting is done more or less 4 hours before the departure time for trains operating from 12:01 noon to 11:59 midnight.
5. For trains operating beyond 11:59 midnight to 12:00 noon, charting is done anytime after 08:00 PM and hence it can range from 4 hrs. to 16 hrs. in advance.
6. In case of a Sunday or a specific Holiday, this advance period may range from 4 Hrs. to 22 hrs.
7. Yet, charting for the trains which have much VIP inclination is quite delayed and is witnessed even before 50 minutes only.
8. A charting for a station enroute to which a different quota applies, can still be done from the originating station of the train if the required leg (journey span) was available to the origin.
