From November 12, you can book a railway ticket online 30 minutes prior to the departure of a train. Railways have also made changes in its system of preparation of chart, which would now be prepared twice. First reservation chart would be prepared four hours prior to departure of a train while second and final one, 30 minutes before the train departs, a senior railway official said. According to the revised rules, booking will be allowed on internet as well as at reservation counters for a particular train, subject to availability of berths, even after the preparation of first reservation chart. Railways have also made it mandatory for the concerned department to finalise the reservation chart four hours before the departure of train from November 12 in order to facilitate passengers to know the status of their ticket and plan their journey well in time. A second and final chart of reservations will be made available before departure of train and handed over to onboard ticket checking staff.
