A train reservation chart is the final seat and berth allocation record prepared before a train starts. For passengers searching chart vacancy, the important part is not only whether the chart is prepared, but whether a berth is vacant between your boarding and destination stations.
GapSeat helps you check chart vacancy by train number, date, boarding station, and destination station. It is not a passenger name search tool and it does not replace IRCTC. It helps you find coach-wise vacant berth opportunities, then you verify or book only through official railway channels.
