The Indian train displays train coach position based on the previously available historical data. Therefore, sometimes this information changes without any prior notice, it happens because of overcrowding of trains running late on the station, so it is always advisable to recheck train status before commencing the journey. Passengers should reach the station at least half an hour before the train departure time so that they can get enough time to reconfirm the platform number and coach position from the railway inquiry counter.
Note: If you want to get the accurate position of your coach then you should check it after the chart is prepared.
