Yes. You would be given a seat accordingly. If you are travelling towards Hatia, you would be given a seat at a coach which would be runing towards Hatia. Or else, the opposite. You dont have to worry about dat. After you arrive at the platform, just check out the chart (which is generally prepared between 30 min to 3 hours before scheduled departure).. And in the chart, it would be mentioned dat in which coach and berth are you alloted. Nywz, HAPPY JOURNEY IN ADVANCE....
