नहीं कोई गम, रेलवे से हैं हम - Aman

Preparation of final list of passengers who will board the train at a particular station, clearly specifying the names, age, PNR No, Quota, Berth No, etc. For long distance trains, there are multiple charting stations depending on journey "legs".

chart preparation also includes upgradation & degradation of a pnr too(mostly we see upgradations )

Upgradations ?????

---

Sometimes passengers of lower class are upgraded to higher class automatically for optimum utilization of berths.
