Sir, First of all pls note the charting time of train. Its 9.10 am tomorrow.
As per seating allotment there are two possibilities:
1. If your ticket gets confirmed you will get single berth allotted for you.
2. If your ticket remains at RAC then you have to share your berth with other passenger.
Whether...
more... your ticket gets confirmed or stays in RAC, you can know after charting.
*Auto Upgradation means if some seats of 1A (AC First Class) remain vacant after charting, then the passengers of 2A opted for upgradation will be promoted to upper class.
Good luck & Happy Journey!
