Your journey date 19/9/2019 it means approx 40 hours, wait for last minute changes of actual status of your ticket, checking after everything about your ticket and my knowledge saying it will be confirmed # it is your first question's answer.
And next is Q-2 & Q-3 :: read it
**RAC ticket most of the time get confirmed after the chart prepared & train depart from its source station. In that case only you have to talk to TT regarding your RAC ticket. He will update you with whatever the current status...
more... of your seat is going on.
RAC passenger is given empty berth which will assigned to them only in these 3 case:
If there is any last minute cancellation of the ticket.
If any VIP quota or others remain unsold.
If any of the passenger book ticket but didn’t came.
***Indian Railway ensures the certainty of your travel in the particular train of which your booking has been done, means you can travel in that train but there is no fixation or guarantee of a particular berth. No berth assigned to you in RAC to sleep at night. You can sit only. Sometimes through RAC u get half of the berth to you & half of the berth to other person, so 1 seat is divided between 2 passengers.
Thanks for asking.
