Okay... so, I took the risk that day and booked in FC. Only one ticket out of 5 was confirmed before chart preparation and we were pretty tensed. After chart preparation, all 5 tickets got confirmed. There seem to be quite a few tickets in EQ.
There is also an unreserved coach. However, there are limited number of tokens (45) given at station master's office on the morning of train departure. One needs to collect the token and then go to booking office to get the UR ticket.
