Problem sir, there lies a stoppage in between ERS & TCR.
Its quite risky, as TTE can transfer ur ticket to uncleared RAC/WL Ticket holder.
I once boarded in Gyan Ganga from Pune to BSB, with unreserved ticket in 3A.
TTE awaied till Ahmednagar for the vacant berth (reserved from Pune), before alloting me. But i am sure, ifhe would had any RAC/WL uncleared,...
more... he would hve allotted it, rather han awaiting till Ahmednagar
But u cant guarantee this, as rule doesnt compel TTE to await till certain distance!!!
